§Implementors

Provided Methods§

Source

fn active_id(&self) -> Option<GString>

👎Deprecated:

Since 4.10

Returns the ID of the active row of @self.

This value is taken from the active row and the column specified by the id-column property of @self (see set_id_column()).

The returned value is an interned string which means that you can compare the pointer by value to other interned strings and that you must not free it.

If the id-column property of @self is not set, or if no row is active, or if the active row has a None ID value, then None is returned.

§Deprecated since 4.10

Use DropDown

§Returns

the ID of the active row

Source

fn active_iter(&self) -> Option<TreeIter>

👎Deprecated:

Since 4.10

Sets @iter to point to the currently active item.

If no item is active, @iter is left unchanged.

§Deprecated since 4.10

Use DropDown

§Returns

true if @iter was set, false otherwise

§`iter`

A TreeIter

Source

fn button_sensitivity(&self) -> SensitivityType

👎Deprecated:

Since 4.10

Returns whether the combo box sets the dropdown button sensitive or not when there are no items in the model.

§Deprecated since 4.10

Use DropDown

§Returns

SensitivityType::On if the dropdown button is sensitive when the model is empty, SensitivityType::Off if the button is always insensitive or SensitivityType::Auto if it is only sensitive as long as the model has one item to be selected.

Source

fn child(&self) -> Option<Widget>

👎Deprecated:

Since 4.10

Gets the child widget of @self.

§Deprecated since 4.10

Use DropDown

§Returns

the child widget of @self

Source

fn entry_text_column(&self) -> i32

👎Deprecated:

Since 4.10

Returns the column which @self is using to get the strings from to display in the internal entry.

§Deprecated since 4.10

Use DropDown

§Returns

A column in the data source model of @self.

Source

fn has_entry(&self) -> bool

👎Deprecated:

Since 4.10

Returns whether the combo box has an entry.

§Deprecated since 4.10

Use DropDown

§Returns

whether there is an entry in @self.

Source

fn id_column(&self) -> i32

👎Deprecated:

Since 4.10

Returns the column which @self is using to get string IDs for values from.

§Deprecated since 4.10

Use DropDown

§Returns

A column in the data source model of @self.

Source

fn model(&self) -> Option<TreeModel>

👎Deprecated:

Since 4.10

Returns the TreeModel of @self.

§Deprecated since 4.10

Use DropDown

§Returns

A TreeModel which was passed during construction.

Source

fn is_popup_fixed_width(&self) -> bool

👎Deprecated:

Since 4.10

Gets whether the popup uses a fixed width.

§Deprecated since 4.10

Use DropDown

§Returns

true if the popup uses a fixed width

Source

fn popdown(&self)

👎Deprecated:

Since 4.10

Hides the menu or dropdown list of @self.

This function is mostly intended for use by accessibility technologies; applications should have little use for it.

§Deprecated since 4.10

Use DropDown

👎Deprecated:

Since 4.10

Pops up the menu or dropdown list of @self.

This function is mostly intended for use by accessibility technologies; applications should have little use for it.

Before calling this, @self must be mapped, or nothing will happen.

§Deprecated since 4.10

Use DropDown

Source

fn popup_for_device(&self, device: &Device)

👎Deprecated:

Since 4.10

Pops up the menu of @self.

Note that currently this does not do anything with the device, as it was previously only used for list-mode combo boxes, and those were removed in GTK 4. However, it is retained in case similar functionality is added back later.

§Deprecated since 4.10

Use DropDown

§`device`

a gdk::Device

Source

fn set_active_id(&self, active_id: Option<&str>) -> bool

👎Deprecated:

Since 4.10

Changes the active row of @self to the one that has an ID equal to @active_id.

If @active_id is None, the active row is unset. Rows having a None ID string cannot be made active by this function.

If the id-column property of @self is unset or if no row has the given ID then the function does nothing and returns false.

§Deprecated since 4.10

Use DropDown

§`active_id`

the ID of the row to select

§Returns

true if a row with a matching ID was found. If a None @active_id was given to unset the active row, the function always returns true.

