<P>The <TT>Fl_Tile</TT> class lets you resize the children by dragging
|
2001-11-29 22:24:00 +03:00
|
|
|
the border between them:
|
2002-10-30 17:23:16 +03:00

|
|
|

|
2006-11-26 16:48:04 +03:00
|
|
|
<P>For the tiling to work correctly, the children of an
|
|
|
|
|
<TT>Fl_Tile</TT> 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
|
|
|
|
|
<TT>Fl_Tile</TT>.
|
|
|
|
|
|
|
|
|
|
<P><TT>Fl_Tile</TT> 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 <TT>FL_DOWN_BOX</TT> creating the impression of
|
|
|
|
|
"ridges" where the boxes touch. What you see are
|
|
|
|
|
actually two adjacent <TT>FL_DOWN_BOX</TT>'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>
|
|
|
|
|
|
2001-11-29 22:24:00 +03:00
|
|
|
<P><TT>Fl_Tile</TT> allows objects to be resized to zero dimensions.
|
2002-10-30 17:23:16 +03:00
|
|
|
To prevent this you can use the <TT>resizable()</TT> to limit where
|
|
|
|
|
corners can be dragged to.</P>
|
|
|
|
|
|
2001-11-29 22:24:00 +03:00
|
|
|
<P>Even though objects can be resized to zero sizes, they must
|
|
|
|
|
initially have non-zero sizes so the <TT>Fl_Tile</TT> can figure out
|
2002-10-30 17:23:16 +03:00
|
|
|
their layout. If desired, call <TT>position()</TT> after creating the
|
2001-11-29 22:24:00 +03:00
|
|
|
children but before displaying the window to set the borders where you
|
2002-10-30 17:23:16 +03:00
|
|
|
want.</P>

Creates a new <TT>Fl_Tile</TT> widget using the given position, size,

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
|
1999-01-13 22:28:54 +03:00
|
|
|
all the children in the user code. A kludge has been done so the <TT>
|
2001-11-29 22:24:00 +03:00
|
|
|
Fl_Tile</TT> and all of it's children can be automatic (local)
|
|
|
|
|
variables, but you must declare the <TT>Fl_Tile</TT> <I>first</I>, so
|
|
|
|
|
that it is destroyed last.

to_x, to_y)</A></H4>

|
|
|
Drag the intersection at <TT>from_x,from_y</TT> to <TT>to_x,to_y</TT>.
|
|
|
|
|
This redraws all the necessary children.

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 <TT>resizable()</TT> widget is not
|
1999-01-15 01:14:01 +03:00
|
|
|
resized by dragging any borders.
