As you develop a 4D application, you will discover many capabilities that you did not notice when you started. You can even augment the standard version of 4D by adding plug-ins to your 4D development environment.
What is a plug-in and what can it do?
A plug-in is a piece of code, written in any language such as C or C++, that 4D launches at start up. It adds functionality to 4D and thus increases its capacity. A plug-in usually contains a set of routines given to the 4D developer. It can handle external areas and run external processes.
Where to find plug-ins?
You install plug-ins in the 4D environment by copying their files into the Plugins folder, at the same level as the Project folder.
Plug-ins are loaded by 4D when the application is launched so you will need to quit your 4D application before installing them. If a plug-in requires a specific license for use, it will be loaded but not available for use.
Plug-ins commands can be used as regular 4D commands in your 4D development. Plug-in commands appear in the Plug-ins page of the Explorer.
