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
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:
#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);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.
gkrellm_spacers_set_types(GkrellmMonitor *mon, gint top, gint bottom);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.
Style *gkrellm_meter_style_by_name(gchar *name); Style *gkrellm_panel_style_by_name(gchar *name); Style *gkrellm_chart_style_by_name(gchar *name);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.
Style margin changes for more layout control. Usually these will be set by a theme author in the gkrellmrc:
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 *);The DecalButton callback function prototype adds a "gpointer data" so you don't have to reference button->data.
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);
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.
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.
To check if you need changes, #ifdef out the part that will be cut and see if you get warnings compiling with -Wall.
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.Added some handy utility routines (most were already in gkrellm_private_proto.h without a gkrellm_ prefix):
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();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.
void gkrellm_get_top_bottom_margins(Style *s, gint *top, gint *bot)
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.
Style *gkrellm_copy_style(Style *src_style);
TextStyle *gkrellm_copy_textstyle(TextStyle *src_style);
Previously I had suggested
copying a style to a plugin local style like so:
Style *my_style, *style;
style = gkrellm_meter_style(DEFAULT_STYLE);
my_style = gkrellm_style_new0();
*my_style = *style;
But I goofed and this is no good. If you have such code please change it.
It should now be done like so:
Style *my_style, *style;
style = gkrellm_meter_style(style_id);
my_style = gkrellm_copy_style(style);
NOTE: 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.
#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
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:
#include <gkrellm/gkrellm.h>
#if (VERSION_MAJOR==0) && (VERSION_MINOR<10)
#error This plugin requires GKrellM version >= 0.10.0
#endif
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!
#ifdef GRAVITY #define MY_PLACEMENT (MON_APM | GRAVITY(8)) #else #define MY_PLACEMENT (MON_APM) #endifIf 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.
Final release check list (some details are below):
- Fix GK struct references - only xxx_tick and debug references are OK.
- Consider adding style_id support - use the new functions.
- Consider using gkrellm_load_image() to load custom #included images.
Details
New functions (see plugin programmers reference):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);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).Code references like these are a problem:
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.Fix them like this: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));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.Here's something that might help:
- Make your plugin compilable under 0.9.x or 0.10.x by doing this:
In a header or at the top of your source file:#if ((VERSION_MAJOR>0)||(VERSION_MINOR>9)) #define PLUGIN_STYLE style_id static gint style_id; #else #define PLUGIN_STYLE DEFAULT_STYLE #endifAccess styles and images by using PLUGIN_STYLE as an argument. And in the init_plugin() routine, add this:#if ((VERSION_MAJOR>0)||(VERSION_MINOR>9)) style_id = gkrellm_add_meter_style(&plugin_mon, "somename"); #endif- 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.
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: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" }; ... GtkWidget *text; ... text = gtk_text_new(NULL, NULL); gkrellm_add_info_text(text, info_text, sizeof(info_text) / sizeof(gchar *)); ...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: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") };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.
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);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:
gkrellm_create_pixmap_decal(p, pixmap, mask, depth, style);
gkrellm_create_decal_pixmap(p, pixmap, mask, depth, style, -1, -1);
-------------------------------------------------------------------
Coding style change: create_plugin()
-------------The old style--------------:
static void
create_plugin(GtkWidget *vbox)
{
Chart *chart;
Panel *p;
chart = gkrellm_chart_new0();
p = chart->panel = gkrellm_panel_new();
...
/* Create decals, krells. Configure panel, create panel, create chart */
...
gtk_signal_connect(GTK_OBJECT(p->drawing_area), "expose_event",
(GtkSignalFunc) panel_expose_event, NULL);
gtk_signal_connect(GTK_OBJECT(chart->drawing_area),"expose_event",
(GtkSignalFunc) chart_expose_event, NULL);
}
--------------The new style-------------:
static void
create_plugin(GtkWidget *vbox, gint first_create)
{
Chart *chart;
Panel *p;
if (first_create)
{
chart = gkrellm_chart_new0();
p = chart->panel = gkrellm_panel_new();
}
else
{
gkrellm_destroy_krell_list(p);
gkrellm_destroy_decal_list(p);
}
...
/* Create decals, krells. Configure panel, create panel, create chart
| just as before.
|
| If you create any local pixmaps, widgets, etc you should destroy
| them or not create them again if this is not the first_create to
| avoid memory leaks. You could test for first_create or objects != NULL.
| See the plugin_example.c for code marked with MMM.
*/
...
if (first_create)
{
gtk_signal_connect(GTK_OBJECT(p->drawing_area), "expose_event",
(GtkSignalFunc) panel_expose_event, NULL);
gtk_signal_connect(GTK_OBJECT(chart->drawing_area),"expose_event",
(GtkSignalFunc) chart_expose_event, NULL);
}
}
================================================================
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

=================================================================
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.
