<h3>Intro</h3>
|
|
<blockquote>
|
|
The GKrellM structure is a framed stack of monitors and there are two
|
|
monitor types, Charts and Meters, which have background images applied
|
|
to drawing areas. Charts have two drawing areas, the chart area and the
|
|
panel area. Meters have one drawing area, the meter area.
|
|
Most theme images and options are applied at this level and many can
|
|
be specified to apply to a particular Chart or Meter monitor.

|
A theme is a directory containing theme images. A theme directory may be
|
|
any of several locations:
|
|
<pre>
|
|
~/.gkrellm2/themes/THEME_NAME/
|
|
/usr/local/share/gkrellm2/themes/THEME_NAME/
|
|
/usr/share/gkrellm2/themes/THEME_NAME/
|
|
/usr/share/themes/THEME_NAME/gkrellm2/
|
|
~/.themes/THEME_NAME/gkrellm2/
|
|
</pre>
|
|
The last two locations require gkrellm >= 2.1.16 and are compatible with gtk2
|
|
theme locations. They are
|
|
convenient for installation when making a meta theme including gtk2, gkrellm2,
|
|
and possibly other themes. The <i>/usr/share/themes/</i> directory component
|
|
may actually be something different depending on how gtk2 was installed.
|
|
<p>
|
|
If a
|
|
"<b>gkrellmrc</b>" file exists in a theme directory, it is parsed for theme
|
|
specific settings such as borders, margins, colors, and krell parameters.
|
|
The theme directory also has images for the frame, background images for
|
|
each of the drawing areas, and detail images (decals and krells) which
|
|
are drawn on panel and meter areas.
|
|

|
|
|
|
|
|
<h3>Terminology</h3>
|
|
<blockquote>
|
|
|
|
Chart monitor - A monitor type which has two background areas - a
|
|
chart area with a bg_chart image as a background, and a panel area
|
|
with a bg_panel image as a background. Labels, decals, and krells
|
|
are drawn in panel areas.
|
|
<p>
|
|
Meter monitor - A monitor type which has a single background area type - a
|
|
meter area with a bg_meter image as a background. Labels, decals,
|
|
and krells are also drawn in meter areas. A meter monitor may have multiple
|
|
meter areas vertically stacked.
|
|
<p>
|
|
Decals are pixmap graphics or text elements such as LEDs, button images,
|
|
toggling labels, etc. usually placed in fixed locations in panel or meter
|
|
areas. These may have transparency and may overlap.
|
|
<p>
|
|
Krells are pixmap graphics which are programatically moved horizontally
|
|
across the face of a panel or meter area. They implement meter indicator
|
|
movements, moving animations, and slider controls. Krells may have
|
|
transparency and they usually move over decals.
|
|
</blockquote>
|
|
|
|
<h3>Image Structure</h3>
|
|
<blockquote>
|
|
All theme images are either base level images which are in the toplevel
|
|
of the theme directory, or monitor specific theme images which are placed
|
|
in subdirectories of the toplevel. All base level images have a default
|
|
which will be used if it is not provided in a theme.
|
|
<p>
|
|
Excluding detail and optional images (see below), here is the base set of
|
|
images required for a theme change in GKrellM (.png used as an example).
|
|
<pre>
|
|
F : frame_top.png
|
|
f : frame_bottom.png
|
|
: frame_left.png
|
|
: frame_right.png
|
|
c : bg_chart.png a chart area background
|
|
p : bg_panel.png a panel area background
|
|
m : bg_meter.png a meter area background
|
|

|
|
: bg_separator.png a chart area data view separator
|
|
</pre>
|
|
This is a side section view showing how these images are used to build
|
|
GKrellM. frame_left/right and bg_grid are not shown and not all
|
|
monitors are shown.

|
|
|
<h3>Theme Image Names</h3>
|
|
<blockquote>
|
|
The background areas, krells, or some monitor detail images can have
|
|
a monitor specific custom image substituted for the base level default
|
|
image. For a custom image to take effect, it only has to exist in the
|
|
monitor specific subdirectory.
|
|
<p>
|
|
Here is a list showing the image naming structure in a theme directory.
|
|
Images may be .png as shown or .jpg or .xpm.

<h4>Custom images in the theme subdirectories</h4>
|
|
|
|
Builtin Chart monitor theme subdirectories are:<br>
|
|
        <i>cpu, disk, inet, net, proc</i><br>
|
|
|
|
Builtin Meter monitor theme subdirectories are:<br>
|
|
        <i>apm, cal, clock, fs, host, mail,
|
|
mem, timer, uptime </i> <br>
|
|
The Battery monitor was originally named APM and the theme subdirectory
|
|
for it remains "apm" to avoid breaking themes.
|
|
<p>
|
|
Plugins will each have their own theme subdirectory which can be
|
|
determined from the plugin documentation.
|
|
<p>
|
|
All builtin or plugin Chart monitor theme subdirectories may have the
|
|
custom images:
|
|
<pre>
|
|
bg_chart.png
|
|
bg_grid.png
|
|
bg_panel.png
|
|
krell.png
|
|
spacer_top.png
|
|
spacer_bottom.png
|
|
</pre>
|
|
|
|
All builtin or plugin Meter monitor theme subdirectories may have the
|
|
custom images (however, not all may use the krell.png):
|
|
<pre>
|
|
bg_meter.png (bg_panel.png is accepted for convenience)
|
|
krell.png
|
|
spacer_top.png
|
|
spacer_bottom.png
|
|
</pre>
|
|
|
|
In addition to the above custom images, each builtin or plugin may
|
|
have additional images which are extension to the theme. And they
|
|
may also accept custom Style, integer, string, or image border settings
|
|
in the gkrellmrc. Plugins should document what these images and
|
|
custom settings are and how they are used. The builtin theme gkrellmrc
|
|
settings will be listed later in the gkrellmrc section, while the builtin
|
|
image extensions are listed here:
|
|

