Implementations

impl DropDownBuilder

pub fn new() -> Self

Create a new DropDownBuilder.

pub fn build(self) -> DropDown

Build the DropDown.

pub fn enable_search(self, enable_search: bool) -> Self

Whether to show a search entry in the popup.

Note that search requires property::DropDown::expression to be set.

pub fn expression(self, expression: &Expression) -> Self

An expression to evaluate to obtain strings to match against the search term.

See property::DropDown::enable-search for how to enable search. If property::DropDown::factory is not set, the expression is also used to bind strings to labels produced by a default factory.

pub fn factory<P: IsA<ListItemFactory>>(self, factory: &P) -> Self

Factory for populating list items.

pub fn list_factory<P: IsA<ListItemFactory>>(self, list_factory: &P) -> Self

The factory for populating list items in the popup.

If this is not set, property::DropDown::factory is used.

pub fn model<P: IsA<ListModel>>(self, model: &P) -> Self

Model for the displayed items.

pub fn selected(self, selected: u32) -> Self

The position of the selected item.

If no item is selected, the property has the value GTK_INVALID_LIST_POSITION.

pub fn can_focus(self, can_focus: bool) -> Self

Whether the widget or any of its descendents can accept the input focus.

pub fn can_target(self, can_target: bool) -> Self

Whether the widget can receive pointer events.

pub fn css_classes(self, css_classes: Vec<String>) -> Self

A list of css classes applied to this widget.

pub fn opacity(self, opacity: f64) -> Self

The requested opacity of the widget.

pub fn overflow(self, overflow: Overflow) -> Self
