TConstantLine Compile Warning
lazarus / 55-TAChart

When I write code to create forms at runtime with a tchart component
and one or more TConstantLine series I get a compile warning for each
TconstatnLine series of :

Warning: Constructing a class "TConstantLine with abstract method
"IsEmpty"

I don't get this warning if I add the TConstantLine to the chart at
design time.

Do I need to be concerned about this, and if so, what do I need to do
to eliminate the warning?

I am using 1.0.8 and the tchart package that came with it.

Thanks!

Design time components are compiled as resources and constructed at
runtime through streaming, that's why you don't see the warning. Just
ignore it, it's safe as long as you don't call the respective method.
