<h3>Changelog for GKrellM Plugins</h3>
|
|
<hr size="4">
|
|
|
|
<h4>Changes for versions 2.3.1 - 2.3.2</h4>
|
|
none
|
|
|
|
<h4>Changes for version 2.3.0</h4>
|
|
New functions so plugins can export labels to display on charts and panels.
|
|
A plugin can request or cancel exporting with these two:
|
|
<pre>
|
|
gint gkrellm_plugin_export_label(GkrellmMonitor *mon_plugin,
|
|
gchar *mon_name,
|
|
gchar key, gchar *(*func)(gchar key, gchar *which));
|
|
void gkrellm_plugin_cancel_label(GkrellmMonitor *mon_plugin, gint id);
|
|
</pre>
|
|
Monitors must be updated to call this to get a plugin's label (currently
|
|
net monitor only).
|
|
<pre>
|
|
gchar *gkrellm_plugin_get_exported_label(GkrellmMonitor *mon,
|
|
gchar key, gchar *which);
|
|
</pre>
|
|
For an example of these, I've patched GKrellM2-show_ip to export its ip
|
|
address string for a net interface to the builtin Net monitor. With the
|
|
plugin enabled, you can enter a "$A" variable in the Net monitor
|
|
"Format String for Chart Labels" to diplay an IP address returned
|
|
from GKrellM2-show_ip.
|
|
<p>
|
|
For gkrellmd server plugins:
|
|
<pre>
|
|
GkrellmdTicks *gkrellmd_ticks(void);
|
|
gint gkrellmd_get_timer_ticks(void);
|
|
</pre>
|
|
|
|
<h4>Changes for version 2.2.7 - 2.2.10</h4>
|
|
none
|
|
|
|
<h4>Changes for version 2.2.5</h4>
|
|
<ul>
|
|
<li>
|
|
gkrellmd plugins can read config from a gkrellmd.conf file. Plugin
|
|
specific config must appear like so:
|
|
<pre>
|
|
[monitor-name]
|
|
config line 0
|
|
config line 1
|
|
...
|
|
[/monitor-name]
|
|
</pre>
|
|
gkrellmd plugins can read the config lines with:
|
|
<pre>
|
|
const gchar *gkrellmd_config_getline(GkrellmdMonitor *mon);
|
|
</pre>
|
|
</li>
|
|
<li>
|
|
gkrellmd plugins can read data sent from their gkrellm client plugins
|
|
(demo5 is updated to demonstrate this) using the functions:
|
|
<pre>
|
|
gboolean gkrellm_client_send_to_server(gchar *key_name, gchar *line);
|
|
void gkrellmd_client_input_connect(GkrellmdMonitor *mon,
|
|
void (*func)(GkrellmdClient *, gchar *));
|
|
</pre>
|
|
</li>
|
|
<li>
|
|
Various other new functions (mostly to round out using text markup):
|
|
<pre>
|
|
GkrellmDecal *gkrellm_create_decal_text_markup(GkrellmPanel *p, gchar *string,
|
|
GkrellmTextstyle *ts, GkrellmStyle *style,
|
|
gint x, gint y, gint w);
|
|
void gkrellm_decal_text_markup_insert(GkrellmDecal *d, gchar *s,
|
|
GkrellmTextstyle *ts, gint x_off, gint y_off);
|
|
void gkrellm_decal_text_nth_inserted_set_offset(GkrellmDecal *d,
|
|
gint n, gint x_off, gint y_off);
|
|
void gkrellm_decal_text_nth_inserted_get_offset(GkrellmDecal *d,
|
|
gint n, gint *x_off, gint *y_off);
|
|
void gkrellm_config_instant_apply(GkrellmMonitor *mon);
|
|
GtkTreeSelection *gkrellm_gtk_scrolled_selection(GtkTreeView *treeview,
|
|
GtkWidget *box, GtkSelectionMode s_mode,
|
|
GtkPolicyType h_policy, GtkPolicyType v_policy,
|
|
void (*func_cb)(), gpointer data);
|
|
void gkrellm_text_markup_extents(PangoFontDescription *font_desc,
|
|
gchar *text, gint len, gint *width, gint *height,
|
|
gint *baseline, gint *y_ink);
|
|
gint gkrellm_gdk_string_markup_width(PangoFontDescription *, gchar *);
|
|
gint gkrellm_gdk_text_markup_width(PangoFontDescription *font_desc,
|
|
const gchar *string, gint len);
|
|
void gkrellm_gdk_draw_string_markup(GdkDrawable *drawable,
|
|
PangoFontDescription *font,
|
|
GdkGC *gc, gint x, gint y, gchar *string);
|
|
void gkrellm_gdk_draw_text_markup(GdkDrawable *drawable,
|
|
PangoFontDescription *font,
|
|
GdkGC *gc, gint x, gint y, gchar *string, gint len);
|
|
</pre>
|
|
</li>
|
|
|
|
<h4>Changes for versions 2.2.3 - 2.2.4</h4>
|
|
none
|
|
|
|
<h4>Changes for version 2.2.2</h4>
|
|
New function to get theme position settings for panel labels.
|
|
<pre>
|
|
void gkrellm_panel_label_get_position(GkrellmStyle *style,
|
|
gint *x_position, gint *y_off);
|
|
</pre>
|
|
|
|
|
|
<h4>Changes for version 2.2.1</h4>
|
|
New functions for drawing text decals using Pango markup:
|
|
<pre>
|
|
void gkrellm_draw_decal_markup(GkrellmPanel *p, GkrellmDecal *d, gchar *text);
|
|
void gkrellm_decal_scroll_text_set_markup(GkrellmPanel *p,
|
|
GkrellmDecal *d, gchar *text);
|
|
</pre>
|
|
The gkrellm_decal_scroll_text_set_text() function introduced in 2.2.0
|
|
no longer uses markup.
|
|
|
|
|
|
<h4>Changes for version 2.2.0</h4>
|
|
<ul>
|
|
<li> Gkrellm text drawing is converted from GdkFont to Pango. The
|
|
main issue here is that plugins should not be using GdkFont functions
|
|
such as gdk_string_width() and should use the gkrellm_gdk functions
|
|
listed below. With maybe only one or two exceptions, existing plugins
|
|
should compile (with some possible warnings) and run fine since
|
|
gkrellm now intercepts some straight GdkFont functions. Without this
|
|
interception, many plugins would crash gkrellm. A plugin using
|
|
gdk_string_width() can compile under all gkrellm versions by
|
|
substituting in gkrellm_gdk_string_width() and having this define:
|
|
<pre>
|
|
#if !GKRELLM_CHECK_VERSION(2,2,0)
|
|
#define gkrellm_gdk_string_width gdk_string_width
|
|
#endif
|
|
</pre>
|
|
</li>
|
|
<li> There can now be gkrellmd server plugins. See the tutorial
|
|
demo5 plugin on the plugins page at gkrellm.net.
|
|
</li>
|
|
<li>Updated the plugins reference with the new functions. Updated demo3
|
|
to use new scrolling text functions.
|
|
</li>
|
|
<li> gkrellm_draw_decal_text() now ignores the "value" arg and
|
|
internally checks for changed text before doing a redraw.
|
|
</li>
|
|
<li> gkrellm_create_decal_text_with_height() behavior is changed because
|
|
GdkFont baseline has a different definition from Pango baseline. So the
|
|
last arg to the function now has a different meaning. See the
|
|
plugin programmers reference.
|
|
</li>
|
|
</ul>
|
|
|
|

