Data source UI freezed while the invoker application is also QT based

Closed this issue · 1 comments

I created an app based on QT. When integrating this data source, the UI of this example data source freezed. I guess, it related to the message loop mechanism. But I can't fix this issue. Would you please provide an patch or some advice? Thanks a lot.

Sorry, please close this issue, it is all my mistake.
My QT app processes native Windows message in a wrong way, so I fixed it.
