PyQt5 QColorDialog – 为子按钮设置皮肤

在这篇文章中，我们将看到如何为QColorDialog的按钮即它的子按钮设置皮肤。QColorDialog是PyQt5中用于选择和创建颜色的弹出式窗口部件。颜色对话框是一个巨大的部件，由许多子部件组成，所以为颜色对话框设置样式表变得很困难，因为它是一个复杂的部件。皮肤基本上是背景图片，它可以根据小组件的大小自我调整，下面是QColorDialog小组件的按钮皮肤的样子

为了做到这一点，我们必须在setStyleSheet方法的帮助下为QColorDialog对象设置样式表，下面是样式表的代码

QColorDialog QPushButton
{
border-image : url(image.png);
}

以下是实施情况
