In some scenarios, you might want your presentation to sit at a blank screen. The Event Handler fills the role of an empty placeholder in your presentation. Here are a few cases where an Event Handler would be useful:
- You want a blank screen for a Home Screen so no content will play until the presentation is activated.
- You want to add a command that is performed before the first file in the presentation plays.
- You want the presentation to sit at a blank screen when finished, instead of looping.
Although Event Handlers contain no content, you can add commands and interactive events into and out of them. For example, if you set an Event Handler state as the Home Screen and define a BP900 event linked from the Event Handler state to the first presentation item, the display will sit at a blank screen until a user presses the BP900 button, and then the first item will begin playing. Alternatively, if you set an Event Handler as the Home Screen and add a Synchronize command to it, you can synchronize your presentations and/or displays before the first files begin playing.
To use an Event Handler, click the Other tab under Media Library and drag the icon into the playlist area.
- State Name: Enter a unique name for the Media Handler state.
- Stop Playback: Check this box if you would like audio/video playback to end once a media file transitions to the Event Handler state. If this box is left unchecked, audio/video playback will continue after a transition to the Event Handler state.
- Set as initial state: Check this box to make the Event Handler the Home State of the presentation.
Define interactive events into and out of the Event Handler as you would with any other state. If you define a Media End event after a video and link it to an Event Handler, the presentation will sit at a blank screen when the file finishes playing.
