[Qt-interest] 答复: compile failed

[Xiaolei Shang]

 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?
