Re: [TM4J-users] Touchgrahprenderer promblem

[Christoph F. <cf...@fo...>]

Hi Wang

I would say it's a bug. There is some functionality that tries to assert
that no more nodes are drawn than a user could actually distinguish and
navigate but 
a. it does not work as expected
b. there is no real strategy how to deal with the case, that a node has
more relations that could actually be drawn.

If you want to investigate by yourself, you find the code block in
charge beginning at line 160 of org.tm4j.tmnav.renderer.tg.
TMOTouchgraphNode.

Otherwise you can enter a bug report. This would assert that I don't
miss the bug, when I will be able to work on tmnav again. Unfortunately
this won't be before mid of june.

Hope that helps a bit
