The function prompt-for-files
presents the user with a dialog box similarly to prompt-for-file, but in which multiple filenames can be selected.
The arguments are as for prompt-for-file, except on Microsoft Windows where the default value of filters is:
("MS Word files" "*.doc"
"HTML files" "*.htm;*.html"
"Plain Text files" "*.txt;*.text"
"All files" "*.*")
On Cocoa and GTK+ the default value of filters is:
("Lisp Source Files" "*.lisp;*.lsp"
"Text Documents" "*.txt;*.text"
"All Files" "*.*")
which is the same default as for prompt-for-file.
filenames
is a list of filenames, or nil
if the user cancels the dialog.
successp
is a flag which is nil
if the dialog was cancelled, and t
otherwise.
filter-name is the name of the filter that was selected in the dialog.
If
continuation
is non-nil, then it must be a function with a lambda list that accepts three arguments. The
continuation
function is called with the values that would normally be returned by prompt-for-files
. On Cocoa, passing
continuation
causes the dialog to be made as a window-modal sheet and prompt-for-files
returns immediately, leaving the dialog on the screen. The with-dialog-results macro provides a convenient way to create a
continuation
function.
