Felix and QtJambi: QApplication.exec() locks the main thread
by Piotr Korzuszek
::
Rate this Message:
Hello,
I'm trying to make Qt and Felix work together. The problem is that when I run the Qt main loop (QApplication.exec()) the main thread is locked until the GUI is closed (so Felix is too). I cannot put this in seperate thread because it complains to me about not being in the main thread. On the Qt forum developers motivates this behavior by Mac OS X GUI system that must be handled in the main thread. Any ideas how to solve this? -- Pozdrawiam Piotr Korzuszek piotr.korzuszek@... |

Hi, QTBambi has to be initialized in the main thread. So, the init method has to be called in the Main thread ( the thread executing the main method). However, on Mac, you must set the -XstartOnFirstThread to execute the main method in the Main thread.

Hi Clement, thanks for reply,
Sorry, but I knew that already. The thing is that when I put QApplication.init() and QApplication.exec() in bundle start() method then I cannot do anything in Felix console after running that bundle, because start() cannot return. I've tried to run QApplication.init() in Main thread and QApplication.exec() in other thread but this only results in this: --- QApplication::exec: Must be called from the main thread --- Or maybe I misunderstood you?

No, Felix does not start bundle in the main thread (it is absolutely not required). So, it will not work if you try to call such method in the start method of a bundle. It has to be in the main thread : i.e. initialized externally.

Are you sure? Because I'm just running Qt in start() without any error.
Anyway I have an idea: to use this http://felix.apache.org/site/apache-felix-framework-launching-and-embedding.htmlto run Qt init before Felix and then load other bundles, but I don't know how to make them to access Qt classes yet :-), neither if this is really a good idea.

That's what I did. Initializing QT. Starting Felix, Provisioning all the bundles, and calling exec.

Looks like running Qt before Felix and Felix in separate thread works good
enough :-) Thanks for your help! On Fri, Oct 9, 2009 at 10:22 PM, Clement Escoffier < clement.escoffier@...> wrote: > > On 09.10.2009, at 21:54, Piotr Korzuszek wrote: > > Are you sure?
