|
|
* @GDK_ANCHOR_FLIP_Y: allow flipping anchors vertically
|

* @GDK_ANCHOR_SLIDE_X: allow sliding surface horizontally

* @GDK_ANCHOR_RESIZE_X: allow resizing surface horizontally

*
|
|
* Positioning hints for aligning a surface relative to a rectangle.
|
|
*
|
|
* These hints determine how the surface should be positioned in the case that
|
|
* the surface would fall off-screen if placed in its ideal position.
|
|
*
|
|
* For example, %GDK_ANCHOR_FLIP_X will replace %GDK_GRAVITY_NORTH_WEST with
|
|
* %GDK_GRAVITY_NORTH_EAST and vice versa if the surface extends beyond the left
|
|
* or right edges of the monitor.
|
|
*
|
|
* If %GDK_ANCHOR_SLIDE_X is set, the surface can be shifted horizontally to fit
|
|
* on-screen. If %GDK_ANCHOR_RESIZE_X is set, the surface can be shrunken
|
|
* horizontally to fit.
|
|
*
|
|
* In general, when multiple flags are set, flipping should take precedence over
|
|
* sliding, which should take precedence over resizing.
