The hack approach: declare cards globally and use it as needed.

Fl_Tabs *cards;

void but1_Callback(...) {

cards = new Fl_Tabs(40,40,300,200);

Tried this one quickly and I get a SIGSEV ("Segmentation fault")

As a rider to the previous reply, I'd add that it's probably a good idea to make sure that you "end" window1 before instantiating window2 to avoid getting into weird parenting dependencies between the two windows.

Also, this code would instantiate another window2 every time the button is pressed which might not be the intended behaviour.
