谢谢

你需要一个窗口的图像作为你的动画的内容,所以我要做的是订购窗口(也可能使它成为关键窗口,使它看起来很集中),但要把它放好在屏幕外,所以用户没有看到它.然后使用CGWindowListCreateImage抓取窗口的屏幕截图.现在,您将拥有创建动画所需的一切.

动画完成后,只需将实际窗口排在透明窗口的顶部,然后删除透明窗口.使数学正确,以便动画和真实窗口中的窗口图像有点棘手,但它绝对可行.

-(void)cursorUpdate:(NSEvent *)theEvent {
    [[NSCursor resizeLeftCursor] set];
}

我为NSWindow实现自定义resize,它使用NSBorderlessWindowMask.并希望使用本机Lion的两个箭头游标.但是这种类型的游标在NSCursor API中不存在.

我能从代码中以某种方式获得这样的原生游标吗？
或者也许我必须手工重绘(不是一个好主意)？

/System/Library/Frameworks/WebKit.framework/Versions/Current/Frameworks/WebCore.framework/Resources/

…例如,文件“northWestSouthEastResizeCursor.png”.

我使用子类NSView作为我的NsstatusItem的自定义视图,并且右键和左键单击执行不同的函数：

- (void)mouseDown:(NSEvent *)theEvent{
    [super mouseDown:theEvent];
    if ([theEvent modifierFlags] & NSCommandKeyMask){
        [self.target performSelectorOnMainThread:self.rightAction withObject:nil waitUntilDone:NO];
    }else{
        [self.target performSelectorOnMainThread:self.action withObject:nil waitUntilDone:NO];
    }
}

- (void)rightMouseDown:(NSEvent *)theEvent{
    [super rightMouseDown:theEvent];
    [self.target performSelectorOnMainThread:self.rightAction withObject:nil waitUntilDone:NO];
}

如何在右键单击时显示菜单,与标准NsstatusItem在左键单击时的操作方式相同？

这是我的代码的重要部分：

- (void)showMenu{
    // check if we are showing the highlighted state of the custom status item view
    if(self.statusItemView.clicked){
        // show the right click menu
        [self.statusItem popUpStatusItemmenu:self.rightClickMenu];
    }
}

// menu delegate method to unhighlight the custom status bar item view
- (void)menuDidClose:(NSMenu *)menu{ 
    [self.statusItemView setHighlightState:NO];
}

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification{
    // setup custom view that implements mouseDown: and rightMouseDown:
    self.statusItemView = [[IsstatusItemView alloc] init];
    self.statusItemView.image = [NSImage imageNamed:@"menu.png"];
    self.statusItemView.alternateImage = [NSImage imageNamed:@"menu_alt.png"];    
    self.statusItemView.target = self;
    self.statusItemView.action = @selector(mainAction);
    self.statusItemView.rightAction = @selector(showMenu);

    // set menu delegate
    [self.rightClickMenu setDelegate:self];

    // use the custom view in the status bar item
    self.statusItem = [[NsstatusBar systemStatusBar] statusItemWithLength:NSSquareStatusItemLength];
    [self.statusItem setView:self.statusItemView];
}

以下是自定义视图的实现：

@implementation IsstatusItemView

@synthesize image = _image;
@synthesize alternateImage = _alternateImage;
@synthesize clicked = _clicked;
@synthesize action = _action;
@synthesize rightAction = _rightAction;
@synthesize target = _target;

- (void)setHighlightState:(BOOL)state{
    if(self.clicked != state){
        self.clicked = state;
        [self setNeedsdisplay:YES];
    }
}

- (void)drawImage:(NSImage *)aimage centeredInRect:(NSRect)aRect{
    NSRect imageRect = NSMakeRect((CGFloat)round(aRect.size.width*0.5f-aimage.size.width*0.5f),(CGFloat)round(aRect.size.height*0.5f-aimage.size.height*0.5f),aimage.size.width,aimage.size.height);
    [aimage drawInRect:imageRect fromrect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0f];
}

- (void)drawRect:(NSRect)rect{
    if(self.clicked){
        [[NSColor selectedMenuItemColor] set];
        NSRectFill(rect);        
        if(self.alternateImage){
            [self drawImage:self.alternateImage centeredInRect:rect];
        }else if(self.image){
            [self drawImage:self.image centeredInRect:rect];
        }
    }else if(self.image){
        [self drawImage:self.image centeredInRect:rect];
    }
}

- (void)mouseDown:(NSEvent *)theEvent{
    [super mouseDown:theEvent];
    [self setHighlightState:!self.clicked];
    if ([theEvent modifierFlags] & NSCommandKeyMask){
        [self.target performSelectorOnMainThread:self.rightAction withObject:nil waitUntilDone:NO];
    }else{
        [self.target performSelectorOnMainThread:self.action withObject:nil waitUntilDone:NO];
    }
}

- (void)rightMouseDown:(NSEvent *)theEvent{
    [super rightMouseDown:theEvent];
    [self setHighlightState:!self.clicked];
    [self.target performSelectorOnMainThread:self.rightAction withObject:nil waitUntilDone:NO];
}

- (void)dealloc{
    self.target = nil;
    self.action = nil;
    self.rightAction = nil;
    [super dealloc];
}