<h3>Theme Image Descriptions</h3>
|
|
<blockquote>
|
|
|
|
<h4>Background images</h4>
|
|
<ul>
|
|
<li>
|
|
frame_top.png<br>
|
|
The rendered height can be set with frame_top_height and a border
|
|
specified with frame_top_border in gkrellmrc.
|
|
Transparency is allowed.
|
|
</li>
|
|
<li>
|
|
frame_bottom.png<br>
|
|
The rendered height can be set with frame_bottom_height and a border
|
|
specified with frame_bottom_border in gkrellmrc.
|
|
Transparency is allowed.
|
|
</li>
|
|
<li>
|
|
frame_left.png<br>
|
|
The rendered width can be set with frame_left_width and a border
|
|
specified with frame_left_border in gkrellmrc.
|
|
Transparency is allowed.
|
|
</li>
|
|
<li>
|
|
frame_right.png<br>
|
|
The rendered width can be set with frame_right_width and a border
|
|
specified with frame_right_border in gkrellmrc.
|
|
Transparency is allowed.
|
|
</li>
|
|
<li>
|
|
bg_chart.png<br>
|
|
The background image for the chart area of a chart monitor.
|
|
A border for this image can be set in the gkrellmrc.
|
|
To provide custom backgrounds for specific chart monitors,
|
|
theme subdirectories may have a custom version of this image.
|
|
</li>
|
|
<li>
|
|
bg_grid.png<br>
|
|
This is a 1 or 2 pixel high image which is pasted onto a bg_chart
|
|
background image to show grid lines. Use it to get nice etched
|
|
grid lines. It should balance the requirement that it be visible
|
|
yet not distract the eye from the data that is plotted on the
|
|
chart.
|
|
Monitor subdirectories may have a custom version of this image.
|
|
</li>
|
|
<li>
|
|
bg_separator<br>
|
|
The user may optionally split Charts into data views. Data views
|
|
on a chart will be separated by this image. It will be rendered to
|
|
bg_separator_height (specified in the gkrellmrc), which should
|
|
probably be 2 pixels high.
|
|
</li>
|
|
<li>
|
|
bg_panel.png<br>
|
|
The background image for the panel area of a chart monitor.
|
|
A border for this image can be set in the gkrellmrc.
|
|
Monitor subdirectories may have a custom version of this image.
|
|
</li>
|
|
<li>
|
|
bg_meter.png<br>
|
|
The background image for the meter areas of meter monitors.
|
|
A border for this image can be set in the gkrellmrc.
|
|
Meter monitor subdirectories may have a custom version of this image
|
|
which for convenience may be named bg_panel.png.
|
|
</li>
|
|
</ul>
|
|
<h4>Detail images</h4>
|
|
|
|
The default theme images will be used for any of these which do not
|
|
exist in your theme directory.
|
|
<ul>
|
|
<li>
|
|
button_panel_out.png</li><li>
|
|
button_panel_in.png<br>
|
|
These are images for a button type where the images for it are
|
|
displayed only when the panel area where they exist has the mouse.
|
|
When this button appears, it is an overlay on a label (or decal)
|
|
to emphasize that the label has been assigned button status
|
|
for launching a command. Since the button is an overlay, it ideally
|
|
should be a 1 - 3 pixel highlighting border surrounding a transparent
|
|
interior (see the default theme implementation), but it could be a
|
|
semi-transparent special effect image depending on the theme.
|
|
If these images do not exist in your theme then the button overlay
|
|
will be constructed with a default gray color and may or may not
|
|
look good with your theme.
|
|
Set the border sizes for these images in the gkrellmrc with the
|
|
button_panel_border option.
|
|
</li>
|
|
<li>
|
|
button_meter_out.png</li><li>
|
|
button_meter_in.png<br>
|
|
Same as for button_panel except for overlay buttons in a meter area.
|
|
Set the border with the button_meter_border option in the gkrellmrc.
|
|
If your bg_meter is similar to bg_panel, then these can be copies of
|
|
the button_panel_in/out images.
|
|
</li>
|
|
<li>
|
|
krell_panel.png<br>
|
|
A vertical stack of krell frames. See the Tips and Comments below.
|
|
These are used in the bg_panel areas and are intended to be used
|
|
as fast response indicators on chart monitors. The default depth
|
|
is 4, although the middle two frames are identical. If you make
|
|
a custom krell_panel, you must tell GKrellM the depth in the
|
|
gkrellmrc file if it is different from the default.
|
|
Chart monitor subdirectories may have a custom version of this image,
|
|
which should be named krell.png
|
|
</li>
|
|
<li>
|
|
krell_meter.png<br>
|
|
A vertical stack (default depth 1) of krells used in the bg_meter
|
|
area of meter monitors. If you make a custom krell_meter, you must
|
|
tell GKrellM the depth in the gkrellmrc file if it is different
|
|
from the default.
|
|
Meter monitor subdirectories may have a custom version of this image,
|
|
which should be named krell.png
|
|
</li>
|
|
<li>
|
|
krell_slider.png<br>
|
|
A vertical stack (default depth 7) of krells used in the bg_panel
|
|
or bg_meter areas of chart or meter monitors. If you make a custom
|
|
krell_slider, you must tell GKrellM the depth in the gkrellmrc
|
|
file if it is different from the default.
|
|
</li>
|
|
<li>
|
|
