Detailed Description

Basic button class providing a selectable rectangular area.

This class is derived from coAction for input device events, and it is derived from coUIElement to inherit the basic UI element functionality. Additionally it offers the chance to rotate the content.

Parameters

xs,ys,zs size = scaling factor for respective dimension (1 is default)

Reimplemented from vrui::coUIElement.

◆ setState()

void vrui::coRotButton::setState	(	bool	state,
		bool	generateEvent = `false`

Set button press state.

Parameters

state	button press state
generateEvent	if true, onPress and onRelease events are generated

◆ updateSwitch()

void vrui::coRotButton::updateSwitch ( )

Update the geometry switch.

The switch state depends on both the button's selection state and press state. Thus, four switch states need to be considered.
