horizontal and vertical resizing policy.</p>
<p>The size policy of a widget is an expression of its willingness
to be resized in various ways, and affects how the widget is
treated by the <a href="layout.html">layout engine</a>. Each widget
returns a QSizePolicy that describes the horizontal and vertical
resizing policy it prefers when being laid out. You can change this
for a specific widget by changing its <a href="qwidget.html#sizePolicy-prop">QWidget.sizePolicy</a>
property.</p>
<p>QSizePolicy contains two independent <a href="qsizepolicy.html#Policy-enum">QSizePolicy.Policy</a> values and
two stretch factors; one describes the widgets's horizontal size
policy, and the other describes its vertical size policy. It also
contains a flag to indicate whether the height and width of its
preferred size are related.</p>
<p>The horizontal and vertical policies can be set in the
constructor, and altered using the <a href="qsizepolicy.html#setHorizontalPolicy">setHorizontalPolicy</a>()
and <a href="qsizepolicy.html#setVerticalPolicy">setVerticalPolicy</a>()
functions. The stretch factors can be set using the <a href="qsizepolicy.html#setHorizontalStretch">setHorizontalStretch</a>()
and <a href="qsizepolicy.html#setVerticalStretch">setVerticalStretch</a>()
functions. The flag indicating whether the widget's <a href="qwidget.html#sizeHint-prop">sizeHint()</a> is width-dependent
(such as a menu bar or a word-wrapping label) can be set using the
<a href="qsizepolicy.html#setHeightForWidth">setHeightForWidth</a>()
function.</p>
<p>The current size policies and stretch factors be retrieved using
the <a href="qsizepolicy.html#horizontalPolicy">horizontalPolicy</a>(),
<a href="qsizepolicy.html#verticalPolicy">verticalPolicy</a>(),
<a href="qsizepolicy.html#horizontalStretch">horizontalStretch</a>() and
<a href="qsizepolicy.html#verticalStretch">verticalStretch</a>()
functions. Alternatively, use the <a href="qsizepolicy.html#transpose">transpose</a>() function to swap the
horizontal and vertical policies and stretches. The <a href="qsizepolicy.html#hasHeightForWidth">hasHeightForWidth</a>()
function returns the current status of the flag indicating the size
hint dependencies.</p>
<p>Use the <a href="qsizepolicy.html#expandingDirections">expandingDirections</a>()
function to determine whether the associated widget can make use of
more space than its <a href="qwidget.html#sizeHint-prop">sizeHint()</a> function indicates, as
well as find out in which directions it can expand.</p>
<p>Finally, the QSizePolicy class provides operators comparing this
size policy to a given policy, as well as a <a href="qvariant.html">QVariant</a> operator storing this QSizePolicy as a
<a href="qvariant.html">QVariant</a> object.</p>

<p>A value of <a href="qt.html#Orientation-enum">Qt.Horizontal</a>

the widget can grow horizontally or vertically (i.e., the
horizontal or vertical policy is <a href="qsizepolicy.html#Policy-enum">Expanding</a> or <a href="qsizepolicy.html#Policy-enum">MinimumExpanding</a>), whereas
<a href="qt.html#Orientation-enum">Qt.Horizontal</a> | <a href="qt.html#Orientation-enum">Qt.Vertical</a> means that it can grow

<p>The control type specifies the type of the widget for which this
size policy applies. It is used by some styles, notably <a href="qmacstyle.html">QMacStyle</a>, to insert proper spacing between
widgets. For example, the Mac OS X Aqua guidelines specify that
push buttons should be separated by 12 pixels, whereas vertically
stacked radio buttons only require 6 pixels.</p>
