setDesktop
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
desktop
the number of a workspace, or -1
