Hi,
I'm just starting Palm programming, and trying to implement a table with a list of
patient
I know this is not the good way to asking, but I have no iead what's wrong in my code.
I just fallowing what "Palm programming for Dummies" told.
Could you kindly have a look at the code and tell me what I am missing ?
------------------------------------------------------------------
CharPtr patnames[] = {"Lein", "Craimmer", "Gorgey", "Sienfield", "Jerry"};
VoidHand PatientHandles = 0;
static Err PatientBlock (VoidPtr table, Word row, Word column,
Boolean editable, VoidHand *dataH, WordPtr dataOffset,
WordPtr dataSize, FieldPtr fld)
{
FieldAttrType attr;
CharPtr p;
VoidHand *handles;
FldGetAttributes(fld, &attr);
attr.editable = 0;
attr.underlined = 0;
attr.justification = rightAlign;
FldSetAttributes(fld, &attr);
if (!PatientHandles) {
ULong numBytes = TblGetNumberOfRows(table) * sizeof(Handle);
PatientHandles = MemHandleNew(numBytes);
handles = MemHandleLock(PatientHandles);
MemSet(handles, numBytes, 0);
MemHandleUnlock(PatientHandles);
}
handles = MemHandleLock(PatientHandles);
if (!handles[row]) {
handles[row] = MemHandleNew(StrLen(patnames[row])+1);
p = MemHandleLock(handles[row]);
StrCopy(p, patnames[row]);
MemHandleUnlock(handles[row]);
}
*dataH = handles[row];
*dataSize = MemHandleSize(*dataH);
*dataOffset = 0;
MemHandleUnlock(PatientHandles);
return 0;
}
static void MainFormInit(FormPtr frmP)
{
TablePtr tableP;
UInt rowstbl,i;
tableP = GetObjectPtr(MainPatientTableTable);
rowstbl = TblGetNumberOfRows(tableP);
for (i = 0; i < rowstbl; i++) {
TblSetItemStyle(tableP, i, 0, checkboxTableItem);
TblSetItemStyle(tableP, i, 1, textTableItem);
TblSetItemStyle(tableP, i, 2, textTableItem);
}
for (i = 0; i < 3; i++)
TblSetColumnUsable(tableP, i, true);
TblSetLoadDataProcedure(tableP, 1, PatientBlock);
}
-------------------------------------------------------------
I appreciate for any advice.
