QDockWidget上的多个小部件

Question

我正在制作一个小应用程序,使用Qt和C++在图像上应用各种过滤器.

我的问题是,是否可以在QDockWidget上添加多个小部件？因为我想添加按钮以重新应用Dock上的最后5个过滤器.

这是我想要实现的一个例子.

It is possible add to multiple QWidgets into any QWidget. It looks like you probably want to do something like this:

QDockWidget dock(QLatin1String("Last filters"));
QWidget* multiWidget = new QWidget();
QVBoxLayout* layout = new QVBoxLayout();
QPushButton* filter1 = new QPushButton(QLatin1String("Filter number 1"));
QPushButton* filter2 = new QPushButton(QLatin1String("Filter number 2"));
QPushButton* filter3 = new QPushButton(QLatin1String("Filter number 3"));
QPushButton* filter4 = new QPushButton(QLatin1String("Filter number 4"));
QPushButton* filter5 = new QPushButton(QLatin1String("Filter number 5"));
QLabel* label = new QLabel(QLatin1String("QPushButtons"));

layout->addWidget(filter1);
layout->addWidget(filter2);
layout->addWidget(filter3);
layout->addWidget(filter4);
layout->addWidget(filter5);
layout->addWidget(label);
multiWidget->setLayout(layout);
dock.setWidget(multiWidget);
