Re: Simple GDK app segfaults for unknown reason
hi,
i'd say you forgot to end the call with a NULL. also, as far as i know
the standard way to use GError is to have a 'GError *error;' variable
and then pass the pointer to it. in your case:
GError *error = NULL;
GdkPixbuf *pixbuf = gdk_pixbuf_new_from_file(input.jpg, error);
gdk_pixbuf_save(pixbuf, output.bmp, bmp, error, NULL);
but of course it doesn't make sense to use GError if you don't look at
the error variable afterwards; e.g. to display the error message if
there was an error and free the error variable with g_error_free. i use
in my projects a function to check GErrors (called every time i used a
function that i passed a GError to):
/**
Print the contents of a GError (if it was set).
If abort_program is TRUE, we free the memory
and exit the game.
@param error The GError we check.
@param abort_program Whether or not we continue or exit the program.
*/
void
misc_print_error(GError **error, gboolean abort_program)
{
if(*error == NULL)
return;
g_warning(error message: %s\n, (*error)-message);
g_error_free(*error);
*error = NULL;
if(abort_program)
main_exit_program(EXIT_PRINT_ERROR, NULL);
}
i hope i could help.

Hi! I want to change the color of the text in single entries of a tree view. Does anybody know how to do this?

Re: gtkfilechooser buttons
You can consider using a dinamically generated filechooser, instead of a statically generated one (i.e. that created by Glade) by means of gtk_file_chooser_dialog_new; in this way, you can select a GTK_FILE_CHOOSER_ACTION_OPEN behaviour or a GTK_FILE_CHOOSER_ACTION_SAVE one, depending on your current operation. well, the behaviour of the widget is all right. but why doesn't the button image change when i set to save mode? i mean, the folder browser and the other parts of the window are ok. shouldn't the appearance of the filechooser widget change when i set the action with gtk_file_chooser_set_action ? gyz -- Today is a good day to bribe a high-ranking public official. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: How can I access gtk_tree_view declared in interface.c from callback.c ?
you have to do a

before you can use the treeview. as far as i know (i might be wrong) in the
newer glade versions one cannot use the 'user_data' stuff in the callback
functions.
the widgets aren't declared in the callback file, you have to look them up
using a widget from the same window and 'lookup_widget' before you can use
them.

load it. but this shouldn't prevent the whole system of changing the
shortcuts from working.
