@vale88 You should at least post your code which is executed if you double click. Else how could anybody know why that happens?

@jsulm

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QDockWidget>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    QDockWidget * dock = new QDockWidget;
    dock->setFloating(true);
    dock->show();
}

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

I wrote only this...I think it's a property of the dock

@vale88 hi. I think you need to first name ur title like this

    QDockWidget * dock = new QDockWidget(tr("YourTitle"), this);

And I prefer to look into this example I think it will be very helpful for u. You can reach it using examples on Qt.
