The fastest way is to derive your own group and override the default
resize method:
class myGroup: public Fl_Group
{
public:
myGroup(int X, int Y, int W, int H,const char*
L=""):Fl_Group(X,Y,W,H,L) {}
void resize(int X, int Y, int W, int H)
{ // first resize as usual
Fl_Group::resize(X,Y,W,H);
// now make sure that the console is not smaller than the minimal
// height by resizing tree and viewer accordingly
if (...) {...}
}
};
That should do the trick.
