Description

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

If type() is FL_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_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_Tab. In addition you may want to put the Fl_Pack inside an Fl_Scroll.

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.

int Fl_Pack::spacing() const

void Fl_Pack::spacing(int)

Gets or sets the number of extra pixels of blank space that are added between the children.
