WinBackground |
Function (ROM Call 0x4) |
Sets the default window background.
WinBackground changes the current default attribute for the background of a window
pointed to by w (used to clear the window using WinClr).
Note that the background attribute is also used to fill up a newly created area when
a window content is scrolled in any direction. Valid values for Attr are:
A_NORMAL | Black background |
A_REVERSE | White background |
A_XOR | All pixels will be reversed during clearing |
See WinAttr for more info about attributes.
Note: TI said that attribute A_SHADED (set to a pattern of pixels on and off) is also supported,
but it didn't work when I tried it; at least, it does not work on AMS 1.00.
