• escape: 
  • invoked when the Esc key is pressed
  • the function should return true if the event was "consumed", false otherwise
  • typically the function in the business logic will maintain state as to whether there is anything to "clear" / "reset", and use that to decide whether Esc should be consumed or not
  • Some example code:

    • Code Block
      language js collapse true
      // Sample code in the Business Logic   // "constants" var startDisplay = 'sampleDemoStartDisplay', stopDisplay = 'sampleDemoStopDisplay';   // internal state var active = false;   ...   function startDisplay() { if (!active) { active = true; wss.sendEvent(startDisplay); } }   // returns true if display was stopped; false if already stopped function stopDisplay() { if (!active) { return false; } active = false; wss.sendEvent('stopDisplay'); return true; }

• empty: invoked when the topology node selection changes to "nothing selected"
• single: invoked when the topology node selection changes to "a single node selected" (either a device or a host)
  • the data parameter is the data model for the selected device
• multi: invoked when the topology node selection changes to "more than one node selected" (may be a combination of devices and hosts)
  • the selectOrder parameter is an array of node IDs in the order that they were selected by the user
