<h3>Description</h3>
|
|
|
|
The <tt>Fl_Tile</tt> class lets you resize the children by dragging the
|
|
border between them:
|
|
|
|
<p><img src=Fl_Tile.gif>
|
|
|
|
<p><tt>Fl_Tile</tt> allows objects to be resized to zero dimensions.
|
|
To prevent this you can use the <tt>resizable()</tt> to limit where
|
|
corners can be dragged to.
|
|
|
|
<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
|
|
their layout. If desired, call <tt>position()</tt> after creating the
|
|
children but before displaying the window to set the borders where you
|
|
want.
|
|
|
|
<p>The "borders" are part of the children, an <tt>Fl_Tile<tt> does not
|
|
draw any graphics of it's own. In the above example all the final
|
|
children have <tt>FL_DOWN_BOX</tt> types, and the "ridges" you see are
|
|
two adjacent <tt>FL_DOWN_BOX</tt>'s drawn next to each other.
|
|

<h4><a name="Fl_Tile.Fl_Tile">Fl_Tile::Fl_Tile(int x, int y, int w, int h, const char *label = 0)</a></h4>
|
|
|
|
Creates a new <tt>Fl_Tile</tt> widget using the given position, size, and
|
|
label string. The default boxtype is <tt>FL_NO_BOX</tt>.
|
|
|
|
<h4><a name="Fl_Tile.~Fl_Tile">virtual Fl_Tile::~Fl_Tile()</a></h4>
|
|
|
|
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
|
|
<tt>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.
|
|
|
|
<h4><a name="Fl_Tile.position">void Fl_Tile::position(from_x, from_y, 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.
|
|
|
|
<h4><a name="Fl_Tile.resizeable">void Fl_Tile::resizable(Fl_Widget&)</a></h4>
|
|
|
|
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
|
|
resized by dragging any borders.
