Override this method to do the work of changing the cursor of the device.

Called right after this session is created.

This method has full control over the cursor until the dispose call, and can make system calls to change the pointer cursor as many times as necessary (usually through SystemChannels.mouseCursor). It can also collect resources, and store the result in this object.
