If your exclusive app accepts input from mouse devices, you should display a cursor whenever a mouse is plugged into the Xbox One console. You might also choose to hide the cursor when the mouse is unplugged. This topic explains how to programmatically determine whether a mouse device is currently connected to an Xbox One console.
Check the Boolean value of the MouseCapabilities.MousePresent property, as shown in the following example.
C++
_mouCaps = ref new MouseCapabilities();
if(_mouCaps->MousePresent)
{
// A mouse is plugged into the Xbox One console.
}
