(send a-wx:media-edit load-file filename format) -> boolean
filename = null : string or null
format = wx:const-media-ff-guess : small integer
If filename is null, then the
internally stored filename will be used; if filename is "" or
if the internal name is unset or temporary, then the user will be
prompted for a name.
The possible values for format are:
- wx:const-media-ff-guess -- guess the format based on extension and/or contents
- wx:const-media-ff-std -- read in a standard file
- wx:const-media-ff-text -- read in a text file
- wx:const-media-ff-text-force-cr -- read in a text file; when writing, change automatic newlines (from word-wrapping)
into real carriage returns
- wx:const-media-ff-same -- read in whatever format was last loaded or saved
- wx:const-media-ff-copy -- read in whatever format was last loaded or saved, but do not change the modification flag or remember this filename
