Struct gtk4::ColumnViewColumn [−][src]
pub struct ColumnViewColumn(_);
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.

pub fn new<P: IsA<ListItemFactory>>(
title: Option<&str>,
factory: Option<&P>
) -> ColumnViewColumn
pub fn new<P: IsA<ListItemFactory>>(
title: Option<&str>,
factory: Option<&P>
) -> ColumnViewColumn
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"));

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 factory that’s currently used to populate list items for this column.
Returns
The factory in use
Gets the menu model that is used to create the context menu for the column header.
Returns
the GMenuModel
Sets the ListItemFactory
to use for populating list items for this
column.

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.
menu
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.
