So ,in filesave *.cpp ,the value is 0xbffcc8fc.
i dont understand the codage of color.......
white normaly will have the value :255 255 255====>what s the result of this value after coding

Thanks:o

These are the hexadecimal values of rgba(red,green,blue and alpha-channel i.e., transparency).

In your case it should ideally be 0xffffffff

0xFFFFFF

Maybe your coding your white somehow incorrectly or it's not white at all (or it's using some different colourspace than (A)RGB).

thanks
But,in this expression :
0xbffcc8fc,
bf --->R
fc---->G
c8----->B
fc----->alpha chanel

????that s true or false
if it s true, can i convert 0x** ** ** **to 0x****.
thanks to all

You can use QColor red(), QColor green(), QColor blue() to get the integer values and play around. Alpha channel by default is 255(ff).

How did you receive that value anyway?
