Assuming you have a horizontal Pack, the Pack will always stretch
vertically. That's what it was designed to do. You can either rewrite
the "resize()" function of Pack, or you can add another group level
inside Pack, for example:
scr = new Fl_Scroll(10, 10, 100, 100);
scr->begin();
pck = new Fl_Pack(10, 10, 100, 100); // fill the scroll
pck->begin();
for (i=0; i<20, ++i) {
grp = new Fl_Group(10+i*20, 10, 20, 100); // this will fill the
Pack
// with invisible widget groups
grp->begin();
img = new Fl_Box(FL_UP_BOX, grp->x(), grp->y(), grp->w(), 50);
// creates 50 pixel high poxes at the top of the group
filler = new Fl_Box(FL_FLAT_BOX, grp->x(), grp->y()+50, grp-
>w(), grp->h()-50);
// creates a filler pieces that does all the resizing
grp->resizable(filler);
// now your img will never change size
grp->end();
}
pck->end();
scr->end();
