Widget that displays any object that implements the [iface@Gtk.TreeModel] interface.

Please refer to the [tree widget conceptual overview](section-tree-widget.html)
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 `GtkTreeView` API.
These are:

![](tree-view-coordinates.png)

- 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 [method@Gtk.TreeView.convert_widget_to_bin_window_coords]
(and vice versa), for the latter [method@Gtk.TreeView.convert_bin_window_to_tree_coords]
(and vice versa).

## `GtkTreeView` as `GtkBuildable`

The `GtkTreeView` implementation of the `GtkBuildable` interface accepts
[class@Gtk.TreeViewColumn] objects as `<child>` elements and exposes the
internal [class@Gtk.TreeSelection] in UI definitions.

An example of a UI definition fragment with `GtkTreeView`:

```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

```
treeview.view
├── header
│ ├── button
│ │ ╰── [sort-indicator]
┊ ┊
│ ╰── button
│ ╰── [sort-indicator]
│
├── [rubberband]
╰── [dndtarget]
```

`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.

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.

      Veraltet.
      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
      %NULL, 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 %NULL, 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.
      Parameter:

      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
      %NULL, or points to a path not currently displayed, the @y and @height fields
      of the rectangle will be filled with 0. If @column is %NULL, the @x and @width
      fields will be filled with 0. The sum of all cell rects does not cover the
      entire tree; there are extra pixels in between rows, for example. The
      returned rectangle is equivalent to the @cell_area passed to
      gtk_cell_renderer_render(). This function is only valid if @tree_view is
      realized.
      Parameter:
      path - a `GtkTreePath` for the row, or %NULL to get only horizontal coordinates
      column - a `GtkTreeViewColumn` for the column, or %NULL to get only vertical coordinates
      rect - rectangle to fill with cell rect

    • rowActivated

      @Deprecated public void rowActivated(@Nonnull TreePath path, @Nullable TreeViewColumn column)
      Veraltet.
      Activates the cell determined by @path and @column.
      Parameter:
      path - The `GtkTreePath` to be activated.
      column - The `GtkTreeViewColumn` to be activated.

    • rowExpanded

      @Deprecated public boolean rowExpanded(@Nonnull TreePath path)
      Veraltet.
      Returns %TRUE if the node pointed to by @path is expanded in @tree_view.
      Parameter:
      path - A `GtkTreePath` to test expansion state.
      Gibt zurück:
      %TRUE if #path is expanded.

    • scrollToCell

      @Deprecated public void scrollToCell(@Nullable TreePath path, @Nullable TreeViewColumn column, boolean use_align, float row_align, float col_align)
      Veraltet.
      Moves the alignments of @tree_view to the position specified by @column and
      @path. If @column is %NULL, then no horizontal scrolling occurs. Likewise,
      if @path is %NULL no vertical scrolling occurs. At a minimum, one of @column
      or @path need to be non-%NULL. @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.

      If @use_align is %FALSE, then the alignment arguments are ignored, and the
      tree does the minimum amount of work to scroll the cell onto the screen.
      This means that the cell will be scrolled to the edge closest to its current
      position. If the cell is currently visible on the screen, nothing is done.

      This function only works if the model is set, and @path is a valid row on the
      model. If the model changes before the @tree_view is realized, the centered
      path will be modified to reflect this change.
      Parameter:
      path - The path of the row to move to
      column - The `GtkTreeViewColumn` to move horizontally to
      use_align - whether to use alignment arguments, or %FALSE.
      row_align - The vertical alignment of the row specified by @path.
      col_align - The horizontal alignment of the column specified by @column.

    • scrollToPoint

      @Deprecated public void scrollToPoint(int tree_x, int tree_y)
      Veraltet.
      Scrolls the tree view such that the top-left corner of the visible
      area is @tree_x, @tree_y, where @tree_x and @tree_y are specified
      in tree coordinates. The @tree_view must be realized before
      this function is called. If it isn't, you probably want to be
      using gtk_tree_view_scroll_to_cell().

      If either @tree_x or @tree_y are -1, then that direction isn’t scrolled.
      Parameter:
      tree_x - X coordinate of new top-left pixel of visible area, or -1
      tree_y - Y coordinate of new top-left pixel of visible area, or -1

    • setActivateOnSingleClick

      @Deprecated public void setActivateOnSingleClick(boolean single)
      Veraltet.
      Cause the `GtkTreeView`::row-activated signal to be emitted
      on a single click instead of a double click.
      Parameter:
      single - %TRUE to emit row-activated on a single click

    • setColumnDragFunction

      @Deprecated public void setColumnDragFunction(TreeView.OnTreeViewColumnDropFunc func, @Nullable Pointer user_data, TreeView.OnDestroyNotify destroy)
      Veraltet.
      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 @tree_view, the `GtkTreeViewColumn` being
      dragged, the two `GtkTreeViewColumn`s determining the drop spot, and
