How to change menu's icon's size
-
If you are using QToolBar, it has a iconSize property. For menu, though, refer "link here":http://www.qtcentre.org/threads/15742-How-to-change-Icon-size-in-QMenu
-
AFAIK QMenu only gets it's icon size from the style it has set.
So you would need to subclass "QProxyStyle":http://qt-project.org/doc/qt-4.8/qproxystyle.html#details and reimplement pixelMetric() method:Something like this:
@
class MyProxyStyle : public QProxyStyle
{
public:
int pixelMetric(PixelMetric metric, const QStyleOption * option = 0, const QWidget * widget = 0 ) const
{
if (metric == QStyle::PM_SmallIconSize)
return 32;
else
return QProxyStyle::pixelMetric(metric, option, widget);
};
@
Haven't tried it though.Please also note the hint in the docs:

Warning: The common styles provided by Qt will respect this hint, because they call QStyle::proxy(), but there is no guarantee that QStyle::proxy() 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.

ya,i try your code.it can change icon's size,but when icon's size get big,the QMenu'icon can covered QMenu's text,how to set space
between icon and text.
i find a stylesheet's code ,QMenu::item { padding: xx xx xx xx;},it can change space bewteen icon and text. it can use code instead of stylesheet?