<h4>Changes for version 2.1.2 - 2.1.7</h4>
|
|
None
|
|
|
|
<h4>Changes for version 2.1.1</h4>
|
|
Users can set a theme scale. Buttons made with
|
|
gkrellm_make_scaled_button() and krells are automatically theme scaled, but
|
|
plugins that have their own multi frame
|
|
decal images will need a code change if they want the decal image to be
|
|
user scalable. This fragment shows a clean way to do it:
|
|
<pre>
|
|
gkrellm_load_piximae("foo", foo_xpm, &foo_piximage, FOO_STYLE_NAME);
|
|
#if defined(GKRELLM_HAVE_THEME_SCALE)
|
|
/* New function scales to multiple of frame height and does not require
|
|
| the plugin to maintain a pixmap and mask.
|
|
*/
|
|
foo_decal = gkrellm_make_scaled_decal_pixmap(panel, foo_piximage, style,
|
|
N_FOO_FRAMES, -1, -1, 0, 0);
|
|
#else
|
|
gkrellm_scale_piximage_to_pixmap(foo_piximage, &foo_pixmap,
|
|
&foo_mask, 0, 0);
|
|
foo_decal = gkrellm_create_decal_pixmap(p, foo_pixmap, foo_mask,
|
|
N_FOO_FRAMES, style, -1, -1);
|
|
#endif
|
|
</pre>
|
|
However, if the plugin needs to maintain the pixmap and mask, you can
|
|
handle things yourself by
|
|
scaling the decal frame height by the theme_scale value and
|
|
then creating the pixmap height to be a multiple of the frame height:
|
|
<pre>
|
|
#if defined(GKRELLM_HAVE_THEME_SCALE)
|
|
h = gdk_pixbuf_get_height(foo_piximage->pixbuf) / N_FOO_FRAMES;
|
|
h *= gkrellm_get_theme_scale(); /* New function */
|
|
h *= N_FOO_FRAMES;
|
|
w = -1; /* Scales to drawn image size * theme_scale */
|
|
#else
|
|
h = 0; /* Will scale to drawn image size */
|
|
w = 0;
|
|
#endif
|
|
gkrellm_scale_piximage_to_pixmap(foo_piximage, &foo_pixmap,
|
|
&foo_mask, w, h);
|
|
foo_decal = gkrellm_create_decal_pixmap(panel, foo_pixmap, foo_mask,
|
|
N_FOO_FRAMES, style, -1, -1);
|
|
</pre>
|
|
Code that places decals relative to margins or to other decal/krell
|
|
positions and sizes should be fine, but if you place at hardwired locations,
|
|
the x,y location values might need to be
|
|
scaled by gkrellm_get_theme_scale() for things to look right when the
|
|
user changes the theme scale.
|
|
|
|
<h4>Changes for version 2.1.0</h4>
|
|
There is an issue with the new theming features in 2.1.0. There are
|
|
only two defined monitor types (chart and meter), but some monitors
|
|
are hybrids. The new spacer and cap theme images are applied based
|
|
on monitor type, but for hybrid monitors there is no way for gkrellm
|
|
to determine which images should really be used. So there is a
|
|
new function:
|
|
<pre>
|
|
gkrellm_spacers_set_types(GkrellmMonitor *mon, gint top, gint bottom);
|
|
</pre>
|
|
where top and bottom are GKRELLM_SPACER_CHART or GKRELLM_SPACER_METER.
|
|
Hybrid monitors can now make this call to let gkrellm know what it
|
|
is doing. See the builtin mem.c and my plugin gkrellmss (version 2.1)
|
|
for examples of its usage.
|
|
|
|
<h4>Changes for version 2.0.4</h4>
|
|
None.
|
|
|
|
<h4>Changes for version 2.0.3</h4>
|
|
<ul>
|
|
<li> If a plugin implements instant apply (so no apply_config() and it
|
|
is NULL in the GkrellmMonitor struct), then if the plugins config
|
|
page is selected, there will be no "Apply" button shown since
|
|
it, ...ummm... doesn't apply.</li>
|
|
<li> For plugins which have an apply_config(), now there is an
|
|
implied apply if the user leaves the plugins config page
|
|
by selecting another monitor. </li>
|
|
</ul>
|
|
|
|
<h4>Changes for version 2.0.1 - 2.0.2</h4>
|
|
None.

