Example

This example uses two TaskBar controls. The one lists all commands, the other commands the user wishes to access. This could be used to customise an application. The Hot and Cold BarItem events are used to display a tip related to the hot item. The tip text is stored as the Tag on the BarItem. Clicking on an item in the commands TaskBar moves it to the selected commands TaskBar. Similarly clicking on an item in the selected commands TaskBar moves it to the commands TaskBar.

Note that instead of attaching to the Cold event of each BarItem you can use the ItemCold event of the TaskBar.

The image below shows the Form for this example.
