Method Detail

saveAs

public boolean saveAs(Document d)

Save the document to a user-specified location. Open a file chooser and forward the request to the document. Don't change the document's file object. Do nothing if the document is null. Return true if successul, otherwise false. File extension is checked and modified in the following way:

1. If the selected file filter is "*.*", then the file will be saved in .sml format. If the file name does not have a ".sml" extension, it is appended with ".sml".
2. If the selected file filter is ".gif" or ".sml", the corresponding file extension will be appended if the file name lacks the extension.
