Detailed Description

This widget simply draws its box, and possibly it's label. Putting it before some other widgets and making it big enough to surround them will let you draw a frame around them.

Constructor & Destructor Documentation

Fl_Box::Fl_Box	(	int	X,
		int	Y,
		int	W,
		int	H,
		const char *	l = 0
	)		[inline]

• The first constructor sets box() to FL_NO_BOX, which means it is invisible. However such widgets are useful as placeholders or Fl_Group::resizable() values. To change the box to something visible, use box(n).
• The second form of the constructor sets the box to the specified box type.

The destructor removes the box.

Member Function Documentation

void Fl_Box::draw

(

)

[protected, virtual]

Draws the widget. Never call this function directly. FLTK will schedule redrawing whenever needed. If your widget must be redrawn as soon as possible, call redraw() instead.

Override this function to draw your own widgets.

If you ever need to call another widget's draw method from within your own draw() method, e.g. for an embedded scrollbar, you can do it (because draw() is virtual) like this:

        Fl_Widget *s = &scroll;         // scroll is an embedded Fl_Scrollbar
        s->draw();                      // calls Fl_Scrollbar::draw()

Implements Fl_Widget.

int Fl_Box::handle

(

int

event

)

[virtual]

Handles the specified event. You normally don't call this method directly, but instead let FLTK do it when the user interacts with the widget.

When implemented in a widget, this function must return 0 if the widget does not use the event or 1 otherwise.

Most of the time, you want to call the inherited handle() method in your overridden method so that you don't short-circuit events that you don't handle. In this last case you should return the callee retval.

Parameters:

[in]

event

the kind of event received

Return values:

0	if the event was not used or understood
1	if the event was used and can be deleted

Reimplemented from Fl_Widget.
