Detailed Description

Class for a toggle button.

Quite some code looks like ttoggle_button maybe we should inherit from that but let's test first. the problem is that the toggle_button has an icon we don't want, but maybe look at refactoring later. but maybe we should also ditch the icon, not sure however since it's handy for checkboxes...

Member Enumeration Documentation

enum gui2::ttoggle_panel::tstate

private

Possible states of the widget.

Note the order of the states must be the same as defined in settings.hpp. Also note the internals do assume the order for 'up' and 'down' to be the same and also that 'up' is before 'down'. 'up' has no suffix, 'down' has the SELECTED suffix.

Todo:: only due to the fact our definition is slightly different from tpanel_definition we need to override this function and do about the same, look at a way to 'fix' that.

twidget * gui2::ttoggle_panel::find_at	(	const tpoint &	coordinate,
		const bool	must_be_active
	)

overridevirtual

See twidget::find_at.

Todo:: since there is no mouse event nesting (or event nesting at all) we need to capture all events. This means items on the panel will never receive an event, which gives problems with for example the intended button on the addon panel. So we need to chain mouse events as well and also add a handled flag for them.
