QMainWindow (ForceTabbedDocks)

**baray98** · 14th August 2007, 18:54

I have 4 dockWidgets in my app and I want them to be "forced tabbed Docks" when they are docked in the main window to begin with . I did not declare any mainWidget in my main window ( i am not sure if it is ok ), I want my user to have the option to move the dock windows around but once the user dock it it should be a tabbed Docks mode.

code below at constructor ( this class inherits QMainwindow)

Qt Code:

Switch view

setDockOptions(QMainWindow::AnimatedDocks|
                   QMainWindow::AllowTabbedDocks|
                   QMainWindow::ForceTabbedDocks);
   //DockWidget No 1.
    QDockWidget *dock = new QDockWidget(QObject::tr("Sensor 1 - 12"), this);
    dock->setAllowedAreas( Qt::RightDockWidgetArea);
    ptrTrendPlotter1 = new TrendPlotter(dock,TrendPlotter::sensor1to12);
 
    dock->setWidget(ptrTrendPlotter1);
    addDockWidget(Qt::RightDockWidgetArea, dock);
 
    //DockWidget No 2.
    dock = new QDockWidget(QObject::tr("Sensor 13 - 24"), this);
    dock->setAllowedAreas( Qt::RightDockWidgetArea);
    ptrTrendPlotter2 = new TrendPlotter(dock,TrendPlotter::sensor13to24);
 
    dock->setWidget(ptrTrendPlotter2);
    addDockWidget(Qt::RightDockWidgetArea, dock);
 
     //DockWidget No 3.
    dock = new QDockWidget(QObject::tr("Sensor 25 - 36"), this);
    dock->setAllowedAreas( Qt::RightDockWidgetArea);
    ptrTrendPlotter3 = new TrendPlotter(dock,TrendPlotter::sensor25to36);
 
    dock->setWidget(ptrTrendPlotter3);
    addDockWidget(Qt::RightDockWidgetArea, dock);
 
    //DockWidget No 4
    dock = new QDockWidget(QObject::tr("Sensor 37 - 48"), this);
    dock->setAllowedAreas(Qt::RightDockWidgetArea);
    ptrTrendPlotter4 = new TrendPlotter(dock,TrendPlotter::sensor37to48);
 
    dock->setWidget(ptrTrendPlotter4);
    addDockWidget(Qt::RightDockWidgetArea, dock);

setDockOptions(QMainWindow::AnimatedDocks|
                   QMainWindow::AllowTabbedDocks|
                   QMainWindow::ForceTabbedDocks);
   //DockWidget No 1.
    QDockWidget *dock = new QDockWidget(QObject::tr("Sensor 1 - 12"), this);
    dock->setAllowedAreas( Qt::RightDockWidgetArea);
    ptrTrendPlotter1 = new TrendPlotter(dock,TrendPlotter::sensor1to12);

    dock->setWidget(ptrTrendPlotter1);
    addDockWidget(Qt::RightDockWidgetArea, dock);
    
    //DockWidget No 2.
    dock = new QDockWidget(QObject::tr("Sensor 13 - 24"), this);
    dock->setAllowedAreas( Qt::RightDockWidgetArea);
    ptrTrendPlotter2 = new TrendPlotter(dock,TrendPlotter::sensor13to24);

    dock->setWidget(ptrTrendPlotter2);
    addDockWidget(Qt::RightDockWidgetArea, dock);
  
     //DockWidget No 3.
    dock = new QDockWidget(QObject::tr("Sensor 25 - 36"), this);
    dock->setAllowedAreas( Qt::RightDockWidgetArea);
    ptrTrendPlotter3 = new TrendPlotter(dock,TrendPlotter::sensor25to36);

    dock->setWidget(ptrTrendPlotter3);
    addDockWidget(Qt::RightDockWidgetArea, dock);

    //DockWidget No 4
    dock = new QDockWidget(QObject::tr("Sensor 37 - 48"), this);
    dock->setAllowedAreas(Qt::RightDockWidgetArea);
    ptrTrendPlotter4 = new TrendPlotter(dock,TrendPlotter::sensor37to48);

    dock->setWidget(ptrTrendPlotter4);
    addDockWidget(Qt::RightDockWidgetArea, dock);

Connect a slot to the QDockWidget::topLevelChanged signal.
When the parameter is false, then the widget is docked and youi can changed its features to features() & (~QDockWidget:

ockWidgetFloatable).

thanks for the quick reply but my first problem is that in my code i have attached them all on leftDockArea hoping that the four widget will be forcetabbedDocks by my mainWindow but it did'nt happen the output is four dockwidget evenly displayed in my mainWindow.

please help,

Aa, ok. I see now.
Do you set fixed sizes/maximum sizez for the docks and/or widgets vontained by them?
F. e. what does the TrendPlotter constructor?

i did not set fixed sizes/maximum sizez for the docks and/or widgets vontained by them.

should i set them to some sizes so that forcetabbedDocks feature will kick in?

I have similar problem with dock widgets. AFAIK this is added as a bug, but it'll be solved in some future release :/...

Hi

I run into the same problem.
Luckily there is a solution
...
...
dock->setWidget(ptrTrendPlotter4);
addDockWidget(Qt::RightDockWidgetArea, dock);

// First give all <dock>s as dock1,2,3,4
// Then
tabifyDockWidget( dock1, dock2 );
tabifyDockWidget( dock2, dock3 );
tabifyDockWidget( dock3, dock4 );

// A cruid method but works
