console log:
SetCurrent Index 2 7 7

but combobox does not switch to index

when check combobox->currentIndex() log to console expected but not show. I dont understand

You've got m_outputPowerComboBox->setModel(m_outPutPowerModel); in your code, correct?
as well as m_outputPowerComboBox->setModelColumn(which column of the model you want to display)

Are items showing up in your WComboBox, but you can't do anything with the index?

For what it's worth, I'm using it all over the place in 4.10.1 and it works fine.

Hi Cemal,

your example is not really sufficient for me to be able to reproduce your issue. From a glance, I would suspect the Wt::ItemDataRole::User may be the culprit here, unless you of course added that to the model.

I would appreciate a minimal viable example, so I can examine this issue, and if necessary create a fix for it.

Best regards,
Matthias
