After having peeked at the source for Fl_Tile.cxx, I came up with this:
class Fl_Vertical_Tile : public Fl_Tile
{
public:
Fl_Vertical_Tile(int X, int Y, int W, int H, const char *L = 0)
: Fl_Tile(X, Y, W, H, L)
{}
void resize(int X, int Y, int W, int H)
{
int old_w = w();
int old_h = h();
Fl_Tile::resize(X,Y,W,H);
if(children() && (old_w < W || old_h < H))
{
Fl_Widget *o = child(children()-1);
int dw = 0; /*(W - old_w); // causes veritcally stacked widgets
to widen strangly*/
int dh = (H - old_h);
o->damage_resize(o->x(), o->y(), o->w() + dw, o->h() + dh);
}
}
};
My limited testing has shown that this only works when the tile consists of
vertically stacked widgets who's width spans the Fl_Tile.
Basically, what this does is after the Fl_Tile has been resized, it attempts
to grow the last child so that it consumes any free realestate (e.g. dh).
What I'm not sure of is: why that when the Fl_Tile is resized width-wise
only, is that applying the change in width (dw) to the last child's current
width causes the last child to grow beyond the width of the Fl_Tile?
