Detailed Description

An icon pair (identical to WIconPair)

This widget manages two images, only one of which is shown at a single time.

The widget may also react to click events, by changing state.

This widget is part of the Wt treelist example, where it is used to represent the expand/collapse icons, and the corresponding map open/close icon.

See also: TreeNode

Definition at line 34 of file IconPair.h.

Constructor & Destructor Documentation

IconPair::IconPair	(	const std::string	icon1URI,
		const std::string	icon2URI,
		bool	clickIsSwitch = `true`,
		Wt::WContainerWidget *	parent = `0`
	)

Construct a two-state icon widget.

The constructor takes the URI of the two icons. When clickIsSwitch is set true, clicking on the icon will switch state.