|
|
|
<h4>Changes for version 2.0.0</h4>
|
|
See the gkrellm-2.0 porting guide.
|
|

|
|
<pre><font size="-1">
|
|
Style *gkrellm_meter_style_by_name(gchar *name);
|
|
Style *gkrellm_panel_style_by_name(gchar *name);
|
|
Style *gkrellm_chart_style_by_name(gchar *name);
|
|
</font></pre>
|
|
which provide for using a custom style
|
|
with values set with
|
|
StyleMeter or StylePanel lines in the gkrellmrc. If you have extra
|
|
krells you want to allow to be themed, this can clean up your code
|
|
by eliminating a bunch
|
|
of gkrellm_get_gkrellmrc_integer() or gkrellm_get_gkrellmrc_string()
|
|
calls.
|
|
See the Themes file and gkrellmss.c in GKrellMSS 0.4 (when I release it)
|
|
for a working example of this.
|
|
<p>
|
|
Style margin changes for more layout control. Usually these will be set
|
|
by a theme author in the gkrellmrc:
|
|
<ul>
|
|
<li>There is now a left and right panel margin instead of the single
|
|
"margin". These are in a new Margin struct which also includes
|
|
the top and bottom margin. Use gkrellm_get_style_margins() to
|
|
access the themed margin values.</li>
|
|
<li>The Style struct has new krell_left_margin and krell_right_margin
|
|
for setting krell margins independently of panel margins.</li>
|
|
</ul>

<h4>Changes for version 1.2.6 - 1.2.8</h4>
|
|
None.
|
|
|
|
<h4>Changes for version 1.2.5</h4>
|
|
Added some functions.
|
|
<pre><font size="-1">
|
|
void gkrellm_set_krell_expand(Style *, gchar *);
|
|
void gkrellm_insert_krell_nth(Panel *, Krell *, gint);
|
|
void gkrellm_insert_decal_nth(Panel *, Decal *, gint);
|
|
gboolean gkrellm_in_decal(Decal *, GdkEventButton *);
|
|
void gkrellm_decal_button_connect(DecalButton *, void (*func)(), void *);
|
|
void gkrellm_decal_button_right_connect(DecalButton *, void (*func)(), void *);
|
|
void gkrellm_set_button_sensitive(DecalButton *, gboolean);
|
|
void gkrellm_hide_button(DecalButton *);
|
|
void gkrellm_show_button(DecalButton *);
|
|
</font></pre>
|
|
|
|
The DecalButton callback function prototype adds a "gpointer data" so
|
|
you don't have to reference button->data.
|
|
|
|
<h4>Changes for version 1.2.3 - 1.2.4</h4>
|
|
None.
|
|
|
|
<h4>Changes for version 1.2.2</h4>
|
|
Added some functions. Some of them are (for controlling decals and krells):
|
|
<pre><font size="-1">
|
|
void gkrellm_set_krell_margins(Panel *, Krell *k, gint, gint);
|
|
void gkrellm_move_krell_yoff(Panel *, Krell *, gint);
|
|
void gkrellm_draw_decal_on_chart(Chart *, Decal *, gint, gint);
|
|
void gkrellm_move_decal(Panel *, Decal *, gint, gint);
|
|
void gkrellm_decal_on_top_layer(Decal *, gboolean);
|
|
</font></pre>
|
|
|
|
<h4>Changes for version 1.2.1</h4>
|
|
None.
|
|
|
|
<h4>Changes for version 1.2.0</h4>
|
|
Any plugin using charts will require coding changes and a recompile.
|
|
Charts are now automatically user configurable with a right click on a chart.
|
|
There are too many new functions to cover here, so look over the updated
|
|
plugin programmers reference and especially the chart demo1.c program.
|
|
All of the "chartconfig" and "chartdata" functions are new. The create
|
|
and destroy functions are changed to gkrellm_chart_create() and
|
|
gkrellm_chart_destroy(). You should no longer do awkward settings such
|
|
as chart->previous = blah (use gkrellm_monotonic_chartdata()) or
|
|
chart->scale_max = 0 (chart scaling is now handled properly)
|
|
A couple of key points to note are:
|
|
<ul>
|
|
<li>Charts no longer automatically have two data sets. There is a new
|
|
ChartData struct which is added to Charts as needed. To handle a
|
|
variable number of data layers, the store data routine is changed
|
|
to a varargs <br>
|
|
        gkrellm_store_chartdata(Chart *, gulong total, ...);
|
|
</li>
|
|
<li>There are several chart config options all handled automatically. But
|
|
you do need to save and load the config - see demo1.c
|
|
</li>
|
|
</ul>
|
|
|
|
Plugins that use panels do not require a recompile, but I've made
|
|
the chart and panel coding styles cleaner and more consistent by adding
|
|
some functions you should migrate to. When you do,
|
|
your plugin will depend on GKrellM version >= 1.2.0.
|
|
These are for coding cleanups and some new functions:
|
|
<ul>
|
|
<li>If you have a spare right click, you can have it call<br>
|
|
        gkrellm_open_config_window(Monitor *);<br>
|
|
and the config window will be opened right to your plugin's config page.
|
|
</li>
|
|
<li>Use gkrellm_panel_create() instead of gkrellm_create_panel().
|
|
Use gkrellm_panel_configure() instead of gkrellm_configure_panel().
|
|
Use gkrellm_panel_enable_visibility() instead of
|
|
gkrellm_enable_visibility()
|
|
(or you could use gkrellm_hide_panel() and gkrellm_show_panel()).
|
|
See the plugin programmers reference for usage.
|
|
</li>
|
|
<li> After you upgrade to using these new functions, there should
|
|
be no need to worry about managing stuff that gkrellm should be
|
|
handling. ie, you should never have to make
|
|
any gkrellm_monitor_height_adjust() or gkrellm_pack_side_frame() calls.
|
|
Also, decal/krell lists will be automatically destroyed prior to
|
|
create plugin calls (but you can override this) and you should no
|
|
longer set krell->previous
|
|
(use gkrellm_monotonic_krell_values()). Also if you destroy a panel,
|
|
you will no longer need to destroy lists, adjust monitor height,
|
|
or g_free() the Panel struct storage.
|
|
<p>
|
|
Look at the revised demos in the programmers
|
|
reference. Also look at the bottom of gkrellm_public_proto.h for the
|
|
list of functions that should be replaced.

