QDockWidget and QListWidget for widget list (QLable, QTextEdit, ect...)

[giorgik]

Hi all, I'm a problem: I would use QDockWidget containing a list of widgets like QTextEdit and QList but I do not know how to do.
I wrote this code inside the MainWindow:

QDockWidget *dock = new QDockWidget(tr("Contenitore"), this);
 dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
 this->addDockWidget(Qt::LeftDockWidgetArea, dock);
 QListWidget *listaWid = new QListWidget(dock);

QDockWidget *dock = new QDockWidget(tr("Contenitore"), this);
 dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
 this->addDockWidget(Qt::LeftDockWidgetArea, dock);
 QListWidget *listaWid = new QListWidget(dock);

To copy to clipboard, switch view to plain text mode 

As I continue to put in a list widget QLabels and a QTextEdit?

Thanks for the help

I'm wrote

QWidget *widCentrale = new QWidget(this);
    QTextEdit *textEdit = new QTextEdit();
    QVBoxLayout *layout = new QVBoxLayout();
    layout->addWidget(textEdit);
    widCentrale->setLayout(layout);
    this->setCentralWidget(widCentrale);
 
    QDockWidget *dock = new QDockWidget(tr("Contenitore"), this);
    dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
    this->addDockWidget(Qt::LeftDockWidgetArea, dock);
    QVBoxLayout *layoutDockWid = new QVBoxLayout();
    QLabel *labelDockWid = new QLabel(tr("Una label"));
    layoutDockWid->addWidget(labelDockWid);
    QTextEdit *textEditDockWid = new QTextEdit();
    layoutDockWid->addWidget(textEditDockWid);
    dock->setLayout(layoutDockWid);

QWidget *widCentrale = new QWidget(this);
    QTextEdit *textEdit = new QTextEdit();
    QVBoxLayout *layout = new QVBoxLayout();
    layout->addWidget(textEdit);
    widCentrale->setLayout(layout);
    this->setCentralWidget(widCentrale);

    QDockWidget *dock = new QDockWidget(tr("Contenitore"), this);
    dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
    this->addDockWidget(Qt::LeftDockWidgetArea, dock);
    QVBoxLayout *layoutDockWid = new QVBoxLayout();
    QLabel *labelDockWid = new QLabel(tr("Una label"));
    layoutDockWid->addWidget(labelDockWid);
    QTextEdit *textEditDockWid = new QTextEdit();
    layoutDockWid->addWidget(textEditDockWid);
    dock->setLayout(layoutDockWid);

What is missing in the code to display layoutDockWid and then into the column labelDockWid and textEditDockWid ?

You will be seeing warnings about setting a layout on a widget that already has one.

You set the content of a QDockWidget as a single widget using QDockWidget::setWidget(). You need to wrap your QDockWidget content in a QWidget with its layout and then set that on the dock widget.

Thanks ChrisW67 for your advice I solved it:

#include "mainwindow.h"
#include <QtGui/QWidget>
#include <QtGui/QVBoxLayout>
#include <QtGui/QDockWidget>
#include <QtGui/QLabel>
#include <QtGui/QTextEdit>
 
 
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent)
{
    QWidget *widCentrale = new QWidget(this);
    QTextEdit *textEdit = new QTextEdit();
    QVBoxLayout *layout = new QVBoxLayout();
    layout->addWidget(textEdit);
    widCentrale->setLayout(layout);
    this->setCentralWidget(widCentrale);
 
    QDockWidget *dock = new QDockWidget(tr("Contenitore"), this);
    dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
    this->addDockWidget(Qt::LeftDockWidgetArea, dock);
    dock->setFeatures(QDockWidget::NoDockWidgetFeatures); // thus blocking dock widget area
 
    // container QWidget to put QVBoxLayout containing QLabel and QTextEdit
    QWidget *widDockWid = new QWidget(dock);
    QVBoxLayout *layoutDockWid = new QVBoxLayout();
    QLabel *labelDockWid = new QLabel(tr("Una label"));
    layoutDockWid->addWidget(labelDockWid);
    QTextEdit *textEditDockWid = new QTextEdit();
    layoutDockWid->addWidget(textEditDockWid);
    widDockWid->setLayout(layoutDockWid);
    dock->setWidget(widDockWid);
}

#include "mainwindow.h"

    layout->addWidget(textEdit);
    widCentrale->setLayout(layout);
    this->setCentralWidget(widCentrale);

    QDockWidget *dock = new QDockWidget(tr("Contenitore"), this);
    dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
    this->addDockWidget(Qt::LeftDockWidgetArea, dock);

    // container QWidget to put QVBoxLayout containing QLabel and QTextEdit
    QWidget *widDockWid = new QWidget(dock);
    QVBoxLayout *layoutDockWid = new QVBoxLayout();
