Change image with a virtual button

It is not exactly clear what kind of information you are looking for.

If you are looking for image loading, have a look at the QImage class.

Hi anda.
I'm sorry, maybe i didn't wrote good what kind of information i need: I would like create a code that translates a buffer of values (the measurement of distance by sensor) to a 1D gesture. but i'don't know how to do it, any suggestion?
I thought to use it to create a program that switch between three or four images with only one 'tap' (the 'tap' is, for example, a decreasing value from my range sensor because i'm bringing my hand closer to the sensor).

I wrote a program that creates a 'led' that change color if i clicked in a button.
I still have the problem of the buffer of values, any ideas about it?

Hmm, so you want to use the sensor data to trigger an event similar to clicking a button?

You will probably need a class that receives the sensor data and then "decides what it sees".

If it detects your "tap" then it emits a signal.
Alternatively it could create an event and send that into the Qt event loop, e.g. QKeyEvent simulating a key press.
