Manages the actions in a project.
Clients can register for events related to the actions. The events supported by the listener interface are:
def action_added(self, action): def action_moved(self, action): def action_removed(self, action): def channel_added(self, source, dest): def channel_removed(self, source, dest):

| __fire(self, signal, *args) Fires the given event to all listeners [Source] | |
| add_action(self, action) Adds the given action to this project [Source] | |
| move_action(self, action, x, y) Moves the given action to the given screen coordinates [Source] | |

| remove_channel(self, source, dest) Removes a "channel" between two actions. [Source] | |
| action_changed(self, action) Indicates that the given action has changed, so that listeners can update themselves [Source] | |
| check_name(self, action) Checks the name, and renames if necessary [Source] | |
| is_valid_channel(self, source, dest) Returns true if the given source-dest pair would form a valid channel. [Source] | |
| Operation Details: |
Returns the list of actions in this project Actions. The list returned should be considered read-only
Returns the Action object by name. This method uses a dictionary lookup so should be preferred to iteration. Returns None if the name is not found.
Adds a listener to this Projec Actions' events. The listener may implement any of the supported methods and will receive those events.
Adds a "channel" between two actions. Causes the output of the first to be connected to the input of the second. The event 'channel_added' is fired.
Removes a "channel" between two actions. If the channel doesn't exist, it is silently ignored. The event 'channel_removed' is fired.
Returns true if the given source-dest pair would form a valid channel. Invalid pairs (eg: formatter->formatter) return false. Cyclic channels are also disallowed.
