Expand description

A trigger widget usable with PopoverWidget. Implemented for Button and IconButton. Captures the few points where the two triggers differ; everything else is handled by the generic wrapper.

Required Methods§

Source

fn default_has_popup() -> HasPopup

The has_popup kind announced by AT when the caller doesn’t override it. Button → [HasPopup::Dialog]; IconButton → [HasPopup::Menu].

Source

fn default_show_caret() -> bool

Whether the disclosure caret is painted by default. Button → false (text buttons advertise via an inline trailing chevron); IconButton → true (icon-only triggers have no label slot).

Source

fn caret_role(&self, interaction: &Signal<InteractionState>) -> Signal<TextRole>

The TextRole the disclosure caret tints with, derived from the shared interaction signal so the caret and trigger tint together across hover / press / focus / disabled. Only called when a caret is shown.
