I believe you can do this the same way you would any FLTK widget
where you want your own resizing behavior:
Derive your own class that overrides the resize() method,
and resize the rows/columns with the logic you like.

No, that sounds perhaps unrelated.
Fl_Table has the concept of interactive resizing of rows
and columns, which is not related to the resizing of the
widget itself. Separate issue.
The widget's docs talk about that, it does not talk about
the widget resizing behavior, which is handled as per the
usual FLTK mechanism involving the resize() method.
The resize() method is what you want to focus on, and like
all FLTK widgets, this method is called when the widget is
being resized, and handles all logic on how the widget
(and its children) deal with being resized.
So if you override this method in your derived class,
take care to call the base class's resize() method
along with your custom logic, so the widget can do
its internal bookkeeping. eg:
class YourClass : public Fl_Table_Row {
..
void resize(int X,int Y,int W,int H) { // your custom override for
resize()
Fl_Table_Row::resize(X,Y,W,H); // call base class's resize()
// your logic here
}
..
};
If you still have trouble, show us a simple, compilable
example of what you've done. (remove all unrelated code of your app)
