Nope, I'm still without my phone thanks to latest Jolla/dnagate.

Good.. I'll just have to write code assuming the main loop lives on
in the real device. Thanks for testing!

Have you ran it on the actual device? It might be that the fix did not
make it to the SDK. It should work on the device, however.

Re: [SailfishDevel] Closing an application without killing the main loop

Hello,

I don't know what's the best way to do it, but here are some ideas.

1. Use aboutToQuit and block it with a QEventLoop ? It might not be enough and 
   might leave the application cover open on the multitask grid, making it 
   look not responding.
2. Launch a script / program when quitting, that performs the async task.

Cheers,
Lucien

[SailfishDevel] Closing an application without killing the main loop

2013-12-11 Thread Ville Ranki 
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1


Hello,

I'm the author of Siilihai web forum reader  and
i'm currently porting it to Sailfish.

Siilihai needs to synchronize it's status (read messages etc) to a
remote server when user quits it.

I have not found a way to do it in Sailfish. When user closes the
application, Sailfish terminates the Qt main loop which effectively
makes it impossible to do any asynchronous tasks.

On desktop QApplication::setQuitOnLastWindowClosed(false) can be
used to instruct Qt to continue running main loop when last
window is closed, but it does not work on Sailfish.

Restarting the main loop worked on Harmattan, but on Sailfish
it causes a crash inside Qt-Wayland code (qwaylandeventthread.cpp line
37). I also tried to create a Qt event filter with no success.


Here is a example application to demonstrate the issue:
http://talk.maemo.org/attachment.php?attachmentid=33970&d=1386249527

This application creates a repeating timer which stops working
when the window is closed.

I have already asked about the issue on TMO and #sailfishos, but didn't
get any satisfactory answers.

http://talk.maemo.org/showthread.php?t=91947

The question is: is this a bug or intended behavior? Can anyone hack
the example application so that the timer keeps running after the window
is closed?
