本文介绍了如何绘制自定义窗口控件（关闭，最小化和缩放按钮）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我已经尝试绘制自定义NSButtons，但它似乎是我重新发明的轮子。有没有办法只是替换用于关闭，最小化和缩放按钮的默认图片？



几个应用程序已经做到了：




  • OSX 10.8的提醒应用程式（当窗口不重要时显示为深灰色，vs大多数显示为浅灰色）

  • 所有按钮完全自定义）



更多信息：



系统默认为 standardWindowButton：NSWindowCloseButton 。但是 setImage setter不会改变按钮的外观。

解决方案

编辑：自从我写这篇文章后， INAppStore 已实施用 INWindowButton 来做这个很好的方法。如果你正在寻找一个拖放解决方案检查那里，但下面的代码仍然会帮助你实现自己的。





所以我找不到一种方法来改变 standardWindowButton 。



注意：

有4种状态b
$ b

  • 窗口无效

  • 视窗启用 - 正常

  • 视窗启用 - 悬停

  • 视窗active-press



进入演练！



步骤1：隐藏预先存在的按钮 

  NSButton * windowButton = [self standardWindowButton：NSWindowCloseButton]; 
 [windowButton setHidden：YES]; 
 windowButton = [self standardWindowButton：NSWindowMiniaturizeButton]; 
 [windowButton setHidden：YES]; 
 windowButton = [self standardWindowButton：NSWindowZoomButton]; 
 [windowButton setHidden：YES];

步骤2：在Interface Builder中设置视图 b
$ b

您会注意到，悬停时，这些按钮都会更改为悬停状态，因此我们需要一个容器视图来拾取悬停。




  • 创建容器视图为54px宽x 16px高。

  • 创建3方形风格 NSButton





  • 设置按钮




    • 在属性检查器中，设置 属性为窗口主动 - 正常图像的每个按钮。

    • 将替代

    • 设置 code>键入到瞬间更改。

    • 每个按钮将标识符设置为关闭，最小化或缩放可以使用它来使NSButton子类更简单）



    步骤3：



    NSView。



    HMTrafficLightButtonsContainer.m

    在这里，我们将使用通知中心来通知按钮何时切换到悬停状态。 

      //告诉视图拾取悬停事件
      - （void）viewDidMoveToWindow {
     [self addTrackingRect： self bounds] 
     owner：self 
     userData：nil 
     assumeInside：NO]; 
    } 
     
     //当鼠标进入/退出时，我们发送这些通知
      - （void）mouseEntered：（NSEvent *）theEvent {
     [[NSNotificationCenter defaultCenter ] postNotificationName：@HMTrafficButtonMouseEnterobjects：self]; 
    } 
      - （void）mouseExited：（NSEvent *）theEvent {
     [[NSNotificationCenter defaultCenter] postNotificationName：@HMTrafficButtonMouseExitobject：self]; 
    }

    按钮：



    创建一个新文件，这个时候是子类NSButton。



    HMTrafficLightButton.m


    这是一个更好的解释。 

      @implementation HMTrafficLightButton {
     NSImage * inactive; 
     NSImage * active; 
     NSImage * hover; 
     NSImage * press; 
     BOOL activeState; 
     BOOL hoverState; 
     BOOL pressedState; 
    } 
     
      - （id）initWithCoder：（NSCoder *）aDecoder {
     self = [super initWithCoder：aDecoder]; 
     if（self）{
     [self setup]; 
    } 
     return self; 
    } 
     
      - （id）initWithFrame：（NSRect）frameRect {
     self = [super initWithFrame：frameRect]; 
     if（self）{
     [self setup]; 
    } 
     return self; 
    } 
     
      - （void）setup {
     //设置映像，我们使用标识符来选择要加载的映像
     active = [NSImage imageNamed：[NSString stringWithFormat：@window-button  - ％@  -  active，self.identifier]]; 
     hover = [NSImage imageNamed：[NSString stringWithFormat：@window-button  - ％@  -  hover，self.identifier]]; 
     press = [NSImage imageNamed：[NSString stringWithFormat：@window-button  - ％@  -  press，self.identifier]]; 
     inactive = [NSImage imageNamed：@window-button-all-inactive]; 
     
     //当调用
     if（[self.window isMainWindow]&& [NSApplication sharedApplication] isActive]时，检查窗口是否处于活动或非活动状态。 {
     [self setActiveState]; 
    } else {
     [self setInactiveState]; 
    } 
     
