Constructor & Destructor Documentation

ItemDelegate::ItemDelegate ( QObject *  parent = 0  )  [explicit]

Constructor. Creates an ItemDelegate with parent parent

Definition at line 101 of file kdganttitemdelegate.cpp.

ItemDelegate::~ItemDelegate (  )  [virtual]

Destructor

Definition at line 107 of file kdganttitemdelegate.cpp.

Member Function Documentation

QRectF ItemDelegate::constraintBoundingRect ( const QPointF &  start,
const QPointF &  end,
const Constraint &  constraint 
) const [virtual]

Returns:
The bounding rectangle for the graphics used to represent a constraint between points start and end (typically an arrow)

Definition at line 343 of file kdganttitemdelegate.cpp.

QBrush ItemDelegate::defaultBrush ( ItemType  type  )  const

Returns:
The default brush for item type type
Todo:
Move this to GraphicsView to make delegate stateless.

Definition at line 129 of file kdganttitemdelegate.cpp.

QPen ItemDelegate::defaultPen ( ItemType  type  )  const

Returns:
The default pen for item type type
Todo:
Move this to GraphicsView to make delegate stateless.

Definition at line 149 of file kdganttitemdelegate.cpp.

QPolygonF ItemDelegate::finishFinishArrow ( const QPointF &  start,
const QPointF &  end 
) const [protected]

Definition at line 500 of file kdganttitemdelegate.cpp.

QPolygonF ItemDelegate::finishFinishLine ( const QPointF &  start,
const QPointF &  end 
) const [protected]

Definition at line 478 of file kdganttitemdelegate.cpp.

QPolygonF ItemDelegate::finishStartArrow ( const QPointF &  start,
const QPointF &  end 
) const [protected]

Definition at line 442 of file kdganttitemdelegate.cpp.

QPolygonF ItemDelegate::finishStartLine ( const QPointF &  start,
const QPointF &  end 
) const [protected]

Definition at line 420 of file kdganttitemdelegate.cpp.

ItemDelegate::InteractionState ItemDelegate::interactionStateFor ( const QPointF &  pos,
const StyleOptionGanttItem &  opt,
const QModelIndex &  idx 
) const [virtual]

Returns:
The interaction state for position pos on item idx when rendered with options opt. This is used to tell the view about how the item should react to mouse click/drag.
Override to implement new items or interactions.

Definition at line 197 of file kdganttitemdelegate.cpp.

Span ItemDelegate::itemBoundingSpan ( const StyleOptionGanttItem &  opt,
const QModelIndex &  idx 
) const [virtual]

Returns:
The bounding Span for the item identified by idx when rendered with options opt. This is often the same as the span given by the AbstractGrid for idx, but it might be larger in case there are additional texts or decorations on the item.
Override this to implement new itemtypes or to change the look of the existing ones.

Definition at line 162 of file kdganttitemdelegate.cpp.

void ItemDelegate::paintConstraintItem ( QPainter *  painter,
const QStyleOptionGraphicsItem &  opt,
const QPointF &  start,
const QPointF &  end,
const Constraint &  constraint 
) [virtual]

Paints the constraint between points start and end using painter and opt.

Todo:
Review opt's type

Definition at line 371 of file kdganttitemdelegate.cpp.

const QPointF &  start,
const QPointF &  end,
const Constraint &  constraint 
) [protected]

Definition at line 393 of file kdganttitemdelegate.cpp.

void ItemDelegate::paintGanttItem ( QPainter *  painter,
const StyleOptionGanttItem &  opt,
const QModelIndex &  idx 
) [virtual]

Paints the gantt item idx using painter and opt

Definition at line 222 of file kdganttitemdelegate.cpp.

void ItemDelegate::paintStartFinishConstraint ( QPainter *  p,
const QStyleOptionGraphicsItem &  opt,
const QPointF &  start,
const QPointF &  end,

const QStyleOptionGraphicsItem &  opt,
const QPointF &  start,
const QPointF &  end,
const Constraint &  constraint 
) [protected]

Definition at line 509 of file kdganttitemdelegate.cpp.

void ItemDelegate::setDefaultBrush ( ItemType  type,
const QBrush &  brush 
)

Sets the default brush used for items of type type to brush. The default brush is used in the case when the model does not provide an explicit brush.

Todo:
Move this to GraphicsView to make delegate stateless.

Definition at line 120 of file kdganttitemdelegate.cpp.

void ItemDelegate::setDefaultPen ( ItemType  type,
const QPen &  pen 
)

Sets the default pen used for items of type type to pen. The default pen is used in the case when the model does not provide an explicit pen.

Todo:
Move this to GraphicsView to make delegate stateless.
