.SH MEMBER FUNCTION DOCUMENTATION
.SH "QVBoxLayout::QVBoxLayout ( QWidget * parent, int margin = 0, int spacing = -1, const char * name = 0 )"
Constructs a new top-level vertical box with parent \fIparent\fR and name \fIname\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 "QVBoxLayout::QVBoxLayout ( QLayout * parentLayout, int spacing = -1, const char * name = 0 )"
Constructs a new vertical box with the 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 QVBoxLayout will inherit its parent's spacing().
.SH "QVBoxLayout::QVBoxLayout ( int spacing = -1, const char * name = 0 )"
Constructs a new vertical box with the 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 QVBoxLayout will inherit its parent's spacing().
.SH "QVBoxLayout::~QVBoxLayout ()"
Destroys this box layout.
