Unfortunately there is at this moment not an interface for this.
It is the Windows operating system that triggers showing the balloon when the mouse hovers a component and sadly this appears to be the case only for mouse over and for touch there is not a similar concept.
As I explained, there is at this moment not a built-in programmatic triggering of the balloon.
It is the Windows operating system that initiates when the balloon is displayed in relationship with mouse hovering. We will need to investigate if a programmatic trigger is possible.
