+  \class KDGanttViewTaskItem KDGanttViewTaskItem.h
+
+  This class represents calendar items in Gantt charts.
+
+  A calendar item in a Gantt chart has no start/end shape,
+  it is displayed as a rectangle.
+  You can set the colors as usual, where only the first argument of
+  setColors( col, col, col )
+  is important.
+  If the start time is equal to the end time, the item is displayed as
+  ø, showing that there is no time interval set.
+
+  For a KDGanttViewTaskItem, the text, setted by \a setText(),
+  is shown in the item itself and the text is truncated automatically
+  to fit in the item.
+  For all other item types, the text is shown right of the item.
