I can describe why this is happening, but I still can't replicate it on our versions of ubuntu, so I'm not sure how best to provide a fix. When given a graph, dotty calls dot -Txdot to get the necessary rendering information. By default, fontname is set to "Times-Roman". When using an X11 interface, dotty maps this to '-*-times- medium-r-*--%d-*-*-*-*-*-*-1', where the %d will be replaced with the desired font size. When text is written, dotty calls XLoadQueryFont (display,fontname). If the call fails with the requested font size, dotty increments and decrements the size to see if a nearby font can be found. If this fails, dotty draws a tiny box for the text.
So on the systems having problems, the call XLoadQueryFont (display ,"-*-times-medium-r-*--14-*-*-*-*-*-*-1") is failing. So, why is the match failing on these systems? As a workaround, the mapping I mentioned is defined in the text file share/graphviz/lefty/dotty.lefty, so a user could fix Times-Roman to map to an available X11 font. One could also set a specific fontname attribute in the graph. This problem with this is that names that XLoadQueryFont will accept won't be handled well by the font resolution in pango. For me, pango maps the request for times-medium to a sans serif font. As long as the font metrics are not too far off, this probably won't matter too much. But why is dotty still being used? If one just wants a single command for drawing and displaying a graph, why not use dot -Tx11 ? For the record, the right-button menus work fine for me on Ubuntu 12.04 with Graphviz 2.36. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016777 Title: dotty missing labels and context menu is broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/graphviz/+bug/1016777/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
