Getting error on including custom widget class

[rawfool]

On including a custom class widget, I'm getting the following errors. How do I fix this ?

C:\Qt\Qt5.0.2\5.0.2\msvc2010\include\QtCore\qdatetime.h:123: error: C2589: '(' : illegal token on right side of '::'
C:\Qt\Qt5.0.2\5.0.2\msvc2010\include\QtCore\qdatetime.h:123: error: C2059: syntax error : '::'

My custom class looks like this -

Kindly help me fix this issue. Thank you.

hi rawfool,

1.add #define NOMINMAX before including windows.h header.
2.Add compiler switch “/DNOMINMAX”

hope it helps

1.add #define NOMINMAX before including windows.h header.

I didn't include windows.h in any of my files.

2.Add compiler switch “/DNOMINMAX”

Adding QMAKE_CXXFLAGS += /DNOMINMAX in my .pro file solved the problem. Thank you Bala.
