I am not sure if this has been reported before (Google did not find it).

Looks like an oversight in the original patch (and for the 7 years since 
than ;))

The Activity icon on the UML sheet does not have a center anchor.  The
State icon does.

There are some more inconsistencies between different UML objects - like 
for example not every object supports stereotype. It should be relatively 
easy to add these.


Patches accepted,

Hi. How about to use a cairo graphic to render primitives?
Probably I'm misunderstanding something in your request, because there is a 
cairo renderer available with Dia since 2004 - see:

http://git.gnome.org/browse/dia/log/plug-ins/cairo?ofs=100


So, I have some free time, and I can try do something by myself, if you say
me what files contains render system.


The basis is the DiaRenderer interface:
http://git.gnome.org/browse/dia/tree/lib/diarenderer.h

Most of the renderers are implmented as plug-ins, see e.g. plug-ins/cairo

Connect two lines?

[Ohto Nordberg]

I can connect a line to a box, but not line to line. I am trying to draw
graphs like this:

I would like to draw graphs like that easily, not sure if Dia can do that?

Thank you,
Ohto Nordberg

Re: Connect two lines?

[Michael Ross]

You cannot connect lines directly. But you can use a scaled down connection
point between the lines.

Alternately, you can use a bezier line which is completely adaptable  - you
can even make corners by reducing the slope grips (sorry I do not
know the proper name for these).

Ohto,

I think you can if you make connector points and draw lines between
them. I think such point do not exist yet but creating them should be
easy.
