#[repr(transparent)]pub struct TreeStore { /* private fields */ }
Expand description
The TreeStore
object is a list model for use with a TreeView
widget. It implements the TreeModel
interface, and consequentially,
can use all of the methods available there. It also implements the
TreeSortable
interface so it can be sorted by the view. Finally,
it also implements the tree
[drag and drop][gtk3-GtkTreeView-drag-and-drop]
interfaces.
GtkTreeStore as GtkBuildable
The GtkTreeStore implementation of the Buildable
interface allows
to specify the model columns with a <columns>
element that may contain
multiple <column>
elements, each specifying one model column. The “type”
attribute specifies the data type for the column.
An example of a UI Definition fragment for a tree store:
⚠️ The following code is in xml ⚠️
<object class="GtkTreeStore">
<columns>
<column type="gchararray"/>
<column type="gchararray"/>
<column type="gint"/>
</columns>
</object>

Implementations
sourceimpl TreeStore
impl TreeStore
sourcepub fn new(column_types: &[Type]) -> TreeStore
pub fn new(column_types: &[Type]) -> TreeStore
Creates a new tree store as with n_columns
columns each of the types passed
in. Note that only types derived from standard GObject fundamental types
are supported.
As an example, gtk_tree_store_new (3, G_TYPE_INT, G_TYPE_STRING, GDK_TYPE_PIXBUF);
will create a new TreeStore
with three columns, of type
gint
, gchararray
, and gdk_pixbuf::Pixbuf
respectively.
n_columns
number of columns in the tree store
Returns
a new TreeStore
