When changing the style of the combobox, the change will not propagate to the internal container widget, so the changeEvent handler won't be called. This is correct (as per QWidget::setStyle documentation). QComboBoxPrivateContainer asks the combobox style for relevant settings, such as the frame style, which is then used for sizing and positioning. If the combobox's and container's settings become inconsistent, then the combobox popup will not get the correct size and/or position. Move some of the style-dependent changes into a separate function and call it when the QComboBox::changeEvent handles the style change so that both widgets have a consistent set of settings. Add a test case that verifies that the style is asked for the relevant setting when the style changes. Note: QComboBox does a lot of style-dependent setup work in different places, which is quite messy and complex. Trying to consolidate that further breaks tests though, so this change is doing the minimum necessary to fix the reported issue. Pick-to: 6.1 5.15 Fixes: QTBUG-92488 Change-Id: Ia957d504b2d800add26fc0565be727b5c08a5358 Reviewed-by: Richard Moe Gustavsen <richard.gustavsen@qt.io> |
