Hi Nicola (Pero),
Hi All,
I wish first to thank You, Nicola, for the great tutorials You made.
They helped Me to understand and begin my learning pretty well.
Trying to play and understand the final code in the Tutorial 'First
Steps in GNUstep GUI Programming (2) : NSWindow, NSButton', I was
facing to some warnings and bugs. I think You should modify the final
code listing at page 9, in the '@implementation' section like this :
(1) In the method 'dealloc' :
- (void) dealloc
{
RELEASE (myWindow);
/* According to a warning while making the app */
[super dealloc];
}
(2) In the method 'createWindow' :
- (void) createWindow
{
...
myWindow = [NSWindow alloc];
/* Don't make a assignment of 'myWindow' again...
myWindow = */
/* So I kept only the message... */
[myWindow initWithContentRect: rect
styleMask: styleMask
backing: NSBackingStoreBuffered
defer: NO];
/* Here, the contentView was obviously missing : I added it... */
[myWindow setContentView: myButton];
...
}
I Hope this could be helpful for other Beginners like Me. ;-)
Regards,