|

<blockquote>
|
|
Looking ahead a bit (some months?) when I get to 1.1.0
|
|
I want the gkrellm namespace to be cleaned up. I'm defining
|
|
that to mean that if you do a "nm -u plugin.so" the undefined symbols
|
|
expected to link to gkrellm will be only GK and gkrellm_XXX symbols.
|
|
Starting with 1.0.4 gkrellm_private_proto.h is no longer included
|
|
by gkrellm.h and it is not installed in the include directory. I
|
|
have temporarily moved some symbols affecting a few plugins
|
|
from private to public proto.h. I hope I moved enough so
|
|
that all current plugins I know of will still compile. The plan is
|
|
when 1.1.0 arrives I will do the "Cut Here" at the bottom of
|
|
gkrellm_public_proto.h, so source will need to be in sync
|
|
by then.<br>
|
|
<b>To check if you need changes,
|
|
#ifdef out the part that will be cut and see if you get warnings
|
|
compiling with -Wall.</b><br>
|
|
If you have changes to make or want to use any new functions below,
|
|
make your source dependent on version 1.0.4 as described in the
|
|
changes for version 1.0.3.
|
|
<p>
|
|
Added some handy utility routines (most were already in
|
|
gkrellm_private_proto.h without a gkrellm_ prefix):
|
|
<pre><font size="-1">
|
|
GtkWidget *gkrellm_create_tab(GtkWidget *, gchar *);
|
|
gchar *gkrellm_entry_get_text(GtkWidget **);
|
|
void gkrellm_spin_button(GtkWidget *, GtkWidget **, gfloat, gfloat, gfloat,
|
|
gfloat, gfloat, gint, gint, void (*func)(), gpointer, gboolean, gchar *);
|
|
void gkrellm_check_button(GtkWidget *, GtkWidget **, gboolean, gboolean, gint, gchar *);
|
|
gchar *gkrellm_homedir(void);
|
|
gboolean gkrellm_dup_string(gchar **, gchar *);
|
|
gchar *gkrellm_make_config_file_name(gchar *, gchar *);
|
|
struct tm *gkrellm_get_current_time();
|
|
</font></pre>
|
|
Other uninteresting changes are: Added some session manager plugin helper
|
|
functions so I could write the gkrellm-gnome plugin and exported sensor
|
|
reading functions for special purpose sensor monitoring plugins.
|

