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§

impl TreeStore

source

pub fn append(&self, parent: Option<&TreeIter>) -> TreeIter

👎Deprecated: Since 4.10

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

source

pub fn clear(&self)

👎Deprecated: Since 4.10

Removes all rows from @self

Deprecated since 4.10

Use TreeListModel instead

source

pub fn insert(&self, parent: Option<&TreeIter>, position: i32) -> TreeIter

👎Deprecated: Since 4.10

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

Use TreeListModel instead

parent

A valid TreeIter

position

position to insert the new row, or -1 for last

Returns
iter

An unset TreeIter to set to the new row

source

pub fn insert_after( &self, parent: Option<&TreeIter>, sibling: Option<&TreeIter> ) -> TreeIter

👎Deprecated: Since 4.10

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().

Deprecated since 4.10

Use TreeListModel instead

parent

A valid TreeIter

sibling

A valid TreeIter

Returns
iter

An unset TreeIter to set to the new row

source

pub fn insert_before( &self, parent: Option<&TreeIter>, sibling: Option<&TreeIter> ) -> TreeIter

👎Deprecated: Since 4.10

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.

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().

source

pub fn move_after(&self, iter: &TreeIter, position: Option<&TreeIter>)

👎Deprecated: Since 4.10

Use TreeListModel instead

iter

A TreeIter.

position

pub fn prepend(&self, parent: Option<&TreeIter>) -> TreeIter

👎Deprecated: Since 4.10

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

Returns
iter

An unset TreeIter to set to the prepended row

source

pub fn remove(&self, iter: &TreeIter) -> bool

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 instead

Returns

a new TreeStore

source

pub fn insert_with_values( &self, parent: Option<&TreeIter>, position: Option<u32>, columns_and_values: &[(u32, &dyn ToValue)] ) -> TreeIter

👎Deprecated: Since 4.10

position

position to insert the new row, or -1 for last

columns

an array of column numbers

values

source

pub fn set(&self, iter: &TreeIter, columns_and_values: &[(u32, &dyn ToValue)])

👎Deprecated: Since 4.10

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

A valid TreeIter for the row being modified

source

pub fn set_column_types(&self, types: &[Type])

👎Deprecated: Since 4.10

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

source

pub fn set_value(&self, iter: &TreeIter, column: u32, value: &Value)

source§

fn drag_data_received(&self, dest: &TreePath, value: &Value) -> bool

👎Deprecated: Since 4.10
Asks the TreeDragDest to insert a row before the path @dest, deriving the contents of the row from @value. If @dest is outside the tree so that inserting before it is impossible, false will be returned. Also, false may be returned if the new row is not created for some model-specific reason. Should robustly handle a @dest no longer found in the model! Read more

fn row_drop_possible(&self, dest_path: &TreePath, value: &Value) -> bool

👎Deprecated: Since 4.10
Determines whether a drop is possible before the given @dest_path, at the same depth as @dest_path. i.e., can we drop the data in @value at that location. @dest_path does not have to exist; the return value will almost certainly be false if the parent of @dest_path doesn’t exist, though. Read more
