David -
Thanks for the helpful info. Here are the details.
I have been using this code to put a bitmap on my main form at runtime:
ctlIndex = FrmGetObjectIndex( frmP, MainBitMapOne );
FrmSetObjectPosition( frmP, ctlIndex, x, y );
FrmShowObject( frmP, ctlIndex );
In testing with Poser (2.1d29 or 3.0a3) using rom2rel.rom,
FrmSetObjectPosition appears to have no effect. The bitmap is always drawn
at the Form Bitmap's design time location. I found that FrmSetObjectBounds
will move the bitmap on all ROM versions. I checked the online KB and the
docs and I didn't find anything saying that FrmSetObjectPosition won't work
with Palm OS 2.0, so I am left wondering when it is safe to use
FrmSetObjectPosition.
