im trying to create a very simple "test" cocoa application, without Xcode and IB, just to learn how to do it.
ive succeding in creating a window and adding a view, a textfield, and a button
i can move and resize the window using the mouse, and quit the application by clicking the button.

my problem is that i cant select the textview and type stuff in it. what happens is the application that was front application when i started my app(usually Terminal), still gets all key events, even after ive clicked on my apps window.

this is the code:

myView.h

Code:
#import <Cocoa/Cocoa.h>

@interface myView : NSView
{
}
@end

myView.m

Code:
#import "myView.h"

@implementation myView
- (void)drawRect:(NSRect)rect
{
    NSBezierPath *path = [NSBezierPath bezierPathWithRect:NSMakeRect(10,10,180,180)];
    [[NSColor greenColor] set];
    [path fill];
    NSLog(@"myView: drawRect:");
}
@end

main.m

Code:
#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];
    
    NSTextField *text=[[NSTextField alloc]initWithFrame:NSMakeRect(10,60,180,22) ];
    [text setStringValue:@"sample text"];
    
    NSButton *button=[[NSButton alloc]initWithFrame:NSMakeRect(10,10,180,32) ];
    [button setBezelStyle:NSRoundedBezelStyle];
    [button setTitle:@"Quit"];
    [button setTarget:NSApp];
    [button setAction:@selector(terminate:)];
    
    
    [window setTitle:@"test1"];
   
    [[window contentView] addSubview:view];
    [[window contentView] addSubview:text];
    [[window contentView] addSubview:button];
    
    [NSApplication sharedApplication];
    [window makeKeyAndOrderFront: nil];
    [pool release];
    
    [NSApp run];
    return 0;
}

tarball of the source files: test.tgz


this is how i compile and run

Code:
cc -framework Cocoa myView.m main.m
./a.out

any help would be greatly appreciated :)

Subclass NSWindow, and override the canBecomeKey method, like so:

- (BOOL)canBecomeKeyWindow
{
return YES;
}

That should fix it.

thanks!

ill give it a try right away

no difference with the subclass of NSWindow

i have a feeling the thing missing has something to do with bringing up the menubar or dock icon, because when i start my app, all that happens is that the window pops up, it still looks as Terminal is my front application(the terminal Menubar is still there)

Hrm. I know now what is happening, but I'm not sure how to fix it without Xcode. It seems like you should have LSUIElement (defined in Info.plist) set to something else. When it's set to 1, it behaves as it is now. That's how the joke app DeadScreen works.

You need to make it into a real application.

1. Create a folder called test.app from the commandline.
2. In the test.app directory, make a folder called Contents
3. In the Contents folder, make a folder called MacOS
4. In the MacOS folder, move your executable a.out file and name it test

Double click on test.app in the Finder and it will work.

Hope this helps,

are you sure that's the only way?

i dont really need the dock icon and menubar, being able to make the window active so that i could type in it, would suffice.

i thought maybe in a standard app, the NSApplicationMain() function runs a few functions that will read the NIB file and the Info.plist and setup the menubar and the dock icon, should be possible to do that manually just as well? but maybe its not

i think it would be really interested to know how, but i havent been able to find any example code that does this.


anyway guys, thanks for trying to help

i guess i didnt think that through very well, i tested you're suggestion with creating the test.app and it worked, so i guess that means NSApplicationMain() doesnt really do anything special
