\class KDGanttViewTaskItem KDGanttViewTaskItem.h
|
|
|
|
This class represents calendar items in Gantt charts.
|
|
|
|
A calendar item in a Gantt chart has no start/end tqshape,
|
|
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.
