Detailed Description

The PickCallback class is group node with callbacks when some child is picked.

It provides an easy way of adding interactivity to your scene graph, since you can insert this group node in your inventor file, and just search for all PickCallback nodes when your program starts to add callbacks. You can also connect to the trigger field if you want some other node to trigger when something is picked.

Member Function Documentation

addCallback()

void PickCallback::addCallback	(	void(*)(void *, SoPath *)	callback,
		void *	userdata )

Adds a callback that will be called when some node is picked.

removeCallback()

handleEvent()

void PickCallback::handleEvent ( SoHandleEventAction * action )

protectedvirtual

Coin method. Checks to see if some child is picked, and triggers callbacks when this happens.

initClass()

static

Required Coin method.

removeCallback()

void PickCallback::removeCallback	(	void(*)(void *, SoPath *)	callback,
		void *	userdata )

Removes a callback.

pickable

SoSFBool PickCallback::pickable

Can be set to FALSE to temporarily disable pick callbacks. Default value is TRUE.

trigger

SoSFTrigger PickCallback::trigger

Will be triggered right after callbacks are called (if any).
