Advanced Docking System for Qt

Qt Advanced Docking System lets you create customizable layouts using a full featured window docking system similar to what is found in many popular integrated development environements (IDEs) such as Visual Studio. Everything is implemented with standard Qt functionality without any platform specific code. Basic usage of QWidgets and QLayouts and using basic styles as much as possible.

This work is based on and inspired by the Advanced Docking System for Qt from Manuel Freiholz. I did an almost complete rewrite of his code to improve code quality, readibility and to fix all issues from the issue tracker of his docking system project.

The following video gives a first impression what is possible with the Advanced Docking System for Qt.

Features

Docking everywhere - no central widget

There is no central widget like in the Qt docking system. You can dock on every border of the main window or you can dock into each dock area - so you are free to dock almost everywhere.

Docking inside floating windows

There is no difference between the main window and a floating window. Docking into floating windows is supported.

Grouped dragging

When dragging the titlebar of a dock, all the tabs that are tabbed with it are going to be dragged. So you can move complete groups of tabbed widgets into a floating widget or from one dock area to another one.

Perspectives for fast switching of the complete main window layout

A perspective defines the set and layout of dock windows in the main window. You can save the current layout of the dockmanager into a named perspective to make your own custom perspective. Later you can simply select a perspective from the perspective list to quickly switch the complete main window layout.

Tested Compatible Environments

Windows

Windows 10

The library was developed on and for Windows. It is used in a commercial Windows application and is therefore constantly tested.

macOS

macOS

The application can be compiled for macOS. A user reported, that the library works on macOS. If have not tested it.

Linux

Ubuntu

The application can be compiled for Linux and has been developed and tested with Kubuntu 18.04.

Build

Open the ads.pro with QtCreator and start the build, that's it. You can run the demo project and test it yourself.

Getting started / Example

The following example shows the minimum code required to use the advanced Qt docking system.

MainWindow.h

#include <QMainWindow>
#include "DockManager.h"

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();

private:
    Ui::MainWindow *ui;
    
    // The main container for docking
    ads::CDockManager* m_DockManager;
};

MainWindow.cpp

#include "MainWindow.h"
#include "ui_MainWindow.h"

#include <QLabel>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    // Create the dock manager. Because the parent parameter is a QMainWindow
    // the dock manager registers itself as the central widget.
    m_DockManager = new ads::CDockManager(this);

    // Create example content label - this can be any application specific
    // widget
    QLabel* l = new QLabel();
    l->setWordWrap(true);
    l->setAlignment(Qt::AlignTop | Qt::AlignLeft);
    l->setText("Lorem ipsum dolor sit amet, consectetuer adipiscing elit. ");

    // Create a dock widget with the title Label 1 and set the created label
    // as the dock widget content
    ads::CDockWidget* DockWidget = new ads::CDockWidget("Label 1");
    DockWidget->setWidget(l);

    // Add the toggleViewAction of the dock widget to the menu to give
    // the user the possibility to show the dock widget if it has been closed
    ui->menuView->addAction(DockWidget->toggleViewAction());

    // Add the dock widget to the top dock widget area
    m_DockManager->addDockWidget(ads::TopDockWidgetArea, DockWidget);
}

MainWindow::~MainWindow()
{
    delete ui;
}

Alternative Docking System Implementations

If this Qt Advanced Docking System does not fit to your needs you may consider some of the alternative docking system solutions for Qt.

KDDockWidgets

This is an advanced docking framework for Qt from KDAB. The interesting thing is, that they separated GUI code from logic, so they can easily provide a QtQuick backend in the future.
