I made a custom slot for when one of my buttons get clicked on. When this button is clicked, it is to access some other buttons and change some of their properties like setText etc.

I finally managed to get my button connected with the slot, but I can't figure out how to access the button from the slot. I tried passing the button, passing it by reference, and passing a pointer, but anytime I try to pass something it fails to connect the slot. Here is my current code without passing anything. This is just a test that I've been playing around with.

I might add that I am a complete newbie at this. I have a programming assignment due Friday that is to make a minesweeper game, so I have a week to learn enough Qt to make it work. I had never even heard of Qt until 2 days ago. What I really need to do is add a unique id to each button so I can access them like that, but I figured I needed to know how to get the slot working first.

Any help or tips would be much appreciated, Thanks!
