Constructor & Destructor Documentation

ItemDelegate::ItemDelegate ( QObject *  parent = 0 )

explicit

Constructor. Creates an ItemDelegate with parent parent

Definition at line 102 of file kdganttitemdelegate.cpp.

ItemDelegate::~ItemDelegate ( )

virtual

Destructor

Definition at line 108 of file kdganttitemdelegate.cpp.

Member Function Documentation

QRectF ItemDelegate::constraintBoundingRect ( const QPointF &  start, const QPointF &  end  ) 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 357 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 130 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 150 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 200 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 163 of file kdganttitemdelegate.cpp.

void ItemDelegate::paintConstraintItem ( QPainter *  painter, const QStyleOptionGraphicsItem &  opt, const QPointF &  start, const QPointF &  end, const QPen &  pen  )

virtual

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

Todo:

Review opt's type

Definition at line 386 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 225 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 121 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.
