<h3 class=fn>void <a name="addLayout"></a>QBoxLayout::addLayout ( <a href="qlayout.html">QLayout</a>&nbsp;*&nbsp;layout, int&nbsp;stretch = 0 )
</h3>
Adds <em>layout</em> to the end of the box, with serial <a href="layout.html#stretch-factor">stretch factor</a>
<em>stretch</em>.
<p> <p>See also <a href="#insertLayout">insertLayout</a>(), <a href="qlayout.html#setAutoAdd">setAutoAdd</a>(), <a href="#addWidget">addWidget</a>() and <a href="#addSpacing">addSpacing</a>().

<p>Examples: <a href="tutorial2-09.html#x2535">chart/optionsform.cpp</a>, <a href="tutorial2-08.html#x2499">chart/setdataform.cpp</a>, <a href="simple-qfont-demo-walkthrough.html#x2107">fonts/simple-qfont-demo/viewer.cpp</a>, <a href="listbox-example.html#x1305">listbox/listbox.cpp</a> and <a href="tictac-example.html#x115">tictac/tictac.cpp</a>.
<h3 class=fn>void <a name="addSpacing"></a>QBoxLayout::addSpacing ( int&nbsp;size )
</h3>
Adds a non-stretchable space with size <em>size</em> to the end of this
box layout. QBoxLayout provides default margin and spacing. This
function adds additional space.
<p> <p>See also <a href="#insertSpacing">insertSpacing</a>() and <a href="#addStretch">addStretch</a>().

<p>Example: <a href="listbox-example.html#x1306">listbox/listbox.cpp</a>.
<h3 class=fn>void <a name="addStretch"></a>QBoxLayout::addStretch ( int&nbsp;stretch = 0 )
</h3>
Adds a stretchable space with zero minimum size and <a href="layout.html#stretch-factor">stretch factor</a>
<em>stretch</em> to the end of this box layout.
<p> <p>See also <a href="#addSpacing">addSpacing</a>().

<p>Examples: <a href="layout-example.html#x479">layout/layout.cpp</a>, <a href="listbox-example.html#x1307">listbox/listbox.cpp</a> and <a href="tutorial1-13.html#x2397">t13/gamebrd.cpp</a>.
<h3 class=fn>void <a name="addStrut"></a>QBoxLayout::addStrut ( int&nbsp;size )
</h3>
Limits the perpendicular dimension of the box (e.g. height if the
box is LeftToRight) to a minimum of <em>size</em>. Other constraints may
increase the limit.

<h3 class=fn>void <a name="addWidget"></a>QBoxLayout::addWidget ( <a href="qwidget.html">QWidget</a>&nbsp;*&nbsp;widget, int&nbsp;stretch = 0, int&nbsp;alignment = 0 )
</h3>
Adds <em>widget</em> to the end of this box layout, with a <a href="layout.html#stretch-factor">stretch factor</a> of <em>stretch</em> and alignment <em>alignment</em>.
<p> The stretch factor applies only in the <a href="#direction">direction</a> of the QBoxLayout, and is relative to the other boxes and
widgets in this QBoxLayout. Widgets and boxes with higher stretch
factors grow more.
<p> If the stretch factor is 0 and nothing else in the QBoxLayout has
a stretch factor greater than zero, the space is distributed
according to the QWidget:sizePolicy() of each widget that's
involved.
<p> Alignment is specified by <em>alignment</em> which is a bitwise OR of <a href="qt.html#AlignmentFlags-enum">Qt::AlignmentFlags</a> values. The default alignment is 0, which means
that the widget fills the entire cell.
<p> From Qt 3.0, the <em>alignment</em> parameter is interpreted more
aggressively than in previous versions of Qt. A non-default
alignment now indicates that the widget should not grow to fill
the available space, but should be sized according to <a href="#sizeHint">sizeHint</a>().
