◆ drop_down_menu() [1/2]

gui2::dialogs::drop_down_menu::drop_down_menu	(	styled_widget *	parent,
		const std::vector< config > &	items,
		int	selected_item,
		bool	keep_open
	)

Menu was invoked from a widget (currently a [multi]menu_button).

Its position and markup settings will be derived from there.

		const std::vector< config > &	items,
		int	selected_item,
		bool	use_markup,
		bool	keep_open
	)

Menu was invoked manually.

Position and markup settings must be provided here.

Member Data Documentation

◆ button_pos_

SDL_Rect gui2::dialogs::drop_down_menu::button_pos_

private

The screen location of the menu_button button that triggered this droplist.

Note: we don't adjust the location of this dialog to when resizing the window. Instead this dialog automatically closes itself on resizing.

◆ keep_open_

bool gui2::dialogs::drop_down_menu::keep_open_

private

Whether to keep this dialog open after a click occurs not handled by special exceptions such as scrollbars and toggle buttons.

◆ mouse_down_happened_

bool gui2::dialogs::drop_down_menu::mouse_down_happened_
