@SGaist thank you for your help, QApplication.setStyle(QStyleFactory.create('windowsvista')) is effective

@JonB said in How can I release a pdf document for use again after it has been used with QPdfView in PyQt?: self.pdf = None self.document = None self.pdf = None gets rid of self.pdf.document. self.document = None is necessary because you have self.document = QPdfDocument().

I'll use the workaround for now, and post there to see if they can identify anything related to PyQt. Thanks for the help.

@krish_garg There are many ways to implement this, depending on what UI you want (e.g separate widgets/windows/dialogs, MDI, QStackedWidget). Since you mention a "back" button, the one Qt class which gives this is QWizard Class if what you want is a step-by-step guiding the user through a number of sequential pages, which allows user to go back to change their answers. That does not address e.g. a separate "all contacts screen" but might be what you want for adding/editing.

@JonB thank you! Sometimes it happens that everything gets mixed up in my head: Python, PyQt... and I'm no longer sure if I can do something straightforward. I'll try to call the method directly

@ZHLN You did not put the label in any layout and you did not call show() on that label. You need to do one of these, else it will not be shown at all.

@jsulm thank you so much! You solved my problem :)

It is not really clear what exactly you did. What is BaseWidgetWindow? If you're imnplementing a custom title bar then take a look at https://github.com/imitatehappiness/QtCustomTitleBar

Problem Description: There is an issue with the setPageSize method of QPrinter in certain versions of PySide6, PyQt6, and some versions of PyQt5. Solution: The setPageSize method works properly in the PyQt 5.13.0 version. Recommendation: If possible,downgrade to PyQt 5.13.0 version, or look for specific fixes regarding the setPageSize issue. bug i have not solution in PySide6 version, I need solution too!!!!!

Hi and welcome to devnet, Without any code it's impossible tell what is happening

@AlexP11223 It's much simpler to use Qt's asynchronous nature e.g. QTcpServer. No need for threads, multiprocessing or blocking.

@redhead Hi, It's working correctly on macOS with PySide6 6.7.2.

@jsulm ahh.. got it 😄. Thank you

@SGaist Thanks for your reply. I appreciate that the tool itself wouldn't dictate the licence terms, but was curious as to whether it said anything about the Qt Company's view in whether the resulting package would be LGPL compliant from the perspective of the PySide and Qt Libraries. However, since that original message I tried out pyside6-deploy and realised that there's no way the resulting package could be compliant (in terms of allowing modified versions of the libraries to be swapped in) due to its use of Nuitka's onefile option.

Hi and welcome to devnet, I think this article is still valid.

@JonB I see. Thanks!
