67 * WIN_HaveToDelayNCPAINT
69 * Currently, in the Wine painting mechanism, the WM_NCPAINT message
70 * is generated as soon as a region intersecting the non-client area
71 * of a window is invalidated.
73 * This technique will work fine for all windows whose parents
74 * have the WS_CLIPCHILDREN style. When the parents have that style,
75 * they are not going to override the contents of their children.
76 * However, when the parent doesn't have that style, Windows relies
77 * on a "painter's algorithm" to display the contents of the windows.
78 * That is, windows are painted from back to front. This includes the
81 * This method looks at the current state of a window to determine
82 * if the sending of the WM_NCPAINT message should be delayed until
83 * the BeginPaint call.
86 * wndPtr - A Locked window pointer to the window we're
88 * uncFlags - This is the flag passed to the WIN_UpdateNCRgn
89 * function. This is a shortcut for the cases when
90 * we already know when to avoid scanning all the
91 * parents of a window. If you already know that this
92 * window's NCPAINT should be delayed, set the
93 * UNC_DELAY_NCPAINT flag for this parameter.
95 * This shortcut behavior is implemented in the
99 static BOOL
WIN_HaveToDelayNCPAINT(
103 WND
* parentWnd
= NULL
;
106 * Test the shortcut first. (duh)
108 if (uncFlags
& UNC_DELAY_NCPAINT
)
112 * The UNC_IN_BEGINPAINT flag is set in the BeginPaint
113 * method only. This is another shortcut to avoid going
114 * up the parent's chain of the window to finally
115 * figure-out that none of them has an invalid region.
117 if (uncFlags
& UNC_IN_BEGINPAINT
)

122 * that doesn't have the WS_CLIPCHILDREN style and that
123 * has an invalid region.
