<h2>Detailed Description</h2>
<p>The QProxyStyle class is a convenience class that simplifies dynamically overriding <a href="qstyle.html">QStyle</a> elements.</p>
<p>A QProxyStyle wraps a <a href="qstyle.html">QStyle</a> (usually the default system style) for the purpose of dynamically overriding painting or other specific style behavior.</p>
<p>The following example shows how to override the shortcut underline behavior on any platform:</p>
<pre> #include "textedit.h"
#include <QApplication>
#include <QProxyStyle>
class MyProxyStyle : public QProxyStyle
{
public:
int styleHint(StyleHint hint, const QStyleOption *option = 0,
const QWidget *widget = 0, QStyleHintReturn *returnData = 0) const
{
if (hint == QStyle::SH_UnderlineShortcut)
return 0;
return QProxyStyle::styleHint(hint, option, widget, returnData);
}
};
int main(int argc, char **argv)
{
Q_INIT_RESOURCE(textedit);
QApplication a(argc, argv);
a.setStyle(new MyProxyStyle);
TextEdit mw;
mw.resize(700, 800);
mw.show();
<span class="comment">//...</span>
}</pre>
<p>Warning: The <a href="qcommonstyle.html">common styles</a> provided by Qt will respect this hint, because they call <a href="qstyle.html#proxy">QStyle::proxy</a>(), but there is no guarantee that <a href="qstyle.html#proxy">QStyle::proxy</a>() will be called for user defined or system controlled styles. It would not work on a Mac, for example, where menus are handled by the operating system.</p>
