How to set my QPushbutton's background?

[cspp]

and if I set the add this code:

colorButton->setFlat(true);

colorButton->setFlat(true);

To copy to clipboard, switch view to plain text mode 

the button's background wiil be set.
but I don't want to set the flat true!

I did change flatness of a button, just compiled your example and it works.

btw, I tested on Qt 4.5.0, which version of Qt do you use?
PS. also read this, maybe you already know this.

QMake version 2.01a
Using Qt version 4.3.2 in D:\Qt\4.3.2\lib

maybe this is a bug in this Qt version, try to compile you code with older Qt version.

I compiled my code in QT4.5,
it works well.

I think it just some Bug in Qt4.3.2!

yup, I don't remember the task number, but it was on the tracker.

I followed the exact code to update the QPalette to change the QPushButton's color but it never showed the color. I compiled my code for Qt 4.5.3 on *both* Unix/X11 and Qt-Embedded, none worked I tried Qt Designer as well, color's not shown either. It works with style sheet, but what I'm trying to have a blinking button that changes colors ever 0.5s, and just that eats up 95% CPU consumption! Admittedly we don't have a very powerful one so I was hoping using QPalette would help the performance.

Anyhow, do you guys have any more ideas? I do have a style sheet applied at the top level Form, but it should be overwritten when I update palette for a particular button, right?

Thanks in advance.

can you show us you code?

In my example,I use the setStyleSheet,it works well.But in my application,it will be crashed!
I have no idea

the crash infomation is:

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

In my application,I have a framework,it will be load some QLibrary,in the
Lib,it wil create some widget,like QPushButton,like the listColorBtn.
and now when I setStyleSheet in listColorBtn,it crashed!
