error C2039: 'hwnd' : is not a member of QPalette

[weixj2003ld]

I use the follow code to set the background color of a a QLabel:

QColor colorrgb(x*255,y*255,z*255);
	QPalette plalette;		
	plalette.setColor(QPalette::Window,colorrgb);
	colorlabelreal->setAutoFillBackground(true);
	colorlabelreal->setPalette(plalette);

QColor colorrgb(x*255,y*255,z*255);
	QPalette plalette;		
	plalette.setColor(QPalette::Window,colorrgb);
	colorlabelreal->setAutoFillBackground(true);
	colorlabelreal->setPalette(plalette);

To copy to clipboard, switch view to plain text mode 

but the follow error occur:
error C2039: 'hwnd' : is not a member of QPalette
error C2275: 'HWND' : illegal use of this type as an expression

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.

[weixj2003ld]

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
