ask-user-for-directory

Arguments: &key (prompt "Select a folder.") (stream (selected-window-or-screen)) root dont-go-below-domain browse-include-files include-edit-box new-dialog-style

Displays a dialog where the user can select an existing directory (also known as a folder).

The newer function ask-user-for-new-or-existing-directory has more options than this one and works the same on all platforms, and so may be a better choice in most cases. On the other hand, on the Windows platform this function will show the dialog that is provided by Microsoft, with its native look and feel. On GTK, this function simply calls ask-user-for-new-or-existing-directory.

The chosen directory is returned as a pathname object. Note that the pathname of the directory is stored in a buffer and if the buffer is too small, an error will be signaled. The buffer size is determined by file-selection-buffer-size. The default size is large enough to hold at least 12 pathnames so this should not be a problem for this function, which returns one pathname only.

Note too that it is not possible to specify the initially-selected directory or which subdirectories are initially open in the hierarchy that is presented.

The arguments are:
