I used it to access objects which are placed several levels above the
current object in the tree. Avoiding parent.parent.parent...
constructs.
It's used in basewindow.lzx in a similar way:
<!--- Called onmousedown when this is the frontmost window to see if
the click should bring a different window to the front.
@keywords private -->
<method name="_checkmouse" args="v"> <![CDATA[
if (v == null || v == this) return;
// check if a modal dialog is frontmost
if (lz.ModeManager.hasMode( this )) return;
var foundwindow = v.searchParents('haswindowfocus');
if (foundwindow != null) {
foundwindow.setWindowFocus(true);
}
]]>
</method>
