Help with Docked Widget!

Hi everybody,
If I make a Widget in QtDesigner, how can I put it into a MainWindow, like a Docked Widget ?
Suppose the Widget has other components like Buttons, lineEdits.

I have read and tried using the QDockWidget with simple samples, adding a textedit, a lineEdit, but I cant do what I want, using a widget previously made in a separate class.

Thanks and sorry, my english writing is not the best.

So maybe first clearly state what you want and then we'll try to help you. Do you actually want to use a dock widget or is it just an example of some behaviour you want?

Thanks for your answer wysota.
Well, I want to make an application with a textedit and a docket widget to the right side of the Window, the docked will contain a widget with some buttons, and the user will be able to hide, move, and close the docket.

I suggest you implement the two widgets (main window and the contents of the dock) in Designer and them create a dock widget in code and attach it to your main window.

Hi,

I use a few docked widgets in my MDI application. This is the code I wrote to do a listbox dock widget and dock it at the bottom of the main window :

Code:

---

m_plistWidget = new QCustomListWidget;
	QDockWidget* dockwidget = new QDockWidget( tr("Information"), this);
	dockwidget->setWidget(m_plistWidget);
	dockwidget->setAllowedAreas(Qt::BottomDockWidgetArea | Qt::TopDockWidgetArea);
	this->addDockWidget(Qt::BottomDockWidgetArea, dockwidget);

---

QCustomListWidget is a widget I did that is derived from QListWidget but has buttons as well.

Thanks for your answers wysota and Steve.

I made the MainWindow and the other Widget using Qt Desginer.
Now, I have MainWindow.ui and Editor.ui.

The MainWindow have a Menu, and it will contain a dock widget with the editor widget.

This the MainWindow.h code:

Code:

---

#include <QMainWindow>
#include <QDockWidget>
#include "ui_MainWindow.h"
#include "editor.h"
 
class MainWindow : public QMainWindow, private Ui::MainWindow
{
  Q_OBJECT
public:
  QDockWidget* dock; // the dock that will contain the editor widget
  Editor* editor; //the widget with the textedit
   MainWindow(QWidget* parent = 0, Qt::WFlags fl = 0 );
  ~MainWindow();
public slots:
 
 
};

---

And this is the MainWindow.cpp

Code:

---

#include "mainwindow.h"
 
MainWindow::MainWindow(QWidget* parent, Qt::WFlags fl)
: QMainWindow( parent, fl ), Ui::MainWindow()
{
	setupUi(this);
	dock = new QDockWidget(tr("Editor"),this);
	editor = new Editor(dock);
	dock->setWidget(editor);
	addDockWidget(Qt::RightDockWidgetArea, dock);
}

---

This the code of the Editor, may be will be useful.

Code:

---

#include <QWidget>
#include "ui_editor.h"
class Editor : public QWidget, private Ui::Form
{
  Q_OBJECT
public:
  Editor(QWidget* parent = 0, Qt::WFlags fl = 0 );
  ~Editor();
public slots:
};

---

Editor.cpp

Code:

---

#include "editor.h"
 
Editor::Editor(QWidget* parent, Qt::WFlags fl)
: QWidget( parent, fl ), Ui::Form()
{
	setupUi(this);
}

---

When I compile the project it works fine, without errors, but the MainWindow doesn't have the docked widget inside. What I'm doing wrong?
I only got the MainWindow with the Menu. The dock widget doesn't exist.

thanks!

You might need to call show() on the dock widget, although I'm not sure of that. I don't remember doing that with my dock widgets.

Thanks, I tried with that, but the dock doesn't show it.

I use something more like the following, and it works just fine. I even pass the dock pointer thru plugins and it works great. Mostly, I don't use "this" anywhere.

Code:

---

#include "mainwindow.h"
 
MainWindow::MainWindow(QWidget* parent, Qt::WFlags fl)
: QMainWindow( parent, fl )
{
	setupUi(this);
	dock = new QDockWidget(tr("Editor"));
	editor = new Editor();
	dock->setWidget(editor);
	addDockWidget(Qt::RightDockWidgetArea, dock);
}

---

And then the MainWindow.h looks more like :

Code:

---

class MainWindow : public QMainWindow, public Ui::MainWindow

---

Note that Ui::MainWindow is public.
