Example:
/* One of the things WinActivate does is set the given window to be active (and sets
the currently active window to inactive) then calls DrawWinBorder to redraw the
windows border.
*/
.
.
.
w->Flags |= WF_ACTIVE;
DrawWinBorder( w, &w->Window );
.
.
.
/* If an application must completely redraw its window (such as the example below
where it is using the WF_DUP_SCR feature of WinOpen), it must also redraw its
border
*/
case CM_WPAINT:
DrawWinBorder( &appW, &appW.Window );
WinBackupToScr( &appW );
break;
