## 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.

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 `gtk_tree_view_convert_widget_to_bin_window_coords()` (and vice versa), for the latter `gtk_tree_view_convert_bin_window_to_tree_coords()` (and vice versa).

### GtkTreeView as GtkBuildable

The GtkTreeView implementation of the GtkBuildable interface accepts GtkTreeViewColumn objects as <child> elements in UI definitions.

## 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,
                                                             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,

                                                             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 ()

    gint                gtk_tree_view_get_level_indentation (GtkTreeView *tree_view);

Returns the amount, in pixels, of extra indentation for child levels in `tree_view`.

`tree_view` : | a GtkTreeView.
Returns : | the amount of extra indentation for child levels in `tree_view`. A return value of 0 means that this feature is disabled.

Since 2.12

### gtk_tree_view_get_show_expanders ()

    gboolean            gtk_tree_view_get_show_expanders    (GtkTreeView *tree_view);

Returns whether or not expanders are drawn in `tree_view`.

`tree_view` : | a GtkTreeView.
Returns : | `TRUE` if expanders are drawn in `tree_view`, `FALSE` otherwise.

Since 2.12

### gtk_tree_view_set_level_indentation ()

                                                             gint 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.

`tree_view` : | a GtkTreeView
`indentation` : | the amount, in pixels, of extra indentation in `tree_view`.

Since 2.12

### gtk_tree_view_set_show_expanders ()

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.

`tree_view` : | a GtkTreeView
`enabled` : | `TRUE` to enable expander drawing, `FALSE` otherwise.

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

### gtk_tree_view_get_rules_hint ()

    gboolean            gtk_tree_view_get_rules_hint        (GtkTreeView *tree_view);

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.

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
`position` : | Position to insert, -1 for append
`title` : | column title
`cell` : | cell renderer for column

`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);

Returns the column that is the current expander column. This column has the expander arrow drawn next to it.

### 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_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 `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.

If `path` is invalid for `model`, the current cursor (if any) will be unset and the function will return without failing.

`tree_view` : | A GtkTreeView
`path` : | A GtkTreePath
`focus_column` : | A GtkTreeViewColumn, or `NULL`
`start_editing` : | `TRUE` if the specified cell should start being edited.

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.

`tree_view` : | A GtkTreeView
`path` : | A GtkTreePath
`focus_column` : | A GtkTreeViewColumn, or `NULL`
`focus_cell` : | A GtkCellRenderer, or `NULL`
`start_editing` : | `TRUE` if the specified cell should start being edited.

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.

`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 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()`.

`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`
`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,

                                                             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.

`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 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.

`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

### gtk_tree_view_get_visible_rect ()

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.

`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 **start_path,
                                                             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 ()

Determines the destination row for a given position. `drag_x` and `drag_y` are expected to be in widget coordinates. 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.

`tree_view` : | a GtkTreeView
`drag_x` : | the position to determine the destination row for
`drag_y` : | the position to determine the destination row for
`path` : | Return location for the path of the highlighted row, or `NULL`.

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.

`tree_view` : | A GtkTreeView
`enable_search` : | `TRUE`, if the user can search interactively

### gtk_tree_view_get_enable_search ()

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.

`tree_view` : | A GtkTreeView
`column` : | the column of the model to search in, or -1 to disable searching

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.

### gtk_tree_view_get_tooltip_context ()

    gboolean            gtk_tree_view_get_tooltip_context   (GtkTreeView *tree_view,
                                                             gint *x,
                                                             gint *y,
                                                             gboolean keyboard_tip,
                                                             GtkTreeModel **model,
                                                             GtkTreePath **path,
                                                             GtkTreeIter *iter);

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`.

`tree_view` : | a GtkTreeView
`x` : | the x coordinate (relative to widget coordinates)
`y` : | the y coordinate (relative to widget coordinates)
`keyboard_tip` : | whether this is a keyboard tooltip or not
`model` : | a pointer to receive a GtkTreeModel or `NULL`
`path` : | a pointer to receive a GtkTreePath or `NULL`
`iter` : | a pointer to receive a GtkTreeIter or `NULL`
Returns : | whether or not the given tooltip context points to a row.

### gtk_tree_view_get_tooltip_column ()

    gint                gtk_tree_view_get_tooltip_column    (GtkTreeView *tree_view);

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

`tree_view` : | a GtkTreeView
Returns : | the index of the tooltip column that is currently being used, or -1 if this is disabled.

### 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.

`tree_view` : | a GtkTreeView
`column` : | an integer, which is a valid column number for `tree_view`'s model
