focusedNode

Member Function Documentation

void OSGUIsh::FocusPolicy::setFocusedNode

(

NodePtr

focusedNode

)

[inline, protected]

Updates the focused node.

Definition at line 50 of file FocusPolicy.hpp.

References focusedNode_.

virtual void OSGUIsh::FocusPolicy::updateFocus	(	const osgGA::GUIEventAdapter &	ea,
		const NodePtr	nodeUnderMouse
	)		[pure virtual]

Concrete subclasses of FocusPolicy will implement this so that setFocusedNode() is called whenever it is necessary to change the focus according to the policy.

This is called for every event arriving via OSG, after the signals are called.

Parameters:

ea	The event generated by OSG.
nodeUnderMouse	The node under the mouse pointer.

Implemented in OSGUIsh::ManualFocusPolicy, OSGUIsh::MouseDownFocusPolicy, and OSGUIsh::MouseOverFocusPolicy.

Member Data Documentation

NodePtr& OSGUIsh::FocusPolicy::focusedNode_ [private]

A reference to the focused node. The policy will make this point to the proper node, the one that has the focus according to the policy.

Definition at line 58 of file FocusPolicy.hpp.

Referenced by setFocusedNode().
