-    \title Getting Started Programming with Qt Widgets
-
-    In this topic, we teach basic Qt knowledge by implementing a simple Notepad
-    application using C++ and the \l{Qt Widgets} module. The application is a
-    small text editor which allows you to create a text file, save it, print it,
-    or reopen and edit it again. You can also set the font to be used.
-
-    \image notepad1.png "Notepad application"
-
-    You can find the final Notepad source files in the qtdoc repository in the
-    snippets/widgets-tutorial/notepad directory. You can either fetch
-    the Qt 5 sources from Qt Project or install them as part of Qt 5.
-
-    \section1 Creating the Notepad Project
-
-    Setting up a new project in Qt Creator is aided by a wizard that guides you
-    step-by-step through the project creation process. The wizard prompts you
-    to enter the settings needed for that particular type of project and creates
-    the project for you.
-
-    \image notepad2.png "Qt Creator New File or Project dialog"
-
-    To create the Notepad project, select \b File > \b{New File or Project} >
-    \b Applications > \b {Qt Widgets Application} > \b Choose, and follow the
-    instructions of the wizard. In the \b {Class Information} dialog, type
-    \b Notepad as the class name and select \b QMainWindow as the base class.
-
-    \image notepad3.png "Class Information Dialog"
-
-    The \b {Qt Widgets Application} wizard creates a project that contains a main
-    source file and a set of files that specify a user interface (Notepad
-    widget):
-
-    \list
-        \li notepad.pro - the project file.
-        \li main.cpp - the main source file for the application.
-        \li notepad.cpp - the source file of the notepad class of the Notepad
-            widget.
-        \li notepad.h - the header file of the notepad class for the Notepad
-            widget.
-        \li notepad.ui - the UI form for the Notepad widget.
-    \endlist
-
-    The .cpp, .h, and .ui files come with the necessary boiler plate code for
-    you to be able to build and run the project. The .pro file is complete.
-    We will take a closer look at the file contents in the following sections.
-
-    \b{Learn More}
-
-    \table
-        \header
-            \li About
-            \li Here
-        \row
-            \li Using Qt Creator
-            \li \l{Qt Creator Manual}{Qt Creator}
-        \row
-            \li Creating other kind of applications with Qt Creator
-            \li \l{Qt Creator: Tutorials}{Qt Creator Tutorials}
-    \endtable
-
-
-    \section1 Main Source File
-
-    The wizard generates the following code in the main.cpp file:
-
-    \snippet snippets/widgets-tutorial/notepad/main.cpp all
-
-    We will go through the code line by line. The following lines include
-    the header files for the Notepad widget and QApplication. All Qt classes
-    have a header file named after them.
-
-    \snippet snippets/widgets-tutorial/notepad/main.cpp 1
-
-    The following line defines the main function that is the entry point for
-    all C and C++  based applications:
-
-    \snippet snippets/widgets-tutorial/notepad/main.cpp 2
-
-    The following line creates a QApplication object. This object manages
-    application-wide resources and is necessary to run any Qt program
-    that uses Qt Widgets. It constructs an application object with \c argc
-    command line arguments run in \c argv. (For GUI applications that do not
-    use Qt Widgets, you can use QGuiApplication instead.)
-
-    \snippet snippets/widgets-tutorial/notepad/main.cpp 3
-
-    The following line creates the Notepad object. This is the object for
-    which the wizard
-    created the class and the UI file. The user interface contains visual
-    elements that are called \c widgets in Qt. Examples of widgets are text
-    edits, scroll bars, labels, and radio buttons. A widget can also be a
-    container for other widgets; a dialog or a main application window, for
-    example.
-
-    \snippet snippets/widgets-tutorial/notepad/main.cpp 4
-
-    The following line shows the Notepad widget on the screen in its own
-    window. Widgets can also function as containers. An example of this
-    is QMainWindow which often contains several types of widgets. Widgets
-    are not visible by default; the function \l{QWidget::}{show()} makes
-    the widget visible.
