### Class

# Gtk TreeViewColumn

deprecated: 4.10 since: 4.0

#### Description [src]

    final class Gtk.TreeViewColumn : GObject.InitiallyUnowned
      implements Gtk.Buildable, Gtk.CellLayout {
      /* No available fields */
    }

A visible column in a `GtkTreeView` widget

The `GtkTreeViewColumn` object represents a visible column in a `GtkTreeView` widget. It allows to set properties of the column header, and functions as a holding pen for the cell renderers which determine how the data in the column is displayed.

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, and to the `GtkTreeView` documentation for specifics about the CSS node structure for treeviews and their headers.

Available since: 4.0

Deprecated since: 4.10

Use `GtkColumnView` and `GtkColumnViewColumn` instead of `GtkTreeView` to show a tabular list.

#### Ancestors

#### Constructors

###### gtk_tree_view_column_new

Creates a new `GtkTreeViewColumn`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_new_with_area

Creates a new `GtkTreeViewColumn` using `area` to render its cells.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_new_with_attributes

Creates a new `GtkTreeViewColumn` with a number of default values. This is equivalent to calling gtk_tree_view_column_set_title(), gtk_tree_view_column_pack_start(), and `gtk_tree_view_column_set_attributes()` on the newly created `GtkTreeViewColumn`.

deprecated: 4.10 since: 4.0

#### Instance methods

###### gtk_tree_view_column_add_attribute

Adds an attribute mapping to the list in `tree_column`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_cell_get_position

Obtains the horizontal position and size of a cell in a column.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_cell_get_size

Obtains the width and height needed to render the column. This is used primarily by the `GtkTreeView`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_cell_is_visible

Returns `TRUE` if any of the cells packed into the `tree_column` are visible. For this to be meaningful, you must first initialize the cells with `gtk_tree_view_column_cell_set_cell_data()`

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_cell_set_cell_data

Sets the cell renderer based on the `tree_model` and `iter`. That is, for every attribute mapping in `tree_column`, it will get a value from the set column on the `iter`, and use that value to set the attribute on the cell renderer. This is used primarily by the `GtkTreeView`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_clear

Unsets all the mappings on all renderers on the `tree_column`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_clear_attributes

Clears all existing attributes previously set with gtk_tree_view_column_set_attributes().

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_clicked

Emits the “clicked” signal on the column. This function will only work if `tree_column` is clickable.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_focus_cell

Sets the current keyboard focus to be at `cell`, if the column contains 2 or more editable and activatable cells.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_get_alignment

Returns the current x alignment of `tree_column`. This value can range between 0.0 and 1.0.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_get_max_width

Returns the maximum width in pixels of the `tree_column`, or -1 if no maximum width is set.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_get_spacing

Returns the spacing of `tree_column`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_get_title

Returns the title of the widget.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_get_tree_view

Returns the `GtkTreeView` wherein `tree_column` has been inserted. If `column` is currently not inserted in any tree view, `NULL` is returned.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_get_visible

Returns `TRUE` if `tree_column` is visible.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_get_widget

Returns the `GtkWidget` in the button on the column header.

deprecated: 4.10 since: 4.0

Returns the current X offset of `tree_column` in pixels.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_pack_end

Adds the `cell` to end of the column. If `expand` is `FALSE`, then the `cell` is allocated no more space than it needs. Any unused space is divided evenly between cells for which `expand` is `TRUE`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_pack_start

Packs the `cell` into the beginning of the column. If `expand` is `FALSE`, then the `cell` is allocated no more space than it needs. Any unused space is divided evenly between cells for which `expand` is `TRUE`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_queue_resize

Flags the column, and the cell renderers added to this column, to have their sizes renegotiated.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_alignment

Sets the alignment of the title or custom widget inside the column header. The alignment determines its location inside the button — 0.0 for left, 0.5 for center, 1.0 for right.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_attributes

Sets the attributes in the list as the attributes of `tree_column`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_cell_data_func

Sets the `GtkTreeCellDataFunc` to use for the column.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_clickable

Sets the header to be active if `clickable` is `TRUE`. When the header is active, then it can take keyboard focus, and can be clicked.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_expand

Sets the column to take available extra space. This space is shared equally amongst all columns that have the expand set to `TRUE`. If no column has this option set, then the last column gets all extra space. By default, every column is created with this `FALSE`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_fixed_width

If `fixed_width` is not -1, sets the fixed width of `tree_column`; otherwise unsets it. The effective value of `fixed_width` is clamped between the minimum and maximum width of the column; however, the value stored in the “fixed-width” property is not clamped. If the column sizing is `GTK_TREE_VIEW_COLUMN_GROW_ONLY` or `GTK_TREE_VIEW_COLUMN_AUTOSIZE`, setting a fixed width overrides the automatically calculated width. Note that `fixed_width` is only a hint to GTK; the width actually allocated to the column may be greater or less than requested.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_max_width

Sets the maximum width of the `tree_column`. If `max_width` is -1, then the maximum width is unset. Note, the column can actually be wider than max width if it’s the last column in a view. In this case, the column expands to fill any extra space.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_min_width

Sets the minimum width of the `tree_column`. If `min_width` is -1, then the minimum width is unset.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_reorderable

If `reorderable` is `TRUE`, then the column can be reordered by the end user dragging the header.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_resizable

If `resizable` is `TRUE`, then the user can explicitly resize the column by grabbing the outer edge of the column button.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_sizing

Sets the growth behavior of `tree_column` to `type`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_sort_column_id

Sets the logical `sort_column_id` that this column sorts on when this column is selected for sorting. Doing so makes the column header clickable.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_sort_indicator

Call this function with a `setting` of `TRUE` to display an arrow in the header button indicating the column is sorted. Call `gtk_tree_view_column_set_sort_order()` to change the direction of the arrow.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_sort_order

Changes the appearance of the sort indicator.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_spacing

Sets the spacing field of `tree_column`, which is the number of pixels to place between cell renderers packed into it.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_title

Sets the title of the `tree_column`. If a custom widget has been set, then this value is ignored.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_visible

Sets the visibility of `tree_column`.

deprecated: 4.10 since: 4.0

###### gtk_tree_view_column_set_widget

Sets the widget in the header to be `widget`. If widget is `NULL`, then the header button is set with a `GtkLabel` set to the title of `tree_column`.

deprecated: 4.10 since: 4.0
