Received Events

Plugins can receive events from the Stream Dock application.

Once the Stream Dock application has loaded a plugin and the user has set up some keys to use the plugin, the plugin will receive various events. Similarly, when the Property Inspector is displayed, it will receive some events.

Both plugins and Property Inspectors can receive the following events:

Event	Description
didReceiveSettings	Event received after settings change
didReceiveGlobalSettings	Event received after globalSettings change

Plugins may also receive the following additional events:

keyDown	Event received when a user presses a key
keyUp	Event received when a user releases a key
dialDown	Event received when a user presses a dial
dialUp	Event received when a user releases a pressed dial
dialRotate	Event received when a user rotates a dial
willAppear	Event received when an action instance appears on the Stream Dock (e.g., when hardware is first inserted or when entering a folder containing the action)
willDisappear	Event received when an action instance no longer appears on the Stream Dock (e.g., when switching profiles or folders)
titleParametersDidChange	Event received when the user changes the title or title parameters
deviceDidConnect	Event received when a device is inserted into the computer
deviceDidDisconnect	Event received when a device is removed from the computer
applicationDidLaunch	Event received when a monitored application is launched
