CtkTreeViewColumnDropFunc ()

gboolean
(*CtkTreeViewColumnDropFunc) (CtkTreeView *tree_view,
                              CtkTreeViewColumn *column,
                              CtkTreeViewColumn *prev_column,
                              CtkTreeViewColumn *next_column,
                              gpointer data);

Function type for determining whether column can be dropped in a particular spot (as determined by prev_column and next_column ). In left to right locales, prev_column is on the left of the potential drop spot, and next_column is on the right. In right to left mode, this is reversed. This function should return TRUE if the spot is a valid drop spot. Please note that returning TRUE does not actually indicate that the column drop was made, but is meant only to indicate a possible drop spot to the user.

CtkTreeViewMappingFunc ()

void
(*CtkTreeViewMappingFunc) (CtkTreeView *tree_view,
                           CtkTreePath *path,
                           gpointer user_data);

Function used for ctk_tree_view_map_expanded_rows().

                               gpointer search_data);

A function used for checking whether a row in model matches a search key string entered by the user. Note the return value is reversed from what you would normally expect, though it has some similarity to strcmp() returning 0 for equal strings.

ctk_tree_view_new ()

CtkWidget *
ctk_tree_view_new (void);

Creates a new CtkTreeView widget.

ctk_tree_view_get_level_indentation ()

                                  gboolean 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 ctk_tree_view_set_level_indentation(). This does not have any visible effects for lists.

Since: 2.12

void
ctk_tree_view_set_rules_hint (CtkTreeView *tree_view,
                              gboolean setting);

Sets a hint for the theme to draw even/odd rows in the tree_view with different colors, also known as "zebra striping".

This function tells the CTK+ theme that the user interface for your application requires users to read across tree rows and associate cells with one another.

Do not use it just because you prefer the appearance of the ruled tree; that’s a question for the theme. Some themes will draw tree rows in alternating colors even when rules are turned off, and users who prefer that appearance all the time can choose those themes. You should call this function only as a semantic hint to the theme engine that your tree makes alternating colors useful from a functional standpoint (since it has lots of columns, generally).

ctk_tree_view_get_rules_hint ()

gboolean
ctk_tree_view_get_rules_hint (CtkTreeView *tree_view);

Gets the setting set by ctk_tree_view_set_rules_hint().

                                GDestroyNotify dnotify);

Convenience function that inserts a new column into the CtkTreeView with the given cell renderer and a CtkTreeCellDataFunc to set cell renderer attributes (normally using data from the model). See also ctk_tree_view_column_set_cell_data_func(), ctk_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 CTK_TREE_VIEW_COLUMN_FIXED.

                                 CtkTreeViewColumn *column,
                                 CtkTreeViewColumn *base_column);

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

ctk_tree_view_set_expander_column ()

void
ctk_tree_view_set_expander_column (CtkTreeView *tree_view,
                                   CtkTreeViewColumn *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.

ctk_tree_view_get_expander_column ()

CtkTreeViewColumn *
ctk_tree_view_get_expander_column (CtkTreeView *tree_view);

void
ctk_tree_view_set_column_drag_function
                               (CtkTreeView *tree_view,
                                CtkTreeViewColumnDropFunc func,
                                gpointer user_data,
                                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 CtkTreeViewColumn being dragged, the two CtkTreeViewColumn s determining the drop spot, and user_data . If either of the CtkTreeViewColumn 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.

ctk_tree_view_scroll_to_point ()

void
ctk_tree_view_scroll_to_point (CtkTreeView *tree_view,
                               gint tree_x,
                               gint 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 ctk_tree_view_scroll_to_cell().

If either tree_x or tree_y are -1, then that direction isn’t scrolled.

ctk_tree_view_scroll_to_cell ()

void
ctk_tree_view_scroll_to_cell (CtkTreeView *tree_view,
                              CtkTreePath *path,
                              CtkTreeViewColumn *column,
                              gboolean use_align,
                              gfloat row_align,
                              gfloat 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.

ctk_tree_view_set_cursor ()

void
ctk_tree_view_set_cursor (CtkTreeView *tree_view,
                          CtkTreePath *path,

                          gboolean 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 ctk_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.

ctk_tree_view_set_cursor_on_cell ()

void
ctk_tree_view_set_cursor_on_cell (CtkTreeView *tree_view,
                                  CtkTreePath *path,
                                  CtkTreeViewColumn *focus_column,
                                  CtkCellRenderer *focus_cell,
                                  gboolean 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 ctk_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.

Since: 2.2

ctk_tree_view_get_cursor ()

ctk_tree_view_get_cursor (CtkTreeView *tree_view,
                          CtkTreePath **path,
                          CtkTreeViewColumn **focus_column);

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.

