Member Function Documentation

virtual void CHandleShape::DrawControlPointPath ( GraphicsData *  gd, int32  flags  )

virtual

Draw the path based on item's control points.

Parameters

gd	the graphics context used for drawing.
flags	default as kNoFlags and serves as a drawing flag.

Returns

void.

Implements IHandleShape.

virtual void CHandleShape::DrawHandleShape ( GraphicsData *  gd, IConcreteSelection *  concreteSelection, int32  flags  )

virtual

Draw the selection handle of item.

Parameters

gd	the graphics context used for drawing.
concretSelection	the selection boss.
flags	default as kNoFlags and serves as a drawing flag.

Returns

void.

Implements IHandleShape.

virtual void CHandleShape::GetControlPointPathOutlineInfo ( IOutlineInfo *  iOutlineInfo )

virtual

Get the path information of item's control points.

Parameters

iOutlineInfo

the out parameter with the control point path.

Returns

void.

Implements IHandleShape.

Reimplemented in PathHandleShape.

virtual PMRect CHandleShape::GetPaintedHandleBounds ( const PMMatrix &  pbtoview )

virtual

Get the bounding box by computing it in pasteboard coords and then transforming it by pbtoview.

Parameters

pbtoview

the matrix to transform the bounds based on pasteboard coordinates.

Returns

PMRect the bounds for painting(redrawing).

Implements IHandleShape.

Reimplemented in BscShpPathHandleShape.

virtual bool16 CHandleShape::HitTest ( GraphicsData *  gd, const PMRect &  r, PointSelector *  handleIndex, bool16  bDragging  )

virtual

Check if a particular handle of the item has been hit or not within the specified area.

Parameters

gd	the graphics context used for hit testing.
r	the area for checking hit test.
handleIndex	the index of selection handle.
bDragging	the flag indicating if hit test if during dragging or not.

Returns

bool16 kTrue if it hits, otherwise kFalse.

Implements IHandleShape.

virtual bool16 CHandleShape::HitTestControlPointPath ( GraphicsData *  gd, const PMRect &  r  )

virtual

Check if the control point path has been hit or not.

Parameters

gd	the graphics context used for hit testing.
r	the area for checking hit test.

Returns

bool16 kTrue if it hits, otherwise kFalse.

Implements IHandleShape.

virtual void CHandleShape::Inval ( GraphicsData *  gd, ClassID  reasonForInval, int32  flags  )

virtual

Invalidate the appropriate region of the object in the graphics context.

Parameters

gd	the graphics context used for invalidation.
reasonForInval	the ClassID defined for inval reason for handling different inval cases.
flags	default as kNoFlags and serves as a drawing flag.

Returns

void.

Implements IHandleShape.

virtual ITip* CHandleShape::QueryTip ( const PointSelector *  handleIndex )

virtual

Query for any tip implemented on the shape. If there is any tip on the shape then the ITip interfacePtr will be returned else nil is returned in the default implementation

Parameters

handleIndex

the index of the handle for the shape

Returns

ITip* the result tip

Implements IHandleShape.

virtual ITracker* CHandleShape::QueryTracker ( IControlView *  layView, const PBPMPoint &  where, int32  selectionMode, const PointSelector &  index  )

virtual

Query the tracker based on the given mouse position, hit test mode and selection handle index.

Parameters

layView	the active layout view where mouse is on.
where	the mouse position based on pasteboard coordinate.
selectionMode	the hit test flags.
index	specifies the index of selection handle.

Returns

ITracker* the result tracker and caller should deference it.

Implements IHandleShape.

Reimplemented in PathHandleShape.
