32 * WIN_HaveToDelayNCPAINT
34 * Currently, in the Wine painting mechanism, the WM_NCPAINT message
35 * is generated as soon as a region intersecting the non-client area
36 * of a window is invalidated.
38 * This technique will work fine for all windows whose parents
39 * have the WS_CLIPCHILDREN style. When the parents have that style,
40 * they are not going to override the contents of their children.
41 * However, when the parent doesn't have that style, Windows relies
42 * on a "painter's algorithm" to display the contents of the windows.
43 * That is, windows are painted from back to front. This includes the
46 * This method looks at the current state of a window to determine
47 * if the sending of the WM_NCPAINT message should be delayed until
48 * the BeginPaint call.
51 * wndPtr - A Locked window pointer to the window we're
53 * uncFlags - This is the flag passed to the WIN_UpdateNCRgn
54 * function. This is a shortcut for the cases when
55 * we already know when to avoid scanning all the
56 * parents of a window. If you already know that this
57 * window's NCPAINT should be delayed, set the
58 * UNC_DELAY_NCPAINT flag for this parameter.
60 * This shortcut behavior is implemented in the
64 static BOOL
WIN_HaveToDelayNCPAINT(
68 WND
* parentWnd
= NULL
;
71 * Test the shortcut first. (duh)
73 if (uncFlags
& UNC_DELAY_NCPAINT
)
77 * The UNC_IN_BEGINPAINT flag is set in the BeginPaint
78 * method only. This is another shortcut to avoid going
79 * up the parent's chain of the window to finally
80 * figure-out that none of them has an invalid region.
82 if (uncFlags
& UNC_IN_BEGINPAINT
)
86 * Scan all the parents of this window to find a window
87 * that doesn't have the WS_CLIPCHILDREN style and that
88 * has an invalid region.
