nanogui: Thread: color problem

Hi,

I am using uClinux 2.6.17, Nano-X 0.90 in my project (an embedded
product: a color graphic LCD and a keypad...).

I got a problem about color.

I am using the following statements to display a filled rectangle, a
string of text, a line. 

GrSetGCForeground(MainGC, YELLOW);
GrFillRect(MainWindow, MainGC, 30, 10, LCD_WIDTH-60, 50);
GrText(MainWindow, MainGC, 10, 80, "Sub Menu 8", -1, GR_TFASCII);
GrLine(MainWindow, MainGC, 10, 90, 100, 170);


The text is shown in correct color: YELLOW. However, the filled
rectangle and the line are NOT shown in color YELLOW, it's shown in a
different color: MAGENTA.


The same GC is used. How come text, filled rectangle and line are shown
in different color? What may cause this problem?

I wrote LCD framebuffer driver by myself. I am not sure if anything in
my framebuffer driver causes the above problem.

Any suggestion will be highly appreciated.

Regards,

Allen
