### Class

# GtkTreeView

deprecated: 4.10

#### Description [src]

    class Gtk.TreeView : Gtk.Widget {
      parent_instance: GtkWidget
    }

A widget for displaying both trees and lists

Widget that displays any object that implements the `GtkTreeModel` 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 `GtkTreeView` 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 `gtk_tree_view_convert_widget_to_bin_window_coords()` (and vice versa), for the latter `gtk_tree_view_convert_bin_window_to_tree_coords()` (and vice versa).

## `GtkTreeView` as `GtkBuildable`

The `GtkTreeView` implementation of the `GtkBuildable` interface accepts `GtkTreeViewColumn` objects as `<child>` elements and exposes the internal `GtkTreeSelection` in UI definitions.

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

    <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.

Deprecated since: 4.10

Use `GtkListView` for lists, and `GtkColumnView` for tabular lists.

Converts widget coordinates to coordinates for the tree (the full scrollable area of the tree).

deprecated: 4.10

###### gtk_tree_view_create_row_drag_icon

Creates a `cairo_surface_t` representation of the row at `path`. This image is used for a drag icon.

deprecated: 4.10

###### gtk_tree_view_enable_model_drag_dest

Turns `tree_view` into a drop destination for automatic DND. Calling this method sets `GtkTreeView`:reorderable to `FALSE`.

deprecated: 4.10

###### gtk_tree_view_enable_model_drag_source

Turns `tree_view` into a drag source for automatic DND. Calling this method sets `GtkTreeView`:reorderable to `FALSE`.

deprecated: 4.10

###### gtk_tree_view_expand_all

Recursively expands all nodes in the `tree_view`.

deprecated: 4.10

###### gtk_tree_view_expand_row

Opens the row so its children are visible.

deprecated: 4.10

###### gtk_tree_view_expand_to_path

Expands the row at `path`. This will also expand all parent rows of `path` as necessary.

deprecated: 4.10

###### gtk_tree_view_get_activate_on_single_click

Gets the setting set by gtk_tree_view_set_activate_on_single_click().

deprecated: 4.10

###### gtk_tree_view_get_background_area

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.

deprecated: 4.10

###### gtk_tree_view_get_cell_area

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.

deprecated: 4.10

###### gtk_tree_view_get_column

Gets the `GtkTreeViewColumn` at the given position in the #tree_view.

deprecated: 4.10

###### gtk_tree_view_get_columns

Returns a `GList` of all the `GtkTreeViewColumn`s currently in `tree_view`. The returned list must be freed with g_list_free ().

deprecated: 4.10

###### gtk_tree_view_get_cursor

Fills in `path` and `focus_column` with the current path and focus column. If the cursor isn’t currently set, then `path` will be `NULL`. If no column currently has focus, then `focus_column` will be `NULL`.

deprecated: 4.10

###### gtk_tree_view_get_dest_row_at_pos

Determines the destination row for a given position. `drag_x` and `drag_y` are expected to be in widget coordinates. This function is only meaningful if `tree_view` is realized. Therefore this function will always return `FALSE` if `tree_view` is not realized or does not have a model.

deprecated: 4.10

###### gtk_tree_view_get_drag_dest_row

Gets information about the row that is highlighted for feedback.

deprecated: 4.10

deprecated: 4.10

###### gtk_tree_view_get_enable_tree_lines

Returns whether or not tree lines are drawn in `tree_view`.

deprecated: 4.10

###### gtk_tree_view_get_expander_column

deprecated: 4.10

###### gtk_tree_view_get_fixed_height_mode

Returns whether fixed height mode is turned on for `tree_view`.

deprecated: 4.10

###### gtk_tree_view_get_grid_lines

deprecated: 4.10

###### gtk_tree_view_get_headers_clickable

Returns whether all header columns are clickable.

deprecated: 4.10

###### gtk_tree_view_get_headers_visible

Returns `TRUE` if the headers on the `tree_view` are visible.

deprecated: 4.10

###### gtk_tree_view_get_hover_expand

deprecated: 4.10

###### gtk_tree_view_get_level_indentation

Returns the amount, in pixels, of extra indentation for child levels in `tree_view`.

deprecated: 4.10

###### gtk_tree_view_get_model

Returns the model the `GtkTreeView` is based on. Returns `NULL` if the model is unset.

