TreeView Signals</h2></div></div><div></div></div><p><tt class="classname">TreeView</tt>s emit a large number of signals
that you can use to track changes in the view of the model. The signals
generally fall into the following categories:</p><div class="itemizedlist"><ul type="disc"><li>expanding and collapsing rows: "row-collapsed",
"row-expanded", "test-collapse-row", "test-expand-row" and
"expand-collapse-cursor-row"</li><li>the cursor: "cursor-changed", "expand-collapse-cursor-row",
"move-cursor", "select-cursor-parent", "select-cursor-row" and
"toggle-cursor-row"</li><li>selection: "select-all", "select-cursor-parent",
"select-cursor-row" and "unselect-all".</li><li>miscellaneous: "columns-changed", "row-activated",
"set-scroll-adjustments" and "start-interactive-search".</li></ul></div><p>The "test-collapse-row" and "test-expand-row" signals are emitted
before a row is collapsed or expanded. The return value from your callback
can cancel or allow the operation - <tt class="literal">TRUE</tt> to allow and
<tt class="literal">FALSE</tt> to cancel.</p><table border="0" bgcolor="#E0E0E0" width="100%"><tr><td><pre class="programlisting">
def callback(treeview, iter, path, user_data)
</pre></td></tr></table><p>where <i class="parameter"><tt>iter</tt></i> is a
<tt class="classname">TreeIter</tt> and <i class="parameter"><tt>path</tt></i> is a tree
path pointing at the row and <i class="parameter"><tt>user_data</tt></i> is the data
specified in the <tt class="methodname">connect</tt>() method.</p><p>The "row-activated" signal is emitted when a double click occurs
on a row or a non-editable row is selected and one of the keys:
<span><b class="keycap">Space</b></span>, <span><b class="keycap">Shift</b></span>+<span><b class="keycap">Space</b></span>,
<span><b class="keycap">Return</b></span> or <span><b class="keycap">Enter</b></span> is pressed.</p><p>The rest of the signals are emitted after the
<tt class="classname">TreeView</tt> has changed. The cursor is the row outlined
by a box. In most cases moving the cursor also moves the selection. The
cursor can be moved independently by <span><b class="keycap">Control</b></span>+<span><b class="keycap">Down</b></span> or
<span><b class="keycap">Control</b></span>+<span><b class="keycap">Up</b></span> and various other key combinations.</p><p>See the <a href="http://www.pygtk.org/pygtk2reference/class-gtktreeview.html" target="_top">PyGTK
