Clicked event on GtkButton
Does it make any difference, generating clicked event using mouse click OR
gtk_button_clicked() call
My clicked event callback rightly changes background colour when clicked using
mouse however change does not reflect when the event is generated using
gtk_button_clicked() with following code :
Gtkwidget *button1;
void click_button1(GtkWidget *widget, gpointer data)
{
GdkColor color;
color.red = 27000;
color.green = 30325;
color.blue = 34181;
gtk_widget_modify_bg(button1, GTK_STATE_NORMAL, color);
gtk_widget_show_now(GTK_BUTTON(button1));
}
Any Clue ?

gdk-pixbuf-query-loaders on Windows does nothing.
Some years ago I was building GNU Denemo on windows and had some help with running gdk-pixbuf-query-loaders. For some years now we have been building the program by cross-compiling on GNU/Linux systems. I don't think we have ever sorted out how to run the gdk-pixbuf-query-loaders automatically on installation, however. As a first step, I have tried to run gdk-pixbuf-query-loaders.exe manually (with elevated permissions). The program executes but does not seem to perform any I/O. It is built without debug symbols unfortunately, but running it under gdb it will break at fopen a couple of times, but otherwise there is no sign of it doing anything. Does anyone have any idea what might be wrong? (I should add that the program runs fine - apart from not loading .svg files for which a loader is present - making extensive use of gtk) Richard Shann ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Spell checking in GIO

More precisely, here are the two classes from gtkhtml that can go in GIO: https://git.gnome.org/browse/gtkhtml/tree/components/editor/gtkhtml-spell-language.h https://git.gnome.org/browse/gtkhtml/tree/components/editor/gtkhtml-spell-checker.h Some API tweaks may be needed, but I think these features belong to GIO, not GTK+. We can also hide these features and adapt the GTK+ widgets directly, and add some widgets for the spell checking (a menu or a dialog window with the list of available languages, and a dialog window for the spell checking of a GtkTextView). But this would be less flexible, and custom widgets would need to use Enchant. Anyway, what can be extracted from GtkhtmlSpellLanguage is the decoding of language codes, fr_BE - French (Belgium). I proposed last year to add functions in glib for doing that (it reads the iso-codes data). Even if this is not added to the public API, it can be useful to have this feature separately, so other projects can copy the code.

Is this a cast?
Apologies if this is a duplicate post. I am having some email trouble. Hi Everyone I have been reading GTK+ Development by Krause for some time. Almost everything makes sense but I don't really understand this: g_signal_connect_swapped( G_OBJECT ( button1 ) ... continues.. on.. button1 is type GtkWidget, is it being cast to type G_OBJECT ? I am used to seeing casts like: number1 = (int) another_num but I suppose the parenthesis can actually go around the type or the variable, correct? If I am indeed reading this write, it seems like most widgets start off as GtkWidget types but then are recast to more specific objects during function calls, does this sound right? -Patrick ___ gtk-devel-list mailing list gtk-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-devel-list

This is the wrong list (it's about the development of GTK itself); you want gtk-app-devel (which is about working on GTK applications). That said, g_signal_connect_swapped( G_OBJECT ( button1 ) ... continues.. on.. button1 is type GtkWidget, is it being cast to type G_OBJECT ? Sort of, but with type checking. It's not a straight cast; it's a macro defined in glib-2.0/gobject.h. I am used to seeing casts like: number1 = (int) another_num but I suppose the parenthesis can actually go around the type or the variable, correct? No. In a regular C cast you can't put the parentheses around the variable name.
