@cerr
can you show me what u get using image ?

@cerr The default alignment is already Qt::AlignLeft.

@cerr Looks like you have added the groupbox in a layout?
Can you post the relevant code ?

Correct,

Okay, so let's see:
My groupBox is here, in addTerminal() which gets called with a QSplitter as parent... - not sure if that's enough...

Terminal* Session::addTerminal(QWidget* parent)
{
    Terminal* terminal = new Terminal(parent);
    connect(terminal, SIGNAL(activated(int)), this, SLOT(setActiveTerminal(int)));
    connect(terminal, SIGNAL(manuallyActivated(Terminal*)), this, SIGNAL(terminalManuallyActivated(Terminal*)));
    connect(terminal, SIGNAL(titleChanged(int,QString)), this, SLOT(setTitle(int,QString)));
    connect(terminal, SIGNAL(keyboardInputBlocked(Terminal*)), this, SIGNAL(keyboardInputBlocked(Terminal*)));
    connect(terminal, SIGNAL(silenceDetected(Terminal*)), this, SIGNAL(silenceDetected(Terminal*)));
    connect(terminal, SIGNAL(destroyed(int)), this, SLOT(cleanup(int)));

    m_terminals.insert(terminal->id(), terminal);    
    
    QGroupBox *groupBox = new QGroupBox(tr("Test"), parent);
    groupBox->setAlignment(Qt::AlignLeft);
    QWidget* terminalWidget = terminal->terminalWidget();
    QVBoxLayout *vbox = new QVBoxLayout;
    vbox->addWidget(terminalWidget);
    groupBox->setLayout(vbox);
    terminalWidget ->show();
    if (/*terminalWidget*/groupBox) /*terminalWidget*/groupBox->setFocus();
    groupBox->show();

    return terminal;
}

and then, the constructor for Terminal() looks like this:

Terminal::Terminal(QWidget* parent) : QObject(parent)
{
    m_terminalId = m_availableTerminalId;
    m_availableTerminalId++;

    m_keyboardInputEnabled = true;

    m_monitorActivityEnabled = false;
    m_monitorSilenceEnabled = false;

    m_part = NULL;
    m_terminalInterface = NULL;
    m_partWidget = NULL;
    m_terminalWidget = NULL;
    m_parentSplitter = parent;

    KPluginFactory* factory = 0;
    KService::Ptr service = KService::serviceByDesktopName("konsolepart");
    if( service )
    {
        factory = KPluginLoader(service->library()).factory();

    m_part = factory ? (factory->create<KParts::Part>(parent)) : 0;

    if (m_part)
    {
        connect(m_part, SIGNAL(setWindowCaption(QString)), this, SLOT(setTitle(QString)));
        connect(m_part, SIGNAL(overrideShortcut(QKeyEvent*,bool&)), this, SLOT(overrideShortcut(QKeyEvent*,bool&)));
        connect(m_part, SIGNAL(destroyed()), this, SLOT(deleteLater()));

        m_partWidget = m_part->widget();

        m_terminalWidget = m_part->widget()->focusWidget();

        if (m_terminalWidget)
        {
            m_terminalWidget->setFocusPolicy(Qt::WheelFocus);
            m_terminalWidget->installEventFilter(this);
        }

        disableOffendingPartActions();

        m_terminalInterface = qobject_cast<TerminalInterface*>(m_part);
        if (m_terminalInterface) m_terminalInterface->showShellInDir(QDir::homePath());
    }
    else
        displayKPartLoadError();
    }
}

@cerr This part looks odd:

QVBoxLayout *vbox = new QVBoxLayout;
vbox->addWidget(terminalWidget);
groupBox->setLayout(vbox);

You should set layout (vbox) to your main widget and in this layout add widgets groupBox and terminalWidget.

Hmm, I don't get this, so are you saying this should look something like:

    QVBoxLayout *vbox = new QVBoxLayout;
    vbox->addWidget(terminalWidget);
    vbox->addWidget(groupBox);
    parent->setTerminalLayout(vbox); // vbox->setLayout() would be called within this method
    terminalWidget ->show();
    if (groupBox) groupBox->setFocus();

but I don't see what a differnce it'll make to call setLayout from within another wrapper , I must not understand you properly - can you clarify, please?

