I need to change my widget.newButton’s image after taping on to indicate whether or not a selection was correct or incorrect…

Example :

myBtn = widget.newButton{ &nbsp;&nbsp;&nbsp;&nbsp; id = "myBtn", &nbsp;&nbsp;&nbsp;&nbsp; left = 255, &nbsp;&nbsp;&nbsp;&nbsp; top = 58, &nbsp;&nbsp;&nbsp;&nbsp; width = 44, &nbsp;&nbsp;&nbsp;&nbsp; height = 44, &nbsp;&nbsp;&nbsp;&nbsp; default = "image1.png", &nbsp;&nbsp;&nbsp;&nbsp; over = "image2.png", &nbsp;&nbsp;&nbsp;&nbsp; onEvent = onBtn } &nbsp; -- trying to change image after tap. local onBtn = function( event ) &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (event.target.id == "Y" ) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("Correct....") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; myBtn.default = "correct.png" &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; NextQuestion(appGlobals.CurrentQuestion); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; else &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("Wrong....") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; myBtn.default = "wrong.png" &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end end

Hi @doubleslashdesign,

Once you configure the widget button, you can’t later change (dynamically) what the “default” and “over” images will be. You would need to re-create the button, i.e. put a new one in place of the previous one.

Also, as a quick note, in your code above the “onBtn” function will not be called because it’s out of scope. You declared it as a local function below the widget setup which calls it, so that widget will not be aware of that function at all.

Take care,

Brent
