## 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.

`GTK_TREE_VIEW_DROP_BEFORE` | dropped row is inserted before
`GTK_TREE_VIEW_DROP_AFTER` | dropped row is inserted after
`GTK_TREE_VIEW_DROP_INTO_OR_BEFORE` | dropped row becomes a child or is inserted before
`GTK_TREE_VIEW_DROP_INTO_OR_AFTER` | dropped row becomes a child or is inserted after

### 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,

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

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

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.

`tree_view` : | A GtkTreeView.
`column` : | The GtkTreeViewColumn to be inserted.
`position` : | The position to insert `column` in.
Returns : | The number of columns in `tree_view` after insertion.

Creates a new GtkTreeViewColumn and inserts it into the `tree_view` at `position`. If `position` is -1, then the newly created column is inserted at the end. The column is initialized with the attributes given. 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.

`tree_view` : | A GtkTreeView
`position` : | The position to insert the new column in.
`title` : | The title to set the header to.
`cell` : | The GtkCellRenderer.

Convenience function that inserts a new column into the GtkTreeView with the given cell renderer and a GtkCellDataFunc 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.

`tree_view` : | a GtkTreeView

`tree_view` : | A GtkTreeView
Returns : | A list of GtkTreeViewColumn s

### gtk_tree_view_move_column_after ()

    void                gtk_tree_view_move_column_after     (GtkTreeView *tree_view,
                                                             GtkTreeViewColumn *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.

`tree_view` : | A GtkTreeView
`column` : | `NULL`, or the column to draw the expander arrow at.

### gtk_tree_view_get_expander_column ()

    GtkTreeViewColumn*  gtk_tree_view_get_expander_column   (GtkTreeView *tree_view);

### gtk_tree_view_set_column_drag_function ()

    void                gtk_tree_view_set_column_drag_function
                                                            (GtkTreeView *tree_view,

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`.

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.

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.

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

`tree_view` : | a GtkTreeView
`path` : | path to a row in the `tree_view`
Returns : | `TRUE` if the row was collapsed.

### gtk_tree_view_map_expanded_rows ()

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,

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 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,

                                                             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,

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
`rect` : | rectangle to fill with cell background rect

Fills `visible_rect` with the currently-visible region of the buffer, in tree coordinates. Convert to widget coordinates with `gtk_tree_view_tree_to_widget_coords()`. Tree coordinates start at 0,0 for row 0 of the tree, and cover the entire scrollable area of the tree.

`tree_view` : | a GtkTreeView
`visible_rect` : | rectangle to fill

### gtk_tree_view_get_visible_range ()

    gboolean            gtk_tree_view_get_visible_range     (GtkTreeView *tree_view,

                                                             GtkTreePath **end_path);

Sets `start_path` and `end_path` to be the first and last visible path. Note that there may be invisible paths in between.

The paths should be freed with `gtk_tree_path_free()` after use.

`tree_view` : | A GtkTreeView
`start_path` : | Return location for start of region, or `NULL`.
`end_path` : | Return location for end of region, or `NULL`.
Returns : | `TRUE`, if valid paths were placed in `start_path` and `end_path`.

### gtk_tree_view_get_bin_window ()

    GdkWindow*          gtk_tree_view_get_bin_window        (GtkTreeView *tree_view);

Returns the window that `tree_view` renders to. This is used primarily to compare to `event->window` to confirm that the event on `tree_view` is on the right window.

`tree_view` : | A GtkTreeView
Returns : | A GdkWindow, or `NULL` when `tree_view` hasn't been realized yet

### gtk_tree_view_widget_to_tree_coords ()
