Detailed Description

Class used to render gantt items in a KGantt::GraphicsView.

Definition at line 28 of file kganttitemdelegate.h.

Constructor & Destructor Documentation

ItemDelegate::ItemDelegate ( QObject parent = nullptr)
explicit

Constructor. Creates an ItemDelegate with parent parent

Definition at line 97 of file kganttitemdelegate.cpp.

ItemDelegate::~ItemDelegate ( )
override

Destructor

Definition at line 103 of file kganttitemdelegate.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 344 of file kganttitemdelegate.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 117 of file kganttitemdelegate.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 129 of file kganttitemdelegate.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 183 of file kganttitemdelegate.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 150 of file kganttitemdelegate.cpp.

void ItemDelegate::paintConstraintItem ( QPainter p,
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 366 of file kganttitemdelegate.cpp.

void ItemDelegate::paintGanttItem ( QPainter p,
const StyleOptionGanttItem opt,
const QModelIndex idx 
)
virtual

Paints the gantt item idx using painter and opt

Definition at line 217 of file kganttitemdelegate.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 111 of file kganttitemdelegate.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.

Definition at line 123 of file kganttitemdelegate.cpp.

QString ItemDelegate::toolTip ( const QModelIndex idx) const
virtual
Returns
The tooltip for index idx

Definition at line 135 of file kganttitemdelegate.cpp.