<h4>Changes for version 1.0.3</h4>
|
|
<ul>
|
|
<li> You can run <b>gkrellm -p plugin-under-test.so</b> to load the plugin
|
|
you are working on in the current directory. Should be a development
|
|
time saver.
|
|
</li>
|
|
<li>
|
|
I am changing the way top and bottom margins are specified in panels.
|
|
Previously labels and decals were margined by using the top and
|
|
bottom borders of the background image. Now there are new
|
|
<b>top_margin</b> and <b>bottom_margin</b> values in the Style struct to go
|
|
with the existing <b>margin</b> value (which is used for both
|
|
left and right margins). Most
|
|
plugins probably don't care about this since the gkrellm create and
|
|
configure routines handle most placements, but if you were using
|
|
any <b>border.top</b> or <b>border.bottom</b> references for positioning,
|
|
you should use the new routine:
|
|
<pre><font size="-1">
|
|
void gkrellm_get_top_bottom_margins(Style *s, gint *top, gint *bot)
|
|
</font></pre>
|
|
|
|
This routine determines if a theme is using the new top_margin and
|
|
bottom_margin values and returns them, otherwise it will return the old
|
|
top and bottom border values so existing themes will not break.
|
|
</li>
|
|
<p>
|
|
<li>
|
|
Two new Style copying functions needed to fix a bad programming practice
|
|
I had promoted in my demo programs:
|
|
<pre><font size="-1">
|
|
Style *gkrellm_copy_style(Style *src_style);
|
|
TextStyle *gkrellm_copy_textstyle(TextStyle *src_style);
|
|
</font></pre>
|
|
|
|
Previously I had suggested
|
|
copying a style to a plugin local style like so:
|
|
<pre><font size="-1">
|
|
Style *my_style, *style;
|
|
|
|
style = gkrellm_meter_style(DEFAULT_STYLE);
|
|
my_style = gkrellm_style_new0();
|
|
*my_style = *style;
|
|
</font></pre>
|
|
|
|
But I goofed and this is no good. If you have such code please change it.
|
|
It should now be done like so:
|
|
<pre><font size="-1">
|
|
Style *my_style, *style;
|
|
|
|
style = gkrellm_meter_style(style_id);
|
|
my_style = gkrellm_copy_style(style);
|
|
</font></pre>
|
|
|
|
<b>NOTE:</b> Just to emphasize a point, you should never have a static
|
|
local Style or TextStyle declared. You should use the above copy
|
|
function so the style can be initialized with a themes gkrellmrc settings.
|
|
</li>
|
|
<p>
|
|
<li>
|
|
If you do use the above new routines and don't want to clutter your code
|
|
with #ifdefs to make it compatible with old GKrellM versions, I suggest
|
|
making your plugin require version 1.0.3. After all, I don't think it's
|
|
unreasonable to ask someone installing your latest plugin
|
|
version to also have installed a recent GKrellM version. It's what I
|
|
would do and it can keep your code base clean. You can enforce
|
|
this requirement in your header file after you include gkrellm.h:
|
|
<pre><font size="-1">
|
|
#include <gkrellm/gkrellm.h>
|
|
#if !defined(GKRELLM_VERSION_MAJOR) \
|
|
|| (GKRELLM_VERSION_MAJOR==1 && GKRELLM_VERSION_MINOR==0 && GKRELLM_VERSION_REV<3)
|
|
#error This plugin requires GKrellM version >= 1.0.3
|
|
#endif
|
|
</font></pre>
|
|
|
|
Notice that in 1.0.3 you can now use GKRELLM_VERSION_MAJOR instead of just
|
|
VERSION_MAJOR.
|
|
Similarly, if you want to clean out ugly #ifdef'ed code sections
|
|
for previous versions of your plugin, just do it!
|
|
But if you want to conditional on a GKrellM version prior to 1.0.3, you
|
|
can't use the GKRELLM_VERSION_MAJOR.
|
|
Ie. if you #ifdef'ed in some of the new functions for 0.10.0, clean them
|
|
out and put in your header:
|
|
<pre><font size="-1">
|
|
#include <gkrellm/gkrellm.h>
|
|
#if   (VERSION_MAJOR==0) && (VERSION_MINOR<10)
|
|
#error This plugin requires GKrellM version >= 0.10.0
|
|
#endif
|
|
</font></pre>
|
|
But, if you are going to do this, why not just make a clean break?
|
|
Go ahead and use the first example using GKRELLM_VERSION_XXX defines,
|
|
and be done with it!

<h4>Changes for version 1.0.0 - 1.0.2</h4>
|
|
None.
|
|
|
|
<h4>Changes for version 0.10.5</h4>

Added these routines:
|

<ul>
|
|
<li>gkrellm_config_modified()</li>
|
|
<li>gkrellm_chart_images_override()</li>
|

<h4>Changes for version 0.10.2 - 0.10.4</h4>
|
|
None.
|
|
|
|
<h4>Changes for version 0.10.1</h4>
|
|
<ul>
|
|
<li>There has been a loose end with controlling plugin placement when
|
|
multiple plugins are placing themselves before the same monitor. So far
|
|
this placement has been determined by the order plugins are read from the
|
|
plugin directories and this in turn is a function of the order they
|
|
were written into the directory. There is no alphabetical sorting
|
|
at all. So to give some control, plugins can now specify a gravity value
|
|
from 0 to 15 in the placement parameter. Think of it as higher gravity
|
|
pulling a plugin down in its placement slot. If you see no reason your
|
|
plugin should care about this level of control then do nothing, no
|
|
code changes are required. But if there is some reason you prefer your
|
|
plugin be biased downwards, then give it gravity like so:
|
|
<pre>
|
|
#ifdef GRAVITY
|
|
#define MY_PLACEMENT (MON_APM | GRAVITY(8))
|
|
#else
|
|
#define MY_PLACEMENT (MON_APM)
|
|
#endif
|
|
</pre>
|
|
If there is a very strong reason to bias it down, give it gravity 15.
|
|
If you want placement with respect to another plugin that has gravity,
|
|
then give yours a gravity value just above or below the gravity for the
|
|
other plugin. Many plugins can just pass this by and be fine with the
|
|
default zero gravity.
|
|
<p>
|
|
<li>Cleaned out all GK.debug usage from GKrellM source so it is now solely for
|
|
plugin use. You can run "gkrellm -debug" or "gkrellm -debugN" where N is
|
|
an arbitrary integer you pick for your plugin specific use. Basically,
|
|
use "if (GK.debug)" for general debugging, or use "if (GK.debug == N)"
|
|
for debugging isolated to your plugin. I guess just rely on chance
|
|
and squatters rights and just pick an N that
|
|
you hope does not collide with some other plugin.
|
|
</ul>

