+    \module table
+
+    For many applications TQTableItems are ideal for presenting and
+    editing the contents of TQTable cells. In situations where you need
+    to create very large tables you may prefer an alternative approach
+    to using TQTableItems: see the notes on large tables.
+
+    A TQTableItem contains a cell's data, by default, a string and a
+    pixmap. The table item also holds the cell's display size and how
+    the data should be aligned. The table item specifies the cell's
+    \l EditType and the editor used for in-place editing (by default a
+    TQLineEdit). If you want checkboxes use \l{TQCheckTableItem}, and if
+    you want comboboxes use \l{TQComboTableItem}. The \l EditType (set
+    in the constructor) determines whether the cell's contents may be
+    edited.
+
+    If a pixmap is specified it is displayed to the left of any text.
+    You can change the text or pixmap with setText() and setPixmap()
+    respectively. For text you can use setWordWrap().
+
+    When sorting table items the key() function is used; by default
+    this returns the table item's text(). Reimplement key() to
+    customize how your table items will sort.
+
+    Table items are inserted into a table using TQTable::setItem(). If
+    you insert an item into a cell that already contains a table item
+    the original item will be deleted.
+
+    Example:
+    \code
+    for ( int row = 0; row < table->numRows(); row++ ) {
+	for ( int col = 0; col < table->numCols(); col++ ) {
+	    table->setItem( row, col,
+		new TQTableItem( table, TQTableItem::WhenCurrent, TQString::number( row * col ) ) );
+	}
+    }
+    \endcode
+
+    You can move a table item from one cell to another, in the same or
+    a different table, using TQTable::takeItem() and TQTable::setItem()
+    but see also TQTable::swapCells().
+
+    Table items can be deleted with delete in the standard way; the
+    table and cell will be updated accordingly.
+
+    Note, that if you have a table item that is not currently in a table
+    then anything you do to that item other than insert it into a table
+    will result in undefined behaviour.
+
+    Reimplement createEditor() and setContentFromEditor() if you want
+    to use your own widget instead of a TQLineEdit for editing cell
+    contents. Reimplement paint() if you want to display custom
+    content.
+
+    It is important to ensure that your custom widget can accept the
+    keyboard focus, so that the user can use the tab key to navigate the
+    table as normal. Therefore, if the widget returned by createEditor()
+    does not itself accept the keyboard focus, it is necessary to
+    nominate a child widget to do so on its behalf. For example, a
+    TQHBox with two child TQLineEdit widgets may use one of them to
+    accept the keyboard focus:
+
+    \code
+    TQWidget* MyTableItem::createEditor() const
+    {
+        TQHBox* hbox = new TQHBox( table()->viewport() );
+        hbox->setFocusProxy(new TQLineEdit( hbox ));
+        new TQLineEdit( hbox );
+        return hbox;
+    }
+    \endcode
+
+    By default, table items may be replaced by new TQTableItems
+    during the lifetime of a TQTable. Therefore, if you create your
+    own subclass of TQTableItem, and you want to ensure that
+    this does not happen, you must call setReplaceable(FALSE)
+    in the constructor of your subclass.

+    \enum TQTableItem::EditType
+
+    \target wheneditable
+    This enum is used to define whether a cell is editable or
+    read-only (in conjunction with other settings), and how the cell
+    should be displayed.
+
+    \value Always
+    The cell always \e looks editable.
+
+    Using this EditType ensures that the editor created with
+    createEditor() (by default a TQLineEdit) is always visible. This
+    has implications for the alignment of the content: the default
+    editor aligns everything (even numbers) to the left whilst
+    numerical values in the cell are by default aligned to the right.
+
+    If a cell with the edit type \c Always looks misaligned you could
+    reimplement createEditor() for these items.
+
+    \value WhenCurrent
+    The cell \e looks editable only when it has keyboard focus (see
+    TQTable::setCurrentCell()).
+
+    \value OnTyping
+    The cell \e looks editable only when the user types in it or
+    double-clicks it. It resembles the \c WhenCurrent functionality
+    but is, perhaps, nicer.
+
+    The \c OnTyping edit type is the default when TQTableItem objects
+    are created by the convenience functions TQTable::setText() and
+    TQTable::setPixmap().
+
+    \value Never  The cell is not editable.
+
+    The cell is actually editable only if TQTable::isRowReadOnly() is
+    FALSE for its row, TQTable::isColumnReadOnly() is FALSE for its
+    column, and TQTable::isReadOnly() is FALSE.
+
+    TQComboTableItems have an isEditable() property. This property is
+    used to indicate whether the user may enter their own text or are
+    restricted to choosing one of the choices in the list.

