Problems with CreationTool [message #84082]

Hello

I wrote a 'LineCreationTool' extending CreationTool. Also I extended the
handleButtonUp- and handleButtonDown -method to set start- and endpoint. But
the problem is the getLocation- methode from AbstactTool. When I scroll down
(the zero-point is outside the drawing area) and draw a line, getLocation
gives back a wrong point. It is the right point relative to the edge of the
drawing area but not right relative to the zero point.

Is there another possibility to get the correct position?

locations are always absolute in tools, meaning relative to the Canvas, not
the scrolled diagram.

To get the correct position, the target of the line creation (probably the
diagram itself), should take the point, and call:
Figure.tranlsateToRelative(point);

Make sure you don't modify a Point you don't own.
