Expand description

Use ListView for lists, and ColumnView for tabular lists A widget for displaying both trees and lists

Widget that displays any object that implements the TreeModel interface.

Please refer to the tree widget conceptual overview for an overview of all the objects and data types related to the tree widget and how they work together.

Coordinate systems in GtkTreeView API

Several different coordinate systems are exposed in the TreeView API. These are:

  • 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).

TreeView as Buildable

The TreeView implementation of the Buildable interface accepts TreeViewColumn objects as <child> elements and exposes the internal TreeSelection in UI definitions.

An example of a UI definition fragment with TreeView:

<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>

TreeView 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.

Each column header consists of a button, which among other content, has a child with name sort-indicator, which carries the .ascending or .descending style classes when the column header should show a sort indicator. The CSS is expected to provide a suitable image using the -gtk-icon-source property.

For rubberband selection, a subnode with name rubberband is used.

For the drop target location during DND, a subnode with name dndtarget is used.

Properties

activate-on-single-click

The activate-on-single-click property specifies whether the “row-activated” signal will be emitted after a single click.

Signals

columns-changed

The number of columns of the treeview has changed.

cursor-changed

The position of the cursor (focused cell) has changed.

expand-collapse-cursor-row

Action

move-cursor

The TreeView::move-cursor signal is a [keybinding signal]SignalAction which gets emitted when the user presses one of the cursor keys.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control the cursor programmatically. In contrast to gtk_tree_view_set_cursor() and gtk_tree_view_set_cursor_on_cell() when moving horizontally TreeView::move-cursor does not reset the current selection.

Action

row-activated

The “row-activated” signal is emitted when the method TreeViewExt::row_activated() is called.

This signal is emitted when the user double-clicks a treeview row with the activate-on-single-click property set to false, or when the user single-clicks a row when that property set to true.

This signal is also emitted when a non-editable row is selected and one of the keys: Space, Shift+Space, Return or Enter is pressed.

For selection handling refer to the tree widget conceptual overview as well as TreeSelection.

Action

row-collapsed

The given row has been collapsed (child nodes are hidden).

row-expanded

The given row has been expanded (child nodes are shown).

select-all

Action

select-cursor-parent

Action

select-cursor-row

Action

Action

test-collapse-row

The given row is about to be collapsed (hide its children nodes). Use this signal if you need to control the collapsibility of individual rows.

test-expand-row

The given row is about to be expanded (show its children nodes). Use this signal if you need to control the expandability of individual rows.

toggle-cursor-row

Action

unselect-all

Action

Widget

destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

direction-changed

Emitted when the text direction of a widget changes.

hide

Emitted when @widget is hidden.

keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering “above” @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

show

Emitted when @widget is shown.

state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).

fn background_area( &self, path: Option<&TreePath>, column: Option<&TreeViewColumn> ) -> Rectangle

👎Deprecated: Since 4.10
Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by @path and the column specified by @column. If @path is None, or points to a node not found in the tree, the @y and @height fields of the rectangle will be filled with 0. If @column is None, the @x and @width fields will be filled with 0. The returned rectangle is equivalent to the @background_area passed to gtk_cell_renderer_render(). These background areas tile to cover the entire bin window. Contrast with the @cell_area, returned by gtk_tree_view_get_cell_area(), which returns only the cell itself, excluding surrounding borders and the tree expander area. Read more
source§

fn cell_area( &self, path: Option<&TreePath>, column: Option<&TreeViewColumn> ) -> Rectangle

👎Deprecated: Since 4.10

fn path_at_pos( &self, x: i32, y: i32 ) -> Option<(Option<TreePath>, Option<TreeViewColumn>, i32, i32)>

👎Deprecated: Since 4.10
Finds the path at the point (@x, @y), relative to bin_window coordinates. That is, @x and @y are relative to an events coordinates. Widget-relative coordinates must be converted using gtk_tree_view_convert_widget_to_bin_window_coords(). It is primarily for things like popup menus. If @path is non-None, then it will be filled with the TreePath at that point. This path should be freed with gtk_tree_path_free(). If @column is non-None, then it will be filled with the column at that point. @cell_x and @cell_y return the coordinates relative to the cell background (i.e. the @background_area passed to gtk_cell_renderer_render()). This function is only meaningful if @self is realized. Therefore this function will always return false if @self is not realized or does not have a model. Read more

fn scroll_to_cell( &self, path: Option<&TreePath>, column: Option<&TreeViewColumn>, use_align: bool, row_align: f32, col_align: f32 )

