Module tip 

Tooltip properties and widget.

The tooltip and tooltip_fn properties can be set on any widget to git it a tooltip. The tooltip itself can also be any widget, but the Tip! widget is recommended. You can also set a tooltip that only appears when the widget is disabled using disabled_tooltip.

The example below declares a button that toggles enabled showing different tooltips depending on the state.

use zng::prelude::*;

let enabled = var(true);
Button! {
    tip::tooltip = Tip!(Text!("enabled tooltip"));
    tip::disabled_tooltip = Tip!(Text!("disabled tooltip"));

    on_click = hn!(enabled, |_| enabled.set(false));
    gesture::on_disabled_click = hn!(enabled, |_| enabled.set(true));
    child = Text!(enabled.map(|&e| formatx!("enabled = {e}")));
    widget::enabled;
}
