<summary>The selection object for <see cref="T:Gtk.TreeView" />.</summary>
|
|
<remarks>
|
|
<para>TreeSelection provides a single class for managing selection information on the List/Tree widget.</para>
|
|
<para>A TreeSelection object is automatically created when a new <see cref="T:Gtk.TreeView" /> widget is created and is inherently tied to it. A TreeSelection cannot exist independently of a <see cref="T:Gtk.TreeView" />. Selection information is retrieved from the <see cref="T:Gtk.TreeView" /> with the <see cref="P:Gtk.TreeView.Selection" /> property.</para>
|
|
<para>TreeSelection can check the selection status of the tree, as well as select and deselect individual rows. Selection is done completely on the view. As a result, multiple views of the same model can have completely different selections. Additionally, you cannot change the selection of a row that is not currently displayed by the view without expanding its parents first.</para>
|
|
<para>One of the important things to remember when monitoring the selection of a view is that the <see cref="E:Gtk.TreeSelection.Changed" /> event is mostly a hint. For example, it may only fire once when a range of rows is selected. It may also fire when nothing has happened, such as when <see cref="M:Gtk.TreeSelection.SelectPath(Gtk.TreePath)" /> is called on a row that is already selected.</para>
