如何向父QWidget添加滚动条

发布于 2024-09-12 22:43:27 字数 601 浏览 5 评论 0原文

我了解如何将滚动区域添加到特定的小部件。然而，就我而言，Qwidget 有多个子小部件，这些小部件都是使用 QVBoxLayout 设置的。现在在这种情况下如何添加滚动条？这里 QWidget 不是中心小部件，它是 TabWidget 的页面之一。我的代码如下所示：

QTabWIdget *center = new QTabWidget; setCentralWIdget(center);

xTab = new QWidget;

formLayout = new QFormLayout; formLayout->addWidget(...); formLayout->addWidget(...); formLayout->addWidget(...); formLayout->addWidget(...);

xTab->setLayout(formLayout);

现在如何将滚动条设置为 xTab？我尝试使用

scrollArea = new QScrollArea;
scrollArea->setWidget(xTab);

但是，这不起作用。

任何想法/建议都是有帮助和赞赏的。

I understand how to add a scrollArea to a particular widget. However in my case Qwidget has multiple child widgets and these are all set using QVBoxLayout. Now how can I add a scroll bar in this case? Here QWidget is not the center widget, its one of the pages of the TabWidget. My code looks like:

QTabWIdget *center = new QTabWidget; setCentralWIdget(center);

xTab = new QWidget;

formLayout = new QFormLayout; formLayout->addWidget(...); formLayout->addWidget(...); formLayout->addWidget(...); formLayout->addWidget(...);

xTab->setLayout(formLayout);

Now how can I set the scrollBar to xTab? I tried using

scrollArea = new QScrollArea;
scrollArea->setWidget(xTab);

however, this isn't working.

Any idea/suggestions are helpful and appreciated.

您是否尝试过使用QScrollArea作为标签页？

QTabWIdget *center = new QTabWidget; setCentralWIdget(center);

xTab = new QScrollArea; 
formLayout = new QFormLayout; formLay....
xTab->setLayout(formLayout);
center->addTab(xTab, "XXX Tab");

Have you tried using QScrollArea as the tab page?

QTabWIdget *center = new QTabWidget; setCentralWIdget(center);

xTab = new QScrollArea; 
formLayout = new QFormLayout; formLay....
xTab->setLayout(formLayout);
center->addTab(xTab, "XXX Tab");

我使用以下方法取得了成功：

scroll=new QScrollArea(mainWindow->centralWidget);
scroll->setGeometry(mainWindow->tabWidget->geometry());
scroll->setWidget(mainWindow->tabWidget);
scroll->show();

QScrollArea 定义了可滚动小部件将出现的位置。如果parent为0，则它是一个非模态窗口。 setGeometry 将 QScrollArea 实例设置为所需的尺寸（选项卡的尺寸）。 setWidget 定义 QScrollArea 将实际滚动的小部件。

I had success using the following:

scroll=new QScrollArea(mainWindow->centralWidget);
scroll->setGeometry(mainWindow->tabWidget->geometry());
scroll->setWidget(mainWindow->tabWidget);
scroll->show();

The QScrollArea defines where the scrollable widget will appear. If parent is 0, it's a non-modal window. setGeometry sets the QScrollArea instance to the desired dimensions (that of the tab). setWidget defines what widget the QScrollArea will actually be scrolling.
