You can share a frame with other developers in two ways:

• Add the frame to the Object Repository.
• Distribute the frame's unit (.pas) and form (.dfm or .xfm) files.

To add a frame to the Repository, open any project that includes the frame, right-click in the Form Designer, and choose Add to Repository. For more information, see Using the Object Repository. 

If you send a frame's unit and form files to other developers, they can open them and add them to the Tool palette. If the frame has other frames embedded in it, they will have to open it as part of a project.
