FaSelection

Usage

let selection = fa_selection(&mut builder, "Select choice")
    .choices(["Choice 1", "Choice 2"])
    .build();

Return Entity which must be used inside a containable widget.

Available methods

• id(&str)
• class(&str)
• display(&str)
• choices([&str])
• color(&str): set custom background color.

Example

let plans = fa_selection(&mut builder, "Select plan")
    .choices(["Personal", "Team", "Enterprise"])
    .build();
);

let subscriptions = fa_selection(&mut builder, "Select subscription payment")
    .choices(["Weekly", "Monthly", "Annually"])
    .build();
);

fa_container(&mut builder).children([plans, subscriptions]).build();

Change event

Whenever fa_selection's value changes, it emits an event called FaSelectionChangeEvent that contains updated value.

pub struct FaSelectionChangeEvent {
    pub entity: Entity,
    pub widget_id: Option<String>,
    pub new_value: String
}

Example,

fn my_system(mut events: EventReader<FaSelectionChangeEvent>) {
    for e in events.read() {
        // make sure this works only with selection that have id provided
        if let Some(id) = e.widget_id.as_ref() {
            match id.as_str() {
                "#selection-one" => {
                    println!("{:?}", e.new_value);
                }
                "#selection-two" => {
                    // do something with #selection-two new value
                }
            }
        }
    }
}
