[提问]Qt QSplitter 分隔线再次打开是上一次保存的 [复制链接]

网上看到的都是下面，但是具体怎么用，还是不会，请教会的人！

void FileBrowser::WriteSetting()
{
    QSettings settings("fileBrowser Inc.","MainClient");
    settings.beginGroup("mainWindow");
    resize(settings.value("size",QSize(480,360)).toSize());
    settings.setValue("mainSplitter",qSplitter->saveState());
    settings.endGroup();
}

void FileBrowser::ReadSetting()
{
    QSettings settings("fileBrowser Inc.","MainClient");
    settings.beginGroup("mainWindow");
    settings.setValue("size",QSize(480, 360));
    qSplitter->restoreState(settings.value("mainSplitter").toByteArray());
    settings.endGroup();
}

求排版……
