Array of Buttons

[Guest_imported]

Hello all ,

I asked about how to do an array of labels and cyprus106
answerd me . Now I need to know how can i make an array of buttons (I think it's exactly equal an array of labels) , but I also need to know how can i put code on the OnClick of one of the array buttons.

TIA

Thor

Try the following - it works for me. It is from c++Builder 5 standard.

all you have to do is make it exactly like the label array and then when you want an OnClick do:

btn->OnClick = MyButtonOnClick;

Dont put in Parenthesis when assigning. just write it like that and that's all there is to it. Make sure to put in the TObject *Sender and Only TObject *Sender in the MyButtonOnClick Parameters.
[i.e. MyButtonOnClick(TObject *Sender)]

Just in case...

Oops, I hate that!. Here, let's try this one again...
