If you are going to post code to support a question about compiling or linking:

Paste the actual code that generates the error, and some context lines around it.
Tell us which line or lines the error relates to.
Copy and paste the actual error message and some context lines before it.
Test us something about your build environment: Operating system, Qt version, compiler version etc.


Nothing in the code snippet you have posted helps us connect to the error message you posted.

plalette.setColor(QPalette::Window,colorrgb);
this line occur.
If I change the code as follows,it is ok.But it is not what I want.

plalette.setColor(QPalette::WindowText,colorrgb);

I use vc2005+qt4.6.3
