.SH DESCRIPTION
The QLayoutItem class that represents blank space.
.PP
For custom layouts.
.PP
See also QLayout.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QSpacerItem::QSpacerItem ( int w, int h, QSizePolicy::SizeType hData=QSizePolicy::Minimum=QSizePolicy::Minimum, QSizePolicy::SizeType vData= QSizePolicy::Minimum= QSizePolicy::Minimum )"
Constructs a spacer item with preferred width \fIw,\fR preferred height \fIh,\fR horizontal size policy \fIhData\fR and vertical size policy \fIvData.\fR
.PP
The default values gives a gap that is able to stretch, if nothing else wants the space.
.SH "void QSpacerItem::changeSize ( int w, int h, QSizePolicy::SizeType hData=QSizePolicy::Minimum, QSizePolicy::SizeType vData=QSizePolicy::Minimum )"
Changes this spacer item to have preferred width \fIw,\fR preferred height \fIh,\fR horizontal size policy \fIhData\fR and vertical size policy \fIvData.\fR
.PP
The default values gives a gap that is able to stretch, if nothing else wants the space.
.SH "QSizePolicy::ExpandData QSpacerItem::expanding() const \fC[virtual]\fR"
Returns whether this space item is expanding.
.PP
Reimplemented from QLayoutItem.
.SH "QRect QSpacerItem::geometry () const \fC[virtual]\fR"
Reimplemented for internal reasons; the API is not affected.
.PP
Reimplemented from QLayoutItem.
.SH "bool QSpacerItem::isEmpty () const \fC[virtual]\fR"
Returns TRUE, since a space item never contains widgets.
.PP
Reimplemented from QLayoutItem.
.SH "QSize QSpacerItem::maximumSize () const \fC[virtual]\fR"
Returns the maximum size of this space item.
.PP
Reimplemented from QLayoutItem.
.SH "QSize QSpacerItem::minimumSize () const \fC[virtual]\fR"
Returns the minimum size of this space item.
.PP
Reimplemented from QLayoutItem.
.SH "void QSpacerItem::setGeometry ( const QRect & r ) \fC[virtual]\fR"
This function stores \fIr,\fR so it can be returned by geometry().
.PP
Reimplemented from QLayoutItem.
.SH "QSize QSpacerItem::sizeHint () const \fC[virtual]\fR"
Returns the preferred size of this space item.
.PP
Reimplemented from QLayoutItem.
.SH "QSpacerItem * QSpacerItem::spacerItem () \fC[virtual]\fR"
Reimplemented for internal reasons; the API is not affected.
.PP
