Bulent,
I believe it displays the 1 bit family member because the current screen bit
depth is 1. Even though the Vx can display 2-bit and 4-bit bitmaps, the
default screen depth is 1-bit. To change the screen bit depth, if your
device implements the 3.5 New Feature Set, use:
UInt32 depth = 4; // or 1 or 2 or 8
error = WinScreenMode(winScreenModeSet, NULL, NULL, &depth, NULL);
or, if it doesn't implement the 3.5 features, use:
error = ScrDisplayMode(scrDisplayModeSet, NULL, NULL, &depth, NULL);
This is all described in the Palm OS SDK Reference. If you didn't know
where to find the answer, this also would have been a good question to
submit to the Palm Development Forum.
Have a great day.
