Description

This widget was designed to add the functionality of compressing and aligning widgets.

If type() is Fl_Pack::HORIZONTAL all the children are resized to the height of the Fl_Pack, and are moved next to each other horizontally. If type() is not Fl_Pack::HORIZONTAL then the children are resized to the width and are stacked below each other. Then the Fl_Pack resizes itself to surround the child widgets.

This widget is needed for the Fl_Tabs. In addition you may want to put the Fl_Pack inside an Fl_Scroll.

Methods

Fl_Pack::Fl_Pack(int x, int y, int w, int h, const char *label = 0)

Creates a new Fl_Pack widget using the given position, size, and label string. The default boxtype is FL_NO_BOX.

virtual Fl_Pack::~Fl_Pack()

The destructor also deletes all the children. 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_Pack and all of it's children can be automatic (local) variables, but you must declare the Fl_Packfirst, so that it is destroyed last.

Fl_Boxtype Fl_Pack::box() const
void Fl_Pack::box(Fl_Boxtype)

Gets or sets the box type for the widget, which identifies a routine that draws the background of the widget. Only frame box types may be used with the Fl_Pack widget.

void Fl_Pack::resizable(Fl_Widget *box)
void Fl_Pack::resizable(Fl_Widget &box)
Fl_Widget *Fl_Pack::resizable() const

The resizable for Fl_Pack is set to NULL by default.

int Fl_Pack::spacing() const
void Fl_Pack::spacing(int)
