Member Enumeration Documentation

◆ InteractionState

enum KGantt::ItemDelegate::InteractionState

Definition at line 38 of file kganttitemdelegate.h.

Constructor & Destructor Documentation

◆ ItemDelegate()

ItemDelegate::ItemDelegate ( QObject * parent = nullptr )

explicit

Constructor. Creates an ItemDelegate with parent parent

Definition at line 95 of file kganttitemdelegate.cpp.

◆ ~ItemDelegate()

ItemDelegate::~ItemDelegate ( )

override

Destructor

Definition at line 101 of file kganttitemdelegate.cpp.

Member Function Documentation

◆ constraintBoundingRect()

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 342 of file kganttitemdelegate.cpp.

◆ defaultBrush()

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 115 of file kganttitemdelegate.cpp.

◆ defaultPen()

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 127 of file kganttitemdelegate.cpp.

		const QPointF &	end ) const

protected

Definition at line 443 of file kganttitemdelegate.cpp.

◆ finishStartArrow()

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

protected

Definition at line 419 of file kganttitemdelegate.cpp.

◆ finishStartLine()

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

protected

Definition at line 397 of file kganttitemdelegate.cpp.

◆ interactionStateFor()

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 181 of file kganttitemdelegate.cpp.

◆ itemBoundingSpan()

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 148 of file kganttitemdelegate.cpp.

◆ paintConstraintItem()

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

virtual

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

Todo: Review opt's type

Definition at line 364 of file kganttitemdelegate.cpp.

protected

Definition at line 476 of file kganttitemdelegate.cpp.

◆ setDefaultBrush()

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 109 of file kganttitemdelegate.cpp.
