[squeak-dev] Double click on an data file

[Javier Reyes]

Hello !

I have created a Mac Application which stores certain information in files. These files are saved using Reference Stream. I have obviously provided a mechanism to read them back, but my problem comes if a user double clicks on the file icon at the Mac Osx operating system level. When that happens, the application opens with it's last image and the file is read as a text in a SystemWindow (Lots of fancy binary simbols!).  Is there a way I can control which method takes responsability of that process ?

All the best,
                            Javier

Use services.
You could made any exterrnal file was processed using your logic.
I add two examples of my own use, one for read objects saved to  disk the
other for my own "SqueakBooks"
