我正在使用垂直布局(QVBoxLayout)来管理县。 我要说,其背景是50%的黑色透明。 是否可能?

如果你想要透明地区的边界,你需要把 but子混为一谈(SigTerm说过的话),然后,你可以通过棕榈树分配彩色。
QPalette palette = widget->palette();
palette.setColor(QPalette::Window, QColor(100,100,100,100));
widget->setPalette(palette);
或使用风格
widget->setStylesheet("QWidget{background-color: rgba(100,100,100,100);}";
风格上的好处是,你可以把你的所有申请从不列入守则的某一地点上划出,并通过<代码>QApplication:setStylesheet(QString)设定了广泛的应用风格。

如果你想制造有色的布局,你很可能不得不以你所希望的颜色来制造一种植被,然后是母体QVBoxLayout。
如果你想让所有非专业儿童受到QVBoxLayout父母的肤色的影响,那就会变得更令人沮丧,但我认为,从Qt4 demo来看,“受感染的糖尿病”可能给你一个想法,说明如何做。
