Any of the return location arguments to this function may be null, if you aren’t interested in getting the value of that field.
The X and Y coordinates returned are relative to the parent window of window, which for toplevels usually means relative to the window decorations (titlebar, etc.) rather than relative to the root window (screen-size background window).
On the X11 platform, the geometry is obtained from the X server, so reflects the latest position of window; this may be out-of-sync with the position of window delivered in the most-recently-processed #GdkEventConfigure. [gdk.window.Window.getPosition] in contrast gets the position from the most recent configure event.
Note
If window is not a toplevel, it is much better
to call [gdk.window.Window.getPosition], [gdk.window.Window.getWidth] and [gdk.window.Window.getHeight] instead, because it avoids the roundtrip to the X server and because these functions support the full 32-bit coordinate space, whereas [gdk.window.Window.getGeometry] is restricted to the 16-bit coordinates of X11.
Parameters
x | return location for X coordinate of window (relative to its parent) |
y | return location for Y coordinate of window (relative to its parent) |
width | return location for width of window |
height | return location for height of window |
