It seems like an application framework should offer full clipboard powers:
- Write various data types to the clipboard
- Query MIME types available on the clipboard for pasting
- Pasting various data types from the clipboard
- Querying if the current application was the one to fill the clipboard
- Clearing the clipboard
- Register for callbacks when the clipboard is changed
The first three would be more useful than the last three.
Imagine being able to paste formatted text into a JUCE TextEditor, or an image into a component, or audio data from a DAW into a sampler!