     //观察容器视图中的悬停通知
     //还监视窗口
     //成为/ resigns时的通知main 
     [[NSNotificationCenter defaultCenter] addObserver：self 
     selector：@selector（setActiveState）
     name：NSWindowDidBecomeMainNotification object：nil]; 
     [[NSNotificationCenter defaultCenter] addObserver：self 
    选择器：@selector（setInactiveState）
     name：NSWindowDidResignMainNotification object：nil]; 
     [[NSNotificationCenter defaultCenter] addObserver：self 
     selector：@selector（hoverIn）
     name：@HMTrafficButtonMouseEnter
     object：nil]; 
     [[NSNotificationCenter defaultCenter] addObserver：self 
     selector：@selector（hoverOut）
     name：@HMTrafficButtonMouseExit
     object：nil]; 
    } 
     
      - （void）mouseDown：（NSEvent *）theEvent {
     pressedState = YES; 
     hoverState = NO; 
     [super mouseDown：theEvent]; 
    } 
     
      - （void）mouseUp：（NSEvent *）theEvent {
     pressedState = NO; 
     hoverState = YES; 
     [super mouseUp：theEvent]; 
    } 
     
      - （void）setActiveState {
     activeState = YES; 
     if（hoverState）{
     [self setImage：hover]; 
    } else {
     [self setImage：active]; 
    } 
    } 
     
      - （void）setInactiveState {
     activeState = NO; 
     [self setImage：inactive]; 
    } 
     
      - （void）hoverIn {
     hoverState = YES; 
     [self setImage：hover]; 
    } 
     
      - （void）hoverOut {
     hoverState = NO; 
     if（activeState）{
     [self setImage：active]; 
    } else {
     [self setImage：inactive]; 
    } 
    } 
     
      - （void）dealloc {
     [[NSNotificationCenter defaultCenter] removeObserver：self]; 
    } 
     
     @end

    。



    步骤4：设置按钮操作



    这些方法，从视图控制器调用，与 standardWindowButton s相同。将它们链接到IB中的按钮。

       - （IBAction）clickCloseButton：（id）sender {
     [self。 view.window close]; 
    } 
      - （IBAction）clickMinimizeButton：（id）sender {
     [self.view.window miniaturize：sender]; 
    } 
      - （IBAction）clickZoomButton：（id）sender {
     [self.view.window zoom：sender]; 
    }

    第5步：将视图添加到窗口



    我有一个单独的xib和视图控制器设置专门为窗口控件。视图控制器称为HMWindowControlsController 

     （HMWindowControlsController *）windowControlsController = [[HMWindowControlsController alloc] initWithNibName：@WindowControls bundle：nil]; 
     NSView * windowControlsView = windowControlsController.view; 
     //设置窗口控件的位置，x是7 px，y将
     //取决于您的标题栏高度。 
     windowControlsView.frame = NSMakeRect（7.0，10.0，54.0，16.0）; 
     //添加到目标视图
     [targetView addSubview：windowControlsView];

    希望这有帮助。这是一个很长的帖子，如果你认为我犯了一个错误或留下了东西，请让我知道。


    I've made an attempt to draw custom NSButtons, but it seems I'm reinventing the wheel here. Is there a way to just replace the default images used for the close, minimize and zoom buttons?

    Several apps already do it:

    • OSX 10.8's Reminders app (they appear dark grey when the window is not key, vs most appear light grey)
    • Tweetbot (All buttons look totally custom)

    More info:

    I can generate the system defaults as such standardWindowButton:NSWindowCloseButton. But from there the setImage setter doesn't change the appearance of the buttons.

    解决方案

    Edit: Since I wrote this, INAppStore has implemented a pretty nice way to do this with INWindowButton. If you're looking for a drag and drop solution check there, but the code below will still help you implement your own.

    So I couldn't find a way to alter the standardWindowButtons. Here is a walkthrough of how I created my own buttons.

    Note: There are 4 states the buttons can be in

    • Window inactive
    • Window active - normal
    • Window active - hover
    • Window active - press

    On to the walkthrough!

    Step 1: Hide the pre-existing buttons

    NSButton *windowButton = [self standardWindowButton:NSWindowCloseButton];
[windowButton setHidden:YES];
windowButton = [self standardWindowButton:NSWindowMiniaturizeButton];
[windowButton setHidden:YES];
windowButton = [self standardWindowButton:NSWindowZoomButton];
[windowButton setHidden:YES];

    Step 2: Setup the view in Interface Builder

    You'll notice on hover the buttons all change to their hover state, so we need a container view to pick up the hover.

    • Create a container view to be 54px wide x 16px tall.
    • Create 3 Square style NSButtons, each 14px wide x 16px tall inside the container view.
    • Space out the buttons so there is are 6px gaps in-between.

    Setup the buttons

    • In the attributes inspector, set the Image property for each button to the window-active-normal image.
    • Set the Alternate image property to the window-active-press image.
    • Turn Bordered off.
    • Set the Type to Momentary Change.
    • For each button set the identifier to close,minimize or zoom (Below you'll see how you can use this to make the NSButton subclass simpler)

    Step 3: Subclass the container view & buttons

    Container:

    Create a new file, subclass NSView. Here we are going to use Notification Center to tell the buttons when they should switch to their hover state.

