如果我正确理解你的话,你就想把不仅改变其立场,而且改变其像你们幻灯一样的表面吗? 例如,QDial和QSlider的混合体。 a 折合点。
如果是的话,你将需要将QSlider或QAbstractSlider(或QDial)分类,并在你自己的油漆中做油漆。 不过,请注意,除非你关注这一分析,否则你会放松所有风格的认知(这本身是一个有趣的议题,见rel=“nofollow”http://doc.qt.io/qt-4.8/e-参比.html>。
Qt demos和范例,或QSlider/QDial source代码本身,可作为如何超载油漆喷口的实例。
您可以使用QProxyStyle来规避ComplexControl方法,因为QStyle没有单独的国旗:Control QSlider的部件。
