update console log while processing

[ikemarv]

Hi guys,

we want to give our users feedback about a progress of a copy job. The pogress should be visible on the console with the help of a print()- progress bar. Our problem is, that the output is not visible during the copy-process. Instead all logs appears at once, when the job is finished.
We have tried to refresh the console before a print()-method like it's mentioned in this post:  https://www.agisoft.com/forum/index.php?topic=9586.0

Code: [Select]

def start_alignment_process():
app = QtWidgets.QApplication.instance()
input_dir = Metashape.app.getExistingDirectory(
        "Path:")
       
        image_copier = ImageCopier(input_dir, PV_DIR, app)
        output_process = threading.Thread(
        target=image_copier.copy_directory_with_progress, args=())
output_process.start()

output_process.join()

class ImageCopier():
....
def copy_directory_with_progress(self) -> str:
self.app.processEvents()
print("Copy job started")
self.copytree_with_progress(self.src, self.dst)
# Wait for the copy thread to complete
self.app.processEvents()
print("Finished copy job.")
print()  # Move to the next line after completion
return self.dst

Unfortunately, it didn't help. Do you have any suggestions for us?

Kind regards,
Eike Sippel

Hello Eike,

Does it help if you put app.processEvents() after print() lines instead of having them in front of printing lines?

Also I would rather suggest to initialize app as:

Code: [Select]

global app
app = QtWidgets.QApplication.instance()

And then just call app instead of self.app - you can try that, if the first approach does not work.
