On a standard Cocoa Document based project, I want to add a new
window object/instance on startup (similar to adding a preference
panel, but a permanent offscreen window)
as an experiment, i did this below with a new onScreen window:
i get the new window to load alright on start up, but this disables
the old Document class somehow?, not even the old init is called
anymore??... I'm sure someone here can see quickly what i'm missing
in this experiment process...
(or give me a quick lesson in how Cocoa document apps startup)
------------------------------------------------------------------------------------
start with a new Document based cocoa project..
add this new window controller class, also add a xib file that is
nothing more than another window the same as the MyDocument.xib....
connect the new window to this new owner object
----------------------------------------
#import <Cocoa/Cocoa.h>
@interface MyDocument2 : NSWindowController
{
}
@end
----------------------------------------
#import "MyDocument2.h"
@implementation MyDocument2
- (id)init
{
self = [super initWithWindowNibName:@"MyDocument2"];
if (!self) { return nil; }
[self showWindow:nil];
return self;
}
- (NSString *)windowNibName
{
return @"MyDocument2";
}
@end
----------------------------------------
in the main menu nib, added a new "object" and make it the
"MyDocument2" object. so that this class loads on startup, and i get
the window on startup.
in the old "MyDocument" class, i changed this as an experiment, maybe
this is closer.
----------------------------------------
#import <Cocoa/Cocoa.h>
#import "MyDocumentController.h"
@interface MyDocument : NSDocument
{
}
@end
----------------------------------------
/*- (NSString *)windowNibName
{
return @"MyDocument";
}*/
- (void)makeWindowControllers
{
MyDocumentController *controller = [[MyDocumentController alloc]
initWithWindowNibName:@"MyDocument"];
[self addWindowController:controller];
[controller showWindow:nil]; //---------------- trying different
things in here......
}
----------------------------------------
and then I added this class as part of the experimenting...
----------------------------------------
#import <Cocoa/Cocoa.h>
@interface MyDocumentController : NSWindowController
{
}
@end
----------------------------------------
#import "MyDocumentController.h"
@implementation MyDocumentController
- (id)init
{
self = [super initWithWindowNibName:@"MyDocument"];
if (!self) { return nil; }
[self showWindow:nil];
return self;
}
- (NSString *)windowNibName
{
return @"MyDocument";
}
@end
----------------------------------------
nothing from the original document class is being executed anymore?
this project loads the "MyDocument2" object window correctly, but
then doesn't load the actual MyDocument object or it's window.
thanks for any help in advance on letting me know the fundamental
thing i'm missing in how Cocoa document based apps start up..
Jon.
