Modifies the default state of the canvas where state may be set to one of
- normal
- disabled
- hidden
Individual canvas objects all have their own state option which may override the default state. Many options can take separate specifications such that the appearance of the item can be different in different situations. The options that start with active control the appearence when the mouse pointer is over it, while the option starting with disabled controls the appearence when the state is disabled. Canvas items which are disabled will not react to canvas bindings.
