Hi,
It appears that the 'irregularly shaped' windows which used to be
possible by using now-deprecated GDK code even without full
compositing available, are no longer possible using non-deprecated
code.
Using the old deprecated code, a GdkRegion could be created with the
desired window shape (with the region defining fully transparent and
fully opaque areas) and a call to gdk_window_shape_combine_region to
bring it about.
I've been trying to work around this but feel like a dog running in
circles chasing my tail.
gdk_window_shape_combine_region is not deprecated, but GdkRegion will
be replaced in GTK3.0 with cairo_region_t for which there is no
gdk_window_shape_combine_region equivalent. Furthermore the
gdk_region_polygon call necessary to create the GdkRegion of the
desired shape, is deprecated without replacement.
So I look into gdk_window_shape_combine_mask instead, but
gdk_bitmap_create_from_data is of course deprecated. The docs do at
least suggest cairo alternatives, but none of which are compatible
with gdk_window_shape_combine_mask.
I'm just going to start looking into these functions:
cairo_xlib_surface_create_for_bitmap
as they *might* do what I wish.
Please please tell me if there's anyway around this mess. I can't
force or assume use of compositing.
Cheers,
James.
