Best Language For Experimental GUI Demo Projects?

New submitter GrantRobertson writes with a question about quickly developing prototypes for new interface design concepts "My research/tinkering will be along two main lines: (1) Devising entirely new graphical user interface elements, mostly in 2D, though often in a true or simulated 3-D space. I am working on ways to visualize, navigate, and manipulate very, VERY large data-sets of academic research information. (2) Computer based education software, though of a type never seen before. This will combine some of the GUI elements invented in (1) as well as displaying standard HTML or HTML5 content via a browser engine My requirements are: (A) A decent IDE ecosystem; (B) A decent set of libraries, but ones that don't lock me in to a particular mind-set like Swing does in Java. (Boxes in boxes in boxes, Oh My!); (C) An ability to easily draw what I want, where I want and make any surface of that 3D object become a source for capturing events; (D) Ease of cross-platform use. (So others can easily look at my examples and run with them.); (E) No impediments to open-source licensing my code or for others to go commercial with it either (as I have seen when I looked into Qt). So, should I just stick with Java and start looking outside the box for GUI toolkits? Or is there something else out there I should be looking at?" I'm not sure what impediments Qt has to proprietization of software since it's LGPL nowadays; in any case, Qt Quick and GNOME's Clutter seem like they could be a useful. Read on for more context. "I am not a professional software developer and never have any aspirations to become one. I've been through a generic university computer science degree-program and I can tolerate C++ begrudgingly. I do OK with Java and prefer it, though I still have to look up every API before I use it. Most of the code I want to write will be not much more than prototypes or proof of concept stuff for the research I will be doing, rather than full-on applications ready for distribution and use. I can learn any language out there, if need be, but these days it is more about the ecosystem than the core language. IDEs, libraries, cross-platform compatibility, user support, open source licensing."

    In the demo phase, you're not really worried about performance. The goal is to have something showing as quickly as possible, and not worry too much about how fast it runs, or how much memory it takes. Overspec your demo system for the time being (ie - make it really fast and install lots of memory), and once you have a reasonable interface go back and recode it in a simpler language which can be more easily optimized.

    Languages which are simple to learn (c++, for example) are generally not very expressive. You end up wasting tons of time debugging issues of memory allocation, library interface details, and datatype conversion.

    Languages which are expressive are a little harder to learn, but any individual line in the expressive language does a lot more. Since you are writing fewer lines, and since the fewer lines do more, you end up making programs more easily and in less time.

The compiler itself has very speedy compilation times compared to C++ compilers, and generates decently quick code as well. The compiler itself is very mature and well maintained, and it gaining new features all the time. Lazarus is the IDE, which provides you with a RAD environment to quickly piece together the UI, and it is packed with all kinds of awesome features. The LCL, it's supporting library, wraps all of these functions up in a way that makes it very easy to deploy cross platform applications. It covers OSX, Linux (GTK+ and Qt), and Windows. The Free Pascal compiler can compile code for many more platforms, and has in fact supported some even before GCC. If you stick with the LCL, just about everything is covered between platforms and it uses the native components of the platform it is compiled for. It has a very healthy community, with plenty of bindings for all different kinds of libraries. It also provides a good method for creating custom components and reusing them, allowing you to install them in to the IDE and drag and drop them in the form designer just like you would with a standard button or text box. I've never done any stuff with 3-d graphics, but there's all kinds of OpenGL stuff available, and anything you can do in the native widgetsets you can do with Lazarus. The issue with Lazarus is that the IDE is still beta, and there still are a few bugs here and there, but they are fixed pretty quick, and there aren't any major show stoppers. The big issue is that it uses GDB for debugging (there is a native Object Pascal debugger in the works, but it won't be finished anytime soon), which is really aimed towards C based languages, so debugging isn't always smooth. Most of the basic tasks, like setting breakpoints and stepping through a program/function work fine, but there are a few issues with the differences between Pascal datatypes and C datatypes that can make things confusing.

    The reason I recommend this tool is because even though it doesn't have a massive ecosystem like C++, it is coherent and works very well between platforms. The Object Pascal language is very easy to learn, it's powerful, and well designed. While not as fast as C or C++, is you look at the alioth debian language shootout page, it is pretty quick compared to other languages. It provides access to all of the familiar C library functions, and includes all kinds of stuff in the language for compatibility with the C language. It's not the old Pascal from the Turbo Pascal days that people like to bash, almost all of the complaints I hear about the language itself were taken care of a decade ago.

    "run rings around it" is a matter of opinion. I've used all 3 in anger, and I'm far and away more productive in Cocoa. Of course you'd use the gui interface builder (on either GnuStep or cocoa), that's an integral part of the system.

    Pure cocoa would get you farther, easier - the GnuStep stuff imposes limits, but personally I'd use core data for persistence, quartz composer for data visualisation, Grand Central for parallelism (using NSOperation) and you can drop into C or C++ for performance when you need to. All basic building blocks that work well together and ObjC is far nicer to work with than plain old C and desnt have the gargantuan complexity of C++.

  31. Lots of people write ObjC GUI code by SuperKendall · · Score: 3, Insightful

    virtually nobody writes the GUI code by hand. wx and Qt run circles round it.

    Both statements are false.

