bowei zhang, Thank you for the example I got it working. It is working and now when I tap my button the spin box increments. My next question is how do I get the value from the spin box? It is incrementing fine thats not a problem anymore but what will happen is I am going to populate my spin box at startup with a number like 90. I will then use the spin box control to increment it to maybe 95. When I tap on my “Save” button I would like to get the new text value of the spin box so I can save it. I see in the UART instructions there is get_text function but I can’t get that to work either.
Thanks again for all your help.
David
