Description Owen Taylor 2002-06-17 20:56:03 UTC 
gtk_widget_get_pango_context() contains:

  context = gtk_object_get_data_by_id (GTK_OBJECT (widget),
quark_pango_context);
  if (context)
    {
      screen = g_object_get_data (G_OBJECT (context), "gdk-pango-screen");
      if (screen && (screen != gtk_widget_get_screen (widget)))
	  context = NULL;
    }
 
If this is right thing to do, then we need to add
gdk_pango_context_get_screen(), since peeking at private object 
data like this is not allowed.

I'm a little concerned about colormap changes and the widget's
pango context ... we don't seem to handle this currently. Handling
it might automatically have the effect of handling screen changes
since a screen change automatically implies a colormap change.

        * gtk/gtkwidget.c (gtk_widget_get_pango_context): Note
        that get_pango_context() is not "until death does us
        part", but "until the screen changes".

        * gtk/gtkwidget.c (gtk_widget_create_pango_context): Add
        a MULTIHEAD warning.

        * gtk/gtkwidget.c (do_screen_change): Clear pango context
        for widget if set.

Ignoring colormap problems. Colormap changes after a widget
is realized already don't work.
