Oh…
I think i'm beginning to understand.
As i mix fluid generated code and my own functions, i receive all
objects as «superclass» Fl_Widget.
Then, i've to ensure i can call specialized methods on them.
// with «Fl_Widget *w»
if (Fl_Select_Browser *b = dynamic_cast<Fl_Select_Browser *>(w)) {
// it usually works , but not this time with Fl_Select_Browser
}
Here, w is still a «Fl_Browser» and cannot be subclassed to
Fl_Select_Browser.
Well, that's what i guess (i'm not a C++ guru even if i try and improve ;) )
Thank you for your help.
