I am a Delphi Developer from Delphi 1. And before Clipper/DBase/Informix 4GL developer (I have used ORACLE 1.0 for PC, 1986).
Please ask yourself because DevExpress is used from Delphi developers, like other 3rd components...
It's easy. Because we can develope FASTER with a lot of POWERFUL options for the customers. We produce A LOT of applications... professional, not one for test or for play... we have no time for write (existing) components.
I ask the implementation of ExtJs features that already exists, like virtual scroll, etc.. for obtain perfect result.
CGdevtools for Intraweb, for example, exists for add features to Intraweb standard....
Please note, I also started 1986, since 1990 with Unix/PC/Ingres and we develop also since Delphi 1 for the financal market, key projects for customers who manage up to over 1.000.000.000 €. So, not only you, also others did not get the time for "test and play".
And sorry, "developing components" is not "playing" - it's a chance to be better and win in the market. BTW, to extend components by existing - often not more than a few lines of code.
To my mind the thread should not drift down to a level "oh oh, 800 €, 1000 €, how expensive ! we can't pay" and on the other side "we will not be able to use unigui if not all features for our projects can be done by simple: click,click".
All of us will be able to save much money in development and Farshad shall be the only one to do the work for, providing a complete development tool with all features ? For "perfect results" - and that in advance ? Still not earning money ? - Please be patient; permanently ask for new features - that's really not fair to him (Sorry).
Isn't it time for an official release of unigui without more features, but "as it is" ?
