Detailed Description

Class for a toggle button.

Quite some code looks like toggle_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...

A toggle panel is an item which can hold multiple other items. The difference between a grid and a panel is that it's possible to define how a panel looks. A grid in an invisible container to just hold the items. The toggle panel is a combination of the panel and a toggle button, it allows a toggle button with its own grid.

The resolution for a toggle panel also contains the following keys:

Key	Type	Description
top_border	unsigned	The size which isn't used for the client area.
bottom_border	unsigned	The size which isn't used for the client area.
left_border	unsigned	The size which isn't used for the client area.
right_border	unsigned	The size which isn't used for the client area.

The following states exist:

state_enabled - the button is enabled and not selected.
state_disabled - the button is disabled and not selected.
state_focussed - the mouse is over the button and not selected.
state_enabled_selected - the button is enabled and selected.
state_disabled_selected - the button is disabled and selected.

state_focussed_selected - the mouse is over the button and selected. Variables:

Key	Type	Default	Description
grid	grid	mandatory	Defines the grid with the widgets to place on the panel.
return_value_id	string	""	The return value id.
return_value	int	0	The return value.

Member Enumeration Documentation

◆ state_t

enum gui2::toggle_panel::state_t

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.

◆ find_at() [2/2]

widget * gui2::toggle_panel::find_at	(	const point &	coordinate,
		const bool	must_be_active
	)

overridevirtual

See widget::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.
