pub struct TreeStore { /* private fields */ }
Expand description
Use TreeListModel
instead
A tree-like data structure that can be used with the TreeView
.
The TreeStore
object is a list model for use with a TreeView
widget. It implements the TreeModel
interface, and consequently,
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 dragcrate::TreeDragSource
and dropcrate::TreeDragDest interfaces.
TreeStore
is deprecated since GTK 4.10, and should not be used in newly
written code. You should use TreeListModel
for a tree-like model
object.
§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:
<object class="GtkTreeStore">
<columns>
<column type="gchararray"/>
<column type="gchararray"/>
<column type="gint"/>
</columns>
</object>

Implementations§
Source§impl TreeStore
impl TreeStore
Sourcepub fn append(&self, parent: Option<&TreeIter>) -> TreeIter
👎Deprecated: Since 4.10
pub fn append(&self, parent: Option<&TreeIter>) -> TreeIter
Appends a new row to @self.
If @parent is non-None
, then it will append the new row after the last
child of @parent, otherwise it will append a row to the top level.
The @iter parameter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().
§Deprecated since 4.10
Use TreeListModel
instead
§parent
A valid TreeIter
§Returns
§iter
An unset TreeIter
to set to the appended row
Sourcepub fn insert(&self, parent: Option<&TreeIter>, position: i32) -> TreeIter
👎Deprecated: Since 4.10
pub fn insert(&self, parent: Option<&TreeIter>, position: i32) -> TreeIter
Creates a new row at @position.
If parent is non-None
, then the row will be made a child of @parent.
Otherwise, the row will be created at the toplevel.
If @position is -1
or is larger than the number of rows at that level,
then the new row will be inserted to the end of the list.
The @iter parameter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().
§Deprecated since 4.10

) -> TreeIter
👎Deprecated: Since 4.10
pub fn insert_after( &self, parent: Option<&TreeIter>, sibling: Option<&TreeIter>, ) -> TreeIter
Inserts a new row after @sibling.
If @sibling is None
, then the row will be prepended to @parent’s children.
If @parent and @sibling are None
, then the row will be prepended to the
toplevel.
If both @sibling and @parent are set, then @parent must be the parent of @sibling. When @sibling is set, @parent is optional.
The @iter parameter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().

pub fn insert_before( &self, parent: Option<&TreeIter>, sibling: Option<&TreeIter>, ) -> TreeIter
Inserts a new row before @sibling.
If @sibling is None
, then the row will be appended to @parent’s children.
If @parent and @sibling are None
, then the row will be appended to the
toplevel.
If both @sibling and @parent are set, then @parent must be the parent of @sibling. When @sibling is set, @parent is optional.

Sourcepub fn new(column_types: &[Type]) -> Self
👎Deprecated: Since 4.10
pub fn new(column_types: &[Type]) -> Self
Creates a new tree store.
The tree store will have @n_columns, with each column using the corresponding type passed to this function.
Note that only types derived from standard GObject fundamental types are supported.
As an example:
⚠️ The following code is in c ⚠️
gtk_tree_store_new (3, G_TYPE_INT, G_TYPE_STRING, GDK_TYPE_TEXTURE);
will create a new TreeStore
with three columns of type
int
, gchararray
, and gdk::Texture
respectively.
§Deprecated since 4.10
Use TreeListModel

§Returns
a new TreeStore
Sourcepub fn insert_with_values(
&self,
parent: Option<&TreeIter>,
position: Option<u32>,

👎Deprecated: Since 4.10
pub fn insert_with_values( &self, parent: Option<&TreeIter>, position: Option<u32>, columns_and_values: &[(u32, &dyn ToValue)], ) -> TreeIter
A variant of gtk_tree_store_insert_with_values() which takes the columns and values as two arrays, instead of varargs.
This function is mainly intended for language bindings.
§Deprecated since 4.10
Use TreeListModel
instead
§parent
A valid TreeIter
§position
position to insert the new row, or -1 for last
§columns
an array of column numbers
§values

Sourcepub fn reorder(&self, parent: &TreeIter, new_order: &[u32])
👎Deprecated: Since 4.10
pub fn reorder(&self, parent: &TreeIter, new_order: &[u32])
Reorders the children of @parent in @self to follow the order indicated by @new_order.
Note that this function only works with unsorted stores.
§Deprecated since 4.10
Use TreeListModel
instead
§parent
the parent of the children to re-order
§new_order
an array of integers mapping the new position
of each child to its old position before the re-ordering,
i.e. new_order[newpos] = oldpos
Sourcepub fn set(&self, iter: &TreeIter, columns_and_values: &[(u32, &dyn ToValue)])
👎Deprecated: Since 4.10
pub fn set(&self, iter: &TreeIter, columns_and_values: &[(u32, &dyn ToValue)])
Sets the value of one or more cells in the row referenced by @iter.
The variable argument list should contain integer column numbers, each column number followed by the value to be set.
The list is terminated by a value of -1
.
For example, to set column 0 with type G_TYPE_STRING
to “Foo”, you would
write
⚠️ The following code is in c ⚠️
gtk_tree_store_set (store, iter, 0, "Foo", -1);
The value will be referenced by the store if it is a G_TYPE_OBJECT
, and it
will be copied if it is a G_TYPE_STRING
or G_TYPE_BOXED
.
§Deprecated since 4.10
Use TreeListModel
instead
§iter

for the row being modified
Sourcepub fn set_column_types(&self, types: &[Type])
👎Deprecated: Since 4.10
pub fn set_column_types(&self, types: &[Type])
Sets the type of the columns in a tree store.
This function is meant primarily for types that inherit from
TreeStore
, and should only be used when constructing a new
TreeStore
.
This functions cannot be called after a row has been added,
or a method on the TreeModel
interface is called on the
tree store.
§Deprecated since 4.10
Use TreeListModel
instead
§types
An array of GType
types, one for each column
