DoResize Method (GoStroke)

In This Topic

When the resize handles are at each point of the stroke, the user's dragging of a resize handle should just change that point in the stroke.

Syntax

public override void DoResize( 
   GoView view,
   RectangleF origRect,
   PointF newPoint,
   int whichHandle,
   GoInputState evttype,
   SizeF min,
   SizeF max
)

Parameters

view

the GoView whose GoToolResizing is calling this method

origRect

the original Bounds of the object, but probably not useful for strokes

newPoint

the PointF, in document coordinates, to which the resize handle is being dragged

whichHandle

The IGoHandle.IGoHandle.HandleID of the handle being dragged; for strokes this usually means that a value greater or equal to GoObject.LastHandle is actually the index of a point in the stroke, when one subtracts GoObject.LastHandle.

evttype

when called from GoToolResizing.Start
when called from GoToolResizing.DoMouseMove
when called from GoToolResizing.DoMouseUp
when the GoToolResizing.DoCancelMouse

min

the value of GoToolResizing.GoToolResizing.MinimumSize, but probably not useful for strokes

max

the value of GoToolResizing.GoToolResizing.MaximumSize, but probably not useful for strokes

Remarks

When ResizesRealtime is true, this method always calls SetPoint. Otherwise it only calls SetPoint when the is GoInputState.Finish or GoInputState.Cancel.
