QMainWindow :: splitDockWidget的QDockWidget伸展因子？

Question

我正在使用QMainWindow在C++中手动布局Qt应用程序.我想在屏幕底部放置两个并排停靠的小部件,但我希望它们具有不成比例的宽度.目前,我只能让它们具有相同的宽度.有没有办法设置拉伸因子或其他机制来获得不均匀的码头拆分？

这是我目前如何铺设它们:

OutputPanel* outputPanel = new OutputPanel;
mainWindow.addDockWidget(Qt::BottomDockWidgetArea, outputPanel);

ThumbnailViewer* thumbnailViewer = new ThumbnailViewer;
mainWindow.splitDockWidget(outputPanel, thumbnailViewer, Qt::Horizontal);

这是我想要实现的目标的图像:

谢谢!

正如你的建议使用QMainWindow :: resizeDocks.设置resizeDock参数后,在主窗口调整大小时保持相对比例.

#include "mainwindow.h"

#include <QApplication>
#include <QLabel>
#include <QDockWidget>
#include <QList>

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

    MainWindow w;
    w.setCentralWidget(new QLabel("MAIN WINDOW CONTENTS"));

    QDockWidget* dwa = new QDockWidget("DOCK A");
    dwa->setWidget(new QLabel("DOCK A CONTENTS"));

    QDockWidget* dwb = new QDockWidget("DOCK B");
    dwb->setWidget(new QLabel("DOCK B CONTENTS"));

    w.addDockWidget(Qt::BottomDockWidgetArea, dwa);
    w.addDockWidget(Qt::BottomDockWidgetArea, dwb);

    w.splitDockWidget(dwa, dwb, Qt::Horizontal);

    w.show();

    QList<QDockWidget*> docks = { dwa, dwb };

    float windowWidth = w.size().width();
    int dockWidthA = 0.60 * windowWidth;
    int dockWidthB = 0.40 * windowWidth;

    QList<int> dockSizes = { dockWidthA, dockWidthB };

    w.resizeDocks(docks, dockSizes, Qt::Horizontal);

    return a.exec();
}
