TreeView

A widget for displaying both trees and lists

Widget that displays any object that implements the [iface@Gtk.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 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 [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:

<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>

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.

addOnUnselectAll gulong addOnUnselectAll(bool delegate(TreeView) dlg, ConnectFlags connectFlags)
appendColumn int appendColumn(TreeViewColumn column): Appends @column to the list of columns. If @tree_view has “fixed_height” mode enabled, then @column must have its “sizing” property set to be GTK_TREE_VIEW_COLUMN_FIXED.
collapseAll void collapseAll(): Recursively collapses all visible, expanded nodes in @tree_view.
collapseRow bool collapseRow(TreePath path): Collapses a row (hides its child rows, if they exist).
columnsAutosize void columnsAutosize(): Resizes all columns to their optimal width. Only works after the treeview has been realized.
convertBinWindowToTreeCoords void convertBinWindowToTreeCoords(int bx, int by, int tx, int ty): Converts bin_window coordinates to coordinates for the tree (the full scrollable area of the tree).
convertBinWindowToWidgetCoords void convertBinWindowToWidgetCoords(int bx, int by, int wx, int wy): Converts bin_window coordinates to widget relative coordinates.

createRowDragIcon PaintableIF createRowDragIcon(TreePath path): Creates a #cairo_surface_t representation of the row at @path. This image is used for a drag icon.
enableModelDragDest void enableModelDragDest(ContentFormats formats, GdkDragAction actions): Turns @tree_view into a drop destination for automatic DND. Calling this method sets #GtkTreeView:reorderable to %FALSE.
enableModelDragSource void enableModelDragSource(GdkModifierType startButtonMask, ContentFormats formats, GdkDragAction actions): Turns @tree_view into a drag source for automatic DND. Calling this method sets #GtkTreeView:reorderable to %FALSE.
expandAll void expandAll(): Recursively expands all nodes in the @tree_view.
expandRow bool expandRow(TreePath path, bool openAll): Opens the row so its children are visible.
expandToPath void expandToPath(TreePath path): Expands the row at @path. This will also expand all parent rows of @path as necessary.
getActivateOnSingleClick bool getActivateOnSingleClick(): Gets the setting set by gtk_tree_view_set_activate_on_single_click().
getBackgroundArea void getBackgroundArea(TreePath path, TreeViewColumn column, GdkRectangle rect): 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.
getCellArea void getCellArea(TreePath path, TreeViewColumn column, GdkRectangle rect): 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.
getColumn TreeViewColumn getColumn(int n): Gets the #GtkTreeViewColumn at the given position in the #tree_view.
getColumns ListG getColumns(): Returns a #GList of all the #GtkTreeViewColumn s currently in @tree_view. The returned list must be freed with g_list_free ().
getCursor void getCursor(TreePath path, TreeViewColumn focusColumn): 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.
getDestRowAtPos bool getDestRowAtPos(int dragX, int dragY, TreePath path, GtkTreeViewDropPosition 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.
getDragDestRow void getDragDestRow(TreePath path, GtkTreeViewDropPosition pos): Gets information about the row that is highlighted for feedback.
getEnableSearch bool getEnableSearch(): Returns whether or not the tree allows to start interactive searching by typing in text.
getEnableTreeLines bool getEnableTreeLines(): Returns whether or not tree lines are drawn in @tree_view.
getExpanderColumn TreeViewColumn getExpanderColumn(): Returns the column that is the current expander column, or %NULL if none has been set. This column has the expander arrow drawn next to it.
getFixedHeightMode bool getFixedHeightMode(): Returns whether fixed height mode is turned on for @tree_view.
getGridLines GtkTreeViewGridLines getGridLines(): Returns which grid lines are enabled in @tree_view.
getHeadersClickable bool getHeadersClickable(): Returns whether all header columns are clickable.
getHeadersVisible bool getHeadersVisible(): Returns %TRUE if the headers on the @tree_view are visible.
getHoverExpand bool getHoverExpand(): Returns whether hover expansion mode is turned on for @tree_view.
getHoverSelection bool getHoverSelection(): Returns whether hover selection mode is turned on for @tree_view.
getLevelIndentation int getLevelIndentation(): Returns the amount, in pixels, of extra indentation for child levels in @tree_view.
getModel TreeModelIF getModel(): Returns the model the #GtkTreeView is based on. Returns %NULL if the model is unset.
getNColumns uint getNColumns(): Queries the number of columns in the given @tree_view.
getPathAtPos bool getPathAtPos(int x, int y, TreePath path, TreeViewColumn column, int cellX, int cellY): 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.
getReorderable bool getReorderable(): Retrieves whether the user can reorder the tree via drag-and-drop. See gtk_tree_view_set_reorderable().
getRowSeparatorFunc GtkTreeViewRowSeparatorFunc getRowSeparatorFunc(): Returns the current row separator function.
getRubberBanding bool getRubberBanding(): 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.
getSearchColumn int getSearchColumn(): Gets the column searched on by the interactive search code.
getSearchEntry EditableIF getSearchEntry(): 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.
getSearchEqualFunc GtkTreeViewSearchEqualFunc getSearchEqualFunc(): Returns the compare function currently in use.
getSelection TreeSelection getSelection(): Gets the #GtkTreeSelection associated with @tree_view.
getShowExpanders bool getShowExpanders(): Returns whether or not expanders are drawn in @tree_view.
getStruct void* getStruct(): the main Gtk struct as a void*