      @user_data. If either of the `GtkTreeViewColumn` arguments for the drop spot
      are %NULL, then they indicate an edge. If @func is set to be %NULL, then
      @tree_view reverts to the default behavior of allowing all columns to be
      dropped everywhere.
      Parameter:
      func - A function to determine which columns are reorderable
      user_data - User data to be passed to @func
      destroy - Destroy notifier for @user_data

    • setCursor

      @Deprecated public void setCursor(@Nonnull TreePath path, @Nullable TreeViewColumn focus_column, boolean start_editing)
      Veraltet.
      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 %NULL, 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 (@tree_view)
      in order to give keyboard focus to the widget. Please note that editing
      can only happen when the widget is realized.

      If @path is invalid for @model, the current cursor (if any) will be unset
      and the function will return without failing.
      Parameter:
      path - A `GtkTreePath`
      focus_column - A `GtkTreeViewColumn`
      start_editing - %TRUE if the specified cell should start being edited.

      Veraltet.
      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 %NULL, then focus is given to the column specified by
      it. If @focus_column and @focus_cell are not %NULL, 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 (@tree_view) in order to give keyboard focus to the
      widget. Please note that editing can only happen when the widget is
      realized.

      If @path is invalid for @model, the current cursor (if any) will be unset
      and the function will return without failing.
      Parameter:
      path - A `GtkTreePath`
      focus_column - A `GtkTreeViewColumn`
      focus_cell - A `GtkCellRenderer`
      start_editing - %TRUE if the specified cell should start being edited.

      pos - Specifies whether to drop before, after or into the row

    • setEnableSearch

      @Deprecated public void setEnableSearch(boolean enable_search)
      Veraltet.
      If @enable_search is set, then the user can type in text to search through
      the tree interactively (this is sometimes called "typeahead find").

      Note that even if this is %FALSE, the user can still initiate a search
      using the “start-interactive-search” key binding.
      Parameter:
      enable_search - %TRUE, if the user can search interactively

    • setEnableTreeLines

      @Deprecated public void setEnableTreeLines(boolean enabled)
      Veraltet.
      Sets whether to draw lines interconnecting the expanders in @tree_view.
      This does not have any visible effects for lists.
      Parameter:
      enabled - %TRUE to enable tree line drawing, %FALSE otherwise.

    • setExpanderColumn

      @Deprecated public void setExpanderColumn(@Nullable TreeViewColumn column)
      Veraltet.
      Sets the column to draw the expander arrow at. It must be in @tree_view.
      If @column is %NULL, then the expander arrow is always at the first
      visible column.

      If you do not want expander arrow to appear in your tree, set the
      expander column to a hidden column.
      Parameter:
      column - %NULL, or the column to draw the expander arrow at.

    • setFixedHeightMode

      @Deprecated public void setFixedHeightMode(boolean enable)
      Veraltet.
      Enables or disables the fixed height mode of @tree_view.
      Fixed height mode speeds up `GtkTreeView` by assuming that all
      rows have the same height.
      Only enable this option if all rows are the same height and all
      columns are of type %GTK_TREE_VIEW_COLUMN_FIXED.
      Parameter:

      Hover expansion makes rows expand or collapse if the pointer
      moves over them.
      Parameter:
      expand - %TRUE to enable hover selection mode

    • setHoverSelection

      @Deprecated public void setHoverSelection(boolean hover)
      Veraltet.
      Enables or disables the hover selection mode of @tree_view.
      Hover selection makes the selected row follow the pointer.
      Currently, this works only for the selection modes
      %GTK_SELECTION_SINGLE and %GTK_SELECTION_BROWSE.
      Parameter:
      hover - %TRUE to enable hover selection mode

    • setLevelIndentation

      @Deprecated public void setLevelIndentation(int indentation)
      Veraltet.
      Sets the amount of extra indentation for child levels to use in @tree_view
      in addition to the default indentation. The value should be specified in
      pixels, a value of 0 disables this feature and in this case only the default
      indentation will be used.
      This does not have any visible effects for lists.
      Parameter:
      indentation - the amount, in pixels, of extra indentation in @tree_view.

    • setModel

      @Deprecated public void setModel(@Nullable TreeModel model)
      Veraltet.
      Sets the model for a `GtkTreeView`. If the @tree_view already has a model
      set, it will remove it before setting the new model. If @model is %NULL,
      then it will unset the old model.
      Parameter:
      model - The model.

    • setReorderable

      @Deprecated public void setReorderable(boolean reorderable)
      Veraltet.
      This function is a convenience function to allow you to reorder
      models that support the `GtkTreeDragSourceIface` and the
      `GtkTreeDragDestIface`. Both `GtkTreeStore` and `GtkListStore` 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.

      This function does not give you any degree of control over the order -- any
