Component for Diagrams ?
« on: November 22, 2012, 08:13:39 pm »
Hello,
one question. Do we have any component for drawing diagrams ?
Something similar to http://www.bluechillies.com/screenshot/51791.html but this one is only for Delphi and costs $3000.  :(
I don't need any advanced functionality, just a few shapes with description, connections and ability to load/save the designed diagram to disk.
Thanks.

EDIT:

I found this: http://www.delphiarea.com/products/delphi-components/simplegraph/ and I this link was also mentioned on mailing list as a candidate to porting. Did someone port it already ?

No idea, but I remember Avra (?) posting some state machine units that included a flow diagram that had connectors etc.

edit: see http://lazarus.freepascal.org/index.php/topic,17688.msg98008.html#msg98008

Perhaps you could adapt that.

I have an early alpha conversion of simplegraph for lazarus. So far it works on windows but I have renamed all the components and classes and removed a few like metafile support making it incompatible with the files that are generated from the original component set. It needs a lot of work (especially the printing which is based on metafiles ) and tests before I can share it but if you thing you can help with the conversion pm me.

the conversion is almost done, you can grab a copy from http://sourceforge.net/projects/evssimplegraph just make sure that you get everything from the code repo as the last download file have a file missing install it and use it.

At this point the only thing missing are printing and zooming in/out. The main idea for zooming is to implement that on the canvas classes of the component instead of the drawing classes them self.
As for printing I'm thinking to create a new class based on lazReport which given a list of drawing classes will be able to guide them to draw them self on the printing canvas or something along those lines.

The biggest problem at the moment is the testing and feed back, I have no idea if any one uses it or not and if yes what kind of problems they have. I have tested the components on GTK2, QT and WIN32 on a windows laptop and they seem to work acceptable for the time being. So feel free to try them out and report any problems you might have.
