View Full Version : nsmatrix - calculator

Apr 7, 2009, 03:10 AM
Below is code for a basic ten button nsmatrix(of numbers), which should output the number to a text-field. The difficulty I am having is setting the ibaction (mytextoutput) to the matrix -- I can't do it in the IB. It only allows myMatrix to be set to the matrix, Do I need to do this programatically. I have tried to read about tags but not getting anywhere. The program runs without errors but when pushing buttons nothing happens. Thanks. Adam.

#import <Cocoa/Cocoa.h>

@interface AppController : NSObject {
IBOutlet NSTextField*myTextField;
IBOutlet NSMatrix*myMatrix;


#import "AppController.h"

@implementation AppController

[myTextField setStringValue:[[NSMatrix selectedCell]title]];

What do you mean you can't do it? When you control-drag from the matrix to your controller, do you see your myTextOutput: method show up in the list?
