Delegate doesn't compile

please have a look:
Code: Select all
Declare Function "NSTextView" - (NSRange)selectedRange
Declare Sub "NSTextView" - (void)setSelectedRange:(NSRange)charRange
Declare Sub "NSTextView" - (void)complete:(id)sender
Declare Function "NSString" - (NSString *)substringWithRange:(NSRange)aRange
Declare Sub "NSTextView" - (void)startSpeaking:(id)sender

Declare Class "NSInteger"

Declare Delegate "NSTextView" - (NSArray *)textView:(NSTextView *)textView completions:(NSArray *)words forPartialWordRange:(NSRange)charRange indexOfSelectedItem:(NSInteger *)index

IBOutlet theTextfield As NSTextField
' the music plays within the Events of the TextView - while processing thesse we can
' use the instance decoration at hand to appropriatly react to the Event
Event TextViewDidChangeSelection(theTextView As NSTextView)
  Dim theRange As Range
  Dim theString As NSString
  Dim theSubString As NSString
  Dim theLocation As Integer
  theRange = theTextView.selectedRange()
'  Log(theRange.Length)
'  Log(theRange.Location)
'  Log(theRange)

' Length only has a nonzero value if the user actually selects something 
  If(theRange.Length) Then
    theString = theTextView.Value
    theSubString = theString.substringWithRange(theRange)
    If (Contains(theSubString, "Huhn")) Then
      ' Notification.startSpeaking(Nil)
      ' if you like to append after the selected text just comment the following line out
      theRange.Location = theRange.Location + theRange.Length
'      theLocation=theRange.Location
'      ' unselect range by setting its length to zero
      theRange.Length = 0
'      theTextView.Insert(" du bist ein ")
'      theRange.Location=theLocation
'      theTextView.setSelectedRange(theRange)
'    Else
'      theTextfield.StringValue = ""
    End If 
 End If
End Event

Event TextDidEndEditing(Notification As id)
  Dim ra As Range

  Alert("End Editing",Notification)
End Event

'Event ShouldChangeText(ar As Array, Dummy As id)
'  Alert(ar)
'End Event

Event MouseDown(theEvent As NSEvent)
End Event

' if I use the KeyDown Event the character seems to be eleminated from the input buffer before
' the TextView actually sees it - it appears just as I have entered nothing i.e. pressed no key
' at all
Event KeyUp(theEvent As NSEvent)
End Event

Delegate textView(textView As NSTextView, words As Array, charRange As Range, index AsRef Integer) As NSArray
End Delegate

Event AwakeFromNib()
End Event

The compiler states
Code: Select all
/Users/HU/Desktop/ObjectiveBasic/ukTextView/Build/Release/ObjC/ In function 'NSArray* -[UKTextView textView:completions:forPartialWordRange:indexOfSelectedItem:](UKTextView*, objc_selector*, NSTextView*, NSArray*, NSRange, NSInteger*)':
/Users/HU/Desktop/ObjectiveBasic/ukTextView/Build/Release/ObjC/ error: call of overloaded 'NSOBJECT(NSInteger*&)' is ambiguous
compilation terminated due to -Wfatal-errors.

When replacing AsRef with As the problem persists.

if I replace (NSInteger *)index at the end of the delegate's signature with (NSInteger)index it works like it should - but I think this is quirky somehow.

happy new year for you as well. Enjoy your vacation - you deserve it.
I'll be patient and wait for your solution. I'll continue with the many features you have already implemented.

Kind regards
