Hi,
I've posted this report a couple of times but havent received any feedback.
I'm surprised nobody has had this problem with OS3.5 or maybe there's just
something wrong with my code. Anyway, I've done some more digging and so
here it goes again:
I have a category popup on my main form, this works nicely with anything
below OS 3.5. But in the new OS when I tap on the popup and select a new
category, there is some garbage left on the screen, mainly the selection
from the popup list is not cleared when the popup is closed.
I do the following calls:
CategoryCreateList
LstPopupList
CategoryFreeList
Looking at the Palm OS source code for CategoryCreateList I have traced the
problem to LstSetSelection. It seems that in OS < 3.5 LstSetSelection does
some internal list stuff but that's it. While in OS 3.5, LstSetSelection
actually displays the selected item on the screen (!!). This is the problem
because then when LstPopupList get's called, a copy of what's on the screen
at the popup location is saved with WinSaveBits and when the popup closes
the screen is restored with WinRestoreBits but this also restores the
garbage that LstSetSelection displayed before the popup was opened!
Is LstSetSelection broken in OS 3.5 ? Anybody can confirm this ?
Thanks
Chris
