Daniele,

My suspicion is that the issue has nothing to do with whether or not you have a nib.

The code below won't work, because as far as I can tell, you never add the view to a window. A view needs to be in a window to receive events.

By the way, it's standard Cocoa naming convention to capitalize class names -- MyView rather than myView. It's a good idea to follow standard Cocoa naming conventions, especially when other people will read your code.

Hi,
I want to write an application without using a nib file.
I found same code that do this and it works, but I am not able to manage
event. For exactly I want to trap some event (tablet event) and manage this.
So, I write this code:


- main.m -------------------------------------
import <Cocoa/Cocoa.h>
#import "myView.h"

int main(int argc, const char *argv[])
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    NSWindow *window;
    myView *view;
    view = [[myView alloc] initWithFrame:NSMakeRect(0,100,200,200) ];

window = [[NSWindow alloc] initWithContentRect:NSMakeRect (50,100,200,300)
styleMask:NSTitledWindowMask | NSResizableWindowMask
backing:NSBackingStoreBuffered
defer:TRUE];



NSButton *button=[[NSButton alloc]initWithFrame:NSMakeRect (10,10,180,32) ];
[button setBezelStyle:NSRoundedBezelStyle];
[button setTitle:@"Quit"];
[button setTarget:NSApp];
[button setAction:@selector(terminate:)];


    [[window contentView] addSubview:button];

    [NSApplication sharedApplication];
    [window makeKeyAndOrderFront: nil];
    [pool release];

    [NSApp run];
    return 0;
}
 -----------------------------------
- myView.h ----------------------------------
#import <Cocoa/Cocoa.h>

@interface myView : NSView
{
}
- (id)initWithFrame:(NSRect)frame;
- (BOOL)acceptsFirstResponder;
- (void)tabletProximity:(NSEvent *)theEvent;
@end
 -----------------------------------

- myView.m ------------------------------------------
#import "myView.h"

@implementation myView
- (id)initWithFrame:(NSRect)frame {
    self = [super initWithFrame:frame];
    if (self) {
        printf("Parto..\n");
    }
    return self;
}

- (BOOL)acceptsFirstResponder
{
return YES;
}
- (void)tabletProximity:(NSEvent *)theEvent
{
printf("prossimita'\n");
if([theEvent isEnteringProximity])
{
printf("Entro\n");
printf("capabilityMask(%d)\n", [theEvent capabilityMask]);
printf("deviceID(%d)\n", [theEvent deviceID]);
printf("enterProximity(%d)\n", [theEvent isEnteringProximity]);
printf("pointerID(%d)\n", [theEvent pointingDeviceID]);
printf("pointerSerialNumber(%d)\n", [theEvent pointingDeviceSerialNumber]);
printf("pointerType(%d)\n", [theEvent pointingDeviceType]);
printf("systemTabletID(%d)\n", [theEvent systemTabletID]);
printf("tabletID(%d)\n", [theEvent tabletID]);
printf("uniqueID(%d)\n", [theEvent uniqueID]);
printf("vendorID(%d)\n", [theEvent vendorID]);
printf("vendorPointerType(%d)\n", [theEvent vendorPointingDeviceType]);
}
else
{
printf("Esco\n"); }


}
@end
--------------------------------------------------

This code draw a window with one button that, I press it, the program quit.
I see the window and button work, but the myView class seem not receive the windows events..


Have any idea for this?

Thanks
Daniele.
