Struct gtk::TreeView

#[repr(transparent)]
pub struct TreeView { /* private fields */ }

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 xml ⚠️

<object class="GtkTreeView" id="treeview">
  <property name="model">liststore1</property>
  <child>
    <object class="GtkTreeViewColumn" id="test-column">
      <property name="title">Test</property>
      <child>
        <object class="GtkCellRendererText" id="test-renderer"/>
        <attributes>
          <attribute name="text">1</attribute>
        </attributes>
      </child>
    </object>
  </child>
  <child internal-child="selection">
    <object class="GtkTreeSelection" id="selection">
      <signal name="changed" handler="on_treeview_selection_changed"/>
    </object>
  </child>
</object>

CSS nodes

⚠️ 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

impl TreeView

pub const NONE: Option<&'static TreeView> = None

pub fn new() -> TreeView

Creates a new TreeView widget.

Returns

A newly created TreeView widget.

pub fn with_model(model: &impl IsA<TreeModel>) -> TreeView

Creates a new TreeView widget with the model initialized to model.

model

the model.

Returns

A newly created TreeView widget.

pub fn builder() -> TreeViewBuilder

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

impl Clone for TreeView

fn clone(&self) -> Self

Returns a copy of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TreeView

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TreeView

fn default() -> Self

Returns the “default value” for a type.

impl Display for TreeView

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for TreeView

fn hash<H>(&self, state: &mut H)where
    H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl<T: ContainerImpl> IsSubclassable<T> for TreeView

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for TreeView

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for TreeView

type Parent = Container

impl<OT: ObjectType> PartialEq<OT> for TreeView

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for TreeView

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

const fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

const fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

const fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

const fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for TreeView

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for TreeView

impl IsA<Buildable> for TreeView

impl IsA<Container> for TreeView

impl IsA<Scrollable> for TreeView
