I have a list on a form that is populated via a list draw function and
LstSetDrawFunction. The list is populated with the correct values
from the draw function.
I have a button on the form that kicks off the following code segment to get
the text for the currently selected item in the list.
If the low-memory access debugging flag is enabled in POSE, the following
error occurs
application " has just read directly from low memory "
followed by a bunch of descriptive text about how this is not allowed in the
Palm OS. This error is triggered by the line of code
CharPtr listItem = LstGetSelectionText( pList, wSelected );
If I disable the low-memory access check, the text returned to listItem is
garbage.
This error does not occur if I do not use the LstSetDrawFunction with a
drawing function, but rather populate the list using only LstSetListChoices.
What I am missing?
Thanks!
--- code segment ---
FormPtr pForm = FrmGetActiveForm();
// get the selection index from the list
Word wID = FrmGetObjectIndex( pForm, MainLstMainList );
ListPtr pList = (ListPtr) FrmGetObjectPtr( pForm, wID );
Word wSelected = LstGetSelection( pList );
// get the text at that index in list
CharPtr listItem = LstGetSelectionText( pList, wSelected );
--- end code segment ---
