deepin fn快键失效

credentialWidget->setFixedSize(816, 53);

另外，你可以在循环结束后再加入QSpacerItem，这样可以确保弹簧位于所有密码条目的下方。修改后的代码如下：

QWidget *allCredentialsWidget=new QWidget(scrollArea);
QVBoxLayout *allCredentialsLayout=new QVBoxLayout(allCredentialsWidget);//设置样式
scrollArea->setWidget(allCredentialsWidget);//设置滚动
for(int i=0;i<x;i++){
QWidget credentialWidget=new QWidget(allCredentialsWidget);
credentialWidget->setFixedSize(816, 53);
allCredentialsLayout->addWidget(credentialWidget);
}
//设置密码条目底部弹簧
QSpacerItem passbookSpacer = new QSpacerItem(0, 0, QSizePolicy::Minimum, QSizePolicy::Expanding);
//将弹簧加入布局
allCredentialsLayout->addItem(passbookSpacer);
allCredentialsWidget->setLayout(allCredentialsLayout);

qt列表显示多个条目

```c++
//代码片段
    QScrollArea *scrollArea = new QScrollArea(passWidget);
    scrollArea->setFixedSize(836, 266);
    scrollArea->move(0,32);
    scrollArea->setWidgetResizable(true);
    QWidget *allCredentialsWidget=new QWidget(scrollArea);
    allCredentialsWidget->setFixedSize(816, 0);
    scrollArea->setWidget(allCredentialsWidget);
```

解决方案：QScrollArea边框设为0
`scrollArea->setFrameShape(QFrame::NoFrame);`

qt设置QScrollArea后出现白边

```c++
#include <DApplication>
#include <DMainWindow>
#include <DWidgetUtil>
#include <DApplicationSettings>
#include <DTitlebar>
#include <DProgressBar>
#include <DFontSizeManager>

#include <QPropertyAnimation>
#include <QDate>
#include <QLayout>
#include <QMenu>

#include "mainwindow.h"
DWIDGET_USE_NAMESPACE

int main(int argc, char *argv[])
{
  



    MainWindow w;
    w.show();
    // 创建系统托盘图标
    QSystemTrayIcon trayIcon;
    trayIcon.setIcon(QIcon(":/res/sakura.png")); // 设置图标
    trayIcon.setToolTip("樱花助手"); // 设置提示信息

    // 创建菜单
    QMenu *menu = new QMenu();
    QAction *quitAction = new QAction("退出", menu);
    menu->addAction(quitAction);

    // 将菜单添加到系统托盘图标中
    trayIcon.setContextMenu(menu);

    // 单击托盘图标时显示主程序
    QObject::connect(&trayIcon, &QSystemTrayIcon::activated, [&](QSystemTrayIcon::ActivationReason reason) {
        if (reason == QSystemTrayIcon::Trigger) {
            w.show();
        }
    });
    // 单击退出动作时退出应用程序
    QObject::connect(quitAction, &QAction::triggered, &w, &QApplication::quit);

    // 显示系统托盘图标
    trayIcon.show();


    return a.exec();
}

```
