There are a number of ways to quickly open a sandbox in MacCVSClient from the finder.

Double-Click

• Double click the CVS sandbox info bundle in the finder and the folder containing that sandbox info bundle will be opened.

Drag-Drop

• Drag-dropping a sandbox folder onto the MacCVSClient application icon will open it.
• Drag-dropping a file (in a sandbox folder) onto the MacCVSClient application will open the file's surrounding folder and then select the file.

Some Details

If a content item (sub-folder or file) of an already open sandbox is attempted to be opened, the item is selected in the open sandbox.

If a parent folder (or a file living in it) of an already open sandbox is attempted to be opened, the already open sandbox folder is closed and it's contents (including diffs, logs, annotations, etc.) is brought over into the newly opened parent sandbox.

If a file (or folder) is attempted to be opened which would not be visible due to its current sandbox filter settings (menu "Special/Filter File Settings"), this item will become temporarily visible in the sandbox window. Temporarily here means until the next CVS operation, Filter On/Filter Off command, or switching away from and back to MacCVSClient (refresh).

If a file (or folder) is attempted to be opened which would not be visible because parent folders are not expanded (but collapsed instead), all parent folders are expanded so the file (or folder) becomes visible.
