Some of the older applications have a feature where when it is running a filedrop icon appears on the workbench. Using that you can open files in the app by drag 'n dropping them at the icon. It is quite useful especially if the app is opened on a different screen. If I recall correctly, CodeBench does that as well.
I'd like to add that feature to one of my applications, but I don't know the logic of how this is working nor have I managed to find any info anywhere.
Has anyone done that before? Do you guys have any info to share or any documentation to point me to?
