The Codolex installation will add a menu to the Delphi IDE.
The project explorer is the main window where you can see Codolex projects and the Codolex structure. You can create a new Codolex project or open an existing one from the project explorer, which is linked to your active Delphi project. When you compile your Delphi project, Codolex first generates the source code automatically, and adds the required paths to the search path of your Delphi project.
To make the integration work as smoothly as possible, it is best to 'dock' the project explorer within the Delphi IDE. When you save the layout, the project explorer remains in the same place, even if you restart Delphi.
