Detailed Description

This widget is based off the Fl_Tabs widget, but instead of displaying tabs it only changes "tabs" under program control.

Its primary purpose is to support "wizards" that step a user through configuration or troubleshooting tasks.

As with Fl_Tabs, wizard panes are composed of child (usually Fl_Group) widgets. Navigation buttons must be added separately.

Constructor & Destructor Documentation

Fl_Wizard()

Fl_Wizard::Fl_Wizard	(	int	xx,
		int	yy,
		int	ww,
		int	hh,
		const char *	l = 0
	)

The constructor creates the Fl_Wizard widget at the specified position and size.

The inherited destructor destroys the widget and its children.

Member Function Documentation
