If I understand it, then my solution is better, instead of using a language to help use a toolkit, I offer a language with tools that helps you develop GUI without the hassle of choosing the GUI toolkit, but to focus on your work, and think in DRY land ... If he choose Glade with GTK, he needs to start to think in grid like way of writing. If he chooses Qt with Qt-Develop, he will need to write a template, and then focus on understanding Qt I offer something different, different thinking, even know, without any knowledge of gui development, or even the programming language, a simple window, edit box, a button and a simple menu will take him less then 10 minutes. When he'll know to use it, it will take him 3-5 minutes tops. > > > With Lazarus, you program in a real programming language, and instead of > > using a middleware, you just cod your code, and the GUI is designed > without > > any line of code (unless you have to, or just want to do it like that). > > > > Are you implying that Vala is not a "real" programming language? > *"Vala* is an object-oriented <http://en.wikipedia.org/wiki/Object-oriented> programming language <http://en.wikipedia.org/wiki/Programming_language> with a self-hosting <http://en.wikipedia.org/wiki/Self-hosting> compiler<http://en.wikipedia.org/wiki/Compiler>that generates C <http://en.wikipedia.org/wiki/C_%28programming_language%29> code and uses the GObject <http://en.wikipedia.org/wiki/GObject> system. " http://en.wikipedia.org/wiki/Vala_%28programming_language%29 It's a "descriptive" language for C, that was built to help you develop GUI for GTK, and looks too much like C# (it's actually cool language C#, much better then Java, but that's off topic). > Regards, > > -- Shlomi Fish > > -- > ------------------------------------------ > Shlomi Fish http://www.shlomifish.org/ > > Electrical Engineering studies.
