1.1 隐藏NSWindow的标题栏
方法一: (1)重写NSWindow子类,继承NSWindow。 - (id)initWithContentRect:(NSRect)contentRect styleMask:(unsignedint)styleMask backing:(NSBackingStoreType)backingType defer:(BOOL)flag{ self = [super initWithContentRect:contentRect styleMask:NSBorderlessWindowMask backing:(NSBackingStoreType)backingType defer:YES]; return self; } (2)xib ViewController 上Window 继承子类 方法二: xib中直接取消title Bar 选中
1.2 设置窗口无边界
[self setStyleMask:NSBorderlessWindowMask];
1.3 设置窗口为透明
[self setOpaque:YES];
1.4 设置背景红色
[self setBackgroundColor:[NSColor redColor]];
1.5 设置为点击背景可以移动窗口
[self setMovableByWindowBackground:YES];
1.6 关闭当前window
[self.view.window close];
1.7 创建新的window
(1)创建子类WindowController,继承与NSindowController。 (2)创建新的Window self.windowController = [[WindowController alloc]initWithWindowNibName:@"WindowController"]; [self.windowController showWindow:self]; 一定要定义成全局的
1.8 NSWindow实现圆角
(1)子类化NSWindow,主要是重载了下面这个函数 - (id)initWithContentRect:(NSRect)contentRect styleMask:(NSUInteger)aStyle backing:(NSBackingStoreType)bufferingType defer:(BOOL)flag { self = [super initWithContentRect:contentRect styleMask:NSBorderlessWindowMask backing: NSBackingStoreBuffered defer:NO]; if (self != nil) { [self setOpaque:NO]; [self setBackgroundColor:[NSColor clearColor]]; } return self; } (2)子类化NSWindow的view,重载drawRect,其中的圆角半径和背景颜色 自己可以调整 - (void)drawRect:(NSRect)dirtyRect { [NSGraphicsContext saveGraphicsState]; NSRect rect = [self bounds]; NSBezierPath *path = [NSBezierPath bezierPathWithRoundedRect:rect xRadius:5 yRadius:5]; [path addClip]; [[NSColor controlColor] set]; NSRectFill(dirtyRect); [NSGraphicsContext restoreGraphicsState]; [super drawRect:dirtyRect]; }
1.9 监听window窗口大小
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(windowDidResize:) name:NSWindowDidResizeNotification object:nil]; - (void)windowDidResize:(NSNotification *)notification { //NSLog(@"notification %@",notification.object); NSWindow *window = notification.object; NSLog(@"window %@",NSStringFromRect(window.frame)); }
1.10 设置window不可拉伸
xib 中取消选择Resize。
