我以编程方式创建了一个NSSlider,并在NSMenuItem中实现了它:
let menuVolumeSliderItem = NSMenuItem()
let menuVolumeSlider = NSSlider()
menuVolumeSlider.sliderType = NSSliderType.linear
menuVolumeSlider.isEnabled = true
menuVolumeSlider.isContinuous = true
menuVolumeSlider.action = #selector(AppDelegate.doSomething)
menuVolumeSlider.minValue = 0.0
menuVolumeSlider.maxValue = 1.0
menuVolumeSlider.floatValue = 0.5
menuVolumeSlider.frame.size.width = menu.size.width
menuVolumeSlider.frame.size.height = 20.0
menuVolumeSliderItem.view = menuVolumeSlider
menu.addItem(menuVolumeSliderItem)
基本上,它的工作就像一个魅力:
但我想要实现的结果是Slider,在Slider的左/右边缘有一个最小/最大图像,如下所示:
如何实现这样的NSMenuItem?
修改
我已经创建了一个自定义NSView:
let view = NSView()
view.frame.size.width = menu.size.width
view.frame.size.height = 25.0
...然后创建了一个NSImage ......
let img = NSImageView()
img.frame.size.width = 16.0
img.frame.size.height = 16.0
img.image = NSImage(named: "NSStatusAvailable")!
...并将menuVolumeSlider
和img
添加到我的自定义视图中:
view.addSubview(img)
view.addSubview(menuVolumeSlider)
menuVolumeSliderItem.view = view
menu.addItem(menuVolumeSliderItem)
......它有效!但有人可以给我一个提示如何改变子视图的位置吗?
答案 0 :(得分:1)
创建一个包含滑块和两个图像的NSView。然后将menuVolumeSliderItem.view设置为NSView。