-
-    \snippet snippets/widgets-tutorial/notepad/main.cpp 5
-
-    The following line makes the QApplication enter its event loop. When a Qt
-    application is running, events are generated and sent to the
-    widgets of the application. Examples of events are mouse presses
-    and key strokes.
-
-    \snippet snippets/widgets-tutorial/notepad/main.cpp 6
-
-    \b{Learn More}
-
-    \table
-        \header
-            \li About
-            \li Here
-        \row
-            \li Widgets and Window Geometry
-            \li \l{Window and Dialog Widgets}
-        \row
-            \li Events and event handling
-            \li \l{The Event System}
-    \endtable
-
-    \section1 Designing a UI
-
-    The wizard generates a user interface definition in XML format: notepad.ui.
-    When you open the notepad.ui file in Qt Creator, it automatically opens
-    in the integrated Qt Designer.
-
-    When you build the application, Qt Creator launches the Qt
-    \l{User Interface Compiler (uic)} that reads the .ui file and creates a
-    corresponding C++ header file, ui_notepad.h.
-
-    \section2 Using Qt Designer
-
-    The wizard creates an application that uses a QMainWindow. It has its own
-    layout to which you can add a menu bar, dock widgets, toolbars, and a
-    status bar. The center area can be occupied by any kind of widget. The
-    wizard places the Notepad widget there.
-
-    To add widgets in Qt Designer:
-
-    \list 1
-        \li In the Qt Creator \b Editor mode, double-click the notepad.ui file
-            in the \b Projects view to launch the file in the integrated Qt
-            Designer.
-        \li Drag and drop widgets Text Edit (QTextEdit) to the form.
-        \li Press \b {Ctrl+A} (or \b {Cmd+A}) to select the widgets and click
-            \b {Lay out Vertically} (or press \b {Ctrl+L}) to apply a vertical
-            layout (QVBoxLayout).
-        \li Press \b {Ctrl+S} (or \b {Cmd+S}) to save your changes.
-    \endlist
-
-    The UI now looks as follows in Qt Designer:
-
-    \image notepad4.png
-
-    You can view the generated XML file in the code editor:
-
-    \quotefromfile snippets/widgets-tutorial/notepad/notepad.ui
-
-    \printuntil QMenuBar
-    \dots
-
-    The following line contains the XML declaration, which specifies the XML
-    version and character encoding used in the document:
-
-    \code
-    <?xml version="1.0" encoding="UTF-8"?>
-    \endcode
-
-    The rest of the file specifies an \c ui element that defines a Notepad
-    widget:
-
-    \code
-    <ui version="4.0">
-    \endcode
-
-    The UI file is used together with the header and source file of the Notepad
-    class. We will look at the rest of the UI file in the later sections.
-
-    \section2 Notepad Header File
-
-    The wizard generated a header file for the Notepad class that has the
-    necessary #includes, a constructor, a destructor, and the Ui object. The
-    file looks as follows:
-
-    \snippet snippets/gs/notepad1.h all
-
-    The following line includes QMainWindow that provides a main application
-    window:
-
-    \snippet snippets/gs/notepad1.h 1
-
-    The following lines declare the Notepad class in the Ui namespace, which is the
-    standard namespace for the UI classes generated from .ui files by the
-    \c uic tool:
-
-    \snippet snippets/gs/notepad1.h 2
-
-    The class declaration contains the \c Q_OBJECT macro. It must come first in the class
-    definition, and declares our class as a QObject. Naturally, it must also
-    inherit from QObject. A QObject adds several abilities to a normal C++
-    class. Notably, the class name and slot names can be
-    queried at runtime. It is also possible to query a slot's
-    parameter types and invoke it.
-
-    \snippet snippets/gs/notepad1.h 3
-
-    The following lines declare a constructor that has a default argument
-    called \c parent.
