/*
|
||||
* XpValidateTree - a validateTree routine which ignores overlapping
|
||||
* top-level windows when computing the clip lists for such windows.
|
||||
* This can be used by any driver which maintains a separate memory
|
||||
* store for each top-level window (with its respective children).
|
||||
* If the pParent is not the root window, then miValidateTree
|
||||
* is used unmodified.
|
||||
*
|
||||
* The strategy if pParent is the root is to save off the
|
||||
* current values of pParent->firstChild and pParent->lastChild,
|
||||
* replacing both with the single child of interest. We save off
|
||||
* pChild->prevSib and pChild->nextSib, and replace them with NullWindow.
|
||||
* We save off pParent->clipList, and replace it with
|
||||
* pParent->winSize - pChild->winSize. We then call miValidateTree
|
||||
* to do the needed ComputeClips on the pChild's heirarchy.
|
||||
* pParent's clipList is then recomputed based on the sizes
|
||||
* of its children, and the saved pointers are restored.
|
||||
* The trees associated with the siblings of pChild must be descended
|
||||
* and cleaned of any marks (i.e. the valdata pointer freed, and set to NULL),
|
||||
* and pParent' AfterValidate structure's exposed field must be updated.
