<element name="TTreeFilterEdit.EditKeyDown">
<short>
Implements the OnKeyDown event handler for the Edit on the control.
</short>
<descr>
<p>
<var>EditKeyDown</var> is an overridden method in <var>TTreeFilterEdit</var>.
It extends the inherited method to ensure that key strokes in the Edit for the
control are applied (when needed) to its FilteredTreeview control.
</p>
<p>
When FilteredTreeview has been assigned in the control, the following values
in Key and Shift are handled:
</p>
<dl>
<dt>Alt+Left, Alt+Right</dt>
<dd>
Moves the selection in the associated tree view. Extends the selected cells in
the associated tree view when the option is enabled in the MultiSelectionStyle
for the tree view control.
</dd>
<dt>Shift+Alt+Left</dt>
<dd>
Collapses all of the tree nodes in the FilteredTreeview control.
</dd>
<dt>Shift+Alt+Right</dt>
<dd>
Expands all of the tree nodes in the FilteredTreeview control.
</dd>
</dl>
<p>
The value in Key is set to 0 if it was forward handled using methods in the
tree view control.
</p>
<p>
If Key has a value that is not handled in the method, or FilteredTreeview is
unassigned, the inherited method is called to handle the key combination for
the control.
</p>
</descr>
<version>
Added in LazControls version 2.4.0.
