+    \class QDialog
+    \brief The QDialog class is the base class of dialog windows.
+
+    \ingroup dialog-classes
+    \ingroup abstractwidgets
+
+
+    A dialog window is a top-level window mostly used for short-term
+    tasks and brief communications with the user. QDialogs may be
+    modal or modeless. QDialogs can
+    provide a \link #return return
+    value\endlink, and they can have \link #default default
+    buttons\endlink. QDialogs can also have a QSizeGrip in their
+    lower-right corner, using setSizeGripEnabled().
+
+    Note that QDialog (and any other widget that has type \c Qt::Dialog) uses
+    the parent widget slightly differently from other classes in Qt. A
+    dialog is always a top-level widget, but if it has a parent, its
+    default location is centered on top of the parent's top-level widget
+    (if it is not top-level itself). It will also share the parent's
+    taskbar entry.
+
+    Use the overload of the QWidget::setParent() function to change
+    the ownership of a QDialog widget. This function allows you to
+    explicitly set the window flags of the reparented widget; using
+    the overloaded function will clear the window flags specifying the
+    window-system properties for the widget (in particular it will
+    reset the Qt::Dialog flag).
+
+    \section1 Modal Dialogs
+
+    A \bold{modal} dialog is a dialog that blocks input to other
+    visible windows in the same application. Dialogs that are used to
+    request a file name from the user or that are used to set
+    application preferences are usually modal. Dialogs can be
+    \l{Qt::ApplicationModal}{application modal} (the default) or
+    \l{Qt::WindowModal}{window modal}.
+
+    When an application modal dialog is opened, the user must finish
+    interacting with the dialog and close it before they can access
+    any other window in the application. Window modal dialogs only
+    block access to the window associated with the dialog, allowing
+    the user to continue to use other windows in an application.
+
+    The most common way to display a modal dialog is to call its
+    exec() function. When the user closes the dialog, exec() will
+    provide a useful \link #return return value\endlink. Typically,
+    to get the dialog to close and return the appropriate value, we
+    connect a default button, e.g. \gui OK, to the accept() slot and a
+    \gui Cancel button to the reject() slot.
+    Alternatively you can call the done() slot with \c Accepted or
+    \c Rejected.
+
+    An alternative is to call setModal(true) or setWindowModality(),
+    then show(). Unlike exec(), show() returns control to the caller
+    immediately. Calling setModal(true) is especially useful for
+    progress dialogs, where the user must have the ability to interact
+    with the dialog, e.g.  to cancel a long running operation. If you
+    use show() and setModal(true) together to perform a long operation,
+    you must call QApplication::processEvents() periodically during
+    processing to enable the user to interact with the dialog. (See
+    QProgressDialog.)
+
+    \section1 Modeless Dialogs
+
+    A \bold{modeless} dialog is a dialog that operates
+    independently of other windows in the same application. Find and
+    replace dialogs in word-processors are often modeless to allow the
+    user to interact with both the application's main window and with
+    the dialog.
+
+    Modeless dialogs are displayed using show(), which returns control
+    to the caller immediately.
+
+    If you invoke the \l{QWidget::show()}{show()} function after hiding
+    a dialog, the dialog will be displayed in its original position. This is
+    because the window manager decides the position for windows that
+    have not been explicitly placed by the programmer. To preserve the
+    position of a dialog that has been moved by the user, save its position
+    in your \l{QWidget::closeEvent()}{closeEvent()}  handler and then
+    move the dialog to that position, before showing it again.
+
+    \target default
+    \section1 Default Button
+
+    A dialog's \e default button is the button that's pressed when the
+    user presses Enter (Return). This button is used to signify that
+    the user accepts the dialog's settings and wants to close the
+    dialog. Use QPushButton::setDefault(), QPushButton::isDefault()
+    and QPushButton::autoDefault() to set and control the dialog's
+    default button.
+
+    \target escapekey
+    \section1 Escape Key
+
+    If the user presses the Esc key in a dialog, QDialog::reject()
+    will be called. This will cause the window to close: The \link
+    QCloseEvent close event \endlink cannot be \link
+    QCloseEvent::ignore() ignored \endlink.
+
+    \section1 Extensibility
+
+    Extensibility is the ability to show the dialog in two ways: a
+    partial dialog that shows the most commonly used options, and a
+    full dialog that shows all the options. Typically an extensible
+    dialog will initially appear as a partial dialog, but with a
+    \gui More toggle button. If the user presses the \gui More button down,
+    the dialog is expanded. The \l{Extension Example} shows how to achieve
+    extensible dialogs using Qt.
+
+    \target return
+    \section1 Return Value (Modal Dialogs)
+
+    Modal dialogs are often used in situations where a return value is
+    required, e.g. to indicate whether the user pressed \gui OK or
+    \gui Cancel. A dialog can be closed by calling the accept() or the
+    reject() slots, and exec() will return \c Accepted or \c Rejected
+    as appropriate. The exec() call returns the result of the dialog.
+    The result is also available from result() if the dialog has not
+    been destroyed.
+
+    In order to modify your dialog's close behavior, you can reimplement
+    the functions accept(), reject() or done(). The
+    \l{QWidget::closeEvent()}{closeEvent()} function should only be
+    reimplemented to preserve the dialog's position or to override the
+    standard close or reject behavior.
