Notification Manager ( old ) replacement
Posted by: fbcocoa.bw <fbcocoa.bw@...>
> Even though the old Notification Manager calls still work ( and there is no need to use pascal strings because they accept a pointer ), I’m hoping to find a modern replacement ( could be ’NS’ of ‘CF’ ). Searches of Xcode docs and the Carbon dev list did not find such support( looks like Eric Schlegel wrote a note about not having time to write a replacement ). I can find CFUserNotification ( bw wrote some nice examples in FB examples ) but a) I’m not sure if those work when the app is in the background and b) they don’t bounce the doc icon of the app. The NSNotification stuff doesn’t appear to cover this area on first reading but I could be wrong since it was only a cursory pass. Any thoughts?
I wonder if this will do it?

Notes:
- 'Compile as Objective-C'
- Run then click on another app
Request types:
- _kRUACritical bounces the dock icon until the app becomes active
- _kRUAInformational bounces the dock icon for one second
- Because this example puts up a modal dialog, the dock icon continues to bounce when _kRUAInformational
is used (see requestUserAttention: method discussion in NSApplication Class Reference)
