[Qt-creator] Code completion glitches

[Wei Mingzhi]

Hello,

First, thanks for your work on the IDE. It's looks quite cool.

Here are 2 glitches which I noticed about the code completion in the
current 0.9 version:

1) after adding some widgets in a UI designer, the added members won't
show in the completion list immediately until I restart the IDE.

2) if I try to #include some standard C/C++ includes (like stdio.h),
the IDE will show an underline in the #include line which indicates
that the included file doesn't exist, and when I type "printf(" the
hint window also won't popup. However the code itself compiles & runs
fine.

Hope these can be fixed in the next version :)

Regards,
Wei Mingzhi
