I’ve found myself in the situation where I have a class that needs to keep track of an array of another class but not… directly. Really an array of pointers is exactly what I require because if the value in the array changes somehow then I want that change to be reflected.
If I have 3 Windows and each window has an apple in it, then I have a manager class that knows in each of these windows there is an apple. I cannot simply say:
dim apples(3) as apple
apples(0) = Window1.apple
apples(1) = Window2.apple
apples(2) = Window3.apple
That won’t work, because it creates a copy of the apples. Now the Windows have 3 apples, and the manager has 3 apples too. If Window1’s apple gets eaten by a worm and destroyed, then that has nothing to do with the manager’s first apple because it isn’t the same apple.
I don’t want the manager to have three of his own apples, I want him to have a list of the apples that belong to the windows. He should have NO apples.
Does anyone have a solution?