decal_alarm.png<br>
|
|
A vertical stack of images that are cycled through when an alarm
|
|
is triggered. These images are usually placed behind a text decal
|
|
to highlight the value that has triggered the alarm. If you don't
|
|
have sensor voltage monitoring or the Battery monitor to play with,
|
|
run "gkrellm -demo" and you will be able to set Battery alerts and
|
|
see the decal_alarm and decal_warn in action. Set the number
|
|
of frames this image has in the gkrellmrc:<br>
|
|
      decal_alarm_frames n
|
|
</li>
|
|
<li>
|
|
decal_warn.png<br>
|
|
Same as decal_alarm.png, except it is triggered by a less serious
|
|
warning event. Set the number of frames for this image in the gkrellmrc:
|
|
      decal_warn_frames n
|
|
</li>
|
|
<li>
|
|
decal_misc.png<br>
|
|
A vertical stack of decals used for various monitors. I have tried
|
|
to make these theme generic, but you could touch them up to better
|
|
match your theme.
|
|
</li>
|
|
<li>
|
|
decal_button.png<br>
|
|
A general purpose button image which monitors may scale to different
|
|
sizes. There are two vertically stacked button image frames with the
|
|
button out image on top of the button pressed image. This image is not
|
|
used in GKrellM version 1.x.
|
|
</li>
|
|
</ul>
|
|
<h4>Optional data plotting images</h4>
|
|
<ul>
|
|
<li>
|
|
data_in.png</li><li>
|
|
data_in_grid.png</li><li>
|
|
data_out.png</li><li>
|
|
data_out_grid.png<br>
|
|
If these images exist they are used to plot data on the charts.
|
|
You can have textured or 3D plotted data to go with your bg_chart.
|
|
The data_in_grid and data_out_grid should be 1 or 2 pixel high
|
|
images and are drawn where the plotted data crosses a chart grid line.
|
|
If any of these do not exist data plotting falls back to using the
|
|
in_color and out_color specified in gkrellmrc. Any shading effect you
|
|
put into a data image should probably track shading on your bg_chart.
|
|
Shading effects are not very apparent on low data density charts,
|
|
so get a big compile or net download going to see the effects.
|
|
</li>
|
|
</ul>
|
|
|
|
<h4>Optional spacer images </h4>
|
|
<ul>
|
|
<li>
|
|
spacer_top.png</li><li>
|
|
spacer_bottom.png</li><li>
|
|
spacer_top_chart.png</li><li>
|
|
spacer_bottom_chart.png</li><li>
|
|
spacer_top_meter.png</li><li>
|
|
spacer_bottom_meter.png<br>
|
|
Spacer images form a visual separator between monitors. Spacers are
|
|
rendered to a default height of 3 pixels unless set otherwise in the
|
|
gkrellmrc. Borders for these images are set in the gkrellmrc with
|
|
spacer_top_border and spacer_bottom_border lines. Spacer images can
|
|
be set for all monitors, chart styled monitors only, meter styled only,
|
|
Theme subdirectories may have a custom version of this image.
|
|
For example, a meter monitor with two panels can be either of:
|
|
<pre>
|
|
without spacers: with spacers:
|
|
--------------------- --------------------- spacer_top
|
|
| | ---------------------
|
|
| | | | bg_meter
|
|
--------------------- ---------------------
|
|
| | | | bg_meter
|
|
| | ---------------------
|
|
--------------------- --------------------- spacer_bottom
|
|
</pre>
|
|
</li>
|
|
</ul>
|
|
|
|
<h4>Optional cap images </h4>
|
|
<ul>
|
|
<li>
|
|
cap_top_left_chart.png</li><li>
|
|
cap_bottom_left_chart.png</li><li>
|
|
cap_top_right_chart.png</li><li>
|
|
cap_bottom_right_chart.png</li><li>
|
|
cap_top_left_meter.png</li><li>
|
|
cap_bottom_left_meter.png</li><li>
|
|
cap_top_right_meter.png</li><li>
|
|
cap_bottom_right_meter.png<br>
|
|
Cap images are drawn on the left and right frames aligned to the
|
|
top and bottom of each monitor. Left cap images are left adjusted
|
|
in the left frame and right cap images are right adjusted in the right
|
|
frame. They can be turned off for specific monitors. Meter monitors
|
|
can be a single panel so it's probably difficult to design a theme with
|
|
both top and bottom meter cap images. These images are not scaled.
|
|
</li>
|
|
</ul>
|
|
|
|
<h4>Builtin monitor custom images</h4>
|
|
<ul>
|
|
<li>
|
|
cpu/nice.png</li><li>
|
|
cpu/nice_grid.png<br>
|
|
Used to plot the cpu nice time data in a color different from either
|
|
the data_in or data_out colors. If these images don't exist and the
|
|
cpu_nice_color and cpu_nice_grid_color strings are not
|
|
set in the gkrellmrc, cpu nice time will use the data_in color.
|
|
</li><li>
|
|
mail/krell_penguin.png<br>
|
|
This is the multi frame penguin animation for new mail notification.
|
|
However, it does not have to be a penguin - any alternative will do.
|
|
Frame 0 is displayed when there is no new mail to announce and so
|
|
should be left blank. When the penguin animation is enabled, new
|
|
mail to announce triggers the display of frames 1 through depth-2
|
|
as an animation moving across the width of the mail monitor panel.
|
|
Since frame depth-1 is not fully visible, it is not displayed and
|
|
is left blank. The depth must be specified in the gkrellmrc:

