XFig has the feature when you can 'open' groups. Then you can only see that group and edit the items singly, then later close it. We might want something somewhat similar, but maybe keeping the rest shown, marking open groups with dotted lines.

Isn't this wasteful in terms of memory, and the possiblity to modify once and have the change reflected in many insertions of the same group? Yes, it would be inferior in that way. Shapes don't get stored along with the dia file - they would be lost after saving the dxf as a dia file. Too bad. What would it involve to allow shapes to be stored in a dia file? Well, export to shape files does that already, so look that up. Also, the plugin menu of the toolbox allows loading modules, so you could have a 'dynamic' module that is reloaded every time a new shape is created. It's all in there. In fact, it would be useful overall to, say, have a 'Create Shape' menupoint (creating shapes dynamically from objects/groups). -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hårdgrim of Numenor I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it.| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

The short reason why, is that it's quite difficult to match the fonts available under X and the fonts available for printing. Portability of documents could be cited as another reason, since it would also be difficult to retrieve the font file, embed it into a dia file, and deliver the result on another machine while loading the diagram, to display or print it. This will probably last, until the usual chaos about fonts under X/PS-using desktops gets cleared, preferably with a solution which doesn't displease too many people... (once *that* is done, there will necessarily be some modifications to do to dia to take advantage of this, but compared with the unified font system itself, it'll probably be a snap to do). I disagree on this; I think we should get some better font support soon, even if it means that some documents will use replacement fonts when moved between machines. PostScript output can just have the font embedded. The problem of different font installations on different machines will not get fixed until there is some kind of font-server available for all that allows the document to specify and download fonts, and I don't see that happening any time soon. So if we can deal with the PostScript problems, we should be able to use whatever fonts are installed. We could even mark the fonts that are not PostScript compatible until such time as we can embed fonts into PostScript. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hårdgrim of Numenor I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it.| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

Groups and depths
Here's a problem with groups I just noticed: Grouping objects destroys their depths. When you create a group, it becomes a new object on top of the other objects, and the depth of the objects is ignored. Try this: Create three partially overlapping rectangles. Select the two lowest. Group them. They jump to the front. The objects in the group retain their relative depth, which is good. But the group object should not really have a depth of its own, rather the individual objects should be at their original depths. (And the Group/Ungroup operations should be idempotent inverses.) That, however, is tricky to do with the current implicit ordering. Is this something we should work on? Have anyone been bothered by this? I only noticed now that I look at groups for XFig. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hårdgrim of Numenor I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it.| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

Maybe creating a group shouldn't cause the objects to raise to the top of the stack, but grouped objects have always acted as one position in the depth stack in all the drawing software I have used. It depends on what a group is. It makes sense to say a group is a bunch of objects you manipulate together, in which case grouping shouldn't change their depth. But I know how hard it would be to change that in Dia, and I got a reasonable fix for XFig import (it puts it at the highest depth involved), so I don't think we should worry. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hårdgrim of Numenor I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it.| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

Interesting idea -- have drawRectangle, drawPolyline etc fall back to drawLine could be useful. But for arrowheads, it would require a very different approach, since the arrow information is still separate from the line information. i think this way it would be very easy, for example to write graphic format renderers.

I've narrowed the bug in xfig-import.c down to the handling of groups.
Everything else behaves nicely (well, doesn't crash at least), but whenever
there is a group involved, it crashes when the window gets closed.
This is the function I use to create a group. The items are all already
added to the layer, and work fine outside of groups. Am I missing
something crucial about groups?

No, CVS is for the developers. Having to point non-developers at the CVS version is IMHO a sign of lack of frequent enough releases. Most importantly, distributions and the like should never pick from CVS (see what happened to RedHat and gcc), but should be able to include a recent version. One of the things that makes a software project more dynamic is having making it more accesable through plugins and api's and documentation that mean people can pick it up and start hacking. I'd love to hack dia but my C isn't too hot, hence me doing automagic with Dia's XML using perl, having an API or a way to do perl plugins would make a huge difference. Let me put it this way: What do you want to be able to do from perl? Just create more objects, or more than that? finally thanks to the Dia developers and maintainers for doing things the right way - the XML file format is really useful - I am using it to create UML class diagrams in perl and now I'm parsing the xml into text/html documentation as well. I know of a bunch of other projects that taking the xml and doing cool stuff with it like dia2sql. Thanks for that go to Alex -- he did a very cool design right from the start, including the split between app, lib and objects. Anyone got any thoughts on Graphviz - it does automagic layout, don't know how much use or interest it would be to the Dia developers? I am planning to make my code work with both Dia and Graphviz.

