a file.

|
OS | mac, windows, linux |
Platforms | desktop |
Parameters | Name | Type | Description |
---|
prompt | | If you specify empty, no prompt appears.
|
defaultPath | | The name and location of the folder whose contents are listed when the
dialog box appears. If no defaultPath is specified, the dialog box lists
the contents of the last folder you used with a file dialog box.
|
types | | Use the types parameter to specify which files should appear and be
available for selection. Each set of types is a return-delimited list of
values of the form "tag|extensions|filetypes".
|
windowTitle | | The windowTitle, if specified, appears in the title bar of the dialog
box. If no windowTitle is given, the title bar is blank. (This parameter
has no effect on Mac OS systems, because Mac OS file dialog boxes don't
have a title bar.)

Example | answer file "Select a file to delete:"
answer files "Select the files you wish to process:"
answer file "Input:" with "/Macintosh HD/"
answer file (field "Prompt") with type "LiveCode Stacks|rev|RSTK"
answer files "Select the images you wish to view:" with type "JPEG Images|jpg|JPEG"
|
Values | Name | Type | Description |
---|
It | | The absolute file path of the file the user chose is placed in the it
variable. If the answer files form is used, a return-delimited list of
such paths is placed in the it variable. If the user cancels the
dialog, the it variable is set to empty.
|
The result | | If types are specified, the result function will return the tag of the
corresponding type selected from the supplied drop-down list.

Description | Use the answer file command when a handler needs the file path of
a file before continuing.
The dialog box displayed is the same one most programs use for the
"Open" command in the File menu.
Important: The answer file command does not open the file. It
only displays the dialog box and retrieves the path to the file the
user specifies.
If more than one type is specified, a drop-down list containing the tags
will be displayed allowing the user to select which types of files to
display. (This list is always displayed on Windows systems).
If the as sheet form is used, the dialog box appears as a sheet on OS X
systems. On other systems, the as sheet form has no effect and the
dialog box appears normally. Attempting to open a sheet from within
another sheet displays the second stack as a modal dialog box instead.
To give a dialog box a prompt when using the as sheet form a non-empty
title must be provided. This will cause the prompt to appear in the same
place it would if as sheet was not being used.
If the systemFileSelector property is set to false, LiveCode's
built-in dialog box is used instead of the operating system's
standard file dialog.
