I read this tut: http://www.ar-ent.net/dar/arlib32/out/html/man/xul/index.html tbh I dont event know really many about it. But I am familiar with web-tech, CSS/JavaScript so the XUL-Stuff is easy for me to understand. The Problem is how to add this features to lazarus. > > > The 1st step would be to transform the lazarus-forms to XUL-Documents > > with proper css (component positioning, etc) > > Later on create the JavaScript stuff with XPCOM binding to the event > > handlers. > > Ehm, you know that there are more than a hundred classes and several > thousand properties which interact in complex ways, don't you? Yes I know ... This is one reason why I dont know where to start :) But I think the mozilla-projects and afaik the GNOME-Projekt shows that everything is possible with this kind of technology. So the main-part of this work is to replace the lcl-stuff which is in the app-binary as javascript-pendants. Because all gui-stuff is done in this language in xul. So you could see the app as the server and the XUl-gui-stuff as the client. > Maybe it is easier to start with an IDE extension to write > XUL/XPCOM apps? If you say it is easier I will try it this way. But I am not shure if this is possible, because the XUL-Approach is really different to all other GUI-Designs. And I am not a really experienced pascal-programmer tbh. Did too much web the last years :( thanks again for the tipps and I hope to be able to create someting. Hope I can contribute this to the project. Imo the idea is great expecially for the lazarus-projekt. > Since 0.9.29 the IDE can design non LCL gui components.