mail/decal_mail.png<br>
|
|
This is the stationary envelope animation in the mailcheck panel.
|
|
If envelope animation is enabled, frame 1 is shown by default and
|
|
a new mail count increase triggers frames 1 through depth-1 to be
|
|
shown as an animation.
|
|
If envelope animation is disabled, frame 1 is shown by default and
|
|
frame 0 is shown when a new mail count increase is detected.
|
|
This image is applied by default to all themes.

mem/krell_buffers.png<br>
|
|
An extra krell in the mem panel which shows kernel buffers usage. It

|
should probably be de-emphasized with respect to the main panel krell.
|
|
Offset and depth parameters for it can be set in the gkrellmrc

<pre>
|
|
rx_off, rx_on, tx_off, tx_on
|
|
</pre>
|
|
The net LEDs are stenciled onto the bg_panel backgrounds of Net
|
|
chart monitors. They may have non rectangular shapes with
|
|
transparency. The rx and tx LEDs may overlap in complex ways
|

timer/bg_timer.png<br>
|
|
This is a background for the timer part of the TimerButton meter
|

monitor and is superimposed on top of its bg_meter.
|
|
It can be used to highlight the timer and visually separate it
|
|
from the button. A border can be set for it in the gkrellmrc:
|

sensors/bg_volt.png<br>
|
|
A framing background for the voltage values of the voltage sensor
|

monitor. Run "gkrellm -demo" using the default theme to see it if
|
|
you don't have hardware sensor monitoring. You can also set a border
|
|
for this image in the gkrellmrc:
|
|
<pre>
|
|
set_image_border sensors_bg_volt l,r,t,b
|
|
</pre>
|
|
Probably the top and bottom border should be only 1 or 2.

<h3>Notes on making a GKrellM theme</h3>
|
|
<blockquote>
|
|
<ol>
|
|
<li>
|
|
A theme directory can exist anywhere for development purposes and can be
|
|
specified on the command line:
|
|
<pre>
|
|
gkrellm -t theme_dir
|
|
</pre>
|
|
Hit the F5 key to reload a theme as you make changes.
|
|
</li><li>
|
|
Detail images are drawn on bg_panel or bg_meter backgrounds as
|
|
layers and each image may have transparency.
|
|
</li><li>
|
|
Krells have several style parameters which you can set in the gkrellmrc.
|
|
But note: it is possible for a plugin coder to write code such that his
|
|
krell will not honor these settings.
|
|
<ul>
|
|
<li>
|
|
krell_yoff<br>
|
|
Adjusts a krell's vertical offset into a panel or meter area.
|
|
</li><li>
|
|
krell_depth<br>
|
|
To build a krell with depth, vertically stack krell images
|
|
in a krell_panel or krell_meter image and specify the number of frames
|
|
in a krell_depth line in the gkrellmrc. The frame displayed will
|
|
be a function of the depth and horizontal x position of the krell:
|
|
<pre>
|
|
Depth 1: One frame displayed at all positions.
|
|
2: Display frame 0 at x = 0, frame 1 at all other positions.
|
|
n > 2: Display frame 0 at x = 0, frame n-1 at x = full_scale, and
|
|
remaining frames at positions proportional to x/full_scale.
|
|
</pre>
|
|
</li><li>
|
|
krell_x_hot<br>
|
|
This is an offset in pixels from the left edge of a krell image.
|
|
Krell images are drawn so that the krell x_hot spot is drawn at the
|
|
current krell position in a panel or meter area (except for bar-mode
|
|
krells, see below).
|
|
</li><li>
|
|
krell_left_margin & krell_right_margin<br>
|
|
The range of krell motion across a panel width may be constrained
|
|
between a left and right margin where the margins are number of pixels
|
|
from the left or right panel edge respectively. These style setings are
|
|
new in GKrellM version 1.2.9.
|
|
</li><li>
|
|
krell_expand<br>
|
|
The default is for a krell to be drawn at the same size
|
|
as its original image. But, if a krell_expand value is set, the krell
|
|
width will be rendered to match the width of the GKrellM window.
|
|
The krell_expand values are:
|
|
<ul>
|
|
<li>left<br>
|
|
The krell image area from the left edge to the x_hot spot is
|
|
rendered to fit the GKrellM monitor width. Look at the
|
|
GKrellMSS plugin's VU meter krells for examples of this krell type.
|
|
</li><li>
|
|
right<br>
|
|
The krell image area from the x_hot spot to the right edge is
|
|
rendered to fit the GKrellM monitor width. This may not be useful.
|
|
</li><li>
|
|
bar-mode<br>
|
|
The total krell image width is rendered to fit the GKrellM
|
|
monitor width. Additionally, the krell x_hot spot is ignored.
|
|
Instead, the krell position is indicated by drawing only the portion
|
|
of the rendered krell image from its left edge to the current
|
|
krell position. The visual appearance is then a static "bar"
|
|
across the panel width with only the left portion up to
|
|
the current krell position visible. This is new in version 1.2.5.
|
|
</li><li>
|
|
left-scaled, right-scaled, bar-mode-scaled<br>
|
|
Same as above except the rendering of the krell width is scaled
|
|
to fit the width between the krell left and right margins. If both
|
|
krell_left_margin and krell_right_margin are zero, these modes are
|
|
equivalent to left, right, and bar-mode respectively. These are
|
|
new in version 1.2.9
|
|
</li><li>
|
|
To sumarize the difference between a bar-mode and left expanded krell:<br>
|
|
The bar-mode krell position is fixed on a panel and only a
|
|
fractional part of its width is drawn. The draw is from the krell
|
|
left margin to a right position between the left and right margins
|
|
that corresponds to the current krell value.
|
|
The left expanded krell position is moved so its x_hot spot is
|
|
placed on a panel at a position corresponding to its current krell
|
|
value. The entire krell width is drawn but will be clipped at the
|
|
krell left and right margins.
|
|
</li>
|
|
</ul>
|
|
</ul>
|
|
<li>Run "gkrellm -demo" to see some less frequently used features you may
|
|
not have available or enabled, such as cpu temps or the battery monitor.

