History Manager
Go Up to Getting Started with RAD Studio
The History Manager lets you see and compare versions of a file, including multiple backup versions, saved local changes, and the buffer of unsaved changes for the active file. If the current file is under version control, all types of revisions are available in the History Manager.
The History Manager is displayed on the History tab, which is in the center of the IDE to the right of the Code tab. The History Manager contains the following tabbed pages:
| Page | Description |
|---|---|
|
Contents |
Displays the current and previous versions of the file. |
|
Info |
Displays all labels and comments for the active file. |
|
Diff |
Displays the differences between the selected versions of the file. |
The toolbar at the top of the History Manager contains the following buttons. Not all buttons are available on all pages of the History Manager.
Tip: The toolbar button functions are also available on the right-click context menus of the History Manager pages.
