toolTip not showing up

The toolTip is only displayed if a Bubble object (https://api.daypilot.org/daypilot-scheduler-bubble/) is not specified. In the current DayPilot Pro version, the bubble is initialized using a new DayPilot.Bubble object by default.

There are two options:

1. Set dp.bubble to null to activate the tooltip:

var dp = new DayPilot.Scheduler("dp", {
  // ...
  bubble: null,
  //...
});

2. Use bubbleHtml instead of toolTip in the event data object. This will use the bubble to display the additional information on hover. This may be a better solution - the bubble supports HTML and its behavior can be customized (popup delay, appearance, animation...).

dp.events.list = [
  {
    // ...
    bubbleHtml:'Michael Meyers - SENG 6247 - 601 - SENG6247-Final Exam'
  }
];
