    My QComboBox popup disappears when clicking on it. To keep the popup visible I need to hold the mouse button which is not nice.
    This only happens with my QComboBox that has ~60 items but not with the one with ~10 items.

      I did an ugly hack by subclassing QComboBox. Set the QComboBox editable, no insert, and the line edit as readonly.

          @SGaist on GNU/Linux. I think it happens because the popup spawns right below the mouse cursor, because it instantly selects what is below the cursor then. Also happens in GTK.

            I set the application style to Windows and it works now, the combobox popup is a dropdown list now.
