I would like to have a matriz of buttons where I can use all of this buttons. I tried someting like this (first print), but it doesn't work because I can use . in this type of variables.
I tried other option, which is in the second foto. This works and do what I want. It creates a matrix of buttons. But then, in other functions, I want to disable all of the buttons and I can't do it because I can't use an array, like in the first foto. Is there a way to use an array of buttons like in my first foto?
One example is my third foto. I want to disable all of the buttons in a for cicle, but it doesn't work because I can't use the array. In my code, if my matrix was 3x3, it only disable the last button (last image).
I wish I explain well what is my problem.