IHMO the key question here is: Is the benefit on both sides ? Doing an official release does require some extra work which almost never falls into the fun category. Part of this work can be done by the users, who are willing to build from cvs. Doing an official release should also relieve us from a) having to point users at CVS for bugs that got fixed months ago, and thus b) having to help non-developers with getting the CVS version to compile.

I have a bunch of suggestions, but no showstoppers: For the Process object: Make it so that at least some of the text can be written directly into the diagram, rather than having to open the properties dialog each time. I'm not sure which would be more appropriate, as I don't know the EML. Could the first two tabs be combined into one, so there isn't so much dead space? Possibly with a labelled box around them. The Interfaces area doesn't really need the 'Move Up' and 'Move Down' buttons, as they do the same as when you click on the (scrollable) list. My first thought was that they rearranged the interfaces. The interface name entry box should understand Enter. For the three other objects: Use the standard properties code rather than putting GTK code into the objects. It's easier and more future-proof. For the Instantiation object: Make the segment with the arrows on it long enough to have the polyline go past the arrows. For everything: It would be nice if it understood at least the color selection. Many people have asked for UML with color, and it does color now, though not via the standard color selection:( None of these are showstoppers, just ideas for improvement.

I really don't see the point in targetting Gtk 2 until gtk2 is in (sort of) "release candidate" stage ; until major distributors ship libgtk2, I fear it's quite a waste of effort to work on two trees. Of course, if gtk2 is really that close already, then it makes sense to start the fork ASAP (but we should probably concentrate on a really clean 0.87, and a fully debugged .88 just afterwards, say, no more than two months after 0.87. I really think we don't have enough releases, and that we keep answering to FAQs in a "sorry, it's fixed in CVS for months but we haven't released anything" style.) Announcing a .88 just after .87 (while keeping the lid relatively closed on new features) would be an excellent way to test the new code (since .86) against real bugs, and would give translators a really nice time frame. I agree on this; aiming for a fast semi-stable release would give us time to then do the more serious improvements (better fonts, standard properties, etc) and work (slowly) towards a 1.0 release.

To set the default settings for new objects, double-click on the object icon, in this case either the text icon or the icon of whichever object you're using. Some objects don't allow setting the font, though, and some don't allow the defaults to be set. As for setting properties for a group of objects, you just need to Group Objects. Then you can set any properties (provided the objects use the standard property system). -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hrdgrim of Numenor "I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it."| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

If a diagram file is loaded with shapes that does not exist, one might want to browse the Sheet browser to pick a (matching) shape.

Another nice addition to this is to have a preview-shot of the shape that is selected (while browsing). I think the idea has merit, but I'll focus on the .087 release for now. Coming up with an interface for a browser would be a useful pastime, though. And what about (on-the-fly) creation of small icons of shapes (instead of the xpm-files) now we're at it. :) Well, saving as shape file gives an icon as well, but the quality is not very high.

This is especially noticeable with larger line widths, and I think it looks very ugly that way... Which is exactly why this isn't a 0.87 problem. We need to redesign how arrows are drawn completely. I was thinking of having the arrow be more of a part of the line, rather than something the object slaps on. Then the line-drawing code can do the arrowhead in the *right* way, and account for that in the line. But right now we need to look at what needs to be done for 0.87. I'm afraid that better font support would be as much work as better arrowheads, but I would really like the RLE stuff to get working.

The same way, I have thought of multiple shapes for an object. For example you could have a "computer" object and a choice of different shapes for different models.

Since we're not using the TAB key for anything, I think this would be useful. Also useful for things like UML Small Package or Component that contains several text fields already, but where you have to open Properties to edit them. Problem is that the object would require to get the keypresses, or somehow tell the system about the multiple text fields. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hrdgrim of Numenor "I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it."| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

Re: Event trace (sequence) diagrams
On Mon, 5 Mar 2001, Richard Nelson wrote: Hi all! New to Dia and this forum. Apologise if this one has already been asked. I have been using Together Enterprise and Rational Rose on previous projects and I am evaluating Dia for a new project. I would like to know to create event trace diagrams in Dia. So far I have been using lifeline, object and message tools but I would have expected the property diagogue for the object instances to list classes that have been defined. I should also have expected the properties dialogue of the message instances to allow the selection of the operations available in the object instance the message is directed at (as defined by the class it is representing). Dia doesn't know that UML diagrams are anything else than funny figures with a specific name. However, these examples show how some more interaction can improve the UI. I suppose the Object and Message instance could look through the list of objects to find such information, but we probably need a new piece of infrastructure for that. All this ensures that the class names and message names used in event trace diagrams are valid. That would be a good thing, wouldn't it? It would require, however, that when a a class changes, all instances of it have incoming messages checked for validity. I hold that all this should be optional -- many people use UML in an entirely informal manner, and would only feel restricted by such syntax-checking. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hrdgrim of Numenor "I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it."| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne
Re: Defaults dialogs

