PyQt5怎么设置QComboBox的背景、字体颜色

背景颜色

参考文档：https://www.cnblogs.com/aheng123/p/5630761.html

ComboBox = self.my_tableWidget_3.cellWidget(0, 0)
        if ComboBox.currentText() == "一级文件":
            self.tab_3_first_level()
            ComboBox.setStyleSheet("QComboBox{background:yellow}")
        elif ComboBox.currentText() == "二级文件":
            self.tab_3_second_level()

• 关键点

ComboBox.setStyleSheet("QComboBox{background:yellow}")

字体颜色

ComboBox.setStyleSheet("QComboBox{color:rgb(30,144,255)}")
