About

Due to several problems, LCL components and ansistrings cannot be passed between a library (dll/so/dynlib) and an application (exe/app).

This interface provides a simple API between the library and the application to create LCL UI controls application-side, however controlled by dummies library-side.

LIBRARY EXAMPLE 1

procedure init; var myobj:TRHandle; begin 

 myobj:=RCreate(StrToRstr('TObject'));
 RSetStrProp(myobj,StrToRstr('MyStringProperty'),StrToRstr('Hello world!'));

end;

LIBRARY EXAMPLE 2

procedure init; var button:TRButton; begin 

 button:=TRButton.Create(RApplication);
 button.Caption:='Hello!';
 button.Parent:=RParent;

end;
