gdkCursorNewFromPixmap
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.
gdkCursorNewFromPixmap(source, mask, fg, bg, x, y)
|
the pixmap specifying the cursor. |
|
the pixmap specifying the mask, which must be the same size as
|
|
the foreground color, used for the bits in the source which are 1. The color does not have to be allocated first. |
|
the background color, used for the bits in the source which are 0. The color does not have to be allocated first. |
|
the horizontal offset of the 'hotspot' of the cursor. |
|
the vertical offset of the 'hotspot' of the cursor. |
