gdkCursorNewFromPixmap: gdkCursorNewFromPixmap

Description

Creates a new cursor from a given pixmap and mask. Both the pixmap and mask must have a depth of 1 (i.e. each pixel has only 2 values - on or off). The standard cursor size is 16 by 16 pixels. You can create a bitmap from inline data as in the below example.

Usage

gdkCursorNewFromPixmap(source, mask, fg, bg, x, y)

Arguments

Value

[GdkCursor] a new GdkCursor.
