Detailed Description

Model Of:

The semantics of a checkbox are that of a flag. One would use a checkbox when you want to have a selectable option turned on or off. There is a third state the checkbox can be in, the undetermined state, which is neither true or false. This is often represented with a dash or a filled checkbox.

Constructor & Destructor Documentation

checkbox_t	(	const std::string &	name,
		const any_regular_t &	true_value,
		const any_regular_t &	false_value,
		theme_t	theme,
		const std::string &	alt_text
	)

Parameters:

name	is the name of the widget

Member Function Documentation

void display ( const any_regular_t & value )

Note:: When the new value is set for the checkbox_t it will be compared to the true- and false-values specified when the widget was created. If the new value matches the true-value, the checkbox will be checked. If the new value matches the false-value, the checkbox will not be checked. Otherwise, the checkbox will be set to an undetermined state.
