Method onCheckBoxChecked

Gui/MultiInstancePanel.cpp:1414–1453

The checkbox interacts directly with the kDisableNodeKnobName knob of the node It doesn't call deactivate() on the node so calling isActivated() on a node will still return true even if you set the value of kDisableNodeKnobName to false.
