-
-    \brief The Calendar example shows how to create rich text content and display it using
-    a rich text editor.
-
-    \image calendar-example.png
-
-    Specifically, the example demonstrates the following:
-
-    \list
-      \li Use of a text editor with a text document
-      \li Insertion of tables and frames into a document
-      \li Navigation within a table
-      \li Insert text in different styles
-    \endlist
-
-    The rich text editor used to display the document is used within a main window
-    application.
-
-    \section1 MainWindow Class Definition
-
-    The \c MainWindow class provides a text editor widget and some controls to
-    allow the user to change the month and year shown. The font size used for the
-    text can also be adjusted.
-
-    \snippet richtext/calendar/mainwindow.h 0
-
-    The private \c insertCalendar() function performs most of the work, relying on
-    the \c fontSize and \c selectedDate variables to write useful information to
-    the \c editor.
-
-    \section1 MainWindow Class Implementation
-
-    The \c MainWindow constructor sets up the user interface and initializes
-    variables used to generate a calendar for each month.
-
-    \snippet richtext/calendar/mainwindow.cpp 0
-
-    We begin by setting default values for the selected date that will be highlighted
-    in the calendar and the font size to be used. Since we are using a QMainWindow
-    for the user interface, we construct a widget for use as the central widget.
-
-    The user interface will include a line of controls above the generated calendar;
-    we construct a label and a combobox to allow the month to be selected, and a
-    spin box for the year. These widgets are configured to provide a reasonable range
-    of values for the user to try:
-
-    \snippet richtext/calendar/mainwindow.cpp 1
-
-    We use the \c selectedDate object to obtain the current month and year, and we
-    set these in the combobox and spin box:
-
-    The font size is displayed in a spin box which we restrict to a sensible range
-    of values:
-
-    \snippet richtext/calendar/mainwindow.cpp 2
-
-    We construct an editor and use the \c insertCalendar() function to create
-    a calendar for it. Each calendar is displayed in the same text editor; in
-    this example we use a QTextBrowser since we do not allow the calendar to be
-    edited.
-
-    The controls used to set the month, year, and font size will not have any
-    effect on the appearance of the calendar unless we make some signal-slot
-    connections:
-
-    \snippet richtext/calendar/mainwindow.cpp 3
-
-    The signals are connected to some simple slots in the \c MainWindow class
-    which we will describe later.
-
-    We create layouts to manage the widgets we constructed:
-
-    \snippet richtext/calendar/mainwindow.cpp 4
-
-    Finally, the central widget is set for the window.
-
-    Each calendar is created for the editor by the \c insertCalendar() function
-    which uses the date and font size, defined by the private \a selectedDate
-    and \c fontSize variables, to produce a suitable plan for the specified
-    month and year.
-
-    \snippet richtext/calendar/mainwindow.cpp 5
-
-    We begin by clearing the editor's rich text document, and obtain a text
-    cursor from the editor that we will use to add content. We also create a
-    QDate object based on the currently selected date.
-
-    The calendar is made up of a table with a gray background color that contains
-    seven columns: one for each day of the week. It is placed in the center of the
-    page with equal space to the left and right of it. All of these properties are
-    set in a QTextTableFormat object:
-
-    \snippet richtext/calendar/mainwindow.cpp 6
-
-    Each cell in the table will be padded and spaced to make the text easier to
-    read.
-
-    We want the columns to have equal widths, so we provide a list containing
-    percentage widths for each of them and set the constraints in the
-    QTextTableFormat:
-
-    \snippet richtext/calendar/mainwindow.cpp 7
-
-    The constraints used for the column widths are only useful if the table has
-    an appropriate number of columns. With the format for the table defined, we
-    construct a new table with one row and seven columns at the current cursor
-    position:
-
-    \snippet richtext/calendar/mainwindow.cpp 8
-
-    We only need one row to start with; more can be added as we need them. Using
-    this approach means that we do not need to perform any date calculations
-    until we add cells to the table.
-
-    When inserting objects into a document with the cursor's insertion functions,
-    the cursor is automatically moved inside the newly inserted object. This means
-    that we can immediately start modifying the table from within:
-
-    \snippet richtext/calendar/mainwindow.cpp 9
-
-    Since the table has an outer frame, we obtain the frame and its format so that
-    we can customize it. After making the changes we want, we set the frame's format
-    using the modified format object. We have given the table an outer border one
-    pixel wide.
-
-    \snippet richtext/calendar/mainwindow.cpp 10
-
-    In a similar way, we obtain the cursor's current character format and
-    create customized formats based on it.
-
-    We do not set the format on the cursor because this would change the default
-    character format; instead, we use the customized formats explicitly when we
-    insert text. The following loop inserts the days of the week into the table
-    as bold text:
-
-    \snippet richtext/calendar/mainwindow.cpp 11
-
-    For each day of the week, we obtain an existing table cell in the first row
-    (row 0) using the table's \l{QTextTable::cellAt()}{cellAt()} function. Since
-    we start counting the days of the week at day 1 (Monday), we subtract 1 from
-    \c weekDay to ensure that we obtain the cell for the correct column of the
-    table.
-
-    Before text can be inserted into a cell, we must obtain a cursor with the
-    correct position in the document. The cell provides a function for this
-    purpose, and we use this cursor to insert text using the \c boldFormat
-    character format that we created earlier:
-
-    \snippet richtext/calendar/mainwindow.cpp 12
-
-    Inserting text into document objects usually follows the same pattern.
-    Each object can provide a new cursor that corresponds to the first valid
-    position within itself, and this can be used to insert new content. We
-    continue to use this pattern as we insert the days of the month into the
-    table.
-
-    Since every month has more than seven days, we insert a single row to begin
-    and add days until we reach the end of the month. If the current date is
-    encountered, it is inserted with a special format (created earlier) that
-    makes it stand out:
-
-    \snippet richtext/calendar/mainwindow.cpp 13
-
-    We add a new row to the table at the end of each week only if the next week
-    falls within the currently selected month.
-
-    For each calendar that we create, we change the window title to reflect the
-    currently selected month and year:
-
-    \snippet richtext/calendar/mainwindow.cpp 14
-
-    The \c insertCalendar() function relies on up-to-date values for the month,
-    year, and font size. These are set in the following slots:
-
-    \snippet richtext/calendar/mainwindow.cpp 15
-
-    The \c setFontSize() function simply changes the private \c fontSize variable
-    before updating the calendar.
-
-    \snippet richtext/calendar/mainwindow.cpp 16
-
-    The \c setMonth slot is called when the QComboBox used to select the month is
-    updated. The value supplied is the currently selected row in the combobox.
-    We add 1 to this value to obtain a valid month number, and create a new QDate
-    based on the existing one. The calendar is then updated to use this new date.
-
-    \snippet richtext/calendar/mainwindow.cpp 17
-
-    The \c setYear() slot is called when the QDateTimeEdit used to select the
-    year is updated. The value supplied is a QDate object; this makes
-    the construction of a new value for \c selectedDate simple. We update the
-    calendar afterwards to use this new date.
