如何(以编程方式)设置主窗口的位置和大小? [英] How to set the position and size (programmatically) for the main window?

问题描述

我正在使用OS X的最新默认项目(10.11，Xcode 7.0).它使用情节提要板，层次结构如下:

I'm using the newest default project for OS X (10.11, Xcode 7.0). It uses storyboards and the hierarchy is as follows:

Window Controller -> View Controller

我想设置窗口的初始位置和框架尺寸.显然，用户可以更改它，但是我希望它以一些默认值开始.我尝试了子类化NSWindowController，但这没有效果.

I want to set the initial position and frame size for the window. Obviously the user can change that, but I want it to start with some defaults. I've tried subclassing NSWindowController, but that has no effect.

  class WindowController: NSWindowController {

     override func windowDidLoad() {
        super.windowDidLoad()

        guard let window = window else {
           return
        }

        let windowOriginPoint = CGPoint(x: 0, y: 0)
        let windowSize = CGSize(width: 800, height: 400)
        window.setFrame(NSRect(origin: windowOriginPoint, size: windowSize), display: true)

        print("windowDidLoad")
     }

  }

执行此操作的正确方法是什么?

What's the proper way of doing this?

推荐答案

我遇到了同样的问题.我通过将setFrame代码移到windowDidBecomeMain而不是windowDidLoad来解决了；如果将窗口手动移动并重新选择为主窗口，则会产生严重的副作用:拖动窗口时会跳转并立即返回到正确的位置.为了避免这种情况，我使用了一个补丁:在windowController中，我声明了一个

I faced the same problem. I solved it by moving the setFrame code inside windowDidBecomeMain instead of windowDidLoad; there is a bad side effect if the window has been moved manually and is reselected to become main: window jumps when dragged and immediately returns to the right position. To avoid it, I used a patch: In the windowController, I declare a

private var firstAppearance = true;

在windowDidBecomeMain中，我仅在firstAppearance上执行setFrame；然后将firstAppearance设置为false.

In the windowDidBecomeMain I do the setFrame only on firstAppearance; then I set firstAppearance to false.