+\endif

+    \ingroup advanced
+    \module table
+
+    A TQComboTableItem is a table item which looks and behaves like a
+    combobox. The advantage of using TQComboTableItems rather than real
+    comboboxes is that a TQComboTableItem uses far less resources than
+    real comboboxes in \l{TQTable}s. When the cell has the focus it
+    displays a real combobox which the user can interact with. When
+    the cell does not have the focus the cell \e looks like a
+    combobox. Only text items (i.e. no pixmaps) may be used in
+    TQComboTableItems.
+
+    TQComboTableItem items have the edit type \c WhenCurrent (see
+    \l{EditType}). The TQComboTableItem's list of items is provided by
+    a TQStringList passed to the constructor.
+
+    The list of items may be changed using setStringList(). The
+    current item can be set with setCurrentItem() and retrieved with
+    currentItem(). The text of the current item can be obtained with
+    currentText(), and the text of a particular item can be retrieved
+    with text().
+
+    If isEditable() is TRUE the TQComboTableItem will permit the user
+    to either choose an existing list item, or create a new list item
+    by entering their own text; otherwise the user may only choose one
+    of the existing list items.
+
+    To populate a table cell with a TQComboTableItem use
+    TQTable::setItem().
+
+    TQComboTableItems may be deleted with TQTable::clearCell().
+
+    TQComboTableItems can be distinguished from \l{TQTableItem}s and
+    \l{TQCheckTableItem}s using their Run Time Type Identification
+    number (see rtti()).

+
+    A TQCheckTableItem is a table item which looks and behaves like a
+    checkbox. The advantage of using TQCheckTableItems rather than real
+    checkboxes is that a TQCheckTableItem uses far less resources than
+    a real checkbox would in a \l{TQTable}. When the cell has the focus
+    it displays a real checkbox which the user can interact with. When
+    the cell does not have the focus the cell \e looks like a
+    checkbox. Pixmaps may not be used in TQCheckTableItems.
+
+    TQCheckTableItem items have the edit type \c WhenCurrent (see
+    \l{EditType}).
+
+    To change the checkbox's label use setText(). The checkbox can be
+    checked and unchecked with setChecked() and its state retrieved
+    using isChecked().
+
+    To populate a table cell with a TQCheckTableItem use
+    TQTable::setItem().
+
+    TQCheckTableItems can be distinguished from \l{TQTableItem}s and