-    The value 0 indicates that the widget has no parent (it is a top-level
-    widget).
-
-    \snippet snippets/gs/notepad1.h 4
-
-    The following line declares a virtual destructor to free the resources that were
-    acquired by the object during its life-cycle. According to the C++
-    naming convention, destructors have the same name as the class they are
-    associated with, prefixed with a tilde (~). In QObject, destructors are
-    virtual to ensure that the destructors of derived classes are invoked
-    properly when an object is deleted through a pointer-to-base-class.
-
-    \snippet snippets/gs/notepad1.h 5
-
-    The following lines declare a member variable which is a pointer to the Notepad UI
-    class. A member variable is associated with a specific class, and accessible
-    for all its methods.
-
-    \snippet snippets/gs/notepad1.h 6
-
-    \section2 Notepad Source File
-
-    The source file that the wizard generated for the Notepad class looks as
-    follows:
-
-    \snippet snippets/gs/notepad1.cpp all
-
-    The following lines include the Notepad class header file that was generated
-    by the wizard and the UI header file that was generated by the \c uic tool:
-
-    \snippet snippets/gs/notepad1.cpp 0
-
-    The following line  defines the \c {Notepad} constructor:
-
-    \snippet snippets/gs/notepad1.cpp 1
-
-    The following line  calls the QMainWindow constructor, which is the base
-    class for the Notepad class:
-
-    \snippet snippets/gs/notepad1.cpp 2
-
-    The following line  creates the UI class instance and assigns it to the
-    \c ui member:
-
-    \snippet snippets/gs/notepad1.cpp 3
-
-    The following line  sets up the UI:
-
-    \snippet snippets/gs/notepad1.cpp 4
-
-    In the destructor, we delete the \c ui:
-
-    \snippet snippets/gs/notepad1.cpp 5
-
-    In order to have the text edit field occupy the whole screen, we add
-    \c setCentralWidget to the main window.
-
-    \snippet snippets/widgets-tutorial/notepad/notepad.cpp 1
-
-    \section2 Project File
-
-    The wizard generates the following project file, \c {notepad.pro}, for us:
-
-    \quotefile snippets/widgets-tutorial/notepad/notepad.pro
-
-    The project file specifies the application name and the \c qmake template to
-    use for generating the project, as well as the source, header, and UI files
-    included in the project.
-
-    You could also use \c qmake's \c -project option to generate the \.pro file. Although,
-    in that case, you have to remember to add the line \c{QT += widgets} to the generated
-    file in order to link against the Qt Widgets Module.

-
-    \section1 Adding User Interaction
-
-
-    To add functionality to the editor, we start by adding menu items and buttons on a toolbar.
-
-    Click on "Type Here", and add the options New, Open, Save, Save as, Print
-    and Exit. This creates 5 lines in the Action Editor below.  To connect the
-    actions to slots, right-click an action and select Go to slot > triggered(),
-    and complete the code for that given slot.
-
-    If we also want to add the actions to a toolbar, we can assign an icon
-    to each QAction, and then drag the QAction to the toolbar. You assign an icon
-    by entering an icon name in the Icon property of the action concerned. When the QAction
-    has been dragged to the toolbar, clicking the icon will launch the associated
-    slot.
-
-    Complete the method \c on_actionNew_triggered() :
-
-    \snippet snippets/widgets-tutorial/notepad/notepad.cpp 2
-
-    \c current_file is a global variable containing the file presently being edited.
-    It is defined in the private part of notepad.h:
-
-    \snippet snippets/widgets-tutorial/notepad/notepad.h 6
-
-    \c setText("") clears the text buffer.
-
-    \section2 Opening a file
-
-    In \c notepad.ui, right click on \c actionOpen and select \c {Go to slot}
-
-    Complete method \c on_actionOpen_triggered().
-
-    \snippet snippets/widgets-tutorial/notepad/notepad.cpp 3
-
-    \c QFileDialog::getOpenFileName opens a dialog enabling you to select a file.
