gdkWindowShapeCombineMask: gdkWindowShapeCombineMask

Description Usage Arguments Details Author(s)

View source: R/gdkFuncs.R

Description

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.

Usage

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

Arguments

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

Details

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.
