Hi
I want to manipualte the filename of a NSSavePanel while it is
shown.
The events of the manipulation come from the accessoryview. I
want to
read it, modify it and set it back depending on events coming
from the
accessory view components.
How can I do that? The documentation says that "filename" should
be used
only at the end of the modal session and I understand the events
coming
from the controls inside the accessoryviews are during a modal
session.
Furthermore I found no provision on how to set the filename.
Any suggestions? The best solution would be portable to Mac, so I'd
prefer not to use internal variables/methods.
Thank you,
Riccardo
I think the Open/SavePanel has a delegate that can be used to filter/
manipulate the file selection.
What I am not sure is how ou make the SavePanel call the delegate and
update the file name if you press the button of an accessory view.
well, yes there are some delegate methods, but they do not allow me
to access and importantly set the filename.
What I want to achieve is the following:
You have a filename X.ext1
in the accessory view you select new settings which change the
filetype, accordingly .ext1 should change to ext2.
If you change settings again, ext2 should change to ext1 until you
save.
Getting the events from the accessory view is easy: I can connect
actions to it to a controller, it works. THe problem is the
information about the filename and its extension.
Is this in a document based application? If so, there is nothing you
need to do. NSDocument already sets up the accessory menu so that the
extension is switched when you change the document type. If you have
built up your own accessory menu, you can call the save panel's -
setRequiredFileType: method with the appropriate extension. Note that
the save panel will automatically add the correct extension to the
file name if it is missing when the user clicks OK (or when the name
has a different extension). However, it will not show the extension
automatically.
