I'm working through the XSViewController example project from
KATIDev and I came across this line:
[(ColorView*)[self view] setBackgroundColor:[[NSColor greenColor]
colorWithAlphaComponent:.5]];
and realized I don't understand (ColorView*). It looks like it's
declaring a pointer to an object, but it's followed by a method.
Could somebody tell me the name of the function (ColorView*) is
performing so I can look it up and figure it out?
That is casting the object returned from [self view] to a type of
"pointer to a ColorView object", that is, an instance of a ColorView.
Most likely, this is done to quiet a compiler warning about an object
(in this case, whatever [self view] is returning, not responding to -
setBackgroundColor:.
