Hi folks,
Does anyone know why calling FrmGetObjectIndex would cause POSE to throw
up an error dialog indicating "window.c, line:3826, Bad window"? It's
happening in the following utility function, which I'm using from other
places as well. As far as I can tell, the parameters are all ok, but
there must be something I'm missing. :-P
Here's the routine:
static FieldPtr SetFieldTextFromHandle(UInt16 fieldID, MemHandle txtH,
FormPtr frm, Boolean redraw)
{
MemHandle oldTxtH;
FieldPtr fldP;
UInt16 temp;
// get the field and the field's current text handle.
temp = FrmGetObjectIndex(frm, fieldID); // ERROR HAPPENS HERE
fldP = FrmGetObjectPtr(frm, temp);
ErrNonFatalDisplayIf(!fldP, "missing field");
oldTxtH = FldGetTextHandle(fldP);
// set the field's text to the new text.
FldSetTextHandle(fldP, txtH);
if ( redraw ) FldDrawField(fldP);
// free the handle AFTER we call FldSetTextHandle().
if (oldTxtH)
MemHandleFree(oldTxtH);
return fldP;
}
And here's where I'm calling it from:
static void EditReminderDateFormInit(FormPtr frmP)
{
Reminder r;
MemHandle h;
Char *numUnitsStr;
// Get Record from DB
h = DmQueryRecord( gDB, gCurrentRecord - 1 );
UnpackReminder( &r, MemHandleLock( h ) );
// put text into field
StrIToA( numUnitsStr, r.numUnits ); // it's stored as an Integer,
so we convert it to string for the field
gEditNumUnitsTextHandle = MemHandleNew( StrLen( numUnitsStr ) + 1 );
if ( !gEditNumUnitsTextHandle ) return;
StrCopy( MemHandleLock( gEditNumUnitsTextHandle ), numUnitsStr );
MemHandleUnlock( gEditNumUnitsTextHandle );
// Point text fields to text handles
SetFieldTextFromHandle( EditReminderDateNumUnitsField,
gEditNumUnitsTextHandle, frmP, false );
}
Thanks in advance for any help! I've been staring at this for a while,
and it's just got me stymied.
Sean
