## Description

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.

## Details

### GtkTreeView

    typedef struct _GtkTreeView GtkTreeView;

### enum GtkTreeViewDropPosition

    typedef enum
    {
      /* drop before/after this row */
      GTK_TREE_VIEW_DROP_BEFORE,
      GTK_TREE_VIEW_DROP_AFTER,
      /* drop as a child of this row (with fallback to before or after
       * if into is not possible)
       */
      GTK_TREE_VIEW_DROP_INTO_OR_BEFORE,
      GTK_TREE_VIEW_DROP_INTO_OR_AFTER
    } GtkTreeViewDropPosition;

An enum for determining where a dropped row goes.

### GtkTreeViewPrivate

    typedef struct _GtkTreeViewPrivate GtkTreeViewPrivate;

A private struct for internal use only. The definition of this structure is not publically available.

### GtkTreeViewColumnDropFunc ()

    gboolean    (*GtkTreeViewColumnDropFunc)    (GtkTreeView *tree_view,
                                                 GtkTreeViewColumn *column,
                                                 GtkTreeViewColumn *prev_column,
                                                 GtkTreeViewColumn *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.

`tree_view` : | A GtkTreeView
`column` : | The GtkTreeViewColumn being dragged
`prev_column` : | A GtkTreeViewColumn on one side of `column`
`next_column` : | A GtkTreeViewColumn on the other side of `column`
`data` : | user data
Returns : | `TRUE`, if column can be dropped in this spot

### GtkTreeViewMappingFunc ()

    void        (*GtkTreeViewMappingFunc)       (GtkTreeView *tree_view,
                                                 GtkTreePath *path,
                                                 gpointer user_data);

Function used for gtk_tree_view_map_expanded_rows.

`tree_view` : | A GtkTreeView
`path` : | The path that's expanded
`user_data` : | user data

### GtkTreeViewSearchEqualFunc ()

    gboolean    (*GtkTreeViewSearchEqualFunc)   (GtkTreeModel *model,
                                                 gint column,
                                                 const gchar *key,
                                                 GtkTreeIter *iter,
                                                 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.

`model` : | the GtkTreeModel being searched
`column` : | the search column set by `gtk_tree_view_set_search_column()`
`key` : | the key string to compare with
`iter` : | a GtkTreeIter pointing the row of `model` that should be compared with `key`.
`search_data` : | user data from `gtk_tree_view_set_search_equal_func()`
Returns : | `FALSE` if the row matches, `TRUE` otherwise.

### gtk_tree_view_new ()

    GtkWidget*  gtk_tree_view_new               (void);

Creates a new GtkTreeView widget.

Returns : | A newly created GtkTreeView widget.

### gtk_tree_view_new_with_model ()

    GtkWidget*  gtk_tree_view_new_with_model    (GtkTreeModel *model);

Creates a new GtkTreeView widget with the model initialized to `model`.

`model` : | the model.
Returns : | A newly created GtkTreeView widget.

### gtk_tree_view_get_model ()

    GtkTreeModel* gtk_tree_view_get_model       (GtkTreeView *tree_view);

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

`tree_view` : | a GtkTreeView
Returns : | A GtkTreeModel, or `NULL` if none is currently being used.

### gtk_tree_view_set_model ()

    void        gtk_tree_view_set_model         (GtkTreeView *tree_view,
                                                 GtkTreeModel *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.

`tree_view` : | A GtkTreeNode.
`model` : | The model.

### gtk_tree_view_get_selection ()

    GtkTreeSelection* gtk_tree_view_get_selection
                                                (GtkTreeView *tree_view);

Gets the GtkTreeSelection associated with `tree_view`.

`tree_view` : | A GtkTreeView.
Returns : | A GtkTreeSelection object.

                                                 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).

`tree_view` : | a GtkTreeView
`setting` : | `TRUE` if the tree requires reading across rows

                                                 GtkDestroyNotify 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.

`tree_view` : | A GtkTreeView.
`func` : | A function to determine which columns are reorderable, or `NULL`.
`user_data` : | User data to be passed to `func`, or `NULL`
`destroy` : | Destroy notifier for `user_data`, or `NULL`

### gtk_tree_view_scroll_to_point ()

    void        gtk_tree_view_scroll_to_point   (GtkTreeView *tree_view,

                                                 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 window 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.

`tree_view` : | a GtkTreeView
`tree_x` : | X coordinate of new top-left pixel of visible area, or -1
`tree_y` : | Y coordinate of new top-left pixel of visible area, or -1

### gtk_tree_view_scroll_to_cell ()

    void        gtk_tree_view_scroll_to_cell    (GtkTreeView *tree_view,
                                                 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.