The returned CtkTreePath must be freed with ctk_tree_path_free() when you are done with it.

ctk_tree_view_row_activated ()

void
ctk_tree_view_row_activated (CtkTreeView *tree_view,
                             CtkTreePath *path,

Since: 2.2

ctk_tree_view_expand_row ()

gboolean
ctk_tree_view_expand_row (CtkTreeView *tree_view,
                          CtkTreePath *path,
                          gboolean open_all);

Opens the row so its children are visible.

ctk_tree_view_collapse_row ()

gboolean
ctk_tree_view_collapse_row (CtkTreeView *tree_view,
                            CtkTreePath *path);

Collapses a row (hides its child rows, if they exist).

ctk_tree_view_map_expanded_rows ()

void
ctk_tree_view_map_expanded_rows (CtkTreeView *tree_view,
                                 CtkTreeViewMappingFunc func,
                                 gpointer data);

ctk_tree_view_set_reorderable ()

void
ctk_tree_view_set_reorderable (CtkTreeView *tree_view,
                               gboolean reorderable);

This function is a convenience function to allow you to reorder models that support the CtkTreeDragSourceIface and the CtkTreeDragDestIface. Both CtkTreeStore and CtkListStore 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 “row-inserted” and “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.

ctk_tree_view_get_reorderable ()

gboolean
ctk_tree_view_get_reorderable (CtkTreeView *tree_view);

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

                               gint *cell_y);

Finds the path at the point (x , y ), relative to bin_window coordinates (please see ctk_tree_view_get_bin_window()). That is, x and y are relative to an events coordinates. x and y must come from an event on the tree_view only where event->window == ctk_tree_view_get_bin_window(). It is primarily for things like popup menus. If path is non-NULL, then it will be filled with the CtkTreePath at that point. This path should be freed with ctk_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 ctk_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.

For converting widget coordinates (eg. the ones you get from CtkWidget::query-tooltip), please see ctk_tree_view_convert_widget_to_bin_window_coords().

                               gint *cell_y);

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.

The x and y coordinate that are provided must be relative to bin_window coordinates. That is, x and y must come from an event on tree_view where event->window == ctk_tree_view_get_bin_window().

For converting widget coordinates (eg. the ones you get from CtkWidget::query-tooltip), please see ctk_tree_view_convert_widget_to_bin_window_coords().

The path , column , cell_x and cell_y arguments will be filled in likewise as for ctk_tree_view_get_path_at_pos(). Please see ctk_tree_view_get_path_at_pos() for more information.

                             CdkRectangle *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 ctk_cell_renderer_render(). This function is only valid if tree_view is realized.

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 ctk_cell_renderer_render(). These background areas tile to cover the entire bin window. Contrast with the cell_area , returned by ctk_tree_view_get_cell_area(), which returns only the cell itself, excluding surrounding borders and the tree expander area.

ctk_tree_view_set_tooltip_row ()

void
ctk_tree_view_set_tooltip_row (CtkTreeView *tree_view,
                               CtkTooltip *tooltip,
                               CtkTreePath *path);

Sets the tip area of tooltip to be the area covered by the row at path . See also ctk_tree_view_set_tooltip_column() for a simpler alternative. See also ctk_tooltip_set_tip_area().

Since: 2.12

ctk_tree_view_set_tooltip_cell ()

void
ctk_tree_view_set_tooltip_cell (CtkTreeView *tree_view,
                                CtkTooltip *tooltip,
                                CtkTreePath *path,
                                CtkTreeViewColumn *column,
                                CtkCellRenderer *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 ctk_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 ctk_tree_view_set_tooltip_column() for a simpler alternative.

ctk_tree_view_get_tooltip_context ()

gboolean
ctk_tree_view_get_tooltip_context (CtkTreeView *tree_view,
                                   gint *x,
                                   gint *y,
                                   gboolean keyboard_tip,
                                   CtkTreeModel **model,
                                   CtkTreePath **path,
                                   CtkTreeIter *iter);

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

The return value indicates whether there is a tree view row at the given coordinates (TRUE) or not (FALSE) for mouse tooltips. For keyboard tooltips the row returned will be the cursor row. When TRUE, then any of model , path and iter which have been provided will be set to point to that row and the corresponding model. x and y will always be converted to be relative to tree_view ’s bin_window if keyboard_tooltip is FALSE.

Since: 2.12

ctk_tree_view_get_tooltip_column ()

gint
ctk_tree_view_get_tooltip_column (CtkTreeView *tree_view);

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

Since: 2.12

ctk_tree_view_set_tooltip_column ()

void
ctk_tree_view_set_tooltip_column (CtkTreeView *tree_view,
                                  gint column);

If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have CtkTreeView 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, “has-tooltip” will be set to TRUE and tree_view will connect a “query-tooltip” signal handler.

Note that the signal handler sets the text with ctk_tooltip_set_markup(), so &, <, etc have to be escaped in the text.

               gpointer        user_data)

The “move-cursor” signal is a keybinding signal 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 ctk_tree_view_set_cursor() and ctk_tree_view_set_cursor_on_cell() when moving horizontally “move-cursor” does not reset the current selection.

Flags: Action

The “row-activated” signal

void
user_function (CtkTreeView       *tree_view,
               CtkTreePath       *path,
               CtkTreeViewColumn *column,
               gpointer           user_data)

The "row-activated" signal is emitted when the method ctk_tree_view_row_activated() is called, 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 the "activate-on-single-click" property set to TRUE. It 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 CtkTreeSelection.

Flags: Action

The “row-collapsed” signal
