Hello,
I'm pretty new to gnome development and I have trouble understanding how
to draw your own things. My eventual objective is to make a hearts game,
but that's a long way off. At the moment I am having trouble to set a
background in my UI, much like the green striped background in AisleRiot.
I am using libglade for my UI. The main window (where the cards are
going to be) is a GtkDrawingArea called "table". I load up an image and
try to fill the drawing area with it, but it doesn't show it. I've tried
looking ar AilseRiot and see how they do it, but I can't figure it out.
Here's my code, with comments as to what each step is supposed to do.
Any idea what I am doing wrong? Probably lots :-) Thanks in advance!
int main (int argc, char *argv[])
{
GtkWidget *table_widget;
GdkGC *table;
/* Start up glade and show the UI */
gnome_init (PACKAGE, VERSION, argc, argv);
glade_gnome_init ();
xml = glade_xml_new (PACKAGE_SOURCE_DIR"/hearts.glade", NULL, NULL);
glade_xml_signal_autoconnect (xml);
/* Load the background pixmap. get_pixmap() uses
gdk_pixbuf_new_from_file() to load the image and returns a GdkPixmap
pointer. I got this from the AisleRiot code. background_pixmap is a
global. It does return a valid image, not NULL. */
background_pixmap = get_pixmap(PACKAGE_SOURCE_DIR"/pixmaps/baize.png");
/* From what I read, I need a GDK Graphics Context to draw in, so here
I create one. I can verify that it does return a GdkGC, and not NULL */
table_widget = glade_xml_get_widget (xml, "table");
table = gdk_gc_new (table_widget->window);
/* This should fill the GC with the background image, right? */
gdk_gc_set_tile (table, background_pixmap);
gdk_gc_set_fill (table, GDK_TILED);
/* wait for events */
gtk_main ();
/* bye bye */
return 0;
}
