Can I change the color of button after text change?
Posted: Sun Jul 28, 2019 2:19 pm
I have the folowing code where I have some colored buttons. If I click one of them, a new window pops up and ask for a value. If a value is inserted, then this value is added to the button text, the one which was clicked. All I want is to change button's backcolor after the addition of the value. Is there a way to do it?
Code: Select all
