If the array has one entry, then either NUM must be 1, or you must devise a way to handle missing names, like setting and testing null pointer values in the fixed size array.

QHBoxLayout(3qt)														  QHBoxLayout(3qt)

NAME

       QHBoxLayout - Lines up widgets horizontally

SYNOPSIS

       #include <qlayout.h>

       Inherits QBoxLayout.

   Public Members
       QHBoxLayout ( QWidget * parent, int margin = 0, int spacing = -1, const char * name = 0 )
       QHBoxLayout ( QLayout * parentLayout, int spacing = -1, const char * name = 0 )
       QHBoxLayout ( int spacing = -1, const char * name = 0 )
       ~QHBoxLayout ()

DESCRIPTION

       The QHBoxLayout class lines up widgets horizontally.

       This class is used to construct horizontal box layout objects. See QBoxLayout for more details.

       The simplest use of the class is like this:

	       QBoxLayout * l = new QHBoxLayout( widget );
	       l->setAutoAdd( TRUE );
	       new QSomeWidget( widget );
	       new QSomeOtherWidget( widget );
	       new QAnotherWidget( widget );

       or like this:

	       QBoxLayout * l = new QHBoxLayout( widget );
	       l->addWidget( existingChildOfWidget );
	       l->addWidget( anotherChildOfWidget );

       <center>
								     [Image Omitted]

       </center>

       See also QVBoxLayout, QGridLayout, the Layout overview, Widget Appearance and Style, and Layout Management.

MEMBER FUNCTION DOCUMENTATION

QHBoxLayout::QHBoxLayout ( QWidget * parent, int margin = 0, int spacing = -1, const char * name = 0 )
       Constructs a new top-level horizontal box called name, with parent parent.

       The margin is the number of pixels between the edge of the widget and its managed children. The spacing is the default number of pixels
       between neighboring children. If spacing is -1 the value of margin is used for spacing.

QHBoxLayout::QHBoxLayout ( QLayout * parentLayout, int spacing = -1, const char * name = 0 )
       Constructs a new horizontal box called name name and adds it to parentLayout.

       The spacing is the default number of pixels between neighboring children. If spacing is -1, this QHBoxLayout will inherit its parent's
       spacing().

QHBoxLayout::QHBoxLayout ( int spacing = -1, const char * name = 0 )
       Constructs a new horizontal box called name name. You must add it to another layout.

       The spacing is the default number of pixels between neighboring children. If spacing is -1, this QHBoxLayout will inherit its parent's
       spacing().

QHBoxLayout::~QHBoxLayout ()
       Destroys this box layout.

       The layout's widgets aren't destroyed.