<h4>Changes for version 0.10.0</h4>
|
|
<blockquote>
|
|
Final release check list (some details are below):
|
|
<ul>
|
|
<li>Fix GK struct references - only xxx_tick and debug references are OK.
|
|
<li>Consider adding style_id support - use the new functions.
|
|
<li>Consider using gkrellm_load_image() to load custom #included images.
|
|
</ul>
|
|
|
|
<h5>Details</h5>
|
|
New functions (see plugin programmers reference):
|
|
<pre><font size="-1">
|
|
gboolean gkrellm_load_image(gchar *name, gchar **xpm, GdkImlibImage **im, gchar *subdir);
|
|
gboolean gkrellm_set_image_border(gchar *name, gchar **xpm, Style *style);
|
|
gint gkrellm_add_chart_style(Monitor *mon, gchar *name);
|
|
gint gkrellm_add_meter_style(Monitor *mon, gchar *name);
|
|
gint gkrellm_lookup_chart_style_id(gchar *name);
|
|
gint gkrellm_lookup_meter_style_id(gchar *name);
|
|
gchar *gkrellm_get_theme_path(void);
|
|
void gkrellm_add_info_text_string(GtkWidget *text, gchar *string);
|
|
</font></pre>
|
|
|
|
The GK structure is changing.
|
|
It has always been the case that the only safe parts of GK to
|
|
access are the debug and xxx_tick parts.
|
|
If any plugin directly accesses the structure (does not use the
|
|
gkrellm_XXX() helper functions) for image or style pointers
|
|
it's pretty certain it will break.
|
|
Also, even if you did use gkrellm_XXX() functions to access images or styles
|
|
for other monitors (not the DEFAULT_STYLE) you will now get unexpected
|
|
results (but should not crash). Use the gkrellm_lookup_xxxx_style_id()
|
|
functions to get a style_id for other monitors.
|
|
Some other references are OK for now,
|
|
like GK.theme_path, but should be changed to the new gkrellm_get_theme_path()
|
|
under 0.10.0 (but consider using the new gkrellm_load_image() function
|
|
so you don't have to do any theme path processing at all).
|
|
<p>
|
|
Code references like these are a problem:
|
|
<pre>
|
|
GK.XXX_style[id] where XXX is chart, panel, or meter.
|
|
GK.bg_XXX_image[id] where XXX is chart, panel, meter, or grid.
|
|
GK.krell_XXX_image[] where XXX is panel or meter
|
|
GK.monitor_height += p->h;
|
|
UC.chart_width
|
|
GK.decal_misc_pixmap
|
|
some_function(XXX_STYLE) where XXX is APM, FS, CLOCK, CAL, etc.
|
|
</pre>
|
|
Fix them like this:
|
|
<pre>
|
|
gkrellm_XXX_style(id);
|
|
gkrellm_bg_XXX_image(id);
|
|
gkrellm_krell_XXX_image(id);
|
|
gkrellm_monitor_height_adjust(h);
|
|
gkrellm_chart_width();
|
|
gkrellm_decal_misc_pixmap();
|
|
some_function(gkrellm_lookup_meter_style_id(XXX_STYLE_NAME));
|
|
</pre>
|
|
See the plugin programmers reference. It has updated documentation on the
|
|
above new calls and the demo programs are updated as well. The
|
|
short story is plugins can
|
|
now be themed at the same level as builtins. Check the Styles and Themes
|
|
section.
|
|
<p>
|
|
Here's something that might help:
|
|
<ul>
|
|
<li>Make your plugin compilable under 0.9.x or 0.10.x by doing this:<br>
|
|
In a header or at the top of your source file:
|
|
<pre>
|
|
#if ((VERSION_MAJOR>0)||(VERSION_MINOR>9))
|
|
#define PLUGIN_STYLE style_id
|
|
static gint style_id;
|
|
#else
|
|
#define PLUGIN_STYLE DEFAULT_STYLE
|
|
#endif
|
|
</pre>
|
|
Access styles and images by using PLUGIN_STYLE as an argument.
|
|
And in the init_plugin() routine, add this:
|
|
<pre>
|
|
#if ((VERSION_MAJOR>0)||(VERSION_MINOR>9))
|
|
style_id = gkrellm_add_meter_style(&plugin_mon, "somename");
|
|
#endif
|
|
</pre>
|
|
<li>If you have custom images to load and want to use gkrellm_load_image(),
|
|
it is more difficult to be compilable under 0.9.x and 0.10.x. You
|
|
could use #if around gkrellm_load_image() calls, or you could just
|
|
not bother and have the requirement that the plugin needs 0.10.x.