+\endif
+
+    \mainclass
+    \ingroup advanced
+    \module table
+
+    TQTable is easy to use, although it does have a large API because
+    of the comprehensive functionality that it provides. TQTable
+    includes functions for manipulating \link #headers
+    headers\endlink, \link #columnsrows rows and columns\endlink,
+    \link #cells cells\endlink and \link #selections
+    selections\endlink. TQTable also provides in-place editing and
+    \link dnd.html drag and drop\endlink, as well as a useful set of
+    \link #signals signals\endlink. TQTable efficiently supports very
+    large tables, for example, tables one million by one million cells
+    are perfectly possible. TQTable is economical with memory, using
+    none for unused cells.
+
+    \code
+    TQTable *table = new TQTable( 100, 250, this );
+    table->setPixmap( 3, 2, pix );
+    table->setText( 3, 2, "A pixmap" );
+    \endcode
+
+    The first line constructs the table specifying its size in rows
+    and columns. We then insert a pixmap and some text into the \e
+    same \link #cells cell\endlink, with the pixmap appearing to the
+    left of the text. TQTable cells can be populated with
+    \l{TQTableItem}s, \l{TQComboTableItem}s or by \l{TQCheckTableItem}s.
+    By default a vertical header appears at the left of the table
+    showing row numbers and a horizontal header appears at the top of
+    the table showing column numbers. (The numbers displayed start at
+    1, although row and column numbers within TQTable begin at 0.)
+
+    If you want to use mouse tracking call setMouseTracking( TRUE ) on
+    the \e viewport; (see \link qscrollview.html#allviews
+    TQScrollView\endlink).
+
+    \img qtableitems.png Table Items
+
+    \target headers
+    \section1 Headers
+
+    TQTable supports a header column, e.g. to display row numbers, and
+    a header row, e.g to display column titles. To set row or column
+    labels use TQHeader::setLabel() on the pointers returned by
+    verticalHeader() and horizontalHeader() respectively. The vertical
+    header is displayed within the table's left margin whose width is
+    set with setLeftMargin(). The horizontal header is displayed
+    within the table's top margin whose height is set with
+    setTopMargin(). The table's grid can be switched off with
+    setShowGrid(). If you want to hide a horizontal header call
+    hide(), and call setTopMargin( 0 ) so that the area the header
+    would have occupied is reduced to zero size.
+
+    Header labels are indexed via their section numbers. Note that the
+    default behavior of TQHeader regarding section numbers is overriden
+    for TQTable. See the explanation below in the Rows and Columns
+    section in the discussion of moving columns and rows.
+
+    \target columnsrows
+    \section1 Rows and Columns
+
+    Row and column sizes are set with setRowHeight() and
+    setColumnWidth(). If you want a row high enough to show the
+    tallest item in its entirety, use adjustRow(). Similarly, to make
+    a column wide enough to show the widest item use adjustColumn().
+    If you want the row height and column width to adjust
+    automatically as the height and width of the table changes use
+    setRowStretchable() and setColumnStretchable().
+
+    Rows and columns can be hidden and shown with hideRow(),
+    hideColumn(), showRow() and showColumn(). New rows and columns are
+    inserted using insertRows() and insertColumns(). Additional rows
+    and columns are added at the  bottom (rows) or right (columns) if
+    you set setNumRows() or setNumCols() to be larger than numRows()
+    or numCols(). Existing rows and columns are removed with
+    removeRow() and removeColumn(). Multiple rows and columns can be
+    removed with removeRows() and removeColumns().
+
+    Rows and columns can be set to be moveable using
+    rowMovingEnabled() and columnMovingEnabled(). The user can drag
+    them to reorder them holding down the Ctrl key and dragging the
+    mouse. For performance reasons, the default behavior of TQHeader
+    section numbers is overridden by TQTable. Currently in TQTable, when
+    a row or column is dragged and reordered, the section number is
+    also changed to its new position. Therefore, there is no
+    difference between the section and the index fields in TQHeader.
+    The TQTable TQHeader classes do not provide a mechanism for indexing
+    independently of the user interface ordering.
+
+    The table can be sorted using sortColumn(). Users can sort a
+    column by clicking its header if setSorting() is set to TRUE. Rows
+    can be swapped with swapRows(), columns with swapColumns() and
+    cells with swapCells().
+
+    For editable tables (see setReadOnly()) you can set the read-only
+    property of individual rows and columns with setRowReadOnly() and
+    setColumnReadOnly(). (Whether a cell is editable or read-only
+    depends on these settings and the cell's \link
+    qtableitem.html#wheneditable TQTableItem::EditType\endlink.)
+
+    The row and column which have the focus are returned by
+    currentRow() and currentColumn() respectively.
+
+    Although many TQTable functions operate in terms of rows and
+    columns the indexOf() function returns a single integer
+    identifying a particular cell.
+
+    \target cells
+    \section1 Cells
+
+    All of a TQTable's cells are empty when the table is constructed.
+
+    There are two approaches to populating the table's cells. The
+    first and simplest approach is to use TQTableItems or TQTableItem
+    subclasses. The second approach doesn't use TQTableItems at all
+    which is useful for very large sparse tables but retquires you to
+    reimplement a number of functions. We'll look at each approach in
+    turn.
+
+    To put a string in a cell use setText(). This function will create
+    a new TQTableItem for the cell if one doesn't already exist, and
+    displays the text in it. By default the table item's widget will
+    be a TQLineEdit. A pixmap may be put in a cell with setPixmap(),
+    which also creates a table item if retquired. A cell may contain \e
+    both a pixmap and text; the pixmap is displayed to the left of the
