hey all, another quick question..
I've been writing a wrapper around the accessibility api. Here's a
quick snippet:
- (AccessibilityOperationResult *) focusedApplicationRef {
if(![self isAccessibilityEnabled]) return [self getAPIDisabledOperationResult];
AccessibilityOperationResult *result =
[[[AccessibilityOperationResult alloc] init] autorelease];
CFTypeRef res = NULL;
AXUIElementRef sys = AXUIElementCreateSystemWide();
int rescode = AXUIElementCopyAttributeValue(sys,(CFStringRef)kAXFocusedApplicationAttribute,(CFTypeRef
*)&res);
CFRelease(sys);
[result setResultCode:rescode];
if([result wasSuccess]) {
[result setResult:res];
CFRelease(res);
}
return result;
}
I'm assuming that if a call to AXUIElementCopyAttributeValue fails, or
any similar function, that I don't need to release the "res" variable
- so I'm assuming that the accessibility api free's any memory that it
had allocated if a failure happens.
thanks much!