      reordering is allowed. If more control is needed, you should probably
      handle drag and drop manually.
      Parameter:
      reorderable - %TRUE, if the tree can be reordered.

    • setRowSeparatorFunc

      @Deprecated public void setRowSeparatorFunc(TreeView.OnTreeViewRowSeparatorFunc func, @Nullable Pointer data, TreeView.OnDestroyNotify destroy)
      Veraltet.
      Sets the row separator function, which is used to determine
      whether a row should be drawn as a separator. If the row separator
      function is %NULL, no separators are drawn. This is the default value.
      Parameter:
      func - a `GtkTreeView`RowSeparatorFunc
      data - user data to pass to @func
      destroy - destroy notifier for @data

    • setRubberBanding

      @Deprecated public void setRubberBanding(boolean enable)
      Veraltet.
      Enables or disables rubber banding in @tree_view. If the selection mode
      is %GTK_SELECTION_MULTIPLE, rubber banding will allow the user to select
      multiple rows by dragging the mouse.
      Parameter:
      enable - %TRUE to enable rubber banding

    • setSearchColumn

      @Deprecated public void setSearchColumn(int column)
      Veraltet.
      Sets @column as the column where the interactive search code should
      search in for the current model.

      If the search column is set, users can use the “start-interactive-search”
      key binding to bring up search popup. The enable-search property controls
      whether simply typing text will also start an interactive search.

      Note that @column refers to a column of the current model. The search
      column is reset to -1 when the model is changed.
      Parameter:
      column - the column of the model to search in, or -1 to disable searching

    • setSearchEntry

      @Deprecated public void setSearchEntry(@Nullable Editable entry)
      Veraltet.
      Sets the entry which the interactive search code will use for this
      @tree_view. This is useful when you want to provide a search entry
      in our interface at all time at a fixed position. Passing %NULL for
      @entry will make the interactive search code use the built-in popup
      entry again.
      Parameter:
      entry - the entry the interactive search code of @tree_view should use

    • setSearchEqualFunc

      @Deprecated public void setSearchEqualFunc(TreeView.OnTreeViewSearchEqualFunc search_equal_func, @Nullable Pointer search_user_data, TreeView.OnDestroyNotify search_destroy)
      Veraltet.
      Sets the compare function for the interactive search capabilities; note
      that somewhat like strcmp() returning 0 for equality
      `GtkTreeView`SearchEqualFunc returns %FALSE on matches.
      Parameter:
      search_equal_func - the compare function to use during the search
      search_user_data - user data to pass to @search_equal_func
      search_destroy - Destroy notifier for @search_user_data

    • setShowExpanders

      @Deprecated public void setShowExpanders(boolean enabled)
      Veraltet.
      Sets whether to draw and enable expanders and indent child rows in
      @tree_view. 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.
      Parameter:
      enabled - %TRUE to enable expander drawing, %FALSE otherwise.

    • setTooltipCell

      @Deprecated public void setTooltipCell(@Nonnull Tooltip tooltip, @Nullable TreePath path, @Nullable TreeViewColumn column, @Nullable CellRenderer cell)
      Veraltet.
      Sets the tip area of @tooltip to the area @path, @column and @cell have
      in common. For example if @path is %NULL and @column is set, the tip
      area will be set to the full area covered by @column. See also
      gtk_tooltip_set_tip_area().

      Note that if @path is not specified and @cell is set and part of a column
      containing the expander, the tooltip might not show and hide at the correct
      position. In such cases @path must be set to the current node under the
      mouse cursor for this function to operate correctly.

      See also gtk_tree_view_set_tooltip_column() for a simpler alternative.
      Parameter:
      tooltip - a `GtkTooltip`
      path - a `GtkTreePath`
      column - a `GtkTreeViewColumn`
      cell - a `GtkCellRenderer`

    • setTooltipColumn

      @Deprecated public void setTooltipColumn(int column)
      Veraltet.
      If you only plan to have simple (text-only) tooltips on full rows, you
      can use this function to have `GtkTreeView` handle these automatically
      for you. @column should be set to the column in @tree_view’s model
      containing the tooltip texts, or -1 to disable this feature.

      When enabled, `GtkWidget:has-tooltip` will be set to %TRUE and
      @tree_view will connect a `GtkWidget::query-tooltip` signal handler.

      Note that the signal handler sets the text with gtk_tooltip_set_markup(),
      so &, <, etc have to be escaped in the text.
      Parameter:
      column - an integer, which is a valid column number for @tree_view’s model

    • setTooltipRow

      @Deprecated public void setTooltipRow(@Nonnull Tooltip tooltip, @Nonnull TreePath path)
      Veraltet.
      Sets the tip area of @tooltip to be the area covered by the row at @path.
      See also gtk_tree_view_set_tooltip_column() for a simpler alternative.
      See also gtk_tooltip_set_tip_area().
      Parameter:
      tooltip - a `GtkTooltip`
      path - a `GtkTreePath`

    • unsetRowsDragDest

      @Deprecated public void unsetRowsDragDest()
      Veraltet.
