Description Anatoly Spektor 2012-08-24 10:07:31 EDT

Tooltip.configure() widget uses these two function:  

                int /*long*/ rgn = OS.gdk_region_polygon (polyline, polyline.length / 2, OS.GDK_EVEN_ODD_RULE);
		 OS.gdk_window_shape_combine_region (window, rgn, 0, 0);

First one can be replicated with cairo, however I believe that second one, can be only replicated with use of GTK 3.0 functions.

Method gdk_region_polygon () produces warnings and errors, and without its replacement, SWT cannot be built against 2.4.

Here is the patch I propose:

http://fedorapeople.org/cgit/aspektor/public_git/eclipse.platform.swt.git/commit/?h=gdk_region


Patch is guarded with GTK 3.0 as functions: 
           gdk_cairo_region_create_from_surface();
          gtk_widget_shape_combine_region ();
is GTK+ 3.0 functions.

Note: The patch has not been fully tested, as it is not possible to build against 3.0, however, without removing such issues it is not possible to build.

If there should be some other stated procedure on dealing with issues from:

 please let me know.