I see three problems that need to be resolved: 1) Should the defaults be object-specific or name-based? I'd say name-based, but then we get the possibility of accidentally transferring defaults between sheets. Is that going to be a problem? 2) More serious: Each property should have a default value. If the defaults are name-based, there can only be one default value for any property of that name, which might not please everyone. In most cases, we probably want per property rather than per object (eg. at the moment, default colours, line styles, line widths and fonts are shared between all types). I am sure there are some cases where having things per object is useful as well. Maybe we could have it be the combination of the name and the default value that identifies a grouping? And maybe I should check how many cases there are of this before I do large nasty designs. 3) How does an object specify the default value? I'd like to add it to the PropDescription struct, but that would break binary compatability. Adding another struct for this would be plain silly. Well, at the moment PropDescription structs are static, whereas the default values for properties are mutable in dia. Is this feature worth preserving? How do we handle multiple objects types which should share a default, yet have separate (identical) PropDescription structs? What do you mean, the default values for properties are mutable? The only default values currently used (except for the standard properties) are hardcoded. With the glib 2.0 GObject properties, there is a g_param_value_set_default() function that can be used to modify the default for a GParamSpec, so this sort of thing will be possible when we move over to gtk 2.0 (and I think you can share a single GParamSpec between multiple object types on different branches of the type tree, which would handle the shared defaults problem). That does sound good. I'm looking forward to it. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hrdgrim of Numenor "I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it."| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

I don't think it is safe to assume that properties of the same name on different object types are always going to be the same, and hence use the same default. However, in a lot of cases (the shared ones I mentioned above), it is. On the other hand, you would probably want all object types in one sheet share similarly-named properties. Maybe we could allow the definition of a 'defaults group' within which defaults are shared? Either per-object type or per-property. Or maybe just have each sheet share properties. Things like the "draw background" or "corner rounding" for the standard box have defaults that can be changed from the defaults dialog. Hence, they are mutable during the run of the program. All the other data in the PropDescription struct (name, description, prop type, etc) is fixed. I see what you mean. I don't see much reason to change this. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hrdgrim of Numenor "I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it."| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

Finally, there's the case of polylines and zigzags (same for beziers, I think), where the arrow head finds itself with a default orientation (0) when the last segment has a zero length (I'd vote for making the arrow disappear in that case, rather than extend the bounding box). Remember that as long as we can't query objects for orthogonality, the current arrow behaviour does allow one to get around the default orientations.

More UML fixes
So I've fixed a couple more of the UML objects to use proper properties. I don't suppose the properties code supports something like what the Association object does, of grouping properties and placing them side by side? Not to mention what the Class object does... Also, the Branch object, which only has the ELEMENT_COMMON_PROPERTIES, shows up a property dialog with nothing in it, rather than 'This object has no properties'. UML users, please hit on the updated objects and see how they hold up. They should all do font stuff and bounding boxes nicely now (except for a funny late update in Component that I haven't figured out). -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hrdgrim of Numenor "I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it."| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

Creating objects for import
I'm working on XFig import (finally!), and while the simple objects like boxes and ellipses are easy enough, the polygon is not. If I were to only use the external interface to Standard - Polygon, I can't add extra corners. If I also use the functions from the middle mouse menu, I can add corners, but with little control over how the corners are ordered (since it picks the closest segment always). So I'm this close to adding a new standard function, basic_create(Point[], int), that will create the object directly rather than using handles. The function takes an array of points that the object is created from, and the number of points in the array. Exactly how the points are use is defined by the object.

Shouldn't diagram_modified_exists consider a diagram unmodified if it has no undo history? Yes. Better: why wouldn't we alow undo past saving ? Emacs does this and sometimes this helps. This involve to have a save marker in the undo stack and not flushing the undo stack at save. We don't flush the undo stack at save. But a save marker in the undo stack would mean that we wouldn't need the diagram-modified field anymore. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hrdgrim of Numenor "I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it."| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne

The problem I'm having is to find a way to publish my network graphs on our ethernet and... I can't. how can I save my graph into a png or jpg file ? can it be done ? Yes, select File/Export on the image menu. Then pick your file format of preference. I think I'm just quietly gonna combine Save As and Export to avoid these problems in the future. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause) | Hrdgrim of Numenor "I do not agree with a word that you say, but I| Retainer of Sir Kegg will defend to the death your right to say it."| of Westfield --Evelyn Beatrice Hall paraphrasing Voltaire | Chaos Berserker of Khorne
