Re: NSRunAlertPanel()

So the main diffeence is that NSBeginAlertSheet creates a document =20
sheet instead of a new Panel, and that it uses selectors to determine =20=

what happens when the user clicks the buttons ?

Do you have an example of how you use an NSBeginAlertSheet ? I've =20
looked at the API, and it tells me:

void NSBeginAlertSheet(NSString *title, NSString *defaultButton, =20
NSString *alternateButton, NSString *otherButton, NSWindow *docWindow, =20=

id modalDelegate, SEL didEndSelector, SEL didDismissSelector, void =20
*contextInfo, NSString *msg, ...)

However, im not that confident in Cocoa (or C for that matter) and im =20=

not sure how to use selectors.

Thanks,
Joachim
