I’d like to develop an application with a complex GUI (combobox with animation, charts with spline, transparent layers, …). I have good experience with C# 2.0 and I’m studying WPF, but I read that, unfortunately, there is no plan to port WPF to Mono.
If I stick with C# and create custom GUI controls using OpenGL (via OpenTK), I feel it will be a hard work (integration with GTK#, debugging, hard to use to design forms).
I can use Java (with JOGL), but I’m not very skilled with it, and I don’t know about performance issues.
Last option is C++, but I have to do a big revision (years since last time I used it), and I find it hard to develop GUI and portable applications in C++. (Maybe I’m wrong! Still, I’m quite afraid to develop such complex application with this language.)
What is your advice? Had I better choose C# + OpenTK, Java + JOGL, or return to C++?
I would go with Qt. Take a look at http://qt.nokia.com/products/ . If you are afraid of C++ (but there is no reason to be afraid of it), you can try with Java Swing. I think that those are the best options to go with multi platform desktop GUI development.
I would suggest Mono and GTK#. Developing apps with .Net is far more effective than doing it in C++ vanilla. Sure, you have to stick with C# 3.0 and .Net 2.0 (some features from 3.5 is implemented, like LINQ). But it still gives you a lot more than C++ with, for instance QT, would give you.
Go C# for productivity. Nothing against C++ but it's a bit verbose. As for the GUI library, I think WinForms used to work on Mono. Alternatively, GTK#.
I would not suggest using wpf for it is a platform dependant platform. Silverlight might be a better option.
But if you are developing a web application, jquery would be a nice option you also might consider adobe flex and adobe air; http://www.adobe.com/products/air/
Does multi-platform have to include iDevices? Can it be on the web? Those are 2 questions you have to answer first.
If you can live without iPad/iPhone suppport, then Flex/Flash/Air is good option for highly graphical things. It is multi-platform for sure and easily integrates to the web. Probably your best option for this case with the limited details given.
Qt could work for you as well, although I can't say for sure if it's graphic library will make it easy. I've personally never worked with it, so other would have to answer that. But since it is in C++, you could use other libraries as well.
Java Swing sounds rough to me for this complex of a GUI. Making some basic stuff isn't too bad, but if you are expecting an experience like with C# I think you will be frustrated. Just a personal opinion of course.
Lastly, if it can be a web app, why not stick with C# and Silverlight? A .NET solution may work well for you since you are already learning it.
Silverlight runs on Windows/Mac/Linux and some handhelds, and is being ported to more handhelds. I believe Silverlight will ultimately be ported to every popular device.
Silverlight is:
- Much, much more powerful than Flex/Flash/Air.
- Much, much more powerful than Qt.
- Ridiculously more powerful than GTK+ or GTK#.
- Ridiculously more powerful than JOGL.
Silverlight has all of the features you have requested.
Silverlight works very well with C#, which is a much more productive language to work in than C++.
Silverlight is basically a very large subset of WPF, so if you already know WPF, you already know Silverlight.
Unless you absolutely require iPhone/iPad support I think the decision is perfectly obvious.
See this comparison of WPF and Cocoa to get some feeling of how WPF/Silverlight compares with the likes of Qt, Flash/Flex/Air, and GTK#, all of which use a primitive WinForms-like object model similar to the one used by Cocoa.
At my day job (a well-known microprocessor company) we develop complex engineering apps with Java, Eclipse RCP, and Java OpenGL. Performance is good -- we can easily get many millions of polygons/second and up to 100 frames/second. The SWT widgets in Eclipse are fast enough where we haven't had to render any custom controls with JOGL.
I've got a set of tutorials that shows how to get started with this kind of programming. The series starts with http://wadeawalker.wordpress.com/2010/10/09/tutorial-a-cross-platform-workbench-program-using-java-opengl-and-eclipse/.
First, don’t use C# for anything that should be portable. Mono is a bad option for GUI for two reasons:
- Mono goes always several steps behind .NET.
- Mono does not support WPF, so the only way to develop GUI is using something like GTK#.
My personal opinion – use C++. It would give you very good portability and independence.
You have two options:
- Qt4 – very good GUI toolkit, makes GUI development very easy, and highly portable.
- GTKmm – also very good toolkit, but it feels less natural on Windows.
Also, Java has Swing toolkit that comes with JDK and is available on all Java platforms, even very strange ones like OpenVMS.
