+    This event handler can be reimplemented in a subclass to receive

+
+    A paint event is a request to tqrepaint all or part of the widget.
+    It can happen as a result of tqrepaint() or update(), or because the
+    widget was obscured and has now been uncovered, or for many other
+    reasons.
+
+    Many widgets can simply tqrepaint their entire surface when asked
+    to, but some slow widgets need to optimize by painting only the
+    requested region: TQPaintEvent::region(). This speed optimization
+    does not change the result, as painting is clipped to that region
+    during event processing. TQListView and TQCanvas do this, for
+    example.
+
+    TQt also tries to speed up painting by merging multiple paint
+    events into one. When update() is called several times or the
+    window system sends several paint events, TQt merges these events
+    into one event with a larger region (see TQRegion::unite()).
+    tqrepaint() does not permit this optimization, so we suggest using
+    update() when possible.
+
+    When the paint event occurs, the update region has normally been
+    erased, so that you're painting on the widget's background. There
+    are a couple of exceptions and TQPaintEvent::erased() tells you
+    whether the widget has been erased or not.
+
+    The background can be set using setBackgroundMode(),
+    setPaletteBackgroundColor() or setBackgroundPixmap(). The
+    documentation for setBackgroundMode() elaborates on the
+    background; we recommend reading it.

+    reasons.
+
+    Many widgets can simply tqrepaint their entire surface when asked

+    does not change the result, as painting is clipped to that region

+    events into one. When update() is called several times or the
+    window system sends several paint events, TQt merges these events
+    into one event with a larger region (see TQRegion::unite()).
+    tqrepaint() does not permit this optimization, so we suggest using
+    update() when possible.
+
+    When the paint event occurs, the update region has normally been

+    \class TQGridLayout
+
+    \brief The TQGridLayout class lays out widgets in a grid.
+
+    \ingroup geomanagement
+    \ingroup appearance
+    \mainclass
+
+    TQGridLayout takes the space made available to it (by its tqparent
+    tqlayout or by the mainWidget()), divides it up into rows and
+    columns, and puts each widget it manages into the correct cell.
+
+    Columns and rows behave identically; we will discuss columns, but
+    there are equivalent functions for rows.
+
+    Each column has a minimum width and a stretch factor. The minimum
+    width is the greatest of that set using addColSpacing() and the
+    minimum width of each widget in that column. The stretch factor is
+    set using setColStretch() and determines how much of the available
+    space the column will get over and above its necessary minimum.
+
+    Normally, each managed widget or tqlayout is put into a cell of its
+    own using addWidget(), addLayout() or by the \link
+    TQLayout::setAutoAdd() auto-add facility\endlink. It is also
+    possible for a widget to occupy multiple cells using
+    addMultiCellWidget(). If you do this, TQGridLayout will guess how
+    to distribute the size over the columns/rows (based on the stretch
+    factors).
+
+    To remove a widget from a tqlayout, call remove(). Calling
+    TQWidget::hide() on a widget also effectively removes the widget
+    from the tqlayout until TQWidget::show() is called.
+
+    This illustration shows a fragment of a dialog with a five-column,
+    three-row grid (the grid is shown overlaid in magenta):
+
+    \img gridtqlayout.png
+
+    Columns 0, 2 and 4 in this dialog fragment are made up of a
+    TQLabel, a TQLineEdit, and a TQListBox. Columns 1 and 3 are
+    placeholders made with addColSpacing(). Row 0 consists of three
+    TQLabel objects, row 1 of three TQLineEdit objects and row 2 of
+    three TQListBox objects. We used placeholder columns (1 and 3) to
+    get the right amount of space between the columns.
+
+    Note that the columns and rows are not equally wide or tall. If
+    you want two columns to have the same width, you must set their
+    minimum widths and stretch factors to be the same yourself. You do
+    this using addColSpacing() and setColStretch().
+
+    If the TQGridLayout is not the top-level tqlayout (i.e. does not
+    manage all of the widget's area and tqchildren), you must add it to
+    its tqparent tqlayout when you create it, but before you do anything
+    with it. The normal way to add a tqlayout is by calling
+    parentLayout-\>addLayout().
+
+    Once you have added your tqlayout you can start putting widgets and
+    other layouts into the cells of your grid tqlayout using
+    addWidget(), addLayout() and addMultiCellWidget().
+
+    TQGridLayout also includes two margin widths: the border and the
+    spacing. The border is the width of the reserved space along each
+    of the TQGridLayout's four sides. The spacing is the width of the
+    automatically allocated spacing between neighboring boxes.
+
+    Both the border and the spacing are parameters of the constructor
+    and default to 0.

