Subject: Re: How to shape a button
Hi; I looked at your code. First thing I noticed was that it didn't
come with a circle.xpm file. I replaced it with a stock debian logo,
mostly transparent :)
Moving on, for some reason, the BtnLogo object is never receiving a
configure-event. I even tried
gtk_widget_set_events(GDK_ALL_EVENTS_MASK), but to no avail. Since
this problem isn't interesting (at the moment) I changed it to
"realize" (interface.c:31) and it worked.
On a fairly pedantic note: GtkPixmap is deprecated as of 2.0. Use
GtkImage instead.
Another minor issue was that you were trying to set the button to be
decorationless, but it's not a GtkWindow. I fixed this by passing
window1 as the user_data parameter to your callback.
So then I uncommented the bit about putting the image in the container
(make sure you don't have a GtkLabel in there already; use BtnLogo =
gtk_button_new() instead), and the final thing: you need to show the
image: gtk_widget_show(img);
Attached is the new code. Enjoy.
