Summary0004456: Qt5: QComboBox becomes empty after selection changed
Description

If a "regular" combobox (i.e. QComboBox, for example any combobox in Application Settings or the W/L combobox in Volumes) is clicked and its current value is changed, then the text shown in the combobox disappears. It re-appears on the next mouse click anywhere or any key press.

Additional Information

Windows 10, Qt 5.9.1, latest trunk at the time of adding the issue.

TagsNo tags attached.

Cannot reproduce on MacOS Sierra, and Qt 5.9.1 using master on 11/06/2017.

Thanks! This may be Windows-specific then.

@hina-shah: Can you please try again? Make sure you don't use a MRML combobox, but a regular one. Like the ones I mention above, or the module selector combobox. Thanks!

Sorry for taking long to respond. I tried again with yesterday's master, Qt 5.9.1 . Loaded a Volume, went to the Volumes module, W/L combo box, and then switched between Auto W/L, Manual W/L and Manual Min/Max. The text in the combo box remains intact. Also tried the same with Application Settings: for example changing the orientatin marker in Views from None, to axes, and to humans. The text remains as it should be.

However, after I loaded a volume, a LOT of the menu items grayed out for some reason. (Application Settings included).

Thanks! Can you include a screenshot? I'm not sure what grayed out exactly means in this case.

I saw the qComboBox issue on the latest master today, so it's definitely a problem on Windows.
