So you will create a project and simply and that run-time package as a dependency to that project, so that it gets compiled into you project and used at run-time. As soon as you open the run-time package and compile it (NOT compile & install, just compile), then Lazarus knows about the package and it will appear as a option in the "dependency list" of other projects. design-time packages will add a new Property Editor or Component on the component palette of the IDE. It will register components that you can drop on a Form in the Form Designer. -- Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Run-time packages do not need to be installed. Just compile the package (Package->Open package file and in the following dialog just click compile). After that you can add your run-time package as a dependency to your project (for example via Project Inspector->add to Project->new requirement). hih R. -- A: Because it messes up the order in which people normally read text.
