Expand description

Use ColumnView and ColumnViewColumn instead of TreeView to show a tabular list A visible column in a TreeView widget

The TreeViewColumn object represents a visible column in a TreeView 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 TreeView documentation for specifics about the CSS node structure for treeviews and their headers.

§cell-area

The CellArea used to layout cell renderers for this column.

If no area is specified when creating the tree view column with gtk_tree_view_column_new_with_area() a horizontally oriented CellAreaBox will be used.

pub fn new() -> TreeViewColumn

👎Deprecated:

Since 4.10

Creates a new TreeViewColumn.

§Deprecated since 4.10

Use GtkColumnView instead

§Returns

A newly created TreeViewColumn.

Source

pub fn with_area(area: &impl IsA<CellArea>) -> TreeViewColumn

👎Deprecated:

Since 4.10

Creates a new TreeViewColumn using @area to render its cells.

§Deprecated since 4.10

Use GtkColumnView instead

pub fn builder() -> TreeViewColumnBuilder

👎Deprecated:

This method returns an instance of TreeViewColumnBuilder which can be used to create TreeViewColumn objects.

Source

pub fn add_attribute( &self, cell_renderer: &impl IsA<CellRenderer>, attribute: &str, column: i32, )

👎Deprecated:

Adds an attribute mapping to the list in @self.

The @column is the column of the model to get a value from, and the @attribute is the parameter on @cell_renderer to be set from the value. So for example if column 2 of the model contains strings, you could have the “text” attribute of a CellRendererText get its values from column 2.

§attribute

An attribute on the renderer

pub fn set_cell_data_func<P: Fn(&TreeViewColumn, &CellRenderer, &TreeModel, &TreeIter) + 'static>( &self, cell_renderer: &impl IsA<CellRenderer>, func: P, )

👎Deprecated:

Since 4.10

Sets the GtkTreeCellDataFunc to use for the column.

This function is used instead of the standard attributes mapping for setting the column value, and should set the value of @self’s cell renderer as appropriate. @func may be None to remove an older one.

§Deprecated since 4.10

Use GtkColumnView instead

§cell_renderer

A CellRenderer

§func

The GtkTreeCellDataFunc to use.

§func_data

The user data for @func.

pub fn set_clickable(&self, clickable: bool)

👎Deprecated:

Since 4.10

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 since 4.10

Use GtkColumnView instead

§clickable

true if the header is active.

Source

pub fn set_expand(&self, expand: bool)

👎Deprecated:

Since 4.10

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.

Along with “fixed-width”, the “expand” property changes when the column is resized by the user.

§Deprecated since 4.10

Use GtkColumnView instead

§expand

true if the column should expand to fill available space.

Source

pub fn set_fixed_width(&self, fixed_width: i32)

👎Deprecated:

Since 4.10

If @fixed_width is not -1, sets the fixed width of @self; 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 TreeViewColumnSizing::GrowOnly or TreeViewColumnSizing::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.

Along with “expand”, the “fixed-width” property changes when the column is resized by the user.

§Deprecated since 4.10

Use GtkColumnView instead

§fixed_width

The new fixed width, in pixels, or -1.

Source

pub fn set_max_width(&self, max_width: i32)

👎Deprecated:

Since 4.10

Sets the maximum width of the @self. 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 since 4.10

Use GtkColumnView instead

§max_width

The maximum width of the column in pixels, or -1.

Source

pub fn set_min_width(&self, min_width: i32)

👎Deprecated:

Since 4.10

Sets the minimum width of the @self. If @min_width is -1, then the minimum width is unset.

§Deprecated since 4.10

Use GtkColumnView instead

§min_width

The minimum width of the column in pixels, or -1.

Source

pub fn set_reorderable(&self, reorderable: bool)

👎Deprecated:

Since 4.10

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

§Deprecated since 4.10

Use GtkColumnView instead

§reorderable

true, if the column can be reordered.

Source

pub fn set_resizable(&self, resizable: bool)

👎Deprecated:

Since 4.10

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

If resizable is true and sizing mode of the column is TreeViewColumnSizing::Autosize, then the sizing mode is changed to TreeViewColumnSizing::GrowOnly.

§Deprecated since 4.10

Use GtkColumnView instead

§resizable

true, if the column can be resized

Source

pub fn set_sizing(&self, type_: TreeViewColumnSizing)

👎Deprecated:

Source

pub fn set_sort_column_id(&self, sort_column_id: i32)

👎Deprecated:

Since 4.10

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 since 4.10

Use GtkColumnView instead

§sort_column_id

The @sort_column_id of the model to sort on.

Source

pub fn set_sort_indicator(&self, setting: bool)

👎Deprecated:

Since 4.10

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 since 4.10

Use GtkColumnView instead

§setting

true to display an indicator that the column is sorted

Source

pub fn set_sort_order(&self, order: SortType)

👎Deprecated:

Since 4.10

Changes the appearance of the sort indicator.

This does not actually sort the model. Use gtk_tree_view_column_set_sort_column_id() if you want automatic sorting support. This function is primarily for custom sorting behavior, and should be used in conjunction with gtk_tree_sortable_set_sort_column_id() to do that. For custom models, the mechanism will vary.

The sort indicator changes direction to indicate normal sort or reverse sort. Note that you must have the sort indicator enabled to see anything when calling this function; see gtk_tree_view_column_set_sort_indicator().

§Deprecated since 4.10

Use GtkColumnView instead

§order

sort order that the sort indicator should indicate

impl TreeViewColumn

Source

pub fn with_attributes( title: &str, cell_renderer: &impl IsA<CellRenderer>, attributes: &[(&str, i32)], ) -> Self

👎Deprecated:

Since 4.10

Creates a new TreeViewColumn 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 TreeViewColumn.

Here’s a simple example:

⚠️ The following code is in c ⚠️

 enum { TEXT_COLUMN, COLOR_COLUMN, N_COLUMNS };
 // ...
 {
   GtkTreeViewColumn *column;
   GtkCellRenderer   *renderer = gtk_cell_renderer_text_new ();

   column = gtk_tree_view_column_new_with_attributes ("Title",