`tree_view` : | A GtkTreeView.
`path` : | The path of the row to move to, or `NULL`.
`column` : | The GtkTreeViewColumn to move horizontally to, or `NULL`.
`use_align` : | whether to use alignment arguments, or `FALSE`.
`row_align` : | The vertical alignment of the row specified by `path`.
`col_align` : | The horizontal alignment of the column specified by `column`.

                                                 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.

`tree_view` : | A GtkTreeView
`path` : | A GtkTreePath

                                                 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 `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.

`tree_view` : | A GtkTreeView
`path` : | A GtkTreePath

                                                 GtkTreeViewColumn **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 GtkTreePath must be freed with `gtk_tree_path_free()` when you are done with it.

`tree_view` : | A GtkTreeView
`func` : | A function to be called
`data` : | User data to be passed to the function.

### gtk_tree_view_row_expanded ()

    gboolean    gtk_tree_view_row_expanded      (GtkTreeView *tree_view,
                                                 GtkTreePath *path);

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

`tree_view` : | A GtkTreeView.
`path` : | A GtkTreePath to test expansion state.
Returns : | `TRUE` if path is expanded.

### 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.

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.

`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()`.

`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 widget coordinates. 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 ()`. 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.

`tree_view` : | A GtkTreeView.
`x` : | The x position to be identified.
`y` : | The y position to be identified.
`path` : | A pointer to a GtkTreePath pointer to be filled in, or `NULL`
`column` : | A pointer to a GtkTreeViewColumn pointer to be filled in, or `NULL`
`cell_x` : | A pointer where the X coordinate relative to the cell can be placed, or `NULL`
`cell_y` : | A pointer where the Y coordinate relative to the cell can be placed, or `NULL`
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 tree 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.

`tree_view` : | a GtkTreeView
`path` : | a GtkTreePath for the row, or `NULL` to get only horizontal coordinates
`column` : | a GtkTreeViewColumn for the column, or `NULL` to get only vertical coordinates
`rect` : | rectangle to fill with cell rect

### gtk_tree_view_get_background_area ()

    void        gtk_tree_view_get_background_area
                                                (GtkTreeView *tree_view,

                                                 GtkTreeViewColumn *column,
                                                 GdkRectangle *rect);

Fills the bounding rectangle in tree 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 tree window (except for the area used for header buttons). 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.

`tree_view` : | a GtkTreeView
`path` : | a GtkTreePath for the row, or `NULL` to get only horizontal coordinates
`column` : | a GtkTreeViewColumn for the column, or `NULL` to get only vertical coordiantes

### gtk_tree_view_get_bin_window ()

    GdkWindow*  gtk_tree_view_get_bin_window    (GtkTreeView *tree_view);

                                                 GtkDestroyNotify destroy);

This function should almost never be used. It is meant for private use by ATK for determining the number of visible children that are removed when the user collapses a row, or a row is deleted.

`tree_view` : | A GtkTreeView
`func` : | Function to be called when a view row is destroyed, or `NULL`
`data` : | User data to be passed to `func`, or `NULL`
`destroy` : | Destroy notifier for `data`, or `NULL`

### GtkTreeViewRowSeparatorFunc ()

    gboolean    (*GtkTreeViewRowSeparatorFunc)  (GtkTreeModel *model,
                                                 GtkTreeIter *iter,
                                                 gpointer data);

Function type for determining whether the row pointed to by `iter` should be rendered as a separator. A common way to implement this is to have a boolean column in the model, whose values the GtkTreeViewRowSeparatorFunc returns.

`model` : | the GtkTreeModel
`iter` : | a GtkTreeIter pointing at a row in `model`
`data` : | user data
Returns : | `TRUE` if the row is a separator

### gtk_tree_view_get_row_separator_func ()

    GtkTreeViewRowSeparatorFunc gtk_tree_view_get_row_separator_func
                                                (GtkTreeView *tree_view);

Returns the current row separator function.

`tree_view` : | a GtkTreeView
Returns : | the current row separator function.

Since 2.6

### gtk_tree_view_set_row_separator_func ()

    void        gtk_tree_view_set_row_separator_func
                                                (GtkTreeView *tree_view,
                                                 GtkTreeViewRowSeparatorFunc func,
                                                 gpointer data,
                                                 GtkDestroyNotify 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.

`tree_view` : | a GtkTreeView
`func` : | a GtkTreeViewRowSeparatorFunc
`data` : | user data to pass to `func`, or `NULL`
`destroy` : | destroy notifier for `data`, or `NULL`

Since 2.6