    There is a whole school of thought that people should shun IB for better UI performance. As a result there are lots of people that write all UI elements by hand. It's not hard, but there are a lot of properties you usually need to tweak.

    I myself like to use IB when possible, but have also done a LOT of dynamic UI, including building whole screens dynamically from configuration files.

    On performance - frankly you are dreaming if you think wx and Qt run circles around iOS UI elements, which have all the rendering accelerated by the graphics hardware (since every view is really a plane in a 3D world!).

    No. Just use paper and pencil. Create a story board, http://en.wikipedia.org/wiki/Story_board, showing how the user will use the interface.

    Go to the academics that represent your users. Ask them what they want to see in a visualization, how they expect to do a search, how they expect to manipulate things. Give them paper and pencil and tell them to just draw things however they think it should be, not what they are used to seeing in their current environment and applications, rather whatever they can imagine would be a good way, a way that feels natural.

  33. So: I want X, but not in Y, even if Y supports it? by VortexCortex · · Score: 4, Interesting

    Why not just use Flash & ActionScript, along with Unreal. Specifically, Scaleform. Since it already does the "never before seen" 3D GUIs you want, and game engines are particularly good at visualising extremely large data sets (we call them game worlds).

    Any amount of searching "HTML 3D" would have turned up WebGL, which uses OpenGL in existing browsers... That would be a good prototype platform for me.

    I take particular issue with the childish statements against using Java (and Swing), considering they already support 3D Swing components (see XTrans demo). Swing displays HTML components, even in tool tips. In fact, there is already an entire 3D collaboration framework in Java ready for any "Never Seen Before" GUIs you wish to dream up... It displays HTML, images, & PDFs etc.

    Furthermore, their indignant remarks smack of ignorance, considering Java 2D & Java 3D exist, and both have rich non standard box shape intersection libraries, which can be used to create custom components of any shape or position, hierarchical or not restricted only in that they should be used in a Canvas, to save yourself some time.

    They want someone to hand them a magic library that has all the bells and whistles already to go, but heaven forbid any of them have an API that requires using... Have fun inventing that shiny new wheel.

    You don't need anything special to link to LGPL code. You can do it with proprietary, commercial code. You don't need to release your source code when you link to LGPL libraries.

    Unless you are modifying the library, then you need to release the changes. But you shouldn't have to modify QT itself.

    Absolutely, seconded.

    Without a doubt, QT is the reigning king of quick, pretty and cross platform GUI development. And of course you would do that with C++ if you want your code to be most widely portable, and to put your demo in the best light by starting fast and responding fast. But QT works well with many other languages, including having excellent Python support. Here is an idea: use Lua both to drive your demos and be the embedded scripting language at the same time. That would rock.

    While I do not think you should have been modded troll, I don't think Haskell is best suited for interface. Interfaces typically require a lot of state. Setting up state monads for all that would be painful. And then there's the GUI libraries, does Haskell even have those.

    On a more generic note, Haskell's ecosystem is not ready for prime time. Where are the debuggers? Don't feed me the function language crap, if you cannot produce a decent debugger for a language, no one will use it.

    The type system is wonderful, until something goes wrong. Haskell's feedback about where the type mismatch occurs and why is horrid.

    Not that I am saying you should use these tools although it seems they are one possibility.

    Here are links related to a quite interesting software project developed by Christophe Mertz and others at CENA.

    The Digistrips system was a user interface prototype demonstration system written in Perl for the design of new touch screen based air traffic controller systems that mimic the traditional system in which paper strips are used to represent aircraft in flight. The demonstration is said to have been successful, and there are a number of papers written about user interaction in the system.

    It used Ivy (a cross platform message bus in Perl) and TkZinc (an OpenGL and 2d capable canvas).

    Below are numerous links to papers and software sites although the openatc.org website is no longer in service itself. It is possible to download Ivy and TkZinc it seems.

    Ivy is a simple protocol and a set of open-source (LGPL) libraries and programs that allows applications to broadcast information through text messages, with a subscription mechanism based on regular expressions. Ivy libraries are available in C, C++, Java, Python and Perl, on Windows and Unix boxes and on Macs. Several Ivy utilities and hardware drivers are available too.
    Ivy is currently used in research projects in the air traffic control and human-computer interaction research communities as well as in commercial products. It is also taught to CS students.

    TkZinc is a Tk widget developed with Perl/Tk, Tcl/Tk and Python/Tk bindings. TkZinc widgets are very similar to Tk canvases in that they support structured graphics. Graphical items can be manipulated, and bindings can be associated with them to implement interaction behaviors. But unlike the canvas, TkZinc can structure the items in a hierarchy, and has support for affine 2D transforms. Clipping can be set for sub-trees of the item hierarchy and the item set is quite more powerful, including field-specific items for Air Traffic systems. TkZinc is fast enough to allow the implementation of 2k2k radar displays with smooth animations. It is structured enough to allow the implementation of direct manipulation desktop GUIs.

    Since the 3.2.2 version, TkZinc also offers as a runtime option, support for openGL rendering, giving access to features such as antialiasing, transparency, color gradients and even a new, openGL oriented, item type : triangles. In order to use the openGL features, you need the support of the GLX extension on your X11 server.
