/*!
Paints a Gantt view on a TQPainter.
You can specify, whether the list view, the time line, or the legend
is painted.
All combinations of these three widgets are allowed.
Returns the size of the painted area.
Paints the list view in the top-left corner, the time line to the
right of the list view, and the legend below the list view.
If called with \a p = 0, nothing is painted and only
the size of the painted area is computed.
This is useful for determining only the painted area and setting
the scale of the painter, before calling this method with a painter.
In order to get the output fitted to your paper and your printer,
call first
TQSize size = drawContents( 0, printListView, printTimeLine, printLegend );
//then compute the scale
dx = paper.width() / size.width();
dy = paper.height() / size.height();
//then make float scale to fit the width or height of the paper
if ( dx < dy )
scale = dx;
else
scale = dy;
// then set the scale
p.scale( scale, scale );
// and now call drawContents with painter p

This virtual method specifies whether a drop event may be accepted or not.
To accept a drop event, call e->accept( true );
To not accept a drop event, call e->accept( false );
This method does nothing but allowing to execute the internal
drag move event handling.
In order to specify user-defined drop acceptance for particular
items, subclass KDGanttView and reimplement this method.
\param e The TQDragMoveEvent
Note: e->source() is a pointer to the KDGanttView, the drag started from.
I.e. if e->source() == this, this drag is an internal drag.
draggedItem 0, if this is a drag operation from another KDGanttView instance.
If this drag is an internal drag (i.e., within the KDGanttView),
this parameter points to the dragged item.
itemBelowMouse a pointer to the item below the dragged item
(i.e., below the mouse).
If you accept the drop, the dragged item will be inserted
in the KDGanttView as a child of this item.
The value is 0 if there is no item below the dragged item,
and the dragged item will be inserted as a root item.
\return false, when the internal drag move event handling should be executed
true, when the internal drag move event handling should not
be executed; usually you should return true,
if you have called e->accept( true ) before.
