Type Function that takes a string, or null if no function is assigned. Example function err(errString) ( alert(errString); ) app.onError = err Application open() method app.open() app.open(file) Description The open() method opens a project. If the file parameter is null (i.e., if no argument is used) the user will be presented with a dialog to select and open a file.