Thanks!

@cerr What I imagined was that you are trying to create a main widget and in that you want to add a groupbox and terminalwidget so I suggested to add this layout(vbox) to the main widget and in that you add these 2 widgets so that they are arranged vertically. Is this the requirement ?

By main widget you understand a "mother widget" that would contain the groupbox & the terminal widget, right? What I want to do is, to nest the terminalwidget within a groupbox so that there is an ability to assign the terminalwidget some kind of membership (that makes visually sense, too). If you have a better idea on how to solve this, please don't be shy to let me know! Thanks!

@cerr

Yes.

So now where do you add this groupbox ? You should add this groupbox inside another layout so that it is laid properly.

So I currently have something lke groupBox(vbox(terminalWidget())) and I think from what you're saying, I should have something like ContainerWidget(vbox(groupBox(terminalWidget))), is that correct? Any idea what kind of container widget I can use for this? Or better, vbox(groupBox(terminalWidget)) should do as well, shouldn't it?

[p3c0]

@cerr

ContainerWidget(vbox(groupBox(terminalWidget))), is that correct?

Yes. You can use QDialog as the container widget.

Yes. You can use QDialog as the container widget.

But I don't want it to be in abother dialog and it already is in a QTabWidget....I should use that as the outer most layer probably...

[p3c0]

@cerr Ok. But remember to add that groupbox inside a layout.

@cerr Ok. But remember to add that groupbox inside a layout.

So what actually happens in my application is:
MainWindow->QTabWidget->session->setupSession->addTerminal->QVBoxWidget(QGroupBox->terminalWidget) and you suggest i'd better be like mainwindow->QVBoxWidget(QTabWidget->session->setupSession->addTerminal->QGroupBox->terminalWidget) ?
Will that change things?

[p3c0]

@cerr No. The earlier one.
MainWindow->QTabWidget->session->setupSession->addTerminal->QVBoxWidget(QGroupBox->terminalWidget)

But I dont see that happening in your original code.

QGroupBox *groupBox = new QGroupBox(tr("Test"), parent); //<--- This should be added in a layout too.
groupBox->setAlignment(Qt::AlignLeft);

QWidget* terminalWidget = terminal->terminalWidget();

QVBoxLayout *vbox = new QVBoxLayout;
vbox->addWidget(terminalWidget);
groupBox->setLayout(vbox); // <--- This sets layout inside it

terminalWidget ->show();
if (/*terminalWidget*/groupBox) /*terminalWidget*/groupBox->setFocus();
   groupBox->show();

groupBox->setLayout(vbox); // <--- This sets layout inside it

terminalWidget ->show();
if (/*terminalWidget*/groupBox) /*terminalWidget*/groupBox->setFocus();
   groupBox->show();

Sorry,

Yeah, I had changed it in the meantime to:

    QGroupBox *groupBox = new QGroupBox(tr("Test"), parent);
    groupBox->setAlignment(Qt::AlignLeft);
    QWidget* terminalWidget = terminal->terminalWidget();
    QVBoxLayout *vbox = new QVBoxLayout;
    vbox->addWidget(terminalWidget);
    vbox->addWidget(groupBox);
    //groupBox->setLayout(vbox);  <- if i remove the comment, it won't start my application at all...
    terminalWidget ->show();
    if (/*terminalWidget*/groupBox) /*terminalWidget*/groupBox->setFocus();

[p3c0]

@cerr So now set vbox as a layout to its parent widget.

Did you mean like?

QVBoxLayout *vbox = new QVBoxLayout;
    vbox->addWidget(terminalWidget);
    vbox->addWidget(groupBox);
    vbox->addWidget(parent);
    groupBox->setLayout(vbox);
    terminalWidget ->show();
``` - that doesn't let me open my application...

[p3c0]

@cerr Probably something like this. Assuming QDialog is my main widget which contains groupbox.

QVBoxLayout *mainLayout = new QVBoxLayout;
myDialog->setLayout(mainLayout);

//Now add widgets into this layout

mainLayout->addWidget(groupBox);// groupbox first
mainLayout->addWidget(terminalWidget);

Now in your case if you want to add terminalWidget inside a groupbox's layout you can create new one and add into it keeping mainLayout as it is.
