 Mmm, could be nice. Maybe ctrl-click or something.

 Size:ing is a more difficult thing in Dia. A lot of objects control
 and limit their size, all the user can do is move movable handles.
 Some (like the uml class) calculates size based ONLY on the objects
 properties.

 Yeah, but once they are done all objects can easily use them.

 Well, i rather though it would be just a pop-up selection of arrow
 types, and then the line objects has two of these, one for each end.

 Yes of course. thats why you'd have to add it to an object method.
 element.c is a base-class for box-like objects and connection.c is a
 base-class for line-like objects. Many objects derive from these to
 save you from typing a lot of stuff.

 Ooops i missunderstood. Sorry.

 Try it out.

 Hmm, i don't see this as exactly the work dia is most usable for, but
 i see your point.

 I fixed it in cvs. Did you mean that? I just commented out the
 tool_reset() call.

 Yeah, this is easy. Maybe should be added as an boolean flag in the
 standard box object.

 Yeah, i'm not good at file-formats. pdf is ~ postscript. I got a wish
 for exporting to WMF (windows meta files) yesterday.

 Well, i tend to make rather stable stuff. Dunno why.
