Re: drawing to textview's gdk_window

[Luka Napotnik <luka napotnik gmail com>]

I now connected the expose-event signal to a callback function that
draws a rectangle to the widget. The problem is that the font is under
the rect. if I call g_signal_connect_after() and no text appears if I
call g_signal_connect() but the rect is visible.
I get the GdkWindow of the textview using:
win = gtk_text_view_get_window(GTK_TEXT_VIEW(widget),
GTK_TEXT_WINDOW_TEXT);

I want the rect to be in the background of the textview. Is there any
way to do that?

Greets,
Luka
