DESCRIPTION
In general, a window should never set its own position; this should be
done only by the geometry manger that is responsible for the window.
For top-level windows the window manager is effectively the geometry
manager; Tk provides interface code between the application and the
window manager to convey the application's desires to the geometry
manager. The desired size for a top-level window is conveyed using the
usual Tk_GeometryRequest mechanism. The procedure
Tk_MoveToplevelWindow may be used by an application to request a
particular position for a top-level window; this procedure is similar
in function to the wm geometry Tcl command except that negative offsets
cannot be specified. It is invoked by widgets such as menus that want
to appear at a particular place on the screen.
When Tk_MoveToplevelWindow is called it does not immediately pass on
the new desired location to the window manager; it defers this action
until all other outstanding work has been completed, using the
Tcl_DoWhenIdle mechanism.
