Question

我需要在菜单栏应用中调整NSPopver的大小。这是我的方法：

override func mouseDragged(with event: NSEvent) {
    let appDelegate : AppDelegate = NSApplication.shared().delegate as! AppDelegate
    let originSize = appDelegate.popover.contentSize

    let currentLocation = NSWindow().mouseLocationOutsideOfEventStream

    let delta_x = NSWindow().mouseLocationOutsideOfEventStream.x - currentLocation.x
    let delta_y = NSWindow().mouseLocationOutsideOfEventStream.y - currentLocation.y

    let newWidth = originSize.width + delta_x
    let newHeight = originSize.height + delta_y

    appDelegate.popover.contentSize = NSSize(width: newWidth, height: newHeight)
}

问题：

NSPopover调整大小操作无法准确执行。
当光标悬停到NSPopover边框时，我希望光标变为箭头，我该如何实现呢？

编辑：

我试过NSPopOver & NSViewController - Drag to resize解决方案：

here is the effect

以下是转换为swift3版本的代码：

override func mouseDragged(with event: NSEvent) {
    var currentLocation = NSEvent.mouseLocation()

    var newOrigin   = currentLocation
    let screenFrame = NSScreen.main()?.frame

    newOrigin.x     = screenFrame!.size.width - currentLocation.x
    newOrigin.y     = screenFrame!.size.height - currentLocation.y

    // Don't let window get dragged up under the menu bar
    if newOrigin.x < 260 {
        newOrigin.x = 260
    }

    if newOrigin.y < 300 {
        newOrigin.y = 300
    }


    let appDelegate : AppDelegate = NSApplication.shared().delegate as! AppDelegate
    appDelegate.popover.contentSize = NSSize(width: newOrigin.x, height: newOrigin.y)

}

This is what I expect to achieve

Answer 1

PopoverResize，允许用户调整菜单栏NSPopover的大小。它还包括边缘的光标。

这对我有用：

override func mouseDragged(with event: NSEvent) {
    guard let appDelegate: AppDelegate = NSApplication.shared.delegate as? AppDelegate else { return }
    var size = appDelegate.statusItemManager.popover?.contentSize ?? CGSize.zero
    size.width += event.deltaX
    size.height += event.deltaY
    // Update popover size depend on your reference
    appDelegate.popover?.contentSize = size 
}

在菜单栏应用程序中拖动并调整我的NSPopover（swift）
