在appkit中禁用右键单击

盛年不重来，一日难再晨，及时当勉励，岁月不待人。这篇文章主要讲述在appkit中禁用右键单击相关的知识，希望能为你提供帮助。
我目前在mouseDrag函数中接受nextEvent

while true { guard let nextEvent = self.window?.nextEvent(matching: [.leftMouseDragged, .leftMouseUp, .rightMouseUp]) else { continue } switch nextEvent.type { case .leftMouseDragged: self.cursorUpdate(with: nextEvent) self.mouseDragged(with: nextEvent)case .rightMouseUp: continuedefault: self.mouseUp(with: nextEvent) return } }

而我只是试图在持续时间内禁用右键单击。但是，通过此实现，右键单击只是排队并在循环结束后调用。
如何禁用正确的点击注册？
答案尝试将.rightMouseDown和.rightMouseDragged添加到匹配的面具中。 .rightMouseDown事件使AppKit显示上下文菜单。

guard let nextEvent = self.window?.nextEvent(matching: [.leftMouseDragged, .leftMouseUp, .rightMouseDown, .rightMouseDragged, .rightMouseUp]) else { continue }

您也可以考虑切换到NSWindow.trackEvents(matching:timeout:mode:handler:)而不是编写自己的循环：

window.trackEvents(matching: [.leftMouseDragged, .leftMouseUp, .rightMouseDown, .rightMouseDragged, .rightMouseUp], timeout: NSEvent.foreverDuration, mode: .eventTrackingRunLoopMode) { (event, outStop) in guard let event = event else { return } switch event.type { case .rightMouseDown, .rightMouseDragged, .rightMouseUp: return case .leftMouseDragged: self.cursorUpdate(with: event) self.mouseDragged(with: event) case .leftMouseUp: self.mouseUp(with: event) outStop.pointee = true default: break } }

【在appkit中禁用右键单击】使用trackEvents让AppKit运行主运行循环，因此计时器和观察者可以继续射击（如果它们被安排用于.eventTrackingRunLoopMode）。
