Method
GdkWindowshape_combine_region
Declaration [src]
void
gdk_window_shape_combine_region (
GdkWindow* window,
const cairo_region_t* shape_region,
gint offset_x,
gint offset_y
)
Description [src]
Makes pixels in window outside shape_region be transparent,
so that the window may be nonrectangular.
If shape_region is NULL, the shape will be unset, so the whole
window will be opaque again. offset_x and offset_y are ignored
if shape_region is NULL.
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.
Parameters
shape_region-
Type:
cairo_region_tRegion of window to be non-transparent.
The argument can be NULL.The data is owned by the caller of the method. offset_x-
Type:
gintX position of
shape_regioninwindowcoordinates. offset_y-
Type:
gintY position of
shape_regioninwindowcoordinates.
