When a popup is already showing, and gdk_surface_present_popup() is called, if the layout didn't change, we're not really interested in relayouting. In the future, we'll be able to get notified if position of the popup would change by some environmental changes, but until then, just don't support it.

* GdkAnchorHints:
|
|
* @GDK_ANCHOR_FLIP_X: allow flipping anchors horizontally
|
|
* @GDK_ANCHOR_FLIP_Y: allow flipping anchors vertically
|
|
* @GDK_ANCHOR_SLIDE_X: allow sliding surface horizontally
|

|
|
* @GDK_ANCHOR_RESIZE_X: allow resizing surface horizontally

|
* @GDK_ANCHOR_FLIP: allow flipping anchors on both axes

|
|
*
|
|
* 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.
