Comments

An action must be added to a container before it can be assigned to a mouse button. To add an action to a container call LImageViewer::AddAction.

If an action is set to a mouse button that is already used by another action, the new action will overwrite the old one.

Actions can also be associated with keystroke combinations. To assign an action to a keystroke combination, call LImageViewer::SetKeyboardAction.
