gdkWindowShapeCombineMask: gdkWindowShapeCombineMask
In RGtk2: R Bindings for Gtk 2.8.0 and Above

Description Usage Arguments Details Author(s)

Applies a shape mask to window. Pixels in window corresponding to set bits in the mask will be visible; pixels in window corresponding to unset bits in the mask will be transparent. This gives a non-rectangular window.

1 2	gdkWindowShapeCombineMask(object, shape.mask = NULL, offset.x, offset.y)

`object`	a `GdkWindow`
`shape.mask`	shape mask
`offset.x`	X position of shape mask with respect to `window`
`offset.y`	Y position of shape mask with respect to `window`

If mask is NULL, the shape mask will be unset, and the x/y parameters are not used.

On the X11 platform, this uses an X server extension which is widely available on most common platforms, but not available on very old X servers, and occasionally the implementation will be buggy. On servers without the shape extension, this function will do nothing.

This function works on both toplevel and child windows.
