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

.SH MEMBER FUNCTION DOCUMENTATION
.SH "QHBoxLayout::QHBoxLayout ( QWidget * parent, int margin = 0, int spacing = -1, const char * name = 0 )"
Constructs a new top-level horizontal box called \fIname\fR, with parent \fIparent\fR.
.PP
The \fImargin\fR is the number of pixels between the edge of the widget and its managed children. The \fIspacing\fR is the default number of pixels between neighboring children. If \fIspacing\fR is -1 the value of \fImargin\fR is used for \fIspacing\fR.
.SH "QHBoxLayout::QHBoxLayout ( QLayout * parentLayout, int spacing = -1, const char * name = 0 )"
Constructs a new horizontal box called name \fIname\fR and adds it to \fIparentLayout\fR.
.PP
The \fIspacing\fR is the default number of pixels between neighboring children. If \fIspacing\fR is -1, this QHBoxLayout will inherit its parent's spacing().
.SH "QHBoxLayout::QHBoxLayout ( int spacing = -1, const char * name = 0 )"
Constructs a new horizontal box called name \fIname\fR. You must add it to another layout.
.PP
The \fIspacing\fR is the default number of pixels between neighboring children. If \fIspacing\fR is -1, this QHBoxLayout will inherit its parent's spacing().
.SH "QHBoxLayout::~QHBoxLayout ()"
Destroys this box layout.
.PP
The layout's widgets aren't destroyed.
