Must I include each widget header with qt5?

[aguayro]

It's works, its fastr if only include the used widgets.

I'm having another battle now, with the styles. Seems something has changed, can't include none of QWidowsVistaStyle, QPlastiqueStyle, etc... tryed QFusionStyle but doesn't exist.
I've been googling for Qt5 Style system changes but nothing found. Some information on qt blog about "cleaning styles" and fusion style, but nothing about how the Style system works now.

The headers of the concrete style implementations are "private" and not installed.

If you need a base class for an own style you can use QCommonStyle.
If you want to create a style at runtime, just use QApplication::setStyle(QString) or QStyleFactory::create(QString) and the style's name.

Cheers,
