Tk_MoveToplevelWindow - Adjust the position of a top-level window
#include <tk.h>
Tk_MoveToplevelWindow(tkwin, x, y)
- Tk_Window tkwin (in)
- Token for top-level window to move.
- int x (in)
- New x-coordinate for the top-left pixel of tkwin's
border, or the top-left pixel of the decorative border supplied for
tkwin by the window manager, if there is one.
- int y (in)
- New y-coordinate for the top-left pixel of tkwin's
border, or the top-left pixel of the decorative border supplied for
tkwin by the window manager, if there is one.
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 doesn't
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 Tk_DoWhenIdle mechanism.
