- Thread-topic: Newbie query re default buttons
As a Cocoa newbie (after years of Carbon), I am working my way through the
3rd edition of Hillegass' book. I finished his SpeakLine example then
thought I'd challenge myself by making the Speak button the default button
-- but failed.
I coded the following
*** AppController.h
@interface AppController : NSObject {
IBOutlet NSTextField *textField;
NSSpeechSynthesizer *speechSynth;
IBOutlet NSView *windView; <-- content view, added
IBOutlet NSButton *speakButton; <-- added
}
- (IBAction)sayIt:(id)sender;
- (IBAction)stopIt:(id)sender;
@end
*** added to AppController.m
- (void)awakeFromNib {
[[speakButton window] setDefaultButtonCell:[speakButton cell]];
// debugging
NSButtonCell *def = nil;
def = [[speakButton window] defaultButtonCell];
}
I made the connections in IB to both windView and speakButton and they look
OK (compared to those in Apple's BackgroundExporter sample code. I tried
using the content view as well as the button itself to get the window.
Neither works. My button is not blue or pulsing and the Return key does
nothing. The def variable *does* get the correct result (judging by self
variables). Using windView to get the window does not help.
Calling
[speakButton setKeyEquivalent:@"\r"];
did not work either.
Even though my code and the BackgroundExporter seem the same to me, I am
obviously missing something.
Any tips, from anyone?
TIA.
