Nokia Closing Australian Office, Looking To Sell Qt Assets

Posted by Unknown on from the this-isn't-funny-any-more dept.

An anonymous reader writes "One day after word leaked out that Nokia is shutting down its Qt Australia office, which is responsible for Qt3D, QtDeclarative, QtLocation, QtMultimedia, QtSensors, and QtSystems, reports are beginning to surface that Nokia is trying to sell off all Qt assets." Seems like selling itself to Nokia wasn't the best option for Trolltech after all.

      Not really; look at the state of exception handling in C++ and get back to me about "high quality" software. In fact, Qt's own documentation says this:

      Exception safety is not feature complete! Common cases should work, but classes might still leak or even crash.

      And,

      Qt itself will not throw exceptions. Instead, error codes are used.

      Which is not to mention the incoherent uses of exceptions and error codes in the C++ standard library.

      Pretty strong and incorrect comment from a coward.

      Qt largest growth sector is embedded systems and QML Is the driving force behind this market. You cannot get the performance from Widgets that you can from QML objects (Well you can if you rewrote the widgets in a light weight framework like QGraphicsView or SceneGraph, but then you would essentially have QML.)

      I don't know where you get your facts, but QML behaves very well in highly animated GUIs on fairly low end embedded hardware. The fact that it is backed up with a highly optimized SceneGraph engine that removed the overhead of the QGraphicsView engine makes QML even better performing.

      The comment above about Digia is greatly misleading. Digia focuses on the commercial license market which is a legacy business. The growing embedded market uses the LGPL version and gets support from the open source community. Companies like ICS and KDAB are growing at a very fast pace servicing this market. Digia has not been able to transition well to the embedded space.

      The problem is that "high quality software" should handle errors -- it should not crash when an error occurs (in the worst case, it should gracefully shut down), and it should not ignore errors. Error codes are fine as long as you actually handle them, but in practice the effort required to check the return value of every function call (and you think checked exceptions are annoying?) leads to some errors not being detected or handled. That is why exceptions are good in theory; but if in practice, an exception can cause a program crash even when there is an exception handler waiting to catch the exception (this is the case in C++), then they are not a good way to deal with errors.

      As for embedded systems, if there is enough computational power to display a GUI, I really do not see how exceptions are problematic.

      You seem to be wrongfully blaming deficiencies in Qt's implementation on the langauge

      I was originally replying to a post that claimed Qt was the "best" toolkit for writing "high quality" C++ programs. Qt uses error codes, not because error codes are a good thing (they are not), but because Qt is a C++ toolkit and C++ makes anything other than error codes unreliable. How is that an unfair criticism?

      I've written numerous pieces of complex software with Qt using exceptions and have never seen an exception fail to be caught or ever let errors go unchecked

      Except that preventing exceptions from crashing your program in C++ means preventing some exceptions from propagating -- and basically forces you to create programs that do not handle certain errors. In C++98, you could just risk a double exception fault, but it was considered bad practice; in C++11, you can't even take that risk, and so your destructors either have to handle the error properly or you need to find some other way to signal the error (or else let it go unhandled or just quit). On some level, you are either not using exceptions at all or else you are allowing some exceptions to be ignored -- that's a reality of C++ exception handling.

      I've used tons of crappy Java and .Net

      Did I say that Java or .NET are better? In all of these systems, exceptions could have been done better -- for example, by not destroying the stack before the exception handler executes. Java won't cause your program to abort when exceptions are thrown, but Java will cause exceptions to be "forgotten" under some circumstances:

      try {
      } finally {
      throw new SomeException();
      }

      That is not much better if you want "high quality" software.

      You might want to update your C++ hater points beyond what you read on yosefk.com or other lame whiner sites.

      Lame whiner sites? I programmed C++ for a decade, and I still have to write C++ code sometimes. My dislike of the languages comes from experience, not from some website. Error handling is just one issue, one that I think is very much relevant if we are going to talk about "high quality" software. Programming in C++ requires knowledge of the long list of undefined behavior, the long list of patterns that have to be used to avoid that behavior (which hardly anyone deviates from, except for novices who have not yet learned the patterns), and debugging is as much about correcting bad program mechanics as it is about correcting bad program logic (and the majority of C++ code is not low level code).

      Yes, I know, programmers should just follow best practices; if that is the case, why not just make those practices standard, and create a special statement to disable that behavior? Why are we forcing programmers to explicitly say, "I do not want this program to crash," when we could be forcing them to be explicit in situations where they do want to write potentially unsafe code?

      They could have made widgets hardware accelerated and easily animated.

      Yes. And that's how QML came to be, because when you actually try to make "widgets" do all that you end up with something that's not widgets anymore. Do you seriously believe that the mindset was "let's come up with something new from scratch, we've got too little work to do"? The legacy widget model has insurmountable performance issues that cannot be overcome in that model. If you don't understand that, you need to do some research first, perhaps actually try coding something up and convincing everyone how your supercool painter widget based model keeps up with competition.

      There's no way to get good performance from a painter-based architecture that asks everyone to repaint their part when something changes. This model made sense for a while because common graphics hardware was generally slow and had no acceleration to speak of when it comes to graph-based representations of the visuals. It doesn't make any sense anymore. When a window moves and is to be recomposited, you shouldn't have to transfer more than a command or two to the graphics card to change a couple coordinates. It'll be picked up next time the rendering is done. In the painter-based model, at best you have backbuffers for every window (even if a window has a flat background that can be represented by two flat shaded triangles -- two dozen numbers at the most, not a megabyte), and those backbuffers have to be composited.

      The widget model not only sucks performance-wise, but it also sucks resource wise: you need a lot more memory and a lot more memory bandwidth to render even fairly simple things.

      GTK+ apps look out of place on Windows, even more so on Mac. In addition to that, Qt just integrates a lot better into the native tool chain (e.g. Visual Studio, Xcode).

It's benefited immensely from being backed commercially and it shows.

      I wish to elaborate on why the painter model is inefficient with today's GPUs.

      The painter employs an imperative approach that does not allow for much freedom. Example: begin(), line(), text(), line(), end(). The two line() calls should be grouped together, but they cannot, because then the result would not be equal (what if text() drew over the first line, then the second line() call drew over the text for example?). The result is pretty bad: the underlying implementation has to perform tons of unnecessary shader switches (since font rendering most likely uses different shaders than the line drawing code), and perhaps texture switches (if texture-based AA is used). In addition, every time the painter is used, a vertex buffer has to be filled with vertex data. It cannot be easily cached. And this applies to *every* begin..end painter sequence.

      A declarative QML-like approach is a much, much better idea. The fundamental reasons are that (1) the renderer now always has a global picture of what the frame shall look like, (2) intermediate results are much easier to cache, (3) no strict sequence of drawings is given, therefore the renderer is free to reorder and merge drawcalls in any way it wishes. This benefits even pure CPU-based rendering - the Enlightenment Foundation Libraries render using a graph, and are extremely efficient (they clip and cull primitives early on, group primitives together, IIRC can even detect accumulated opacity from several alpha blended layers ..).

      C++ QML bindings would likely consist of an API that can modify the graph. Either way, the painter-based approach is gone.

A friend of mine at Nokia doing Mac development with Qt admitted as much.