+    text. Another approach is to construct a TQTableItem or TQTableItem
+    subclass, set its properties, then insert it into a cell with
+    setItem().
+
+    If you want cells which contain comboboxes use the TQComboTableItem
+    class. Similarly if you retquire cells containing checkboxes use
+    the TQCheckTableItem class. These table items look and behave just
+    like the combobox or checkbox widgets but consume far less memory.
+
+    \quotefile table/small-table-demo/main.cpp
+    \skipto int j
+    \printuntil TQCheckTableItem
+    In the example above we create a column of TQCheckTableItems and
+    insert them into the table using setItem().
+
+    TQTable takes ownership of its TQTableItems and will delete them
+    when the table itself is destroyed. You can take ownership of a
+    table item using takeItem() which you use to move a cell's
+    contents from one cell to another, either within the same table,
+    or from one table to another. (See also, swapCells()).
+
+    In-place editing of the text in TQTableItems, and the values in
+    TQComboTableItems and TQCheckTableItems works automatically. Cells
+    may be editable or read-only, see \link
+    qtableitem.html#wheneditable TQTableItem::EditType\endlink. If you
+    want fine control over editing see beginEdit() and endEdit().
+
+    The contents of a cell can be retrieved as a TQTableItem using
+    item(), or as a string with text() or as a pixmap (if there is
+    one) with pixmap(). A cell's bounding rectangle is given by
+    cellGeometry(). Use updateCell() to repaint a cell, for example to
+    clear away a cell's visual representation after it has been
+    deleted with clearCell(). The table can be forced to scroll to
+    show a particular cell with ensureCellVisible(). The isSelected()
+    function indicates if a cell is selected.
+
+    It is possible to use your own widget as a cell's widget using
+    setCellWidget(), but subclassing TQTableItem might be a simpler
+    approach. The cell's widget (if there is one) can be removed with
+    clearCellWidget().
+
+    \keyword notes on large tables
+    \target bigtables
+    \section2 Large tables
+
+    For large, sparse, tables using TQTableItems or other widgets is
+    inefficient. The solution is to \e draw the cell as it should
+    appear and to create and destroy cell editors on demand.
+
+    This approach retquires that you reimplement various functions.
+    Reimplement paintCell() to display your data, and createEditor()
+    and setCellContentFromEditor() to support in-place editing. It
+    is very important to reimplement resizeData() to have no
+    functionality, to prevent TQTable from attempting to create a huge
+    array. You will also need to reimplement item(), setItem(),
+    takeItem(), clearCell(), and insertWidget(), cellWidget() and
+    clearCellWidget(). In almost every circumstance (for sorting,
+    removing and inserting columns and rows, etc.), you also need
+    to reimplement swapRows(), swapCells() and swapColumns(), including
+    header handling.
+
+    If you represent active cells with a dictionary of TQTableItems and
+    TQWidgets, i.e. only store references to cells that are actually
+    used, many of the functions can be implemented with a single line
+    of code. (See the \l table/bigtable/main.cpp example.)
+
+    For more information on cells see the TQTableItem documenation.
+
+    \target selections
+    \section1 Selections
+
+    TQTable's support single selection, multi-selection (multiple
+    cells) or no selection. The selection mode is set with
+    setSelectionMode(). Use isSelected() to determine if a particular
+    cell is selected, and isRowSelected() and isColumnSelected() to
+    see if a row or column is selected.
+
+    TQTable's support many simultaneous selections. You can
+    programmatically select cells with addSelection(). The number of
+    selections is given by numSelections(). The current selection is
+    returned by currentSelection(). You can remove a selection with
+    removeSelection() and remove all selections with
+    clearSelection(). Selections are TQTableSelection objects.
+
+    To easily add a new selection use selectCells(), selectRow() or
+    selectColumn().
+
+    Alternatively, use addSelection() to add new selections using
+    TQTableSelection objects. The advantage of using TQTableSelection
+    objects is that you can call TQTableSelection::expandTo() to resize
+    the selection and can query and compare them.
+
+    The number of selections is given by numSelections(). The current
+    selection is returned by currentSelection(). You can remove a
+    selection with removeSelection() and remove all selections with
+    clearSelection().
+
+    \target signals
+    \section1 Signals
+
+    When the user clicks a cell the currentChanged() signal is
+    emitted. You can also connect to the lower level clicked(),
+    doubleClicked() and pressed() signals. If the user changes the
+    selection the selectionChanged() signal is emitted; similarly if
+    the user changes a cell's value the valueChanged() signal is
+    emitted. If the user right-clicks (or presses the appropriate
+    platform-specific key sequence) the contextMenuRequested() signal
+    is emitted. If the user drops a drag and drop object the dropped()
+    signal is emitted with the drop event.

+    This function returns the widget which should be used as an editor

+    into the widget created by this function.
+
+    The default functionality is as follows: if \a initFromCell is
+    TRUE or the cell has a TQTableItem and the table item's
+    TQTableItem::isReplaceable() is FALSE then the cell is asked to
+    create an appropriate editor (using TQTableItem::createEditor()).

+

+    TQTableItem::createEditor().
+
+    If you are not using \l{TQTableItem}s and you don't want to use a
+    TQLineEdit as the default editor, subclass TQTable and reimplement

+    else
+	return ...(create your own editor)
+    \endcode
+    Ownership of the editor widget is transferred to the caller.
+
+    If you reimplement this function return 0 for read-only cells. You
+    will need to reimplement setCellContentFromEditor() to retrieve
+    the data the user entered.
