Struct SelectElement

pub struct SelectElement {
    pub(crate) options: Vec<SelectElementOptionOrOptgroup>,
    pub(crate) selected_option: Option<usize>,
    pub(crate) position: DeviceIntRect,
    pub(crate) responder: IpcResponder<Option<usize>>,
}

Represents a dialog triggered by clicking a <select> element.

Fields

options: Vec<SelectElementOptionOrOptgroup>

selected_option: Option<usize>

position: DeviceIntRect

responder: IpcResponder<Option<usize>>

Implementations

impl SelectElement

pub(crate) fn new( options: Vec<SelectElementOptionOrOptgroup>, selected_option: Option<usize>, position: DeviceIntRect, ipc_sender: IpcSender<Option<usize>>, ) -> Self

pub fn position(&self) -> DeviceIntRect

Return the area occupied by the <select> element that triggered the prompt.

The embedder should use this value to position the prompt that is shown to the user.

pub fn options(&self) -> &[SelectElementOptionOrOptgroup]

Consecutive <option> elements outside of an <optgroup> will be combined into a single anonymous group, whose label is None.

pub fn select(&mut self, id: Option<usize>)

Mark a single option as selected.

If there is already a selected option and the <select> element does not support selecting multiple options, then the previous option will be unselected.

pub fn selected_option(&self) -> Option<usize>

pub fn submit(self)

Resolve the prompt with the options that have been selected by calling [select] previously.
