πŸ¦‹ ARGUMENTS πŸ¦‹

  • Tk_Window tkwin (in) β€” the token for the top-level window you wanna move, bestie 🫢
  • int x (in) β€” the 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 ✨

πŸ‘‘ DESCRIPTION πŸ‘‘

okay so the big rule: in general, a window should never set its own position 😀 this should be done only by the geometry manager that’s 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 πŸ’«

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 πŸ“

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 ⏳ iconic behavior, honestly.
