Struct gtk::TreeView [−][src]
pub struct TreeView(_);
Expand description
Widget that displays any object that implements the TreeModel
interface.
Please refer to the [tree widget conceptual overview][TreeWidget] for an overview of all the objects and data types related to the tree widget and how they work together.
Several different coordinate systems are exposed in the GtkTreeView API. These are:
Coordinate systems in GtkTreeView API:
-
Widget coordinates: Coordinates relative to the widget (usually
widget->window
). -
Bin window coordinates: Coordinates relative to the window that GtkTreeView renders to.
-
Tree coordinates: Coordinates relative to the entire scrollable area of GtkTreeView. These coordinates start at (0, 0) for row 0 of the tree.
Several functions are available for converting between the different
coordinate systems. The most common translations are between widget and bin
window coordinates and between bin window and tree coordinates. For the
former you can use TreeViewExt::convert_widget_to_bin_window_coords()
(and vice versa), for the latter TreeViewExt::convert_bin_window_to_tree_coords()
(and vice versa).
GtkTreeView as GtkBuildable
The GtkTreeView implementation of the GtkBuildable interface accepts
TreeViewColumn
objects as <child>
elements and exposes the internal
TreeSelection
in UI definitions.
An example of a UI definition fragment with GtkTreeView:
⚠️ The following code is in plain ⚠️
treeview.view
├── header
│ ├── <column header>
┊ ┊
│ ╰── <column header>
│
╰── [rubberband]
GtkTreeView has a main CSS node with name treeview and style class .view. It has a subnode with name header, which is the parent for all the column header widgets’ CSS nodes. For rubberband selection, a subnode with name rubberband is used.

Implementations
Creates a new builder-pattern struct instance to construct TreeView
objects.
This method returns an instance of TreeViewBuilder
which can be used to create TreeView
objects.
Trait Implementations
This method returns an ordering between self
and other
values if one exists. Read more
This method tests less than (for self
and other
) and is used by the <
operator. Read more
This method tests less than or equal to (for self
and other
) and is used by the <=
operator. Read more

Tries to cast to an object of type T
. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast
and upcast
will do many checks at compile-time already. Read more
