<h3 class="fn"><a name="QLayout-4"></a>QLayout::QLayout ( <a href="qwidget.html">QWidget</a> * <i>parent</i>, int <i>margin</i>, int <i>spacing</i> = -1, const char * <i>name</i> = 0 )</h3>
<p>Constructs a new top-level <a href="qlayout.html">QLayout</a> called <i>name</i>, with parent widget <i>parent</i>. <i>parent</i> may not be 0.</p>
<p>The <i>margin</i> is the number of pixels between the edge of the widget and the managed children. The <i>spacing</i> sets the value of <a href="qlayout.html#spacing-prop">spacing</a>(), which gives the spacing between the managed widgets. If <i>spacing</i> is -1 (the default), spacing is set to the value of <i>margin</i>.</p>
<p>There can be only one top-level layout for a widget. It is returned by <a href="qwidget.html#layout">QWidget::layout</a>()</p>
<p>See also <a href="qwidget.html#setLayout">QWidget::setLayout</a>().</p>
<h3 class="fn"><a name="QLayout-5"></a>QLayout::QLayout ( QLayout * <i>parentLayout</i>, int <i>spacing</i> = -1, const char * <i>name</i> = 0 )</h3>
<p>Constructs a new child <a href="qlayout.html">QLayout</a> called <i>name</i>, and places it inside <i>parentLayout</i> by using the default placement defined by <a href="qlayout.html#addItem">addItem</a>().</p>
<p>If <i>spacing</i> is -1, this <a href="qlayout.html">QLayout</a> inherits <i>parentLayout</i>'s <a href="qlayout.html#spacing-prop">spacing</a>(), otherwise the value of <i>spacing</i> is used.</p>
<h3 class="fn"><a name="QLayout-6"></a>QLayout::QLayout ( int <i>spacing</i>, const char * <i>name</i> = 0 )</h3>
<p>Constructs a new child <a href="qlayout.html">QLayout</a> called <i>name</i>. If <i>spacing</i> is -1, this <a href="qlayout.html">QLayout</a> inherits its parent's <a href="qlayout.html#spacing-prop">spacing</a>(); otherwise the value of <i>spacing</i> is used.</p>
<p>This layout has to be inserted into another layout before geometry management will work.</p>
<a name="//apple_ref/cpp/instm/QLayout/add"></a>
<h3 class="fn"><a name="add"></a>void QLayout::add ( <a href="qwidget.html">QWidget</a> * <i>widget</i> )</h3>
<p>Use addWidget(<i>widget</i>) instead.</p>
<a name="//apple_ref/cpp/instm/QLayout/autoAdd"></a>
<h3 class="fn"><a name="autoAdd"></a>bool QLayout::autoAdd () const</h3>
<p>Automatically adding widgets is deprecated. Use <a href="qlayout.html#addWidget">addWidget</a>() or addLayout() instead.</p>
<p>See also <a href="qlayout-qt3.html#setAutoAdd">setAutoAdd</a>().</p>
<a name="//apple_ref/cpp/instm/QLayout/defaultBorder"></a>
<h3 class="fn"><a name="defaultBorder"></a>int QLayout::defaultBorder () const</h3>
<p>Use <a href="qlayout.html#spacing-prop">spacing</a>() instead.</p>
<a name="//apple_ref/cpp/instm/QLayout/deleteAllItems"></a>
<h3 class="fn"><a name="deleteAllItems"></a>void QLayout::deleteAllItems () <tt> [protected]</tt></h3>
<p>Removes and deletes all items in this layout.</p>
<a name="//apple_ref/cpp/instm/QLayout/freeze"></a>
<h3 class="fn"><a name="freeze"></a>void QLayout::freeze ( int <i>w</i> = 0, int <i>h</i> = 0 )</h3>
<p>Sets this layout's parent widget to a fixed size with width <i>w</i> and height <i>h</i>, stopping the user from resizing it, and also prevents the layout from resizing it, even if the layout's size hint should change. Does nothing if this is not a top-level layout (i.e., if <a href="qobject.html#parent">parent</a>()-><a href="qobject.html#isWidgetType">isWidgetType</a>()).</p>
<p>As a special case, if both <i>w</i> and <i>h</i> are 0, then the layout's current <a href="qlayoutitem.html#sizeHint">sizeHint</a>() is used.</p>
<p>Use <tt>setResizeMode(Fixed)</tt> to stop the widget from being resized by the user, while still allowing the layout to resize it when the <a href="qlayoutitem.html#sizeHint">sizeHint</a>() changes.</p>
<p>Use <tt>setResizeMode(FreeResize)</tt> to allow the user to resize the widget, while preventing the layout from resizing it.</p>
<a name="//apple_ref/cpp/instm/QLayout/isTopLevel"></a>
<h3 class="fn"><a name="isTopLevel"></a>bool QLayout::isTopLevel () const</h3>
<p>Returns true if this layout is a top-level layout, i.e. not a child of another layout; otherwise returns false.</p>
<a name="//apple_ref/cpp/instm/QLayout/iterator"></a>
<h3 class="fn"><a name="iterator"></a>QLayoutIterator QLayout::iterator ()</h3>
<p>Use a <a href="porting4.html#qlayoutiterator">QLayoutIterator</a>() constructor instead.</p>
<a name="//apple_ref/cpp/instm/QLayout/mainWidget"></a>
<h3 class="fn"><a name="mainWidget"></a><a href="qwidget.html">QWidget</a> * QLayout::mainWidget () const</h3>
<p>Use <a href="qlayout.html#parentWidget">parentWidget</a>() instead.</p>
<a name="//apple_ref/cpp/instm/QLayout/remove"></a>
<h3 class="fn"><a name="remove"></a>void QLayout::remove ( <a href="qwidget.html">QWidget</a> * <i>widget</i> )</h3>
<p>Use removeWidget(<i>widget</i>) instead.</p>
<a name="//apple_ref/cpp/instm/QLayout/resizeMode"></a>
<h3 class="fn"><a name="resizeMode"></a><a href="qlayout.html#SizeConstraint-enum">SizeConstraint</a> QLayout::resizeMode () const</h3>
<p>Use <a href="qlayout.html#sizeConstraint-prop">sizeConstraint</a>() instead.</p>
<p>See also <a href="qlayout-qt3.html#setResizeMode">setResizeMode</a>().</p>
<a name="//apple_ref/cpp/instm/QLayout/setAutoAdd"></a>
<h3 class="fn"><a name="setAutoAdd"></a>void QLayout::setAutoAdd ( bool <i>a</i> )</h3>
<p>Automatically adding widgets is deprecated. Use <a href="qlayout.html#addWidget">addWidget</a>() or addLayout() instead.</p>
<p>See also <a href="qlayout-qt3.html#autoAdd">autoAdd</a>().</p>
<a name="//apple_ref/cpp/instm/QLayout/setResizeMode"></a>
<h3 class="fn"><a name="setResizeMode"></a>void QLayout::setResizeMode ( <a href="qlayout.html#SizeConstraint-enum">SizeConstraint</a> <i>constraint</i> )</h3>
<p>Use setSizeConstraint(<i>constraint</i>) instead.</p>