Source

fn set_active_iter(&self, iter: Option<&TreeIter>)

👎Deprecated:

Since 4.10

Sets the current active item to be the one referenced by @iter.

If @iter is None, the active item is unset.

§Deprecated since 4.10

Use DropDown

§`iter`

The TreeIter

Source

fn set_button_sensitivity(&self, sensitivity: SensitivityType)

👎Deprecated:

Since 4.10

Sets whether the dropdown button of the combo box should update its sensitivity depending on the model contents.

§Deprecated since 4.10

Use DropDown

§`sensitivity`

specify the sensitivity of the dropdown button

Source

fn set_child(&self, child: Option<&impl IsA<Widget>>)

👎Deprecated:

Since 4.10

Sets the child widget of @self.

§Deprecated since 4.10

Use DropDown

§`child`

the child widget

Source

fn set_entry_text_column(&self, text_column: i32)

👎Deprecated:

Since 4.10

Sets the model column which @self should use to get strings from to be @text_column.

For this column no separate CellRenderer is needed.

The column @text_column in the model of @self must be of type G_TYPE_STRING.

This is only relevant if @self has been created with has-entry as true.

§Deprecated since 4.10

Use DropDown

§`text_column`

A column in @model to get the strings from for the internal entry

Source

fn set_id_column(&self, id_column: i32)

👎Deprecated:

Since 4.10

Sets the model column which @self should use to get string IDs for values from.

The column @id_column in the model of @self must be of type G_TYPE_STRING.

§Deprecated since 4.10

Use DropDown

§`id_column`

A column in @model to get string IDs for values from

Source

fn set_model(&self, model: Option<&impl IsA<TreeModel>>)

👎Deprecated:

Since 4.10

Sets the model used by @self to be @model.

Will unset a previously set model (if applicable). If model is None, then it will unset the model.

Note that this function does not clear the cell renderers, you have to call CellLayoutExt::clear() yourself if you need to set up different cell renderers for the new model.

§Deprecated since 4.10

Use DropDown

§`model`

A TreeModel

Source

fn set_popup_fixed_width(&self, fixed: bool)

👎Deprecated:

Since 4.10

s width should be a fixed width.

If @fixed is true, the popup’s width is set to match the allocated width of the combo box.

§Deprecated since 4.10

Use DropDown

§`fixed`

whether to use a fixed popup width

Source

fn set_row_separator_func<P: Fn(&TreeModel, &TreeIter) -> bool + 'static>( &self, func: P, )

👎Deprecated:

Since 4.10

Sets the row separator function, which is used to determine whether a row should be drawn as a separator.

If the row separator function is None, no separators are drawn. This is the default value.

§Deprecated since 4.10

Use DropDown

§`func`

a GtkTreeViewRowSeparatorFunc

Source

fn has_frame(&self) -> bool

👎Deprecated:

Since 4.10

The has-frame property controls whether a frame is drawn around the entry.

Source

fn set_has_frame(&self, has_frame: bool)

👎Deprecated:

Since 4.10

The has-frame property controls whether a frame is drawn around the entry.

Source

fn is_popup_shown(&self) -> bool

👎Deprecated:

Since 4.10

Whether the combo boxes dropdown is popped up.

Note that this property is mainly useful, because it allows you to connect to notify::popup-shown.

Source

fn connect_activate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

👎Deprecated:

Since 4.10

Available on crate feature v4_6 only.

Emitted to when the combo box is activated.

The ::activate signal on ComboBox is an action signal and emitting it causes the combo box to pop up its dropdown.

Source

fn emit_activate(&self)

👎Deprecated:

Since 4.10

Available on crate feature v4_6 only.

Source

fn connect_changed<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

👎Deprecated:

Since 4.10

Emitted when the active item is changed.

The can be due to the user selecting a different item from the list, or due to a call to set_active_iter(). It will also be emitted while typing into the entry of a combo box with an entry.

Source

fn connect_format_entry_text<F: Fn(&Self, &str) -> String + 'static>( &self, f: F, ) -> SignalHandlerId

👎Deprecated:

Since 4.10
