c++ - 拆分窗口Qt

Question

我有 Qt C++ 相关的问题。我需要将窗口分成 4 个部分。其中 3 个应该是 QTableWidgets（示例图片上的红色、黄色和绿色区域），但它们必须成对同步（红色和黄色、红色和绿色 - 一个的线条延续另一个的线条）所以当你水平滚动红色 QTableWidget - 同时水平滚动绿色 QTableWidget（反之亦然），并且垂直滚动红色 QTableWidget - 同时垂直滚动黄色 QTableWidget（反之亦然）。此外，我需要有可能调整拖动边框的区域大小（图片上的灰色箭头）。因此，当我拖动每个边框时 - 它会更改 2 个相应 QTableWidgets 的大小。

我很高兴知道如何实现这一点。预先感谢！

重现您的图像的最小示例：

#include <QApplication>
#include <QTableWidget>
#include <QSplitter>
#include <QHBoxLayout>
#include <QScrollBar>
#include <QHeaderView>
#include <QTimer>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QSplitter *vSplitter2 = new QSplitter(Qt::Vertical,&mainW);
    QTableWidget *tableRed = new QTableWidget(6,6,&mainW);
    tableRed->verticalHeader()->setSectionResizeMode(QHeaderView::Stretch);

    tableRed->horizontalHeader()->hide();
