    <p>I see that <code>QMdiArea</code> has a tabbed view mode. I want to be able to split the main window with two <code>QMdiArea</code> widgets and to be able to drag and drop tabs between each of them. I have already done it with a simple <code>QTabWidget</code> where I can set custom tab bar. At the same time I want to switch <code>QMdiArea</code> view mode thus using <code>QTabWidget</code> is not an option for me. But I don't see any methods to set custom tab bar within <code>QMdiArea</code>. I still have hope that it could be done. Can anyone suggest something?</p> <h3>Tested solution for Qt 4.8 (edit)</h3> <p>After some time of research I can suggest the following solution. You have to make a new class inheriting <code>QMdiArea</code>. Set its view mode to <code>TabbedView</code> to make the standart <code>QTabBar</code> to be constructed within <code>QMdiArea</code>. Then get all children and find <code>QTabBar</code> widget with <code>QString(QObject::metaObject()-&gt;className()) == "QTabBar"</code>. Hide it. You will get a blank area above the document in <code>TabbedView</code> mode. Construct you custom tab bar and reparent it to your custom mdi area. Connect signals and slots that are fired and used when the sub windows and tabs are activated. You can have your custom tab bar as a class member of your custom mdi area.</p> <p>If you have found this post useful please vote on it. Thanks.</p> <p>Some code for example.</p> <ol> <li><p>Looking for a standart <code>QTabBar</code> within a custom mdi area in its constructor:</p> <pre><code>m_pMdiAreaTabBar = NULL; m_pMdiArea-&gt;setViewMode(QMdiArea::TabbedView); QObjectList listChildren = m_pMdiArea-&gt;children(); for (QObjectList::Iterator i = listChildren.begin(); i != listChildren.end(); ++i) { if (QString((*i)-&gt;metaObject()-&gt;className()) == "QTabBar") { m_pMdiAreaTabBar = dynamic_cast&lt;QTabBar*&gt;(*i); break; } } </code></pre></li> <li><p>Reparent:</p> <pre><code>m_pTabBar-&gt;setParent(m_pMdiArea); </code></pre></li> <li><p>Hiding:</p> <pre><code>if (m_pMdiAreaTabBar != 0) m_pMdiAreaTabBar-&gt;hide(); </code></pre></li> <li><p>Signals &amp; Slots used: <code>QMdiArea::subWindowActivated(QMdiSubWindow*)</code>, <code>QTabBar::currentChanged(int)</code></p></li> </ol>

    1. COI think I have a solution. I have found there http://qt-project.org/forums/viewthread/13140 that it is possible to get tab bar through QMdiArea.findChild(QtGui.QTabBar). So I can simply hide it. Then I can use a mix of QMdiArea and a custom tab bar layed out in a simple widget. I can also provide interface to both QMdiArea and tab bar. I think that will do the job. I have to check out. Have to post on qt-project this workaround.

    3. COBeware, `QMdiArea`'s `QTabBar` child widget is constructed at request, for example when you set `QMdiArea`'s view mode to `TabView`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
