a question about entry

[Jiang XU <jiang xu echostar com>]

The entry, no matter in which state, the area which is used to input the
string is always white.
I can change the font and color of the string which will be shown in
this area, but I never can change the color of that area (the always
white area).

I wonder whether I can change it? if I can, how?

Thanks

Jiang
