Answer 1

Hand::street1.colorBet="Red"; & the others are illegal because Hand::street1 isn’t a static class member (I’m not saying it should, having static members should be a logic decision, not something you do to make the code compile).

What Hand object are you attempting to modify in, say, street1BetRedClicked? Do you have any Hand objects? Do you need any Hand objects? Do you create them in that method? Outside?

I pointed out the error, but it seems to me that the important issue here isn’t the fact that the code doesn’t compile, but that:

1. You don’t seem to have a firm grasp on C++, perhaps you should start with something simpler.

2. You don’t have a clear logic set up.
