One of the ideas I have for PastePass 1.0 is that the PassTool (to encrypt you password against your registered username) should get a GUI and do all what is need for your.

For that it needs to be able to write crypted pass into the Tooltype of an icon and to my suprise there isn't a proper API for that.

Tooltypes seem to be stored as a pointer to array of strings in struct DiskObject, so my guess is:

add: create an array of STRPTR 1 bigger than the one in the DiskObject, copy all existing entries into it, add new Tooltype at end, put that pointer into *do_ToolTypes and call PutDiskObject().
In order to leave no dangling memory I would than have to put the old pointer back in before calling FreeDiskObject()

change: all the same, just replacing that one string instead of the whole array.

Sounds like an awfully complicated and not really clean method....

That's the way it is. You may take a look at the Ambient source, how to set tooltypes...

Did that, got confused ;)

It is the only official way.

obtain diskobject
copy tooltype array to a bigger array
add own tooltype to the new array
terminate new array with NULL
swap pointer in diskobj
write icon to disk
swap pointer in diskobj back to the original
free disk object

You must not free or change any data on your own, so cloning is the only way to e.g. remove tooltypes in the same way.
