How to Change a button state when textFields become not empty

[Patrick CARDONA]

Hello,

I am working on an Internet Shortcuts Manager (aka SaveLink).


If they are not empty, the 'savebutton' should be enabled.


In the Header:

I associated the same action (statechange:) on my two fields ('name' and 'link'). But my button state does never change. Initial state is disabled and it remains in this state.

@interface SaveLink : NSObject
{
  IBOutlet id name;
  IBOutlet id link;
  IBOutlet id savebutton;
}

- (IBAction) statechange: (id)sender;
- (IBAction) save: (id)sender;
- (IBAction) reset: (id)sender;
- (IBAction) open:  (id)sender;

@end

In the class:

@implementation
 // (...)

- (IBAction) statechange: (id)sender
{
  // We retrieve values from textFileds outlets
  NSString *nameLink = [name stringValue];
  NSString *urlLink = [link stringValue];
  int lenName = [nameLink length];
  int lenLink = [urlLink length];
  if(lenName>0 && lenLink>0)
  {
    [savebutton setEnabled:YES];
  }
  else

  }
}

@end

{ [savebutton setEnabled:NO];

Any idea to make it work?

I joined the complete project. All was working as expected before I added this test stage. But I think it is needed as we should not want empty fields to perform the save action.
