/**
|
|
The Fl_Tile class lets you resize the children by dragging
|
|
the border between them:
|
|
|
|
<P ALIGN=CENTER>\image html Fl_Tile.png </P>
|
|
\image latex Fl_Tile.png "Fl_Tile" width=4cm
|
|
|
|
<P>For the tiling to work correctly, the children of an
|
|
Fl_Tile must cover the entire area of the widget, but not
|
|
overlap. This means that all children must touch each
|
|
other at their edges, and no gaps can't be left inside the
|
|
Fl_Tile.
|
|
|
|
<P>Fl_Tile does not normailly draw any graphics of its own.
|
|
The "borders" which can be seen in the snapshot above
|
|
are actually part of the children. Their boxtypes have been set
|
|
to FL_DOWN_BOX creating the impression of
|
|
"ridges" where the boxes touch. What you see are
|
|
actually two adjacent FL_DOWN_BOX's drawn next to each
|
|
other. All neighboring widgets share the same edge - the widget's
|
|
thick borders make it appear as though the widgets aren't actually
|
|
touching, but they are. If the edges of adjacent widgets do not
|
|
touch, then it will be impossible to drag the corresponding
|
|
edges.</P>
|
|
|
|
<P>Fl_Tile allows objects to be resized to zero dimensions.
|
|
To prevent this you can use the resizable() to limit where
|
|
corners can be dragged to.</P>
|
|
|
|
<P>Even though objects can be resized to zero sizes, they must
|
|
initially have non-zero sizes so the Fl_Tile can figure out
|
|
their layout. If desired, call position() after creating the
|
|
children but before displaying the window to set the borders where you
|
|
want.
|
|
|
|
<P>Note on resizable(Fl_Widget &w) :
|
|
The "resizable" child widget (which should be invisible) limits where the
|
|
border can be dragged to. If you don't set it, it will be possible to
|
|
drag the borders right to the edge, and thus resize objects on the edge
|
|
to zero width or height. The resizable() widget is not
|
|
resized by dragging any borders. See also void Fl_Group::resizable(Fl_Widget &w)

Creates a new Fl_Tile widget using the given position, size,

<P>The destructor <I>also deletes all the children</I>. This allows a

whole tree to be deleted at once, without having to keep a pointer to
|

all the children in the user code. A kludge has been done so the

Fl_Tile and all of it's children can be automatic (local)

variables, but you must declare the Fl_Tile <I>first</I>, so

that it is destroyed last.
