|

// Synopsis: This method populates hItem's(parent folder) children into
|
|
// the tree control.
|
|
// In the first phase, Expand notifications are sent to the snapin
|
|
// which causes all children to be inserted to the master scope
|
|
// tree.
|
|
// In the second phase, we step through these children and insert
|
|
// them to the tree controls.
|
|
// For performance reasons, we walk the child list in reverse order
|
|
// (last child to first child) inserting the current item at the
|
|
// first position.
|
|
// If we were to walk the child list in normal order (first to last
|
|
// child) inserting the current item at the last position -- the
|
|
// underlying tree control takes time that grows exponentially in
|
|
// the number of children (as opposed to linearly).
|
|
//
|
|
// Arguments: hItem: the parent
|
|
//
|
|
// Returns: TRUE on success and FALSE on failure

|
* rectangle problem"): The tree control has code to invalidate the
|
|
* selected item when focus is lost. If we have a temp selection, we've
|
|
* made a temporary item appear selected by fiddling with TVIS_SELECTED
|
|
* states (see ScSet/RemoveTempSelection). We need to do it that way
|
|
* instead of sending TVM_SELECTITEM so we don't get unwanted
|
|
* TVN_SELCHANGED notifications, but it has the side effect of fooling
|
|
* the tree control's WM_KILLFOCUS handler into invalidating the non-temp
|
|
* selected item instead of the item that is really showing selection, the
|
|
* temp item.
|
|
*
|
|
* This bug was originally fixed with a sledgehammer, specifically by
|
|
* forcing the entire main frame and all of its children to be totally
|
|
* redrawn after displaying any context menu. This caused bug 139541
|
|
* (in the "Windows Bugs" database).
|
|
*
|
|
* A much more surgical fix to 114948, which also avoids 139541, is to
|
|
* manually invalidate the temporarily selected item. It's important
|
|
* that we do this after calling the base class so it will be redrawn
|
|
* in the "we don't have the focus" color (usually gray), rather than
|
|
* the standard selection color.
