Qt About using layouts, widget parenting Combining Layouts
Example
You can combine mulple layout thanks to other QWidgets in your main layout to do more specifics effects like an information field: for example:
#include <QApplication>
#include <QMainWindow>
#include <QWidget>
#include <QVBoxLayout>
#include <QPushButton>
#include <QLabel>
#include <QLineEdit>
#include <QGroupBox>
#include <QTextEdit>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QMainWindow window;
QWidget *widget = new QWidget(&window);
QVBoxLayout *layout = new QVBoxLayout(widget);
window.setCentralWidget(widget);
widget->setLayout(layout);
QGroupBox *box = new QGroupBox("Information:", widget);
QVBoxLayout *boxLayout = new QVBoxLayout(box);
layout->addWidget(box);
QWidget* nameWidget = new QWidget(box);
QWidget* ageWidget = new QWidget(box);
QWidget* addressWidget = new QWidget(box);
boxLayout->addWidget(nameWidget);
boxLayout->addWidget(ageWidget);
boxLayout->addWidget(addressWidget);
QHBoxLayout *nameLayout = new QHBoxLayout(nameWidget);
nameLayout->addWidget(new QLabel("Name:"));
nameLayout->addWidget(new QLineEdit(nameWidget));
QHBoxLayout *ageLayout = new QHBoxLayout(ageWidget);
ageLayout->addWidget(new QLabel("Age:"));
ageLayout->addWidget(new QLineEdit(ageWidget));
QHBoxLayout *addressLayout = new QHBoxLayout(addressWidget);
addressLayout->addWidget(new QLabel("Address:"));
addressLayout->addWidget(new QLineEdit(addressWidget));
QWidget* validateWidget = new QWidget(widget);
QHBoxLayout *validateLayout = new QHBoxLayout(validateWidget);
validateLayout->addWidget(new QPushButton("Validate", validateWidget));
validateLayout->addWidget(new QPushButton("Reset", validateWidget));
validateLayout->addWidget(new QPushButton("Cancel", validateWidget));
layout->addWidget(validateWidget);
window.show();
return a.exec();
}
will output :