<h4>Changes for version 0.9.9</h4>

<blockquote>
|
|
Not much new for this release. About the only thing is I have followed
|
|
the lead of several plugins and added a global function to get the nice
|
|
bold (and added italic) text into the Info/Help pages. You can use it if
|
|
you want or keep doing it the way you have been, but one benefit is
|
|
that I have an alternate larger font size the user can select if he
|
|
wants. Just insert <b> for bold or <i> for
|
|
bold italic in front of
|
|
strings in a string array, like this:
|
|
<pre><font size="-1">
|
|
gchar *info_text[] =
|
|
{
|
|
"<b>The first ",
|
|
"two words of this line are bold\n"

"and the last two words of this line ",

"<i>are italic\n"

If you look at the GKrellM source you will notice _( ) and N_( ) macros
|
|
around text strings. There has been some interest in internationalizing
|
|
the program (Turbolinux Japan) and these macros support that. I don't
|
|
know if this will extend to the plugins, so my suggestion is do whatever
|
|
you feel comfortable with (the macros are a no-op unless i18n is enabled).
|
|
If you choose to do this, then the above info_text declaration would look like:
|
|
|
|
|
|
<pre><font size="-1">
|
|
gchar *info_text[] =
|
|
{
|
|
N_("<b>The first "),
|
|
N_("two words of this line are bold\n"
|
|
"and the last two words of this line "),
|
|
N_("<i>are italic\n")
|
|
};
|
|
</font></pre>
|
|
|
|
|
|
I'm giving some thought to a way for plugins to have custom theme images
|
|
(as do the builtins), but did not get to it for this release. Maybe
|
|
next time.

<h4>Changes for version 0.9.8</h4>
|
|
<ul>
|
|
<li>make install from source and package installation now installs the
|
|
header files. So, source for plugins can now<br>
|
|
      <b>#include <gkrellm/gkrellm.h></b>
|
|
<br>as a default so people
|
|
compiling plugins do not have to install them in the plugins source
|
|
tree or edit the location of gkrellm.h.
|
|
<li>Fixed a bug where DecalButtons were not destroyed when
|
|
gkrellm_destroy_panel() was called.
|
|
</ul>
|
|
|
|
<h4>Changes for version 0.9.7</h4>
|
|
<ul>
|
|
<li>IMPORTANT: init_plugin() returning NULL is now properly handled.
|
|
Any plugin which
|
|
finds it cannot install itself because some resource is not available
|
|
should not issue any error messages from the init_plugin() routine.
|
|
If the resource deficiency is serious (some feature not compiled into
|
|
the kernel, etc), the plugin should return NULL. However, if the
|
|
problem is resolvable (as in a permission problem or setup issue), then
|
|
the plugin should return the address of the monitor structure as normal,
|
|
but should then trap the problem and issue an error message in the
|
|
create_plugin() routine.
|
|
The reason
|
|
for this is that there is now a system wide plugins directory where
|
|
plugins for all users may be installed. This means plugins may be
|
|
loaded for users who do not want them enabled at all or
|
|
who do not currently have
|
|
permission to access resources needed by the plugin.
|
|
A message in the init_plugin() routine will appear each time GKrellM
|
|
is started and will probably just annoy the user. The proper place
|
|
for any messages, in the create_plugin() routine, will not be called
|
|
unless the user has asked for the plugin to be enabled. A message
|
|
here could let the user know what is needed to make the plugin
|
|
accessible, so you could issue the message and then return without
|
|
creating your monitor. And of course, your update routine needs
|
|
to be aware if the plugin has actually been created.
|
|
<li>A flag can be or'ed into a placement value so a plugin can be placed
|
|
after a builtin monitor instead of the default before the monitor.
|
|
For example, to place a plugin after the file system monitors, use <br>
|
|
(MON_FS | MON_INSERT_AFTER)<br>
|
|
I think a good rule to follow would be
|
|
to place a plugin before a particular
|
|
monitor when you are doing it for appearance (ie that is where the
|
|
plugin looks like it should go), but place the plugin "after" a monitor
|
|
when there is a functional similarity between the builtin and plugin.
|
|
Otherwise, a plugin which has a functional similarity and really should
|
|
be placed right next to a builtin monitor may not end up in the right
|
|
place if several plugins are asking to be placed in the same position.
|
|
If I can use current plugins as an example, I think the Mailwatch
|
|
would be a candidate to be placed after MON_MAIL because it has the
|
|
similarity and it is likely to be enabled at the same time as the builtin
|
|
mail monitor.
|
|
The others are probably OK being placed before any particular monitor.
|
|
The powerbook_pmu plugin does
|
|
not need to be placed after the builtin MON_APM because it will not
|
|
be enabled at the same time the builtin apm monitor is enabled.
|
|
</ul>
|
|
|
|
<h4>Changes for version 0.9.6</h4>
|
|
As of 0.9.6 I want to make name changes (and one prototype change)
|
|
for these four routines.
|
|
But for several versions, I'll keep them around to avoid breaking plugins.
|
|
<pre><font size="-1">
|
|
|
|
Decal *gkrellm_create_text_decal(Panel *p, gchar *, TextStyle *, Style *, gint, gint, gint);
|
|
Decal *gkrellm_create_pixmap_decal(Panel *, GdkPixmap *, GdkBitmap *, gint, Style *);
|
|
void gkrellm_draw_pixmap_decal(Panel *, Decal *, gint);
|
|
void gkrellm_draw_text_decal(Panel *, Decal *, gchar *, gint);
|
|
|
|
They are changed to:
|
|
|
|
Decal *gkrellm_create_decal_text(Panel *p, gchar *, TextStyle *, Style *, gint, gint, gint);
|
|
Decal *gkrellm_create_decal_pixmap(Panel *, GdkPixmap *, GdkBitmap *, gint, Style *, gint, gint);
|
|
void gkrellm_draw_decal_pixmap(Panel *, Decal *, gint);
|
|
void gkrellm_draw_decal_text(Panel *, Decal *, gchar *, gint);
|
|
</font></pre>
|
|
Plugins writers should migrate these four routines at their convenience.
|
|
This is simply done by replacing
|
|
the names, and in the case of gkrellm_create_decal_pixmap(), the following
|
|
two calls are equivalent:
|
|
<pre><font size="-1">
|
|
gkrellm_create_pixmap_decal(p, pixmap, mask, depth, style);
|
|
gkrellm_create_decal_pixmap(p, pixmap, mask, depth, style, -1, -1);
|
|
</font></pre>

