pub struct ColumnViewColumn { /* private fields */ }
Expand description

ColumnViewColumn represents the columns being added to ColumnView.

The main ingredient for a ColumnViewColumn is the ListItemFactory that tells the columnview how to create cells for this column from items in the model.

Columns have a title, and can optionally have a header menu set with set_header_menu().

A sorter can be associated with a column using set_sorter(), to let users influence sorting by clicking on the column header.

Implements

glib::ObjectExt

Implementations

Creates a new ColumnViewColumn that uses the given @factory for mapping items to widgets.

You most likely want to call ColumnView::append_column() next.

The function takes ownership of the argument, so you can write code like:

⚠️ The following code is in c ⚠️

column = gtk_column_view_column_new (_("Name"),
  gtk_builder_list_item_factory_new_from_resource ("/name.ui"));
title

Title to use for this column

factory

The factory to populate items with

Returns

a new ColumnViewColumn using the given @factory

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

This method returns an instance of ColumnViewColumnBuilder which can be used to create ColumnViewColumn objects.

Gets the column view that’s currently displaying this column.

If @self has not been added to a column view yet, None is returned.

Returns

The column view displaying @self.

Returns whether this column should expand.

Returns

true if this column expands

Gets the factory that’s currently used to populate list items for this column.

Returns

The factory in use

Gets the fixed width of the column.

Returns

the fixed with of the column

Gets the menu model that is used to create the context menu for the column header.

Returns

the GMenuModel

Returns whether this column is resizable.

Returns

true if this column is resizable

Returns the sorter that is associated with the column.

Returns

the Sorter of @self

Returns the title set with gtk_column_view_column_set_title().

Returns

The column’s title

Returns whether this column is visible.

Returns

true if this column is visible

Sets the column to take available extra space.

The extra space is shared equally amongst all columns that have the expand set to true.

expand

true if this column should expand to fill available sace

Sets the ListItemFactory to use for populating list items for this column.

factory

the factory to use

If @fixed_width is not -1, sets the fixed width of @column; otherwise unsets it.

Setting a fixed width overrides the automatically calculated width. Interactive resizing also sets the “fixed-width” property.

fixed_width

the new fixed width, or -1

Sets the menu model that is used to create the context menu for the column header.

a GMenuModel

Sets whether this column should be resizable by dragging.

resizable

whether this column should be resizable

Associates a sorter with the column.

If @sorter is None, the column will not let users change the sorting by clicking on its header.

This sorter can be made active by clicking on the column header, or by calling ColumnView::sort_by_column().

See ColumnView::sorter() for the necessary steps for setting up customizable sorting for ColumnView.

sorter

the Sorter to associate with @column

Sets the title of this column.

The title is displayed in the header of a ColumnView for this column and is therefore user-facing text that should be translated.

title

Title to use for this column

Sets whether this column should be visible in views.

visible

whether this column should be visible
