You don't need to ask to confirm. You can confirm yourself by trying it.

QStyleOptionViewItemV4' is deprecated , what should be the solution to fix this

compilation terminated.

how to solve these errors

@Qt-Enthusiast
Hi
You can use QStyleOptionViewItem directly.

QCleanlooksStyle is worse. why does app need its includes ?
You can compile the old style plugin by yourself, but now is a good
opportunity to get rid of it. So please tell why app needs it.

Any how, its all explained here
http://doc.qt.io/qt-5/sourcebreaks.html
read Changes to QStyle
It also says how to get it back if needed.

See here: http://doc.qt.io/qt-5/sourcebreaks.html#changes-to-qstyle

"
QFusionStyle is internal. Recommended alternatives:

• QStyleFactory for creating instances of specific styles.
• QProxyStyle for customizing existing style implementations.
• QCommonStyle as a base for implementing full custom styles.

header->setStyle( new QFusionStyle );

header->setStyle( "Fusion" );  // maybe for QApplication only
// or
header->setStyle( new QStyleFactory::create("Fusion" ));

new QStyleFactory::create("Fusion" )
its is not working

can some one point me to a example how Qfusion style is being used in the Qt 5 code

[mpergand]

setStyle(QStyleFactory::create("Fusion")); // without new

For me (OSX), it works only with QApplication, not with QWidget
