QMdiArea

How can QtitanRibbon work together with QMidArea?
My code like this , but the hold can't fill client window.
holder = new RibbonWorkspace(this);
    holder->setAttribute(Qt::WA_CanHostQMdiSubWindowTitleBar);

    m_mdiArea = new QMdiArea(holder);

    m_mdiArea->setLineWidth(3);
    m_mdiArea->setFrameShape(QFrame::Panel);
    m_mdiArea->setFrameShadow(QFrame::Sunken);
    m_mdiArea->setViewMode(QMdiArea::TabbedView);
    setCentralWidget(holder);
    m_mdiArea->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);
    m_mdiArea->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);

    m_mdiArea->addSubWindow(new QTableWidget());
    m_mdiArea->addSubWindow(new QTableWidget());
    m_mdiArea->addSubWindow(new QTableWidget());

Hello!
You can’t fill full client window with this code. RibbonWorkspace is a common widget not having an inner layout, so it doesn’t control its children geometry. Class RibbonWorkspace was created to support qtitan styles, i.e. to fill background with the appropriate style. You can see the way we use it in our demo examples. In order to get desired result, there’s need to modify your code as in example below:
RibbonWorkspace* holder = new RibbonWorkspace(this);
holder->setAttribute(Qt::WA_CanHostQMdiSubWindowTitleBar);
QLayout* layout = new QHBoxLayout(holder);
layout->setSpacing(0);
layout->setMargin(0);
QMdiArea* m_mdiArea = new QMdiArea(holder);
layout->addWidget(m_mdiArea);

m_mdiArea->setLineWidth(3);
m_mdiArea->setFrameShape(QFrame::Panel);
m_mdiArea->setFrameShadow(QFrame::Sunken);
m_mdiArea->setViewMode(QMdiArea::TabbedView);
setCentralWidget(holder);
m_mdiArea->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);
m_mdiArea->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);

m_mdiArea->addSubWindow(new QTableWidget());
m_mdiArea->addSubWindow(new QTableWidget());
m_mdiArea->addSubWindow(new QTableWidget());

or to reload class RibbonWorkspace->MyRibbonWorkspace and use virtual function MyRibbonWorkspace::resizeEven. You can set QMdiArea sizes in it on your own.

P.S. If we properly understood why you used RibbonWorkspace, then please pay attention to our example Ribbon_MDIApplication where we fill out background in QMdiArea. May be you’ll need that
