我是靠谱客的博主贤惠冬日，最近开发中收集的这篇文章主要介绍QPalette设置各种背景色，觉得挺不错的，现在分享给大家，希望可以做个参考。

设置空间背景色

setAutoFillBackground(true); //设置自动填充

    QPalette palette = this->palette();

    palette.setColor(QPalette::Background,Qt::black);

    setPalette(palette);

注：QPalette::ColorRole

`QPalette::Window`	`10`	通常指窗口部件的背景色
`QPalette::Background`	`Window`	This value is obsolete. Use Window instead.
`QPalette::WindowText`	`0`	通常指窗口不见的前景色;
`QPalette::Foreground`	`WindowText`	This value is obsolete. Use WindowText instead.
`QPalette::Base`	`9`	指文本输入窗口部件(比如QtextEdit,QLinedit等)的背景色.
`QPalette::AlternateBase`	`16`	Used as the alternate background color in views with alternating row colors (seeQAbstractItemView::setAlternatingRowColors()).
`QPalette::ToolTipBase`	`18`	提示符背景色
`QPalette::ToolTipText`	`19`	提示符前景色
`QPalette::Text`	`6`	与QPalette::Base一块使用,指文本输入窗口部件的前景色;
`QPalette::Button`	`1`	指按钮窗口部件的背景色;
`QPalette::ButtonText`	`8`	指按钮窗口部件的前景色.
`QPalette::BrightText`	`7`	A text color that is very different from `WindowText`, and contrasts well with e.g. `Dark`. Typically used for text that needs to be drawn where `Text` or `WindowText` would give poor contrast, such as on pressed push buttons. Note that text colors can be used for things other than just words; text colors are usually used for text, but it's quite common to use the text color roles for lines, icons, etc.
