Comments

The same action cannot be added to a container twice.

To set or get the properties of a specific action, use LImageViewerCell::SetActionProperties and LImageViewerCell::GetActionProperties.

Once an action has been added to the container, it can be associated with a particular mouse movement, a keystroke combination, or both. To associate an action with the mouse, call LImageViewerCell::SetAction. To associate an action with a keystroke combination, call LImageViewerCell::SetKeyboardAction.
