Detailed Description

This widget that consists of a QTreeView and a GraphicsView.

This is the easy to use, complete gantt chart widget. It consists of a QTreeView on the left and a KDGantt::GraphicsView on the right separated by a QSplitter. The two views share the same model.

void View::print ( QPrinter *  printer,
bool  drawRowLabels = true,
bool  drawColumnLabels = true 
)

Print the Gantt chart using printer. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.

This version of print() will print multiple pages.

void View::print ( QPrinter *  printer,
qreal  start,
qreal  end,
bool  drawRowLabels = true,
bool  drawColumnLabels = true 
)

Print part of the Gantt chart from start to end using printer. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.

This version of print() will print multiple pages.

To print a certain range of a chart with a DateTimeGrid, use qreal DateTimeGrid::mapFromDateTime( const QDateTime& dt) const to figure out the values for start and end.

void View::print ( QPainter *  painter,
const QRectF &  target = QRectF(),
bool  drawRowLabels = true,
bool  drawColumnLabels = true 
)

Render the GanttView inside the rectangle target using the painter painter. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.

void View::setGraphicsView ( GraphicsView gv)

Set the GraphicsView to be used for this View. It only makes sense to call this if you need to subclass GraphicsView.

NOTE: Only call this right after creating the View, before setting a model or any other attributes.

void View::setGrid ( AbstractGrid grid)
slot

Sets the AbstractGrid for this view. The grid is an object that controls how QModelIndexes are mapped to and from the view and how the background and header is rendered.

void View::setRowController ( AbstractRowController ctrl)

Sets ctrl to be the rowcontroller used by this View. The default rowcontroller is owned by KDGantt::View and is suitable for the default treeview in the left part of the view. You probably only want to change this if you replace the treeview.
