qt - 如何在可折叠面板中实现大小相等的 FormLayout？

Question

我认为这可能是两个独立的问题。在Qt4.8中，QFormLayout是

The QFormLayout class manages forms of input widgets and their associated labels.

QFormLayout is a convenience layout class that lays out its children in a two-column form. The left column consists of labels and the right column consists of "field" widgets (line editors, spin boxes, etc.).

以下图为指导，

1)如何创建两个可折叠的可折叠面板？就像两个蓝色矩形一样？我已经尝试过QGroupBox，但其中没有任何可折叠属性。

2)如何使两个独立的QFormLayout具有相同的标签和字段比例，即使它们属于不同的可折叠面板？如附图所示，我们可以看出这两个表单布局已对齐，如绿线所示。

我希望您有可折叠的代码，并且只需要 QFormLayout 的代码。我相信这应该可以解决问题。

头文件:

#pragma once

#include <QtGui>
#include <QtCore>

class newQtApp : public QMainWindow {
    Q_OBJECT

    public :
        newQtApp();
};

newQtApp::newQtApp() : QMainWindow() {

    cout << "Im being initialized...." << endl;
    cout << "Setting window properties..." << endl;

    QFormLayout *fLyt1 = new QFormLayout();
    fLyt1->setLabelAlignment( Qt::AlignRight );
    for( int i = 0; i < 5; i++ ) {
        QLabel *lbl = new QLabel( QString( "Lyt 1, Label %1:" ).arg( i + 1), this );
        lbl->setFixedWidth( 150 );
        lbl->setAlignment( Qt::AlignRight );

        fLyt1->addRow( lbl, new QLineEdit() );
    }

    QGroupBox *w1 = new QGroupBox( "First Collapsible", this );
    w1->setLayout( fLyt1 );

    QFormLayout *fLyt2 = new QFormLayout();
    fLyt2->setLabelAlignment( Qt::AlignRight );
    for( int i = 0; i < 5; i++ ) {
        QLabel *lbl = new QLabel( QString( "Second Layout, Label %1:" ).arg( i + 1), this );
        lbl->setFixedWidth( 150 );
        lbl->setAlignment( Qt::AlignRight );

        fLyt2->addRow( lbl, new QCheckBox( "Check this out!!" ) );
    }

    QGroupBox *w2 = new QGroupBox( "Second Collapsible", this );
    w2->setLayout( fLyt2 );

    QVBoxLayout *baseLyt = new QVBoxLayout();
    baseLyt->addWidget( w1 );
    baseLyt->addWidget( w2 );

    QWidget *base = new QWidget( this );
    base->setLayout( baseLyt );

    setCentralWidget( base );
};
