* WIN_HaveToDelayNCPAINT
|
|
*
|
|
* Currently, in the Wine painting mechanism, the WM_NCPAINT message
|
|
* is generated as soon as a region intersecting the non-client area
|
|
* of a window is invalidated.
|
|
*
|
|
* This technique will work fine for all windows whose parents
|
|
* have the WS_CLIPCHILDREN style. When the parents have that style,
|
|
* they are not going to override the contents of their children.
|
|
* However, when the parent doesn't have that style, Windows relies
|
|
* on a "painter's algorithm" to display the contents of the windows.
|
|
* That is, windows are painted from back to front. This includes the
|
|
* non-client area.
|
|
*
|
|
* This method looks at the current state of a window to determine
|
|
* if the sending of the WM_NCPAINT message should be delayed until
|
|
* the BeginPaint call.
|
|
*
|
|
* PARAMS:
|
|
* wndPtr - A Locked window pointer to the window we're
|
|
* examining.
|
|
* uncFlags - This is the flag passed to the WIN_UpdateNCRgn
|
|
* function. This is a shortcut for the cases when
|
|
* we already know when to avoid scanning all the
|
|
* parents of a window. If you already know that this
|
|
* window's NCPAINT should be delayed, set the
|
|
* UNC_DELAY_NCPAINT flag for this parameter.
|
|
*
|
|
* This shortcut behavior is implemented in the
|
|
* RDW_Paint() method.