getTooltipColumn int getTooltipColumn(): Returns the column of @tree_view’s model which is being used for displaying tooltips on @tree_view’s rows.
getTooltipContext bool getTooltipContext(int x, int y, bool keyboardTip, TreeModelIF model, TreePath path, TreeIter iter): This function is supposed to be used in a #GtkWidget::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.
getTreeViewStruct GtkTreeView* getTreeViewStruct(bool transferOwnership): Get the main Gtk struct
getVisibleRange bool getVisibleRange(TreePath startPath, TreePath endPath): Sets @start_path and @end_path to be the first and last visible path. Note that there may be invisible paths in between.
getVisibleRect void getVisibleRect(GdkRectangle visibleRect): 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.
insertColumn int insertColumn(TreeViewColumn column, int position): 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.
insertColumnWithDataFunc int insertColumnWithDataFunc(int position, string title, CellRenderer cell, GtkTreeCellDataFunc func, void* data, GDestroyNotify dnotify): 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.
isBlankAtPos bool isBlankAtPos(int x, int y, TreePath path, TreeViewColumn column, int cellX, int cellY): 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.
isRubberBandingActive bool isRubberBandingActive(): Returns whether a rubber banding operation is currently being done in @tree_view.
mapExpandedRows void mapExpandedRows(GtkTreeViewMappingFunc func, void* data): Calls @func on all expanded rows.
moveColumnAfter void moveColumnAfter(TreeViewColumn column, TreeViewColumn baseColumn): Moves @column to be after to @base_column. If @base_column is %NULL, then @column is placed in the first position.
removeColumn int removeColumn(TreeViewColumn column): Removes @column from @tree_view.
rowActivated void rowActivated(TreePath path, TreeViewColumn column): Activates the cell determined by @path and @column.
rowExpanded bool rowExpanded(TreePath path): Returns %TRUE if the node pointed to by @path is expanded in @tree_view.
scrollToCell void scrollToCell(TreePath path, TreeViewColumn column, bool useAlign, float rowAlign, float colAlign): 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.
scrollToPoint void scrollToPoint(int treeX, int treeY): 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().
setActivateOnSingleClick void setActivateOnSingleClick(bool single): Cause the #GtkTreeView::row-activated signal to be emitted on a single click instead of a double click.
setColumnDragFunction void setColumnDragFunction(GtkTreeViewColumnDropFunc func, void* userData, GDestroyNotify destroy): 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.
setCursor void setCursor(TreePath path, TreeViewColumn focusColumn, bool startEditing): 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.
setCursorOnCell void setCursorOnCell(TreePath path, TreeViewColumn focusColumn, CellRenderer focusCell, bool startEditing): 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.
setDragDestRow void setDragDestRow(TreePath path, GtkTreeViewDropPosition pos): Sets the row that is highlighted for feedback. If @path is %NULL, an existing highlight is removed.
setEnableSearch void setEnableSearch(bool enableSearch): If @enable_search is set, then the user can type in text to search through the tree interactively (this is sometimes called "typeahead find").
setEnableTreeLines void setEnableTreeLines(bool enabled): Sets whether to draw lines interconnecting the expanders in @tree_view. This does not have any visible effects for lists.
setExpanderColumn void setExpanderColumn(TreeViewColumn 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.
setFixedHeightMode void setFixedHeightMode(bool enable): 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.
setGridLines void setGridLines(GtkTreeViewGridLines gridLines): Sets which grid lines to draw in @tree_view.
setHeadersClickable void setHeadersClickable(bool setting): Allow the column title buttons to be clicked.
setHeadersVisible void setHeadersVisible(bool headersVisible): Sets the visibility state of the headers.
setHoverExpand void setHoverExpand(bool expand): Enables or disables the hover expansion mode of @tree_view. Hover expansion makes rows expand or collapse if the pointer moves over them.
setHoverSelection void setHoverSelection(bool hover): 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.
setLevelIndentation void setLevelIndentation(int 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.
setModel void setModel(TreeModelIF 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.
setReorderable void setReorderable(bool 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.
setRowSeparatorFunc void setRowSeparatorFunc(GtkTreeViewRowSeparatorFunc func, void* data, GDestroyNotify destroy): 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.
setRubberBanding void setRubberBanding(bool enable): 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.
setSearchColumn void setSearchColumn(int column): Sets @column as the column where the interactive search code should search in for the current model.
setSearchEntry void setSearchEntry(EditableIF 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.
setSearchEqualFunc void setSearchEqualFunc(GtkTreeViewSearchEqualFunc searchEqualFunc, void* searchUserData, GDestroyNotify searchDestroy): Sets the compare function for the interactive search capabilities; note that somewhat like strcmp() returning 0 for equality #GtkTreeViewSearchEqualFunc returns %FALSE on matches.
setShowExpanders void setShowExpanders(bool enabled): 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.

setTooltipCell void setTooltipCell(Tooltip tooltip, TreePath path, TreeViewColumn column, CellRenderer 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().
setTooltipColumn void setTooltipColumn(int 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.
setTooltipRow void setTooltipRow(Tooltip tooltip, TreePath path): 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().