👎Deprecated: Since 4.10
Moves the alignments of @self to the position specified by @column and @path. If @column is None, then no horizontal scrolling occurs. Likewise, if @path is None no vertical scrolling occurs. At a minimum, one of @column or @path need to be non-None. @row_align determines where the row is placed, and @col_align determines where @column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center. Read more

fn set_column_drag_function( &self, func: Option<Box_<dyn Fn(&TreeView, &TreeViewColumn, &TreeViewColumn, &TreeViewColumn) -> bool + 'static>> )

👎Deprecated: Since 4.10
Sets a user function for determining where a column may be dropped when dragged. This function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. The arguments passed to @func are: the @self, the TreeViewColumn being dragged, the two TreeViewColumns determining the drop spot, and @user_data. If either of the TreeViewColumn arguments for the drop spot are None, then they indicate an edge. If @func is set to be None, then @self reverts to the default behavior of allowing all columns to be dropped everywhere. Read more
source§

fn set_cursor( &self, path: &TreePath, focus_column: Option<&TreeViewColumn>, start_editing: bool )

👎Deprecated: Since 4.10
Sets the current keyboard focus to be at @path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If @focus_column is not None, then focus is given to the column specified by it. Additionally, if @focus_column is specified, and @start_editing is true, then editing should be started in the specified cell. This function is often followed by @gtk_widget_grab_focus (@self) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized. Read more
source§

fn set_cursor_on_cell( &self, path: &TreePath, focus_column: Option<&TreeViewColumn>, focus_cell: Option<&impl IsA<CellRenderer>>, start_editing: bool )

👎Deprecated: Since 4.10
Sets the current keyboard focus to be at @path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If @focus_column is not None, then focus is given to the column specified by it. If @focus_column and @focus_cell are not None, and @focus_column contains 2 or more editable or activatable cells, then focus is given to the cell specified by @focus_cell. Additionally, if @focus_column is specified, and @start_editing is true, then editing should be started in the specified cell. This function is often followed by @gtk_widget_grab_focus (@self) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized. Read more

fn set_model(&self, model: Option<&impl IsA<TreeModel>>)

👎Deprecated: Since 4.10
Sets the model for a TreeView. If the @self already has a model set, it will remove it before setting the new model. If @model is None, then it will unset the old model. Read more
source§

fn set_reorderable(&self, reorderable: bool)

👎Deprecated: Since 4.10
This function is a convenience function to allow you to reorder models that support the GtkTreeDragSourceIface and the GtkTreeDragDestIface. Both TreeStore and ListStore support these. If @reorderable is true, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model’s GtkTreeModel::row-inserted and GtkTreeModel::row-deleted signals. The reordering is implemented by setting up the tree view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose. Read more
source§

fn set_row_separator_func<P: Fn(&TreeModel, &TreeIter) -> bool + 'static>( &self, func: P )

source§

fn set_show_expanders(&self, enabled: bool)

👎Deprecated: Since 4.10
Sets whether to draw and enable expanders and indent child rows in @self. When disabled there will be no expanders visible in trees and there will be no way to expand and collapse rows by default. Also note that hiding the expanders will disable the default indentation. You can set a custom indentation in this case using gtk_tree_view_set_level_indentation(). This does not have any visible effects for lists. Read more
source§

fn set_tooltip_cell( &self, tooltip: &Tooltip, path: Option<&TreePath>, column: Option<&TreeViewColumn>, cell: Option<&impl IsA<CellRenderer>> )

👎Deprecated: Since 4.10

source§

fn set_tooltip_column(&self, column: i32)

👎Deprecated: Since 4.10
If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have TreeView handle these automatically for you. @column should be set to the column in @self’s model containing the tooltip texts, or -1 to disable this feature. Read more
source§

fn set_tooltip_row(&self, tooltip: &Tooltip, path: &TreePath)
