How do I "split the window"?

Anonymous_Banned275

This post is about same issue I have posted elsewhere, but it is NOT a dupe....

I just need some fresh , different idea how to solve

I have "main window " ( QMainWindow) where

setCentralWidget(m_console);

is my current, final "view" I/O "window" ( plain text class )

and it does the job accessing the serial port....

What I want is to have ANOTHER way to access the serial port - ideally showing BOTH the original console "view" and the new means to access same serial port.

I have replaced the "console" with MDIArea , however it is getting too convoluted to have the original "console" and the
new access as TWO subwindow of the MDIArea....

In not so technical description - how do I "split" the current I//O ( console ) "window" and add another "view" of same serial port.

So currently I have
(main) MDI class
real subwindow - QMainWindow ( access to serial ports)
console class as I/O

what I like to have

(main) MDI class
rear subwindow - QMainWindow ( access to serial ports)

intermediate way / class - split final view
original view - console class as I/O
new , additional view - serial control class as I/O

    m_settings(new SettingsDialog),

    m_serial(new QSerialPort(this))
//! [1]
{

    m_ui->setupUi(this);
    m_console->setEnabled(false);
    setCentralWidget(m_console);

***replaced with  QMainWindow -> QMDIArea*** 

    m_ui->actionConnect->setEnabled(true);
    m_ui->actionDisconnect->setEnabled(false);
    m_ui->actionQuit->setEnabled(true);
    m_ui->actionConfigure->setEnabled(true);

    m_ui->statusBar->addWidget(m_status);

    initActionsConnections();

    connect(m_serial, &QSerialPort::errorOccurred, this, &MainWindow_Serial::handleError);

    connect(m_serial, &QSerialPort::readyRead, this, &MainWindow_Serial::readData);
//! [2]
    connect(m_console, &Console::getData, this, &MainWindow_Serial::writeData);
//! [3]
}

Hi @AnneRanch,

Personally I like to use QDockWidget for this. So you can easily move, resize, hide/show your view according to your needs.

Something like that

QDockWidget *dock = new QDockWidget(tr("Serial"), this);
dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
m_serialCtrl = SerialControlWidget()
dock->setWidget(serialCtrl);
this->addDockWidget(Qt::RightDockWidgetArea, dock);
// Optional, allow to show/hide view from the menu and/or toolbar
viewMenu->addAction(dock->toggleViewAction());

Another possibility would be to use a QSplitter as main widget, and set your two widgets console and serial as "childs".

//setCentralWidget(m_console);
QSplitter *splitter = new QSplitter(Qt::Horizontal);
splitter.addWidget(m_console);
splitter.addWidget(m_serialCtr);
setCentralWidget(m_serialCtrl);
