如何改变标签或者或者Widget的背景颜色啊 [复制链接]

想让一个标签背景色为其他颜色。好像没有可设置的属性，如果不行把标签拖到一个 widget上面，，再改变widget的颜色行不行啊，好像也没有可设置的地方，晕怎么搞呢？

palette : QPalette
This property holds the widget's palette.
As long as no special palette has been set, this is either a special palette for the widget class, the parent's palette or (if this widget is a top level widget), the default application palette.
Note: The palette's background color will only have an effect on the appearance of the widget if the autoFillBackground property is set.
Warning: Do not use this function in conjunction with Qt Style Sheets. When using style sheets, the palette of a widget can be customized using the "color", "background-color", "selection-color", "selection-background-color" and "alternate-background-color".
Access functions:
const QPalette & palette () const
void setPalette ( const QPalette & )
See also QApplication::palette().

使用palette或者使用styleSheet

将label背景色设为红色
label.setStyleSheet("background-color: rgb(255, 0, 0);");
