You were right or at least partially. We set the namespace visibility to yes and updated the Qt version.

Now is working.

Thank you everyone for your help.

For Android, see https://www.qt.io/blog/taking-qt-for-python-to-android . iOS is not supported yet.

@catafest Works great ! Thank you!

@ZeroCool96 if I were you, I would check whether firmata also supports the STM32 and if so, go for it. Otherwise, you will have to implement something yourself. If using the serial port to communicate with the board, you have QSerialPort.

Hi and welcome to devnet,

Depending on your needs you can use QTextEdit's rich text support to create your document and then QPrinter to print it.

@SGaist
I am simply using the foobar2000 software interface for format conversion operations. However, the issue mentioned above is not related to file size. For example, converting a very small MP3 file (about 5MB) to APE format still results in the same problem.

Hi and welcome to devnet,

Can you provide a minimal runnable example with a test database to reproduce this ?

Hi and welcome to devnet,

Can you provide more details about the failure ? Adding --verbose should show more about what is happening.

@J-Hilk
So the current main.py file is:
sample.png
Now I want to know where should I implement this part:
def run_long_task(self):
mutex = QMutex()
worker = Worker(mutex)

def stop_worker(): with mutex: worker.stop_flag = True # Connect the worker's finished signal to stop the worker worker.finished.connect(stop_worker)

because I tried but it was not working. It prompt to force close the UI.
@J-Hilk

I had somehow forgotten that python was involved.

Predictability of object destruction has been a recurring issue for me, although I don't recall seeing a normal program termination result in an object never being destroyed. I also don't remember seeing deleteLater() needing an additional delay as long as the event loop is still running when the function is called.

If there's a brief example that you don't mind sharing, I'm interested in seeing the suspected cause. Maybe it's a new-to-me pitfall that I should be avoiding.

@Christian-Ehrlicher
got it, thanks

@jsulm Fascinating and thanks. I've clearly underutilized the StatusBar. I had been using it to display messages I sent using setStatusTip which looks like it's a QAction/QIcon method since I don't see it in the QStatusBar class. Time to rethink. My first thought is to divide the SatusBar into three fields. The first would be where I put messages regarding starting/finishing/failing commands/menu items. The second would be tool tips responding to hovering. In the third, I might place some program setting states. The third would be right justified while the first two would be left justified. That's my first guess. Am I correct this can all be done with QStatusBar? That's my quick reaction to the documentation.

@jsulm ahh.. got it 😄. Thank you