</li>

</ol>

<h3>Theme Alternatives</h3>
|
|
<blockquote>
|
|
|
|
If there is a line in your gkrellmrc:
|
|
<pre>
|
|
theme_alternatives = N
|
|
</pre>
|
|
then you can have 1 to N different gkrellmrc and image alternatives
|
|
that can be selected in the Themes tab. For each alternative N,
|
|
you can have an optional gkrellmrc_N whose options will override any
|
|
set in the base level gkrellmrc. If any image_N.png exists, it will
|
|
be used in place of the base image.png. This can be used to give
|
|
some flexibility to your theme. You could have more than one frame
|
|
style or different font colors and sizes. For example if you have
|
|
<pre>
|
|
theme_alternatives = 2
|
|
</pre>
|
|
Then you would have 3 gkrellmrc files:
|
|
<pre>
|
|
gkrellmrc (always applied)
|
|
gkrellmrc_1 (applied after gkrellmrc for theme alternative 1)
|
|
gkrellmrc_2 (applied after gkrellmrc for theme alternative 2)
|
|
</pre>
|
|
And you can have alternative images selectively applied depending on
|
|
the alternative selected. If you had these images:
|
|
<pre>
|
|
bg_meter.png
|
|
krell.png
|
|
krell_1.png
|
|
fs/krell.png
|
|
fs/bg_meter_2.png
|
|
</pre>
|
|
then, these images would be used:
|
|
<pre>
|
|
Default Alternative 0:
|
|
Base images: bg_meter krell fs monitor images: fs/krell bg_meter
|
|
Alternative 1:
|
|
Base images: bg_meter krell_1 fs monitor images: fs/krell bg_meter
|
|
Alternative 2:
|
|
Base images: bg_meter krell fs monitor images: fs/krell fs/bg_meter_2
|
|
</pre>
|
|
</blockquote>
|
|
|
|
|
|
<h3>The gkrellmrc file</h3>
|
|
<blockquote>
|
|
|
|
Adjustments to label positions, margins, label colors/fonts, image borders,
|
|
krell parameters, frame rendering, etc are made in the gkrellmrc file.
|
|
Setting these values may have a variable effect on different monitors
|
|
because the programmer may use the values to differing degrees. For
|
|
example, margins may affect a label or some text decal but not affect
|
|
other text decals because the programmer explicitely centers the decal.
|
|
<p>
|
|
The possible gkrellmrc lines are listed here.
|
|
<p>
|
|
The author line credits the theme maker. This will appear in the Themes
|
|
configuration window.
|
|
<pre>
|
|
author = "yourname email address"
|
|
</pre>
|
|
Theme alternatives are possible, see above.
|
|
<pre>
|
|
theme_alternatives = N
|
|
</pre>
|
|
|
|
If allow_scaling is true, then net LED position and size is scaled according
|
|
to the chart_width/chart_width_ref ratio. chart_width_ref is the width
|
|
you use for designing images and placing LEDs.
|
|
<pre>
|
|
chart_width_ref = w
|
|
allow_scaling = {true | false}
|
|
</pre>
|
|
|
|
<h4>Frames</h4>
|
|
Frames can be rendered to heights and widths different from the
|
|
drawn image sizes. 0 means use the drawn image width or height.
|
|
<pre>
|
|
frame_top_height = h
|
|
frame_bottom_height = h
|
|
frame_left_width = w
|
|
frame_right_width = w
|
|
</pre>
|
|
|
|
Regions of the bg_chart, bg_panel, or bg_meter images may be overlapped onto
|
|
the left and right frames. A simple use would be to overlap some bg_chart
|
|
pixels so a chart can have a surrounding bevel outside of the active chart
|
|
drawing area. This would be used in conjunction with giving the chart a
|
|
top and bottom margin (with StyleChart *.margins) since a top and bottom chart
|
|
margin is converted to a spacer that is also outside the active drawing area.
|
|
The panel overlap values are used for bg_panel, bg_meter, space_top, and
|
|
spacer_bottom images. These are new in GKrellM version 2.1.0 and 1.3.0.
|
|
<pre>
|
|
frame_left_chart_overlap = n
|
|
frame_right_chart_overlap = n
|
|
frame_left_panel_overlap = n
|
|
frame_right_panel_overlap = n
|
|
</pre>
|
|
|
|
Spacers can also overlap the left and right frames. The overlap values
|
|
are applied to all spacers, but overlapping can be turned off for
|
|
specific monitors. These are new in GKrellM version 2.1.0 and 1.3.0.
|
|
<pre>
|
|
frame_left_spacer_overlap = l
|
