iTunes风格的NSWindow子类？

Question

是否有一个开源库可供Cocoa按照iTunes风格创建一个窗口？那就是窗口控件是垂直布局而不是水平布局：

我发现它节省空间，适用于不需要窗口标题的实用程序类型的应用程序。

这很快被黑客入侵的NSWindow代表应该让你开始：

//VerticalTrafficLightsWindowDelegate.h

#import <Cocoa/Cocoa.h>

@interface VerticalTrafficLightsWindowDelegate : NSObject <NSWindowDelegate> {
    NSWindow *window;
}

@property (assign) IBOutlet NSWindow *window;

- (void)verticalizeButtonsForWindow:(NSWindow *)aWindow;

@end

//VerticalTrafficLightsWindowDelegate.m

#import "VerticalTrafficLightsWindowDelegate.h"

@implementation VerticalTrafficLightsWindowDelegate

@synthesize window;

- (void)awakeFromNib {
    [self verticalizeButtonsForWindow:window];
}

- (void)windowDidResize:(NSNotification *)notification {
    [self verticalizeButtonsForWindow:window];
}

- (void)verticalizeButtonsForWindow:(NSWindow *)aWindow {
    NSArray *contentSuperViews = [[[aWindow contentView] superview] subviews];

    NSView *closeButton = [contentSuperViews objectAtIndex:0];
    NSRect closeButtonFrame = [closeButton frame];

    NSView *minimizeButton = [contentSuperViews objectAtIndex:2];
    NSRect minimizeButtonFrame = [minimizeButton frame];

    NSView *zoomButton = [contentSuperViews objectAtIndex:1];
    NSRect zoomButtonFrame = [zoomButton frame];

    [minimizeButton setFrame:NSMakeRect(closeButtonFrame.origin.x, closeButtonFrame.origin.y - 20.0, minimizeButtonFrame.size.width, minimizeButtonFrame.size.height)];
    [zoomButton setFrame:NSMakeRect(closeButtonFrame.origin.x, closeButtonFrame.origin.y - 40.0, zoomButtonFrame.size.width, zoomButtonFrame.size.height)];
}

@end

但是我得说，就像JeremyP一样，我只能希望Apple不会在OS X中更广泛地传播它。

您可能必须继承NSWindow，NSView的子类并自行绘制窗口和按钮。

哦，只是想补充说你在做自定义绘图时丢失了一些非常重要的细节。由于绘图是在主线程完成的，你的主线程可能忙于做一些重要的任务阻塞主线程执行一段时间，用户将无法移动窗口，他们按钮鼠标移动动画将无法正常工作

除非你在另一个线程中实现鼠标监听事件，否则在那里做绘图，锁定焦点......我的意思是 - 除非你真的认为这会让你的应用更好，所以不要打扰：）

基于@Regexident的新版macOS修改版。视图层次结构已更改为新的macOS UI，因此原始版本不起作用。修改后的代码如下（适用于macOS 10.13）：

- (void)verticalizeButtonsForWindow:(NSWindow *)aWindow {
    // New view hierarchy.
    NSView *titleBarContainerView = aWindow.contentView.superview.subviews[1];
    titleBarContainerView.frame = NSMakeRect(titleBarContainerView.frame.origin.x, titleBarContainerView.frame.origin.y - 60.0 + titleBarContainerView.frame.size.height, titleBarContainerView.frame.size.width, 60.0);
    NSView *titleBarView = titleBarContainerView.subviews[0];
    titleBarView.frame = NSMakeRect(0.0, 0.0, titleBarView.frame.size.width, 60.0);
    NSArray *titleBarSubviews = titleBarView.subviews;

    NSView *closeButton = [titleBarSubviews objectAtIndex:0];
    NSRect closeButtonFrame = [closeButton frame];

    NSView *minimizeButton = [titleBarSubviews objectAtIndex:2];
    NSRect minimizeButtonFrame = [minimizeButton frame];

    NSView *zoomButton = [titleBarSubviews objectAtIndex:1];
    NSRect zoomButtonFrame = [zoomButton frame];

    // Coordinate changed: add instead of minus.
    [minimizeButton setFrame:NSMakeRect(closeButtonFrame.origin.x, closeButtonFrame.origin.y + 20.0, minimizeButtonFrame.size.width, minimizeButtonFrame.size.height)];
    [zoomButton setFrame:NSMakeRect(closeButtonFrame.origin.x, closeButtonFrame.origin.y + 40.0, zoomButtonFrame.size.width, zoomButtonFrame.size.height)];
}

结果截图：
