Replying to my own question (actually, not sure my first message made it to the list), a helpful colleague found the following:
https://forum.qt.io/topic/98059/push-button-label-settext-not-refreshing-under-macos which leads to https://bugreports.qt.io/browse/QTBUG-68740 and https://bugreports.qt.io/browse/QTBUG-68521. I have a small test project that shows that those bugs are back with Qt 5.15.2 and 5.13. Should I reopen the bug(s), start a new bug? I figure there is no hope of getting them fixed with the current emphasis on Qt 6 but at least if someone else experiences this issue then it might be nice to have the issue documented. I was able to reproduce the issue on macOS 10.14 and 10.15 but not macOS 11 (Big Sur) and Windows 10. All were running the same conda virtual environment. Same in the sense that the same commands were use to generate each environment on each respective system. -- Mike Jackson On 6/28/21, 8:46 AM, "Michael Jackson" <mike.jack...@bluequartz.net> wrote: We have developed a small GUI app using Qt 5.15, PySide2, and Widgets. There are a few instances when running the application that QLineEdits or QListViews are not updating after we update the underlying model or even just do a “setText()” (in the case of QLineEdit). If we resize the app window then we see the new values. I’ve not seen this behavior before with our C++ Qt apps so I’m wondering if we just missed something that needs to be done for PySide2 apps? Here is our setup. MacOS 10.15 and MacOS 11.4 Anaconda virtual environment running Python 3.8. Here are the setup commands to build the environment. conda create -n easybake python=3.8 tqdm requests pip install pyside2 pip install dataclasses-json The project is located at https://www.github.com/bluequartzsoftware/MetaForge We have resorted to a few "workarounds" such as setting the widget visible(fasle), visible(true) after we do the "setText()". Clearly we are just missing something simple. I hope. Thanks for any help/pointers. -- Michael Jackson _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