|
frame_right_spacer_overlap = r
|
|
spacer_overlap_off monitor-name
|
|
</pre>
|
|
|
|
Cap images drawn in the left and right frames can be turned off for
|
|
specific monitors. This is new in GKrellM version 2.1.0 and 1.3.0.
|
|
<pre>
|
|
cap_images_off monitor-name
|
|
</pre>
|
|
|
|
<h4>Borders</h4>
|
|
|
|
Borders for images are specified with comma separated numbers in the order:<br>
|
|
      <i>left border, right border, top border, bottom border</i>
|
|
<p>
|
|
Borders for the main GKrellM window frame images.
|
|
<pre>
|
|
frame_top_border = l,r,t,b
|
|
frame_bottom_border = l,r,t,b
|
|
frame_left_border = l,r,t,b
|
|
frame_right_border = l,r,t,b
|
|
</pre>
|
|
Borders for the spacer images. Only the left and right values are used.
|
|
These are new in GKrellM version 2.1.0 and 1.3.0.
|
|
<pre>
|
|
spacer_top_border = l,r,x,x
|
|
spacer_bottom_border = l,r,x,x
|
|
</pre>
|
|
Borders for the frame overlap areas. Only the top and bottom values are used.
|
|
These are new in GKrellM version 2.1.0 and 1.3.0.
|
|
<pre>
|
|
frame_left_chart_border = x,x,t,b
|
|
frame_right_chart_border = x,x,t,b
|
|
frame_left_panel_border = x,x,t,b
|
|
frame_right_panel_border = x,x,t,b
|
|
</pre>
|
|
|
|
<h4>Chart data colors</h4>
|
|
The data colors plotted on the charts are plotted in two different ways.
|
|
If the images data_in.xxx, data_in_grid.xxx, data_out.xxx, and
|
|
data_out_grid.xxx exist in the theme dir, they are used to plot data.
|
|
If they do not exist, then the colors set here are used.
|
|
Grid colors are drawn where the plotted data crosses a grid line.
|
|
This allows grid lines to "show through" on high density charts.
|
|
Colors are hex triplets ( #rrggbb ) or rgb.txt color names. Put quotes
|
|
around two word rgb_color_names.
|
|
<pre>
|
|
chart_in_color = { #rrggbb | rgb_color_name }
|
|
chart_in_color_grid = { #rrggbb | rgb_color_name }
|
|
chart_out_color = { #rrggbb | rgb_color_name }
|
|
chart_out_color_grid = { #rrggbb | rgb_color_name }
|
|
</pre>
|
|
|
|
<h4>Chart view and grid</h4>
|
|
The height of the bg_separator image that separates chart data views.
|
|
<pre>
|
|
bg_separator_height = 2
|
|
</pre>
|
|
|
|
Some tweaking on drawing the background grid lines. 0 is normal and 1
|
|
inhibits grid line drawing at the top and bottom of charts.
|
|
This is useful for bg_chart pixmaps that have 3D shading at the top and
|
|
bottom and is a cosmetic effect.
|
|
<pre>
|
|
bg_grid_mode = {0,1}
|
|
</pre>
|
|
|
|
The default is to fill chart text rectangle extents with the chart
|
|
background so the text will be more readable on top of data. Set this
|
|
to draw chart text without first filling (this will also prevent chart
|
|
text caching so there will be slightly increased CPU usage.
|
|
<pre>
|
|
chart_text_no_fill = {true,false}
|
|
</pre>
|
|
|
|
<h4>Net monitor LEDS</h4>
|
|
Negative x values here mean justify |x| pixels from right frame.
|
|
Positive x values mean justify x pixels from left frame.
|
|
Where to put the LEDs of each net interface monitor in its panel:
|
|
<pre>
|
|
rx_led_x = x
|
|
rx_led_y = y
|
|
tx_led_x = -x
|
|
tx_led_y = y
|
|
</pre>
|
|
|
|
<h4>Animated mail decal</h4>
|
|
Number of frames in the stationary animated mail decal. Delay is
|
|
number of update ticks between each frame. Set these if you replace
|
|
the default mail decal envelope animation.
|
|
<pre>
|
|
decal_mail_frames = 18
|
|
decal_mail_delay = 1
|
|
</pre>
|
|
|
|
<h4>Alert decals</h4>
|
|
Number of frames in the alarm and warn decal animation. Set these if you
|
|
have custom decal_alarm.png or decal_warn.png images.
|
|
<pre>
|
|
decal_alarm_frames = 10
|
|
decal_warn_frames = 10
|
|
</pre>
|
|
|
|
<h4>Slider krell</h4>
|
|
There is a krell image used as a slider control. Set its depth and x_hot
|
|
if you replace the default. You can have a bar mode krell slider if you
|
|
set krell_slider_expand to "bar-mode" (for this depth should be 1).
|
|
There is one slider krell for all meter areas and panel areas, so
