void
gtk_tree_view_set_rules_hint (GtkTreeView *tree_view,
                              gboolean setting);

This function tells GTK+ that the user interface for your application requires users to read across tree rows and associate cells with one another. By default, GTK+ will then render the tree with alternating row colors. 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).

Parameters

tree_view

a GtkTreeView

 

setting

TRUE if the tree requires reading across rows

 

gtk_tree_view_get_rules_hint ()

gboolean
gtk_tree_view_get_rules_hint (GtkTreeView *tree_view);

Gets the setting set by gtk_tree_view_set_rules_hint().

Parameters

tree_view

a GtkTreeView

 

Returns

TRUE if rules are useful for the user of this tree

                                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.

Parameters

tree_view

A GtkTreeView.

 

func

A function to determine which columns are reorderable, or NULL.

[allow-none]

user_data

User data to be passed to func , or NULL.

                              GtkTreePath *path,
                              GtkTreeViewColumn *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.

Parameters

tree_view

A GtkTreeView.

 

path

The path of the row to move to, or NULL.

[allow-none]

column

The GtkTreeViewColumn to move horizontally to, or NULL.

[allow-none]

use_align

                          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 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.

Parameters

A GtkTreeView

 

path

A GtkTreePath

 

focus_column

A GtkTreeViewColumn, or NULL.

[allow-none]

gtk_tree_view_set_reorderable ()

void
gtk_tree_view_set_reorderable (GtkTreeView *tree_view,
                               gboolean reorderable);

This function is a convenience function to allow you to reorder models that support the GtkDragSourceIface and the GtkDragDestIface. 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 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.

Parameters

tree_view

A GtkTreeView.

 

reorderable

TRUE, if the tree can be reordered.

 

gtk_tree_view_get_reorderable ()

gboolean
gtk_tree_view_get_reorderable (GtkTreeView *tree_view);

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

Parameters

tree_view

a GtkTreeView

 

Returns

TRUE if the tree can be reordered.


gtk_tree_view_get_path_at_pos ()

gboolean
gtk_tree_view_get_path_at_pos (GtkTreeView *tree_view,
                               gint x,
                               gint y,
                               GtkTreePath **path,
                               GtkTreeViewColumn **column,
                               gint *cell_x,
                               gint *cell_y);

Finds the path at the point (x , y ), relative to bin_window coordinates (please see gtk_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 == gtk_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 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.

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

Parameters

tree_view

A GtkTreeView.

 

x

The x position to be identified (relative to bin_window).

 

y

The y position to be identified (relative to bin_window).

 

path

A pointer to a GtkTreePath pointer to be filled in, or NULL.

[out][allow-none]

column

A pointer to a GtkTreeViewColumn pointer to be filled in, or NULL.

[out][transfer none][allow-none]

cell_x

A pointer where the X coordinate relative to the cell can be placed, or NULL.

[out][allow-none]

cell_y

A pointer where the Y coordinate relative to the cell can be placed, or NULL.

[out][allow-none]

Returns

TRUE if a row exists at that coordinate.


gtk_tree_view_get_cell_area ()

void
gtk_tree_view_get_cell_area (GtkTreeView *tree_view,
                             GtkTreePath *path,
                             GtkTreeViewColumn *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.

Parameters

tree_view

a GtkTreeView

 

path

a GtkTreePath for the row, or NULL to get only horizontal coordinates.

[allow-none]

column

a GtkTreeViewColumn for the column, or NULL to get only vertical coordinates.

[allow-none]

rect

rectangle to fill with cell rect.

gtk_tree_view_get_background_area ()

void
gtk_tree_view_get_background_area (GtkTreeView *tree_view,
                                   GtkTreePath *path,
                                   GtkTreeViewColumn *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.

Parameters

tree_view

a GtkTreeView

 

path

a GtkTreePath for the row, or NULL to get only horizontal coordinates.

[allow-none]

column

a GtkTreeViewColumn for the column, or NULL to get only vertical coordiantes.

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.

Parameters

tree_view

a GtkTreeView

 

visible_rect

rectangle to fill.

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.

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.

Parameters

tree_view

a GtkTreeView

 

x

the x coordinate (relative to widget coordinates).

[inout]

y

the y coordinate (relative to widget coordinates).

[inout]

keyboard_tip

whether this is a keyboard tooltip or not

 

model

a pointer to receive a GtkTreeModel or NULL.

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

Parameters

tree_view

a GtkTreeView

 

Returns

the index of the tooltip column that is currently being used, or -1 if this is disabled.

Since: 2.12


gtk_tree_view_set_tooltip_column ()

void
gtk_tree_view_set_tooltip_column (GtkTreeView *tree_view,
                                  gint 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, “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 gtk_tooltip_set_markup(), so &, <, etc have to be escaped in the text.

Parameters

tree_view

a GtkTreeView

 

column

an integer, which is a valid column number for tree_view 's model