deprecated: 4.10

###### gtk_tree_view_get_n_columns

Queries the number of columns in the given `tree_view`.

deprecated: 4.10

###### gtk_tree_view_get_path_at_pos

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-`NULL`, then it will be filled with the `GtkTreePath` at that point. This path should be freed with gtk_tree_path_free(). If `column` is non-`NULL`, 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 `tree_view` is realized. Therefore this function will always return `FALSE` if `tree_view` is not realized or does not have a model.

deprecated: 4.10

###### gtk_tree_view_get_reorderable

Retrieves whether the user can reorder the tree via drag-and-drop. See gtk_tree_view_set_reorderable().

deprecated: 4.10

###### gtk_tree_view_get_row_separator_func

Returns the current row separator function.

deprecated: 4.10

###### gtk_tree_view_get_rubber_banding

Returns whether rubber banding is turned on for `tree_view`. If the selection mode is `GTK_SELECTION_MULTIPLE`, rubber banding will allow the user to select multiple rows by dragging the mouse.

deprecated: 4.10

###### gtk_tree_view_get_search_column

Gets the column searched on by the interactive search code.

deprecated: 4.10

###### gtk_tree_view_get_search_entry

Returns the `GtkEntry` which is currently in use as interactive search entry for `tree_view`. In case the built-in entry is being used, `NULL` will be returned.

deprecated: 4.10

###### gtk_tree_view_get_search_equal_func

Returns the compare function currently in use.

deprecated: 4.10

###### gtk_tree_view_get_selection

Gets the `GtkTreeSelection` associated with `tree_view`.

deprecated: 4.10

###### gtk_tree_view_get_show_expanders

Returns whether or not expanders are drawn in `tree_view`.

deprecated: 4.10

###### gtk_tree_view_get_tooltip_column

Returns the column of `tree_view`’s model which is being used for displaying tooltips on `tree_view`’s rows.

deprecated: 4.10

###### gtk_tree_view_get_tooltip_context

This function is supposed to be used in a ::query-tooltip signal handler for `GtkTreeView`. The `x`, `y` and `keyboard_tip` values which are received in the signal handler, should be passed to this function without modification.

deprecated: 4.10

###### gtk_tree_view_get_visible_range

Sets `start_path` and `end_path` to be the first and last visible path. Note that there may be invisible paths in between.

deprecated: 4.10

###### gtk_tree_view_get_visible_rect

Fills `visible_rect` with the currently-visible region of the buffer, in tree coordinates. Convert to bin_window coordinates with gtk_tree_view_convert_tree_to_bin_window_coords(). Tree coordinates start at 0,0 for row 0 of the tree, and cover the entire scrollable area of the tree.

deprecated: 4.10

###### gtk_tree_view_insert_column

This inserts the `column` into the `tree_view` at `position`. If `position` is -1, then the column is inserted at the end. If `tree_view` has “fixed_height” mode enabled, then `column` must have its “sizing” property set to be GTK_TREE_VIEW_COLUMN_FIXED.

deprecated: 4.10

###### gtk_tree_view_insert_column_with_attributes

Creates a new `GtkTreeViewColumn` and inserts it into the `tree_view` at `position`. If `position` is -1, then the newly created column is inserted at the end. The column is initialized with the attributes given. If `tree_view` has “fixed_height” mode enabled, then the new column will have its sizing property set to be GTK_TREE_VIEW_COLUMN_FIXED.

deprecated: 4.10

###### gtk_tree_view_insert_column_with_data_func

Convenience function that inserts a new column into the `GtkTreeView` with the given cell renderer and a `GtkTreeCellDataFunc` to set cell renderer attributes (normally using data from the model). See also gtk_tree_view_column_set_cell_data_func(), gtk_tree_view_column_pack_start(). If `tree_view` has “fixed_height” mode enabled, then the new column will have its “sizing” property set to be GTK_TREE_VIEW_COLUMN_FIXED.

deprecated: 4.10

###### gtk_tree_view_is_blank_at_pos

Determine whether the point (`x`, `y`) in `tree_view` is blank, that is no cell content nor an expander arrow is drawn at the location. If so, the location can be considered as the background. You might wish to take special action on clicks on the background, such as clearing a current selection, having a custom context menu or starting rubber banding.

deprecated: 4.10

###### gtk_tree_view_is_rubber_banding_active

Returns whether a rubber banding operation is currently being done in `tree_view`.

