The Fl_Tile class lets you resize the children by dragging
38
the border between them:

43
<P>For the tiling to work correctly, the children of an
44
Fl_Tile must cover the entire area of the widget, but not
45
overlap. This means that all children must touch each
46
other at their edges, and no gaps can't be left inside the
49
<P>Fl_Tile does not normailly draw any graphics of its own.
50
The "borders" which can be seen in the snapshot above
51
are actually part of the children. Their boxtypes have been set
52
to FL_DOWN_BOX creating the impression of
53
"ridges" where the boxes touch. What you see are
54
actually two adjacent FL_DOWN_BOX's drawn next to each
55
other. All neighboring widgets share the same edge - the widget's
56
thick borders make it appear as though the widgets aren't actually
57
touching, but they are. If the edges of adjacent widgets do not
58
touch, then it will be impossible to drag the corresponding
61
<P>Fl_Tile allows objects to be resized to zero dimensions.
62
To prevent this you can use the resizable() to limit where
63
corners can be dragged to.</P>
65
<P>Even though objects can be resized to zero sizes, they must
66
initially have non-zero sizes so the Fl_Tile can figure out
67
their layout. If desired, call position() after creating the
68
children but before displaying the window to set the borders where you
71
<P>Note on resizable(Fl_Widget &w) :
72
The "resizable" child widget (which should be invisible) limits where the
73
border can be dragged to. If you don't set it, it will be possible to
74
drag the borders right to the edge, and thus resize objects on the edge
75
to zero width or height. The resizable() widget is not
76
resized by dragging any borders. See also void Fl_Group::resizable(Fl_Widget &w)
79
class FL_EXPORT Fl_Tile : public Fl_Group {
83
Creates a new Fl_Tile widget using the given position, size,
84
and label string. The default boxtype is FL_NO_BOX.
86
<P>The destructor <I>also deletes all the children</I>. This allows a
87
whole tree to be deleted at once, without having to keep a pointer to
88
all the children in the user code. A kludge has been done so the
89
Fl_Tile and all of it's children can be automatic (local)
90
variables, but you must declare the Fl_Tile <I>first</I>, so
91
that it is destroyed last.