    HMTrafficLightButtonsContainer.m

    // Tells the view to pick up the hover event
- (void)viewDidMoveToWindow {
    [self addTrackingRect:[self bounds]
                    owner:self
                 userData:nil
             assumeInside:NO];
}

// When the mouse enters/exits we send out these notifications
- (void)mouseEntered:(NSEvent *)theEvent {
    [[NSNotificationCenter defaultCenter] postNotificationName:@"HMTrafficButtonMouseEnter" object:self];
}
- (void)mouseExited:(NSEvent *)theEvent {
    [[NSNotificationCenter defaultCenter] postNotificationName:@"HMTrafficButtonMouseExit" object:self];        
}

    Buttons:

    Create a new file, this time subclass NSButton. This one's a bit more to explain so I'll just post all the code.

    HMTrafficLightButton.m

    @implementation HMTrafficLightButton {
    NSImage *inactive;
    NSImage *active;
    NSImage *hover;
    NSImage *press;
    BOOL activeState;
    BOOL hoverState;
    BOOL pressedState;
}

-(id)initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];
    if (self) {        
        [self setup];
    }
    return self;
}

- (id)initWithFrame:(NSRect)frameRect {
    self = [super initWithFrame:frameRect];
    if (self) {
        [self setup];
    }
    return self;
}

- (void)setup {
    // Setup images, we use the identifier to chose which image to load
    active = [NSImage imageNamed:[NSString stringWithFormat:@"window-button-%@-active",self.identifier]];
    hover = [NSImage imageNamed:[NSString stringWithFormat:@"window-button-%@-hover",self.identifier]];
    press = [NSImage imageNamed:[NSString stringWithFormat:@"window-button-%@-press",self.identifier]];
    inactive = [NSImage imageNamed:@"window-button-all-inactive"];

    // Checks to see if window is active or inactive when the `init` is called
    if ([self.window isMainWindow] && [[NSApplication sharedApplication] isActive]) {
        [self setActiveState];
    } else {
        [self setInactiveState];
    }

    // Watch for hover notifications from the container view
    // Also watches for notifications for when the window
    // becomes/resigns main
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(setActiveState)
                                                 name:NSWindowDidBecomeMainNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(setInactiveState)
                                                 name:NSWindowDidResignMainNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(hoverIn)
                                                 name:@"HMTrafficButtonMouseEnter"
                                               object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(hoverOut)
                                                 name:@"HMTrafficButtonMouseExit"
                                               object:nil];
}

- (void)mouseDown:(NSEvent *)theEvent {
    pressedState = YES;
    hoverState = NO;
    [super mouseDown:theEvent];
}

- (void)mouseUp:(NSEvent *)theEvent {
    pressedState = NO;
    hoverState = YES;
    [super mouseUp:theEvent];
}

- (void)setActiveState {
    activeState = YES;
    if (hoverState) {
        [self setImage:hover];
    } else {
        [self setImage:active];
    }
}

- (void)setInactiveState {
    activeState = NO;
    [self setImage:inactive];
}

- (void)hoverIn {
    hoverState = YES;
    [self setImage:hover];
}

- (void)hoverOut {
    hoverState = NO;
    if (activeState) {
        [self setImage:active];
    } else {
        [self setImage:inactive];
    }
}

- (void)dealloc {
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

@end

    In IB set the Custom Class of the container view and all 3 buttons to their respective classes that we just created.

    Step 4: Set the button actions

    These methods, called from the view controller, are the same as the standardWindowButtons'. Link them to the buttons in IB.

    - (IBAction)clickCloseButton:(id)sender {
    [self.view.window close];
}
- (IBAction)clickMinimizeButton:(id)sender {
    [self.view.window miniaturize:sender];
}
- (IBAction)clickZoomButton:(id)sender {
    [self.view.window zoom:sender];
}

    Step 5: Add the view to the window

    I have a separate xib and view controller setup specifically for the window controls. The view controller is called HMWindowControlsController

    (HMWindowControlsController*) windowControlsController = [[HMWindowControlsController alloc] initWithNibName:@"WindowControls" bundle:nil];
NSView *windowControlsView = windowControlsController.view;
// Set the position of the window controls, the x is 7 px, the y will
// depend on your titlebar height.
windowControlsView.frame = NSMakeRect(7.0, 10.0, 54.0, 16.0);
// Add to target view
[targetView addSubview:windowControlsView];

    Hope this helps. This is a pretty lengthy post, if you think I've made a mistake or left something out please let me know.
