touch screen events

[ttblue <ashley glenister quill-coding com>]

Using gtk on an embedded unit with a touch screen.

 I would like to boot up my application and if the screen is touched
anywhere be able to see that.
Then I can show a calibration screen.

 My question is how do I get to see the clicks/touches coming in before they
are assigned to an event.

 Or is there some other clever way to skin this cat ?
