class: TreeView

[54:7] extends: object

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: 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.

  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.

• get_selection ()

  Gets the GtkTreeSelection associated with @tree_view.

• get_show_expanders ()

  Returns whether or not expanders are drawn in @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.

• insert_column (object 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.

  • @p column is The GtkTreeViewColumn to be inserted..
  • @p position is The position to insert @column in..

• is_rubber_banding_active ()

  Returns whether a rubber banding operation is currently being done in

  • @tree_view. ``

• move_column_after (object column, object base_column)

  Moves @column to be after to @base_column. If @base_column is %NULL, then

  • @column is placed in the first position.
  • @p column is The GtkTreeViewColumn to be moved..
  • @p base_column is The GtkTreeViewColumn to be moved relative to.
  • @r None.

• remove_column (object column)

  Removes @column from @tree_view.

  • @p column is The GtkTreeViewColumn to remove..

• row_activated (object path, object column)

  Activates the cell determined by @path and @column.

  • @p path is The GtkTreePath to be activated..
  • @p column is The GtkTreeViewColumn to be activated..
  • @r None.

• row_expanded (object path)

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

  • @p path is A GtkTreePath to test expansion state..

• scroll_to_cell (object path, object column, bool use_align, double row_align, double col_align)

  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.
  • @p path is The path of the row to move to.
  • @p column is The GtkTreeViewColumn to move horizontally to.
  • @p use_align is whether to use alignment arguments, or %FALSE..
  • @p row_align is The vertical alignment of the row specified by @path..
  • @p col_align is The horizontal alignment of the column specified by
  • @column.. ``
  • @r None.

• scroll_to_point (int tree_x, int tree_y)

  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.

  • @p tree_x is X coordinate of new top-left pixel of visible area, or -1.
  • @p tree_y is Y coordinate of new top-left pixel of visible area, or -1.
  • @r None.

• set_activate_on_single_click (bool single)

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

  • @p single is %TRUE to emit row-activated on a single click.
  • @r None.

• set_cursor (object path, object focus_column, bool start_editing)

  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.
  • @p path is A GtkTreePath.
  • @p focus_column is A GtkTreeViewColumn.
  • @p start_editing is %TRUE if the specified cell should start being edited..
  • @r None.

• set_cursor_on_cell (object path, object focus_column, object focus_cell, bool start_editing)

  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.
  • @p path is A GtkTreePath.
  • @p focus_column is A GtkTreeViewColumn.
  • @p focus_cell is A GtkCellRenderer.
  • @p start_editing is %TRUE if the specified cell should start being edited..
  • @r None.

• set_drag_dest_row (object path, string pos)

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

  • @p path is The path of the row to highlight.
  • @p pos is Specifies whether to drop before, after or into the row.
  • @r None.

• set_enable_search (bool 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"). Note that even if this is %FALSE, the user can still initiate a search using the “start-interactive-search” key binding.

  • @p enable_search is %TRUE, if the user can search interactively.
  • @r None.

• set_enable_tree_lines (bool enabled)

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

  • @p enabled is %TRUE to enable tree line drawing, %FALSE otherwise..
  • @r None.

• set_expander_column (object 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. If you do not want expander arrow to appear in your tree, set the expander column to a hidden column.

  • @p column is %NULL, or the column to draw the expander arrow at..
  • @r None.

• set_fixed_height_mode (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.

  • @p enable is %TRUE to enable fixed height mode.
  • @r None.

• set_grid_lines (string grid_lines)

  Sets which grid lines to draw in @tree_view.

  • @p grid_lines is a GtkTreeViewGridLines value indicating which grid lines to enable..

  Sets the visibility state of the headers.

  • @p headers_visible is %TRUE if the headers are visible.
  • @r None.

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

  • @p expand is %TRUE to enable hover selection mode.
  • @r None.

• set_hover_selection (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.

  • @p hover is %TRUE to enable hover selection mode.
  • @r None.

• set_level_indentation (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.
  • @p indentation is the amount, in pixels, of extra indentation in
  • @tree_view.. ``
  • @r None.

• set_model (object 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.

  • @p model is The model..
  • @r None.

• set_reorderable (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. 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.

  • @p reorderable is %TRUE, if the tree can be reordered..
  • @r None.

• set_rubber_banding (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.

  • @p enable is %TRUE to enable rubber banding.
  • @r None.

• set_search_column (int column)

  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.

  • @p column is the column of the model to search in, or -1 to disable searching.
  • @r None.

• set_search_entry (object 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.
  • @p entry is the entry the interactive search code of @tree_view should use.
  • @r None.

• set_show_expanders (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. 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.
  • @p enabled is %TRUE to enable expander drawing, %FALSE otherwise..
  • @r None.

• set_tooltip_cell (object tooltip, object path, object column, object 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(). 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.

  • @p tooltip is a GtkTooltip.
  • @p path is a GtkTreePath.
  • @p column is a GtkTreeViewColumn.
  • @p cell is a GtkCellRenderer.
  • @r None.

• set_tooltip_column (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. 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.

  • @p column is an integer, which is a valid column number for @tree_view’s model.
  • @r None.

• set_tooltip_row (object tooltip, object 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().

  • @p tooltip is a GtkTooltip.
  • @p path is a GtkTreePath.
  • @r None.

• unset_rows_drag_dest ()

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

  • @r None.

• unset_rows_drag_source ()

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

  • @r None.

• columns ()

  Returns get_columns as an Aussom list of wrapper objects. This companion method materializes the full collection up front; use get_columns() when lazy or change-notify access is required.

  • @r An Aussom list of elements.
