Body
I have a simple code in Qt, as below: <pre><code>#include "mainwindow.h" #include <QWidget> #include <QGroupBox> #include <QLabel> #include <QLineEdit> #include <QGridLayout> #include <QVBoxLayout> class classA; class classB; MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { classA * objA = new classA(this); classB * objB = new classB(this); QVBoxLayout * mainLayout = new QVBoxLayout(this); setLayout(mainLayout); mainLayout->addWidget(objA); mainLayout->addWidget(objB); } MainWindow::~MainWindow(){} classA::classA(QWidget *parent) : QWidget(parent) { QGroupBox *grupa = new QGroupBox(tr("classA"),this); QLabel *labelA1 = new QLabel(tr("Label A1")); QLabel *labelA2 = new QLabel(tr("Label A2")); QLineEdit *LineEditA1 = new QLineEdit("LineEditA1"); QLineEdit *LineEditA2 = new QLineEdit("LineEditA2"); QGridLayout *lay = new QGridLayout(grupa); lay->addWidget(labelA1, 0, 0, Qt::AlignLeft); lay->addWidget(LineEditA1, 0, 1, Qt::AlignLeft); lay->addWidget(labelA2, 1, 0, Qt::AlignLeft); lay->addWidget(LineEditA2, 1, 1, Qt::AlignLeft); grupa->setLayout(lay); } classA::~classA(){} classB::classB(QWidget *parent) : QWidget(parent) { QGroupBox *grupa = new QGroupBox(tr("classB"),this); QLabel *labelB1 = new QLabel(tr("Label B1")); QLabel *labelB2 = new QLabel(tr("Label B2")); QLineEdit *LineEditB1 = new QLineEdit("LineEditB1"); QLineEdit *LineEditB2 = new QLineEdit("LineEditB2"); QGridLayout *lay = new QGridLayout(grupa); lay->addWidget(labelB1, 0, 0, Qt::AlignLeft); lay->addWidget(LineEditB1, 0, 1, Qt::AlignLeft); lay->addWidget(labelB2, 1, 0, Qt::AlignLeft); lay->addWidget(LineEditB2, 1, 1, Qt::AlignLeft); grupa->setLayout(lay); } classB::~classB(){} </code></pre> As a result, I should see a window with a nicely spaced elements. Unfortunately, I have something like this: <img src="https://i.stack.imgur.com/uqf3K.jpg" alt="alt text"> What am I doing wrong that these items will not spaced properly?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
