<br>
I think, that's the problem i have. Either way of inter process
communication needs some kind of event loop.<br>
Flask runs its own event loop, right?<br>
So, how do i mix these two?<br>

<br>
I'm using flask for the first time and after trying quite a
lot, i still fail. :-(<br>
I am wondering what i am doing wrong and if flask is the right
way to go at all.<br>
<br>
My objective:<br>
- I have a main python application, which basically is
based on a PySide (QT4) event loop.<br>
This runs a bigger state machine and several other
functions.<br>
- Now, i want to add a web interface which reads/sets
parameters and displays a longer list of<br>
strings from the main application (variable length) .<br>
<br>
Where i am:<br>
- The simple flask examples from various tutorials work
fine for me.<br>
- BUT: I cannot combine my main application with flask,
i.e. i don't know how to<br>
interchange the data between my main application and the
flask route-functions.<br>
<br>
What i tried:<br>
- running flask in a thread (QThread). Works fine for a
simple example, i.e. deliver static html<br>
and react on get-request<br>
- run flask in main thread. Doesn't work since some of my
functions rely on the qt event loop<br>
- interchanging data between my main application and flask
in the thread. I tried this using the<br>
qt signal/slot mechanism.<br>
This doesn't work, because the signals which i have to
define in the main application are not<br>
accessible within the flask route-functions.<br>
<br>
<br>
I really hope you can give me some good advice.<br>
I can post code snippets if it helps for clarification.<br>
<br>
Thanks a lot,<br>
<br>
Nik<br>
