set_desktop

Sets the workspace on which applications will be launched.

This only works when running under a window manager that supports multiple workspaces, as described in the Extended Window Manager Hints. Specifically this sets the `_NET_WM_DESKTOP` property described in that spec.

This only works when using the X11 backend.

When the workspace is not specified or desktop is set to -1, it is up to the window manager to pick one, typically it will be the current workspace.

Parameters:

this	a `GdkAppLaunchContext`
desktop	the number of a workspace, or -1
