[Ucgui] dialog box 5--mouse position and move window

>_< " This section mainly gets the position of the mouse and sets the window to be movable. Where the Setup window can be moved with framewin_setmoveable (Hframewin, 1) on the line. While getting the mouse position is the location information transmitted by the State structure of the Wm_touch message (see 56, 572 rows).
