Question

I’m wondering if DWScript supports using a script method as an event handler for a control on a Delphi form. For example I want to link a TButton OnClick event to a method that exists in script.

I am able to do this with the RemObjects Delphi script engine by calling GetProcMethod which returns a TMethod object. I then use SetMethodProp to assign the script method to the OnClick event of a button.

procedure LinkMethod(SourceMethodName: String; Instance: TObject; ScriptMethodName: String);
var
  ScriptMethod: TMethod;
begin
  ScriptMethod := ScriptEngine.GetProcMethod(ScripMethodName);

  SetMethodProp(Instance, SourceMethodName, ScriptMethod);
end;

I would like to do this in DWScript instead of the Rem objects script engine as it does some other stuff that I need.

Answer 1

I decided to go with RemObjects instead. It was the easiest to use and does what I need.
