Hi All,
I'm very new to Cocoa programming, and can't seem to make the
NSTextFieldCell in an NSArray of NSTextFields that I want to be the one
selected when the application starts. I have tried
setInitialFirstResponder and makeFirstResponder without success so far.
If I do this:
[[displayMatrix window] makeFirstResponder:[[displayMatrix cells]
objectAtIndex:XDISPLAY]];
I get this error:
2002-09-01 14:31:34.825 SimpleRPN[6320] *** -[NSTextFieldCell
becomeFirstResponder]: selector not recognized
2002-09-01 14:31:34.906 SimpleRPN[6320] Exception raised during posting
of notification. Ignored. exception: *** -[NSTextFieldCell
becomeFirstResponder]: selector not recognized
If I use setInitialFirstResponder instead of makeFirstResponder, I
don't get the error, but the correct cell isn't active upon startup.
If I
[[displayMatrix window] makeFirstResponder: displayMatrix ];
I get no errors, but of course it doesn't select the matrix cell I want
of course, since I didn't tell it about which cell I wanted selected.
Can anyone help me out?
Thanks,
Rob
P.S. Here is a larger segment of my code if it helps:
@implementation Controller(ApplicationNotifications) //Delegates
-(void)applicationDidFinishLaunching:(NSNotification*)notification
{
//This is the initialization routine.
//The next line is our attempt to set the focus on the XDISPLAY.
// [[[displayMatrix cells] objectAtIndex:XDISPLAY]
setInitialFirstResponder:[[displayMatrix cells]
objectAtIndex:XDISPLAY]];
// [[[displayMatrix cells] objectAtIndex:XDISPLAY] selectText:self];
// NSWindow *win = [displayMatrix window];
// [win setInitialFirstResponder:[[displayMatrix cells]
objectAtIndex:XDISPLAY]];
[[displayMatrix window] makeFirstResponder:[[displayMatrix cells]
objectAtIndex:XDISPLAY]];
//[[displayMatrix window] makeFirstResponder: displayMatrix ];
[self clearAll:self];
}
