Struct TreeViewColumn 

pub struct TreeViewColumn { /* private fields */ }

The GtkTreeViewColumn 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.

Properties

cell-area

The CellArea used to layout cell renderers for this column.

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

Implementations

impl TreeViewColumn

pub const NONE: Option<&'static TreeViewColumn> = None

pub fn new() -> TreeViewColumn

Creates a new TreeViewColumn.

Returns

A newly created TreeViewColumn.

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

Creates a new TreeViewColumn using area to render its cells.

area

the CellArea that the newly created column should use to layout cells.

Returns

A newly created TreeViewColumn.

pub fn builder() -> TreeViewColumnBuilder

Creates a new builder-pattern struct instance to construct TreeViewColumn objects.

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

impl TreeViewColumn

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

Creates a new TreeViewColumn with a number of default values. This is equivalent to calling TreeViewColumnExt::set_title(), TreeViewColumnExt::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",
                                                      renderer,
                                                      "text", TEXT_COLUMN,
                                                      "foreground", COLOR_COLUMN,
                                                      NULL);
 }

title

The title to set the header to

cell

The CellRenderer

Returns

A newly created TreeViewColumn.

pub fn set_attributes( &self, cell_renderer: &impl IsA<CellRenderer>, attributes: &[(&str, i32)], )
