I guess it may have something to do with the main Fl_Double_Window layout
that I have. I have a several Fl_Group widgets and one Fl_Tile. The Fl_Tile
is not set to be resizable. I have the resizable widget set to the Fl_Group
that is the same height and to the left of the Fl_Tile. When I resize the
Fl_Double_Window all the groups grow according to how the left group grows.
The Fl_Tile appears not to grow. However, I can see from the printf
statements in the Fl_MyTile (initial post) that it was in fact growing.
The issue for me was that the children of the Fl_Tile were not growing along
with the Fl_Tile. The Fl_Vertical_Tile that I posted attempts to resize the
last child widget so that it consumes the new free space.
I will need to review the tile example and do some more testing. I have a
feeling that this is a design issue on my part. I may not be using the
Fl_Tile correctly.