<h4>Changes for version 0.9.0</h4>
|
|
|
|
The API for plugins is changed for version 0.9.0. There are a few
|
|
prototype changes and coding style changes. One change is necessary
|
|
because GKrellM now resizes and changes themes without restarting.
|
|
This changes the create_plugin() routine from a one time create
|
|
function to a create event function which can be repeatedly called.

-------------------------------------------------------------------
|
|
Coding style change: create_plugin()
|
|
|
|
-------------The old style--------------:
|
|
|
|
static void
|
|
create_plugin(GtkWidget *vbox)
|
|
{
|
|
Chart *chart;
|
|
Panel *p;

p = chart->panel = gkrellm_panel_new();
|
|
...
|

/* Create decals, krells. Configure panel, create panel, create chart */
|

--------------The new style-------------:
|
|
|
|
static void
|
|
create_plugin(GtkWidget *vbox, gint first_create)
|

================================================================
|
|
Coding style change: panel decal and krell lists are now a GList.
|
|
|
|
-------------The old style--------------:
|
|
Krell *k;
|
|
|
|
for (k = chart->panel->krell; k; k = k->next)
|
|
{
|
|
...
|
|
}
|
|
|
|
-------------The new style--------------:
|

Krell *k;
|
|
GList *list;
|
|
|
|
for (list = chart->panel->krell; list; list = list->next)
|
|
{
|
|
k = (Krell *) list->data;
|
|
...
|
|
}
|
|
|
|
Same change for panel->decal.
|
|
|
|
|
|
|
|
================================================================
|
|
Coding style change: gkrellm_default_textstyle() function defunct:
|
|
|
|
-------------The old function--------------:
|
|
gkrellm_default_textstyle(p->textstyle, TEXTSTYLE_XXX, style);
|
|
|
|
-------------Is replaced with several functions--------------:
|
|
p->textstyle = gkrellm_panel_textstyle(DEFAULT_STYLE);
|
|
p->textstyle = gkrellm_chart_textstyle(DEFAULT_STYLE);
|
|
p->textstyle = gkrellm_meter_textstyle(DEFAULT_STYLE);
|
|
p->textstyle = gkrellm_chart_alt_textstyle(DEFAULT_STYLE);
|
|
p->textstyle = gkrellm_panel_alt_textstyle(DEFAULT_STYLE);
|
|
p->textstyle = gkrellm_meter_alt_textstyle(DEFAULT_STYLE);
|
|
|
|
Use these functions in context. If you have created a chart with panel
|
|
and want to write text on the panel, use gkrellm_panel_textstyle().
|
|
|
|
|
|
================================================================
|
|
Function prototype changes (see gkrellm_public_proto.h):
|
|
|
|
Change gkrellm_create_krell() calls from:
|
|
k = gkrellm_create_krell(krell_image, &p->krell, style);
|
|
to
|
|
k = gkrellm_create_krell(p, krell_image, style);
|
|
|
|
|
|
Change gkrellm_create_xxx_decal() calls from:
|
|
d = gkrellm_create_text_decal(label, TEXTSTYLE_XXX, &p->decal,
|
|
style, x, y, w);
|
|
d = gkrellm_create_pixmap_decal(pixmap, mask, n_decals, &p->decal, style);
|
|
to
|
|
d = gkrellm_create_text_decal(p, label, textstyle, style, x, y, w);
|
|
d = gkrellm_create_pixmap_decal(p, pixmap, mask, n_decals, style);
|
|
|
|
|
|
================================================================
|
|
Monitor structure change:
|
|
The pre-spacer and post-spacer members are gone. There is no longer
|
|
a bg_spacer.
|
|
|
|
|
|
|
|
=================================================================
|
|
Notes:
|
|
If you create a krell you can reference it later in two ways (if
|
|
it is only a single krell in a panel or meter area):
|
|
|
|
1) save a pointer to the created krell, and reference that:
|
|
my_krell = gkrellm_create_krell(p, krell_image, style);
|
|
my_krell->full_scale = xx;
|
|
|
|
2) Don't save a pointer and reference the krell from the GList:
|
|
gkrellm_create_krell(p, krell_image, style);
|
|
KRELL(p)->full_scale = xx;
|
|
|
|
Note that in this case you cannot use the old reference style:
|
|
p->krell->full_scale = xx;
|
|
|
|
If you have more than one krell per panel or meter area, use the first
|
|
referencing method, save pointers to all the krells you create.
|
|
|
|
The same two referencing examples apply to decals as well.
|
|
|
|
|
|
=================================================================
|
|
New:
|
|
Decals can be converted to buttons. The plugins_example.c now
|
|
creates two decal buttons, so look there.