+    \class TQBoxLayout
+
+    \brief The TQBoxLayout class lines up child widgets horizontally or
+    vertically.
+
+    \ingroup geomanagement
+    \ingroup appearance
+
+    TQBoxLayout takes the space it gets (from its tqparent tqlayout or from
+    the mainWidget()), divides it up into a row of boxes, and makes
+    each managed widget fill one box.
+
+    \img qhbox-m.png Horizontal box with five child widgets
+
+    If the TQBoxLayout's orientation is \c Horizontal the boxes are
+    placed in a row, with suitable sizes. Each widget (or other box)
+    will get at least its minimum size and at most its maximum size.
+    Any excess space is shared according to the stretch factors (more
+    about that below).
+
+    \img qvbox-m.png Vertical box with five child widgets
+
+    If the TQBoxLayout's orientation is \c Vertical, the boxes are
+    placed in a column, again with suitable sizes.
+
+    The easiest way to create a TQBoxLayout is to use one of the
+    convenience classes, e.g. TQHBoxLayout (for \c Horizontal boxes) or
+    TQVBoxLayout (for \c Vertical boxes). You can also use the
+    TQBoxLayout constructor directly, specifying its direction as \c
+    LeftToRight, \c Down, \c RightToLeft or \c Up.
+
+    If the TQBoxLayout is not the top-level tqlayout (i.e. it is not
+    managing all of the widget's area and tqchildren), you must add it
+    to its tqparent tqlayout before you can do anything with it. The
+    normal way to add a tqlayout is by calling
+    parentLayout-\>addLayout().
+
+    Once you have done this, you can add boxes to the TQBoxLayout using
+    one of four functions:
+
+    \list
+    \i addWidget() to add a widget to the TQBoxLayout and set the
+    widget's stretch factor. (The stretch factor is along the row of
+    boxes.)
+
+    \i addSpacing() to create an empty box; this is one of the
+    functions you use to create nice and spacious dialogs. See below
+    for ways to set margins.
+
+    \i addStretch() to create an empty, stretchable box.
+
+    \i addLayout() to add a box containing another TQLayout to the row
+    and set that tqlayout's stretch factor.
+    \endlist
+
+    Use insertWidget(), insertSpacing(), insertStretch() or
+    insertLayout() to insert a box at a specified position in the
+    tqlayout.
+
+    TQBoxLayout also includes two margin widths:
+
+    \list
+    \i setMargin() sets the width of the outer border. This is the width
+       of the reserved space along each of the TQBoxLayout's four sides.
+    \i setSpacing() sets the width between neighboring boxes. (You
+       can use addSpacing() to get more space at a particular spot.)
+    \endlist
+
+    The margin defaults to 0. The spacing defaults to the same as the
+    margin width for a top-level tqlayout, or to the same as the tqparent
+    tqlayout. Both are parameters to the constructor.
+
+    To remove a widget from a tqlayout, call remove(). Calling
+    TQWidget::hide() on a widget also effectively removes the widget
+    from the tqlayout until TQWidget::show() is called.
+
+    You will almost always want to use TQVBoxLayout and TQHBoxLayout
+    rather than TQBoxLayout because of their convenient constructors.
