implements it in TaskGroupingProxyModel.</p>
<p>The purpose of this data role is as a means of signalling to a Qt<br />
Quick delegate for a top-level row that a property of the item -<br />
namely the number of children it has - has changed. Qt Quick's poor<br />
support for tree models makes the existing way of signaling this<br />
(rowsInserted) prohibitive to use.</p>
<p>The Task Manager applet needs this info because it's in charge of<br />
telling the window manager about the screen coordinates of window<br />
delegates (through support code in this library). When a window is<br />
directly added to an existing group, there is no new delegate<br />
created, nor does the existing delegate change position. An<br />
increase of ChildCount will be used in this case to decide to<br />
publish delegate geo for the new window.</p>