deprecated: 4.10

###### gtk_tree_view_map_expanded_rows

Calls `func` on all expanded rows.

deprecated: 4.10

###### gtk_tree_view_move_column_after

Moves `column` to be after to `base_column`. If `base_column` is `NULL`, then `column` is placed in the first position.

deprecated: 4.10

###### gtk_tree_view_remove_column

Removes `column` from `tree_view`.

deprecated: 4.10

###### gtk_tree_view_row_activated

Activates the cell determined by `path` and `column`.

deprecated: 4.10

###### gtk_tree_view_row_expanded

Returns `TRUE` if the node pointed to by `path` is expanded in `tree_view`.

deprecated: 4.10

###### gtk_tree_view_scroll_to_cell

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.

deprecated: 4.10

###### gtk_tree_view_scroll_to_point

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().

deprecated: 4.10

###### gtk_tree_view_set_activate_on_single_click

Cause the `GtkTreeView`::row-activated signal to be emitted on a single click instead of a double click.

deprecated: 4.10

###### gtk_tree_view_set_column_drag_function

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.

deprecated: 4.10

###### gtk_tree_view_set_cursor

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.

deprecated: 4.10

###### gtk_tree_view_set_cursor_on_cell

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.

deprecated: 4.10

###### gtk_tree_view_set_drag_dest_row

Sets the row that is highlighted for feedback. If `path` is `NULL`, an existing highlight is removed.

deprecated: 4.10

###### gtk_tree_view_set_enable_search

If `enable_search` is set, then the user can type in text to search through the tree interactively (this is sometimes called “typeahead find”).

deprecated: 4.10

###### gtk_tree_view_set_enable_tree_lines

Sets whether to draw lines interconnecting the expanders in `tree_view`. This does not have any visible effects for lists.

deprecated: 4.10

###### gtk_tree_view_set_expander_column

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.

deprecated: 4.10

###### gtk_tree_view_set_fixed_height_mode

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`.

deprecated: 4.10

###### gtk_tree_view_set_grid_lines

Sets which grid lines to draw in `tree_view`.

deprecated: 4.10

###### gtk_tree_view_set_headers_clickable

Allow the column title buttons to be clicked.

deprecated: 4.10

###### gtk_tree_view_set_headers_visible

Sets the visibility state of the headers.

deprecated: 4.10

###### gtk_tree_view_set_hover_expand

Enables or disables the hover expansion mode of `tree_view`. Hover expansion makes rows expand or collapse if the pointer moves over them.

deprecated: 4.10

###### gtk_tree_view_set_hover_selection

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`.

deprecated: 4.10

###### gtk_tree_view_set_level_indentation

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.

deprecated: 4.10

###### gtk_tree_view_set_model

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.

deprecated: 4.10

###### gtk_tree_view_set_reorderable

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.

deprecated: 4.10

###### gtk_tree_view_set_row_separator_func

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.

deprecated: 4.10

###### gtk_tree_view_set_rubber_banding

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.

deprecated: 4.10

###### gtk_tree_view_set_search_column

Sets `column` as the column where the interactive search code should search in for the current model.

deprecated: 4.10

###### gtk_tree_view_set_search_entry

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.

deprecated: 4.10

###### gtk_tree_view_set_search_equal_func

Sets the compare function for the interactive search capabilities; note that somewhat like `strcmp()` returning 0 for equality `GtkTreeView`SearchEqualFunc returns `FALSE` on matches.

deprecated: 4.10

###### gtk_tree_view_set_show_expanders

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.

deprecated: 4.10

###### gtk_tree_view_set_tooltip_cell

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().

deprecated: 4.10

###### gtk_tree_view_set_tooltip_column

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.

deprecated: 4.10

###### gtk_tree_view_set_tooltip_row

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().

deprecated: 4.10

###### gtk_tree_view_unset_rows_drag_dest

Undoes the effect of gtk_tree_view_enable_model_drag_dest(). Calling this method sets `GtkTreeView`:reorderable to `FALSE`.

deprecated: 4.10

###### gtk_tree_view_unset_rows_drag_source

Undoes the effect of gtk_tree_view_enable_model_drag_source(). Calling this method sets `GtkTreeView`:reorderable to `FALSE`.

deprecated: 4.10
