When you used Designer to develop GUIs, the Qt generates ui_....h files which define all widgets variables and configurations. When you removed some widgets and added them again at other places, I think the generated ui_.h files get confused codes. So make sure that you make clear build if you do those types of operations.

>From your snapshot of the widget, I found that an interesting thing: it's Chinese and English mixed widget. Is this for Chinese or English?

Hi All

         I know why.

Because I added QGroupBox first, then added the QScrollArea, and then I moved QGroupBox into QScrollArea. so, I could not compile it.

Now, I create a new program and add QScrollArea first, it is compile successful.

Anybody could tell me why?
