<h2>Detailed Description</h2>

<p>The QStyleHintReturn class provides style hints that return more than basic data types.</p>

<p>QStyleHintReturn and its subclasses are used to pass information from a style back to the querying widget. This is most useful when the return value from <a href="qstyle.html#styleHint">QStyle::styleHint</a>() does not provide enough detail; for example, when a mask is to be returned.</p>

<h2>Member Function Documentation</h2>

<h3 class="fn"><a name="QStyleHintReturn"></a>QStyleHintReturn::QStyleHintReturn ( int <i>version</i> = QStyleOption::Version, int <i>type</i> = SH_Default )</h3>

<p>Constructs a <a href="qstylehintreturn.html">QStyleHintReturn</a> with version <i>version</i> and type <i>type</i>.</p>

<p>The version has no special meaning for <a href="qstylehintreturn.html">QStyleHintReturn</a>; it can be used by subclasses to distinguish between different version of the same hint type.</p>

<p>See also <a href="qstyleoption.html#version-varx">QStyleOption::version</a> and <a href="qstyleoption.html#type-varx">QStyleOption::type</a>.</p>

<hr />

<h2>Member Variable Documentation</h2>

<h3 class="fn"><a name="Type-var"></a>const int QStyleHintReturn::Type</h3>

<p>Equals <a href="qstylehintreturn.html#HintReturnType-enum">SH_Default</a>.</p>

<h3 class="fn"><a name="Version-var"></a>const int QStyleHintReturn::Version</h3>

<p>Equals 1.</p>

<h3 class="fn"><a name="type-varx"></a>int QStyleHintReturn::type</h3>

<p>This variable holds the type of the style hint container.</p>

<p>See also <a href="qstylehintreturn.html#HintReturnType-enum">HintReturnType</a>.</p>

<h3 class="fn"><a name="version-varx"></a>int QStyleHintReturn::version</h3>

<p>This variable holds the version of the style hint return container.</p>

<p>This value can be used by subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast<T>(), you normally don't need to check it.</p>

<h3 class="fn"><a name="qstyleoption_cast-2"></a>T qstyleoption_cast ( const QStyleHintReturn * <i>hint</i> )</h3>

<p>This is an overloaded member function, provided for convenience. It behaves essentially like the above function.</p>

<p>Returns a T or 0 depending on the <a href="qstylehintreturn.html#type-varx">type</a> and <a href="qstylehintreturn.html#version-varx">version</a> of <i>hint</i>.</p>

<p>Example:</p>

<pre>  int MyStyle::styleHint(StyleHint stylehint, const QStyleOption *opt,

const QWidget *widget, QStyleHintReturn* returnData) const;

{

if (stylehint == SH_RubberBand_Mask) {

const QStyleHintReturnMask *maskReturn =

qstyleoption_cast<const QStyleHintReturnMask *>(hint);

if (maskReturn) {
