Cocos2d is commonly thought of as a game development library and it has been treated as such in much of this book. However, Cocos2d is a robust solution for any 2D application. That said, draggable windows are a common element in many applications. In this example, we will create movable, collapsable menu windows.
Execute the following code:
#import "GameMenuWindow.h"
@implementation Ch5_MenuWindows
-(CCLayer*) runRecipe {
[super runRecipe];
//Initialization
windows = [[[NSMutableArray alloc] init] autorelease];
CCNode *windowContainer = [[CCNode alloc] init];
/* Create three menu windows with randomized positions */
GameMenuWindow *window1 = [GameMenuWindow windowWithTitle:@"Window 1" size:CGSizeMake(arc4random()%200+120,arc4random()%100+50)];
window1.position = ccp(arc4random()%100+150,arc4random()%140+100);
[windowContainer addChild...
