推荐答案
阅读 Qt属性系统,这就像一个通常的类方法,但它可以与Qt的元对象系统一起使用:
Read about the Qt Property System , this is just like a usual class method but it can be used with Qt's meta-object system:
QPushButton *button = new QPushButton;
QObject *object = button;
button->setDown(true);
object->setProperty("down", true);
这些属性也将在Qt Designer下可见,因此您可以创建一个自定义窗口部件,请在Qt Designer中进行关联,请参阅本文详情。
Also these properties will be visible under Qt Designer too so you could create a custom widget with some properties and hook it up in Qt Designer, see this article for details.
