L.S.,
I am trying to make a bitmap button the default button, but using the
function defaultButton results in an error message ('ok' is a
BitmapButton):
Couldn't match expected type `()'
with actual type `WXCore.CBitmapButton ()'
Expected type: Button ()
Actual type: BitmapButton ()
In the second argument of `(:=)', namely `ok'
In the expression: defaultButton := ok
Isn't BitmapButton supposed to inherit from Button?
I used the following as a workaround:
unsafeDefaultItem := objectCast ok
