Examples of setting up a QScrollArea



  • Ugh. Scrollbars.

    I have a need where I have a splitter with two panels. On the left panel, I need to insert a QScrollArea. Inside the QScrollArea, I have custom QWidget that draws a custom hierarchy tree.

    So far, I have things sorta working with this setup code:

    @ m_hierWindow = new HierWidget(this);
    m_hierWindow->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);

    // SETUP MAIN WINDOW
    m_scroller = new QScrollArea(this);
    m_scroller->setBackgroundRole(QPalette::Dark);
    ui->TreeView->addWidget(m_scroller);
    ui->ModelView->addWidget(m_model);

    m_scroller->setWidget(m_hierWindow);
    @

    Can someone point me to a good tutorial of how to setup the QScrollArea inside a splitterwindow? I see this done all the time in Qt Creator. It can't be that difficult.

    Thanks in Advance

    Hi,

    The code you posted is a bit confusing.

    @
    ui->TreeView->addWidget(m_scroller); <- TreeView is a layout ?
    ui->ModelView->addWidget(m_model); <- ModelView is a layout ? m_model a widget ?
    @

    In short for using a QScrollArea in a QSplitter:

    @
    QSplitter *splitter = new QSlitter;
    QScrollArea *scrollArea = new QScrollArea;
    splitter->addWidget(scrollArea);

    // Modify scrollArea as you see fit
    @

    Hope it helps
