[fltk.general] Fl_Scroll issue?

[testalucida]

Hi,

seems as if widgets placed onto a Fl_Scroll don't keep their positions on 
scrolling.
E.g.: the topmost widget's y-position is 30. There is a vertical scrollbar due 
to another widget with y-position 300.
Pull the vertical scrollbar down and move it back to its top position. The 
y-value of the topmost widget will be 0. I would expect it keeping its original 
value. Am I wrong or is FLTK?

Here's my code. OS is Linux Mint 12, FLTK 1.3.0.

#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_Group.H>
#include <FL/Fl_Scroll.H>
#include <FL/fl_draw.H>
#include <FL/Fl_Box.H>

class Box : public Fl_Box {
public:
        Box( int x, int y, int w, int h, const char *lbl ) :
                Fl_Box( x, y, w, h, lbl )
        {
                labelcolor( FL_BLACK );
        }

protected:
        void draw() {
                Fl_Box::draw();
                fl_draw_box(FL_UP_BOX, x(), y(), w(), h(), FL_YELLOW );
        }
};

int main() {
Fl_Double_Window *pWin = new Fl_Double_Window( 100, 100, 300, 300, "Scroll 
Tests" );
        pWin->box( FL_NO_BOX );

        Fl_Scroll scroll( 0, 0, 300, 300 );
        scroll.box( FL_DOWN_BOX );

        Box box1( 0, 30, 100, 50, "BOX1" );
        Box box2( 300, 300, 100, 50, "BOX2" );
        scroll.end();

        pWin->end();

        pWin->resizable( scroll );

        pWin->show();

        return Fl::run();
}
