I'm still hoping to port QtQuran to the Zaurus rather than try to re-invent the wheel. However, libquran is segfaulting on me and when I had a look at the code I realised that the combination of C and the callback-type of XML parser (libexpat) made the whole thing very difficult for me to understand. Because I am aiming to do other projects using Quran data, I decided to see if I could by-pass all the XML stuff for use in any python programs I am writing in terms of islamic/arabic software. As an aside, my personal opinion is that XML is great for transporting data between applications, but is poor for the internal representation of data in the vast majority of applications. I prefer to have a simple native object-oriented view of the data in my apps, and import and export to XML as and when it's required. Adopting that principle I imported the Quran XML into a sqlite database and now I find that using the data is very very simple from python by using SQL. Searches become very easy and quick etc. To be honest, for those using sqlite, libquran becomes redundant (i.e. unnecessary) for the looking-up and searching of aayaat. Having said that, not everyone will want to use SQL and libquran will be ideal for them. So anyway I knocked together a quick quran browsing app in python and tried it on the zaurus. I found that there is a lot to be done in terms of displaying quranic arabic and tashkeel in Qt 2.3, which will need to be done whether we are using QtQuran or anything else. The work M Yousif is doing, I believe, is primarily on the rendering of the quranic arabic in modern environments. He is using OpenType as the font format and I think this is probably the best way forward. Unfortunately, on Qt 2.3, this format is not supported. Therefore in the embedded environment I am currently of the opinion that the best way forward is to either: A - Don't ty to display tajweed marks etc, just display the basic quran text in an easy-to-read font with Harakaat. or B - Bypass the native font technology and manually place each glyph on the canvas. This is a lot easier than it sounds, and allows the developer total control over the look of the final result. As a final note, I should say that even though I am comfortable with C++, developing apps is so much faster with python. Just a quick advert there :-) wassalaam abdulhaq _______________________________________________ Developer mailing list [email protected] http://lists.arabeyes.org/mailman/listinfo/developer
