Referencing class variables

[Bastiaan Olij]

The way I do it is by adding a "static" method to the window class. Omnis does not know the concept of static methods (unfortunately) so it's a hack but it works.


Simply add a method to your window:
getClassVar()
Quit method cClassVar


Now call this method with:
Do Code Method wMyWindow/getClassVar() Returns lvValue

And voila. You can call methods on your class with "do code method" even if there is no instance but obviously then only have access to the class vars.

Kindest Regards,

Thanks Peter, 
 
The notation works great for accessing the properties of the variable, but not the contents of the variable itself.