|
|
positioning style settings can be applied only if a monitor has programmed
|
|
the ability and this would be documented elsewhere.
|
|
<pre>
|
|
krell_slider_depth = d
|
|
krell_slider_x_hot = x
|
|
krell_slider_expand = {left | right | bar-mode} # New in 1.2.5
|
|
</pre>
|
|
|
|
<h4>Panel buttons</h4>
|
|
Borders for the panel and meter buttons.
|
|
<pre>
|
|
button_panel_border = l,r,t,b
|
|
button_meter_border = l,r,t,b
|
|
</pre>
|
|
|
|
<h4>Fonts</h4>
|
|
In gkrellm versions prior to 2.2.0 default fonts could be set in the gkrellmrc,
|
|
but this is no longer recognized and users will just config their
|
|
own font preferences if they don't like the built in default.
|
|
|
|
|
|
<h4>Spacer height</h4>
|
|
If you use any top or bottom spacer images for monitors you can set something
|
|
other than the default 3 pixel height.
|
|
The height of the spacers may be set for all monitors, or independently
|
|
for chart and meter monitor types, or specifically for individual monitors.
|
|
"mon" is a chart or meter monitor
|
|
style name as listed below for styles (eg, clock, fs, gkrellmms, etc).
|
|
|
|
<pre>
|
|
spacer_top_height = h # set for all monitors
|
|
spacer_bottom_height = h
|
|
|
|
spacer_top_height_chart = h # set for chart type monitors
|
|
spacer_bottom_height_chart = h
|
|
|
|
spacer_top_height_meter = h # set for meter type monitors
|
|
spacer_bottom_height_meter = h
|
|
|
|
spacer_top_height mon = h # set only for monitor "mon"
|
|
spacer_bottom_height mon = h
|
|
</pre>
|
|
|
|
<h4>Extension hooks</h4>
|
|
These are ways to get options set for image or feature extensions which
|
|
plugins will use. Builtins may also use these hooks to set parameters.
|
|
<p>
|
|
If a monitor uses a background image in addition to the standard bg_panel
|
|
or bg_chart and its code allows for the image to be themed,
|
|
a hook to set the border for that image may have been provided.
|
|
It will be necessary to check plugin documentation to find the names, but for
|
|
example, say a plugin "frump" uses an additional background image
|
|
"bg_special.png" and for setting its border has added an image border
|
|
hook "frump_bg_special". Then if you have made a theme image
|
|
frump/bg_special.png for this plugin, you can set the image border with:
|
|
<pre>
|
|
set_image_border frump_bg_special = l,r,t,b
|
|
</pre>
|
|
|
|
Plugins also have a way to request integer or string initialization
|
|
values from the gkrellmrc. Again, check for plugin Theme file documentation.
|
|
There could be options like:
|
|
<pre>
|
|
set_integer frump_some_integer = n
|
|
set_string frump_some_color_string = "deep sky blue"
|
|
</pre>
|
|
|
|
New in version 1.2.9, monitors may also define custom styles by adding
|
|
a custom style name field to the StyleMeter or StylePanel lines. These are
|
|
probably most useful when a monitor has additional krells. If these exist
|
|
they should be documented in a plugin's Themes or README file. For example,
|
|
if the frump plugin has a standard default krell and one extension krell
|
|
which the plugin writer has named "gas-gauge", then the gkrellmrc can first
|
|
set values for the standard krell:
|
|
<pre>
|
|
StyleMeter frump.krell_depth = 5
|
|
StyleMeter frump.krell_yoff = 2
|
|
StyleMeter frump.krell_expand = bar-mode-scaled
|
|
</pre>
|
|
|
|
The extension gas-gauge krell will use plugin defaults if you do not set
|
|
any of its style values. But when you set its first style value, it will
|
|
be initialized to the currently set standard krell values. So you only
|
|
need to specify values that are different from the standard krell, eg:
|
|
<pre>
|
|
StyleMeter frump.gas-gauge.krell_yoff = 10
|
|
StyleMeter frump.gas-gauge.krell_expand = none
|
|
</pre>
|
|
|
|
*Note: if you theme a plugin, it is a good idea to include all of its themable
|
|
parameters in your gkrellmrc in case the plugin's default values change and
|
|
break your theme. Do not rely on the default values.

