Hi
This is a problem that occurred a few months back in a project. I Never
actually used it in the project but it has bugged me ever since. I have
simplified the problem into a small example
There is a window with three NSTextFields and a button. The button is connected
to the doPaste action and the fields are outlets
Here is the code
-(IBAction)doPaste:(id)sender{
NSPasteboard *pb = [NSPasteboard generalPasteboard];
[pb declareTypes:[NSArray arrayWithObject:NSStringPboardType]
owner:self];
[pb setString:@"Field 1" forType:NSStringPboardType];
[textField1 becomeFirstResponder];
[self pasteIt];
[pb setString:@"Field 2" forType:NSStringPboardType];
[textField2 becomeFirstResponder];
[self pasteIt];
[pb setString:@"Field 3" forType:NSStringPboardType];
[textField3 becomeFirstResponder];
[self pasteIt];
}
-(void)pasteIt{
CGEventSourceRef sourceRef =
CGEventSourceCreate(kCGEventSourceStateCombinedSessionState);
if (!sourceRef)
{
NSLog(@"No event source");
return;
}
//9 = "v"
CGEventRef eventDown = CGEventCreateKeyboardEvent(sourceRef,
(CGKeyCode)9, true);
CGEventSetFlags(eventDown, kCGEventFlagMaskCommand);
CGEventRef eventUp = CGEventCreateKeyboardEvent(sourceRef,
(CGKeyCode)9, false);
CGEventPost(kCGHIDEventTap, eventDown);
CGEventPost(kCGHIDEventTap, eventUp);
CFRelease(eventDown);
CFRelease(eventUp);
CFRelease(sourceRef);
}
I expected that each of the fields would have their respective text pasted into
them. What actually happens is that the last field gets three copies of it's
text, Field 3, pasted into it. The other two fields are blank.
Can anybody explain why that should happen.
