Returns the number of rows that have been selected in tree.
Gets the selection mode for selection. See gtk.tree_selection.TreeSelection.setMode.
Sets iter to the currently selected node if selection is set to gtk.types.SelectionMode.Single or gtk.types.SelectionMode.Browse. iter may be NULL if you just want to test if selection has any selected nodes. model is filled with the current model as a convenience. This function will not work if you use selection is gtk.types.SelectionMode.Multiple.
Creates a list of path of all selected rows. Additionally, if you are planning on modifying the model after calling this function, you may want to convert the returned list into a list of gtk.tree_row_reference.TreeRowReferences. To do this, you can use gtk.tree_row_reference.TreeRowReference.new_.
Returns the tree view associated with selection.
Returns true if the row at iter is currently selected.
Returns true if the row pointed to by path is currently selected. If path does not point to a valid location, false is returned
Selects all the nodes. selection must be set to gtk.types.SelectionMode.Multiple mode.
Selects the specified iterator.
Select the row at path.
Selects a range of nodes, determined by start_path and end_path inclusive. selection must be set to gtk.types.SelectionMode.Multiple mode.
Calls a function for each selected node. Note that you cannot modify the tree or selection from within this function. As a result, gtk.tree_selection.TreeSelection.getSelectedRows might be more useful.
Sets the selection mode of the selection. If the previous type was gtk.types.SelectionMode.Multiple, then the anchor is kept selected, if it was previously selected.
Sets the selection function.
Unselects all the nodes.
Unselects the specified iterator.
Unselects the row at path.
Unselects a range of nodes, determined by start_path and end_path inclusive.
Set the GObject of a D ObjectG wrapper.
Get a pointer to the underlying C object.
Calls g_object_ref() on a GObject.
Calls g_object_unref() on a GObject.
Get the GType of an object.
GObject GType property.
Convenience method to return this cast to a type. For use in D with statements.
Template to get the D object from a C GObject and cast it to the given D object type.
Connect a D closure to an object signal.
Template for setting a GObject property.
Template for getting a GObject property.
Creates a binding between source_property on source and target_property on target.
Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.
This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectG.refSink.
Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
Gets a named field from the objects table of associations (see gobject.object.ObjectG.setData).
Gets a property of an object.
This function gets back user data pointers stored via gobject.object.ObjectG.setQdata.
Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
Checks whether object has a floating[floating-ref] reference.
Emits a "notify" signal for the property property_name on object.
Emits a "notify" signal for the property specified by pspec on object.
Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.
Releases all references to other objects. This can be used to break reference cycles.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
Sets a property on an object.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
This function gets back user data pointers stored via gobject.object.ObjectG.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:
Reverts the effect of a previous call to gobject.object.ObjectG.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.
This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectG.ref_ and gobject.object.ObjectG.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

The selection object for GtkTreeView
The gtk.tree_selection.TreeSelection object is a helper object to manage the selection for a gtk.tree_view.TreeView widget. The gtk.tree_selection.TreeSelection object is automatically created when a new gtk.tree_view.TreeView widget is created, and cannot exist independently of this widget. The primary reason the gtk.tree_selection.TreeSelection objects exists is for cleanliness of code and API. That is, there is no conceptual reason all these functions could not be methods on the gtk.tree_view.TreeView widget instead of a separate function.
The gtk.tree_selection.TreeSelection object is gotten from a gtk.tree_view.TreeView by calling gtk.tree_view.TreeView.getSelection. It can be manipulated to check the selection status of the tree, as well as select and deselect individual rows. Selection is done completely view side. As a result, multiple views of the same model can have completely different selections. Additionally, you cannot change the selection of a row on the model that is not currently displayed by the view without expanding its parents first.
One of the important things to remember when monitoring the selection of a view is that the gtk.tree_selection.TreeSelection::changed signal is mostly a hint. That is, it may only emit one signal when a range of rows is selected. Additionally, it may on occasion emit a gtk.tree_selection.TreeSelection::changed signal when nothing has happened (mostly as a result of programmers calling select_row on an already selected row).
