I am trying to create a Gtk3 Window with a custom input mask, so that the window wouldn't receive any mouse clicks. This is a piece of code that I've came up with:
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, w , h) surface_ctx = cairo.Context(surface) surface_ctx.set_source_rgba(1.0, 1.0, 1.0, 0.0) surface_ctx.set_operator(cairo.OPERATOR_SOURCE) surface_ctx.paint() reg = Gdk.cairo_region_create_from_surface(surface) widget.input_shape_combine_region(reg)
Unfortunately call to Gdk.cairo_region_create_from_surface() fails with this error:
Traceback (most recent call last): File "../kazam/frontend/window_region.py", line 144, in cb_draw reg = Gdk.cairo_region_create_from_surface(surface) File "/usr/lib/python2.7/dist-packages/gi/types.py", line 43, in function return info.invoke(*args, **kwargs) TypeError: Couldn't find conversion for foreign struct 'cairo.Region'
After inspecting Gdk-3.0.gir file I am somewhat baffled. Clearly I am doing something wrong (or there's something wrong with introspection?). Any advice will be appreciated.
