I have used ​OnUTF8KeyPress on Windows and Linux (GTK2 and QT) to enable
keyboard entry of the
degree symbol in place of the reverse dash with the following code:
Procedure TCoordinatePanel.DoOnUTF8KeyPress(Sender: TObject; Var UTF8Key:
TUTF8Char);
Begin
{ Substitute reverse dash for degree symbol. }
If UTF8Key=` Then
UTF8Key := #$C2#$B0; { UTF8 code for character. }
End;
However, on Mac this same code returns ?? in place of the degree symbol. This
is my first attempt at using Lazarus on the Mac,
can somebody explain what is happening here? I am using the latest official
Lazarus binary package 1.4.2 with the Carbon widgetset.
Thanks,
Paul Michell