-    QFile object \c myfile has the selected \c file_name as parameter.
-    We store the selected file also into the global variable \c current_file for later purposes.
-    We open the file with \c file.open as a readonly text file. If it
-    cannot be opened, a warning is issued, and the program stops.
-
-    We define a QTextStream \c instream for parameter \c myfile.
-    The contents of file \c myfile is copied into QString \a text.
-    \c setText(text) fille the buffer of our editor with \c text.
-
-    \c section2 Saving a file
-
-    We create the method for saving a file in the same way as for \l {Opening a file},
-    by right clicking on \c actionSave, and selecting \c {Go to Slot}.
-
-    \snippet snippets/widgets-tutorial/notepad/notepad.cpp 4
-
-    QFile object \c myfile is linked to global variable \c current_file, the variable that
-    contains the file we were working with.
-    If we cannot open \c myfile, an error message is issued and the method stops.
-    We create a QTextStream \c outstream. The contents of the editor buffer is converted
-    to plain text, and then written to \c outstream.
-
-    \c section2 Saving a file with \c {Save as}
-
-    \snippet snippets/widgets-tutorial/notepad/notepad.cpp 5
-
-    This is the same procedure as for \c {Saving a file}, the only difference
-    being that here you need to enter a new file name for the file to
-    be created.
-
-
-    \section2 Print a file
-
-    If you want to use print functionalities, you need to add \c printsupport to
-    the project file:
-
-    QT       += core gui printsupport
-
-    We declare a QPrinter object called \c printer.
-    We launch a printer dialog box and store the selected printer in object \c printer.
-    If we clicked on \c Cancel and did not select a printer, the methods returns.
-    The actual printer command is given with \a ui->textEdit->print with our QPrinter
-    object as parameter.
-
-    \section2 Select a font
-
-        \snippet snippets/widgets-tutorial/notepad/notepad.cpp 7
-
-    We declare a boolean indicating if we did select a font with QFontDialog. If so, we
-    set the font with \c ui->textEdit->setFont(myfont).
-
-    \section2 Copy, cut, paste, undo, redo
-
-    If you select some text, and want to copy it to the clipboard,
-    you call the appropriate method of ui->textEdit. The same counts
-    for cut, paste, undo, and redo.
-
-    This table shows the method name to use.
-
-    \table
-    \header
-        \li Task
-        \li Method called
-    \row
-        \li Copy
-        \li ui->textEdit->copy()
-    \row
-        \li Cut
-        \li ui->textEdit->cut()
-    \row
-        \li Paste
-        \li ui->textEdit->paste()
-    \row
-        \li Undo
-        \li ui->textEdit->undo()
-    \row
-        \li Redo
-        \li ui->textEdit->redo()
-    \endtable
-
-    This project contains the following files:
-
-    \list
-        \li {main.cpp}
-        \li {notepad.cpp}
-        \li {notepad.h}
-        \li {notepad.pro}
-        \li {notepad.ui}

-               \l{Internationalization with Qt}
-    \endtable
-
-    \section1 Building and Running Notepad
-
-    Now that you have all the necessary files, select \b Build >
-    \b {Build Project Notepad} to build and run the application. Qt Creator
-    uses \c qmake and \c make to create an executable in the directory
-    specified in the build settings of the project and runs it.
-
-    \section2 Building and Running from the Command Line
-
-    To build the application from the command line, switch to the
-    directory in which you have the \c .cpp file of the application and add the
-    project file (suffixed .pro) described earlier. The following shell commands
-    then build the application:
-
-    \code
-        qmake
-        make (or nmake on Windows)
-    \endcode
-
-    The commands create an executable in the project directory. The \c qmake tool reads the
-    project file and produces a \c Makefile with instructions on how to build the application.
-    The \c make tool (or the \c nmake tool) then reads the \c Makefile and produces the executable
-    binary.
