Hi!
Im sending you code from the project gtk-book,
http://gtkbook.sourceforge.net/
The function make_shapedwidget() should help.
To choose the shape of the widget change the
mask in the file "circle.xpm".
<CODE>
#include<gtk/gtk.h>
#include<gtk/gtkitemfactory.h>
#include<glib/gprintf.h>
gboolean configure_event(GtkWidget *w,gpointer data)
{
//make a shaped mask
GdkPixmap *pix;
GdkBitmap *bit;
GdkColor c={0};
pix=gdk_pixmap_create_from_xpm(w->window,&bit,&c,"circle.xpm");
gdk_window_shape_combine_mask(GDK_WINDOW(w->window),bit,100,100);
gtk_window_set_decorated(GTK_WINDOW(w),FALSE);
return TRUE;
}
GtkWidget * make_shapedwidget(void)
{
GtkWidget *w;
w=gtk_window_new(GTK_WINDOW_TOPLEVEL);
g_signal_connect(G_OBJECT(w),"configure_event",G_CALLBACK(configure_event),NULL);
g_signal_connect(G_OBJECT(w),"destroy",G_CALLBACK(gtk_main_quit),NULL);
gtk_container_add(GTK_CONTAINER(w),gtk_color_selection_new());
return w;
}
</CODE>
Cheers
