  • c++ - Using QProgressDialog properly - Stack Overflow
    connect(m_progressDialog, QProgressDialog::canceled, [ ](){ m_progressDialog->show(); }); Note that you still can't do that while using WA_DeleteOnClose (since the dialog gets deleted anyway), so I would advise you to avoid setting WA_DeleteOnClose, and instead to store your dialog in a QScopedPointer

    I had this same problem, when i had a modal QDialog and a QProgressDialog and the QDialog would always be on top despite the QProgressDialog coming from the QDialog itself The issue was the lack of a parent assigned to QProgressDialog; just make sure that you assign the widget that spawns the QProgressDialog to be the parent
  • How to ensure QProgressDialog is shown in PyQt - Stack Overflow
    However, I have noticed that when my QProgressDialog does not show it occurs when I am accessing a text file using a config parser The work around was to do a time sleep() after the file has been closed (perhaps to ensure the process completed and that processEvents would then commence showing the QProgressDialog)
