[Netron-graphlib] Bugs, GraphML and request

[Martin C. <mar...@ei...>]

Hi Francois,

I've come across a few bugs in the current code. I'll list them here so you
have a record. I may fix them myself time permitting.

1. Using the scrollbars to scroll to the left or to scroll up on a big graph
leaves lines on the graphcontrol. This lines disappear when you move the
mouse over the graphcontrol
2. When using CTL+SHIFT+Right mouse button to Zoom Out the popup menu for
the control pops up.
3. Dragging a connection from one Connector to another can be a bit tricky
sometimes. Grabbing the from connector is fine but getting the hit on the to
Connector is problematic. I think the root of the problem is that the
crosshair cursor is offset from the line end and therefore a hit event is
not raised when the crosshair moves over the connector. Maybe the problem
can be solved by changing the cursor. (This was picked up by people using
this for the first time here)
4. Trying to resize a shape that has connectors defined has been causing me
problems too.

GraphML support - argghhh ;-) Tricky thing to handle. I've got some basic
stuff put together, but its not generic enough. I hope to have something
done for next week Wed/Thurs.	

I now have a need for adding connectors to connections. Is this something
you would consider adding as standard? 

Regards,

Martin
