Hi everyone,
thx to Niklas and Daniel i got it running. Attached you find a Java
class which can be registered with XEnhancedMouseClickBroadcaster.
please have a look at it. i am looking forward to your feedback.
still some questions remain:
1. does it make sense to create a UNO package out of it wrapping some OO
basic macro around it to make an oxt extension out of it? Or how else
could this packaging thing be done?
2. anything about creating a custom mouse cursor? would be nice to see a
rubber/pencil as the mouse cursor.
thx
