Struct gtk::TreeViewColumn

#[repr(transparent)]
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][TreeWidget] for an overview of all the objects and data types related to the tree widget and how they work together.

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

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

pub fn clear_attributes(&self, cell_renderer: &impl IsA<CellRenderer>)

pub fn pack_end(&self, cell_renderer: &impl IsA<CellRenderer>, expand: bool)

pub fn pack_start(&self, cell_renderer: &impl IsA<CellRenderer>, expand: bool)

pub fn clear(&self)