<h4>Builtin monitor extension hooks</h4>
|
|
CPU monitor nice data color (both must be set and they won't be recognized
|
|
if there are theme cpu/nice.png images):
|
|
<pre>
|
|
set_string cpu_nice_color color_string
|
|
set_string cpu_nice_grid_color color_string
|
|
</pre>
|
|
|
|
Net timer monitor border for the optional bg_timer.png image. If bg_timer.png
|
|
exists, it will be placed inside the top margin and bottom margin and at
|
|
the left margin of the timer panel. The timer display will be placed
|
|
inside of the borders.
|
|
<pre>
|
|
set_image_border timer_bg_timer 1,1,2,2
|
|
</pre>
|
|
|
|
Memory monitor krell_buffers optional image:
|
|
<pre>
|
|
set_integer mem_krell_buffers_yoff 0
|
|
set_integer mem_krell_buffers_depth 1
|
|
set_integer mem_krell_buffers_x_hot -1
|
|
set_string mem_krell_buffers_expand none # New in 1.2.5
|
|
</pre>
|
|
Memory monitor krell_cache optional image:
|
|
<pre>
|
|
set_integer mem_krell_cache_yoff 0
|
|
set_integer mem_krell_cache_depth 1
|
|
set_integer mem_krell_cache_x_hot -1
|
|
set_string mem_krell_cache_expand none # New in 1.2.5
|
|
</pre>
|
|
|
|
|
|
<h4>Style settings for the monitors</h4>
|
|
Some options can be set to apply globally to areas of all similar monitors,
|
|
or can be set to individually apply only to an area of a specific monitor.
|
|
This is done with Style lines which can have a global '*' scope name or a
|
|
specific monitor name. Since these theme specifications begin at
|
|
the monitor drawing area level, there are Style lines for each area.
|
|
There are StyleChart and StylePanel lines for the chart and panel
|
|
areas in the Chart monitors, and a StyleMeter line for the
|
|
meter areas in the Meter monitors.
|
|
<p>
|
|
The builtin Chart monitors are: <i>cpu, proc, disk, inet, net</i>.<br>
|
|
To apply a setting to a particular monitor, replace the '*' with
|
|
the monitor name. Plugin Chart monitor style names may be available
|
|
which can also be used in place of the '*'.
|
|
<p>
|
|
The builtin Meter monitors are: <i>apm, cal, clock, fs, host, mail, mem,
|
|
swap, timer, sensors, uptime.</i><br>
|
|
Where for backward compatibility, "apm" is used for the Battery monitor.
|
|
To apply a setting to a particular monitor, replace the '*' with
|
|
the monitor name. Plugin Meter monitor style names may be available
|
|
which can also be used in place of the '*'.
|
|
<p>
|
|
Notes about Style settings for chart, panel, and meter areas:
|
|
<ul>
|
|
<li>textcolor line settings are:
|
|
<pre>
|
|
color shadow_color drawing_effect
|
|
</pre>
|
|
color or shadow_color may be hex #rrggbb or text rgb_color_names, with
|
|
two word rgb_color_names enclosed in quotes.
|
|
</li><li>
|
|
transparency settings are:
|
|
<ul><li> 1 - Forces a totally transparent chart, panel, or meter area.</li>
|
|
<li>2 - For a partially transparent chart, panel, or meter area.</li>
|
|
</ul>
|
|
</li><li>
|
|
For charts only: if top and bottom margins are set, the margin regions
|
|
are converted to spacers and are excluded from the active drawing area.
|
|
</li>
|
|
</ul>
|
|
<p>
|
|
Notes about Style settings for panel or meter areas only:
|
|
<ul>
|
|
<li>label_position is a percent of chart width, so a position of 50
|
|
would horizontally center a label.
|
|
</li><li>
|
|
<li>label_yoff (new in 2.2.2) is a pixel offset for labels from the top of
|
|
a panel. If label_yoff is <= 0 (the default), labels are placed at the
|
|
panel top margin. Use this if for some reason you want to control a
|
|
label's y postion independent of the panel top margin setting.
|
|
Not all panels use labels, so this may be of special case usefulness.
|
|
</li><li>
|
|
margins may be used to set all margins at once, or you may individually
|
|
set left_margin, right_margin, top_margin, bottom_margin. They are used
|
|
for positioning of labels and decal. margins, left_margin, and
|
|
right_margin are new in 1.2.9. The old "margin" (no 's') which sets
|
|
both left and right margin to the same value may still be used.
|
|
Krell margins are set independently of panel margins with
|
|
krell_left_margin and krell_right_margin. Krell vertical positioning
|
|
uses krell_yoff and there are no top or bottom krell margins.
|
|
</li><li>
|
|
krell_depth is the number of frames in the krell image.
|
|
</li><li>
|
|
krell_x_hot is an offset into a krell frame. Set to -1 to set x_hot
|
|
to center.
|
|
</li><li>
|
|
krell_yoff is an offset from a panel or meter area top for krell
|
|
drawing.
|
|
</li><li>
|
|
scroll_text_cache_off is a boolean that will prevent use of a scroll text
|
|
decal pixmap for scrolling. Set this to "yes" if the background
|
|
of scrolling text does not blend well with your panel background on
|
|
monitors such as host, fs, mem, and swap.
|
|
This is new for version
|
|
2.2.0 and keep in mind there can be an increased CPU usage tradeoff
|
|
when this is set. Various plugins will probably be updated to use
|
|
scrolling text decals.
|
|
</li><li>A theme can assume the <i>large_font, normal_font, small_font</i>
|
|
strings used in font settings will be relatively sized as implied
|
|
by their names even though a user is free to select any font
|
|
he likes for each.
|
|
