◆ print() [1/4]

void GraphicsScene::print ( QPainter *  painter,
const QRectF &  _targetRect = 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.

Definition at line 693 of file kdganttgraphicsscene.cpp.

◆ print() [2/4]

void GraphicsScene::print ( QPainter *  painter,
qreal  start,
qreal  end,
const QRectF &  _targetRect = 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.

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.

Definition at line 713 of file kdganttgraphicsscene.cpp.

◆ print() [3/4]

void GraphicsScene::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.

Definition at line 649 of file kdganttgraphicsscene.cpp.

◆ print() [4/4]

void GraphicsScene::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.
