Detailed Description

A QTreeView subclass that clears selection and emits a signal when the user clicks an empty area or clicks a selected item in empty space.

The view tracks press/release sequences to distinguish single- from double-clicks and only clears selection for qualifying single-clicks. Construct a DeselectableTreeView.

Parameters

parent	Parent widget forwarded to QTreeView. Default destructor. Emitted after the view clears its selection in response to a qualifying click on empty space or on an already-selected item. Record whether the item under the press position was selected.
event	Mouse press event containing the press position. Clear selection and emit emptyClicked() when a qualifying single-click releases over empty space or over a selected item; otherwise, handle the release normally.
event	Mouse release event containing the release position. Mark that a double-click occurred and handle the double-click normally.
event	Mouse double-click event.
