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

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