Question

怎么把做好的窗口放到另一个主窗口的stackedWidget里

Answer 1

stackedwidget->addwidget(widget1);
stackedwidget->addwidget(widget2);
stackedwidget->addwidget(widget3);
connect(listwidget,signal(currentrowchanged(int)),this,slot(widgetchanged(int)));

在widgetchanged槽函数里实现代码
{
stackedwidget->setcurrentindex(index);
}
