NSGridView困难

nsview macos swift

user4992124 · 技术社区 · 6 年前

我用的是 NSGridView 在我的macOS应用程序的设置面板中。我是这样设置的:

class GeneralViewController: RootViewController {
    private var gridView: NSGridView?

    override func loadView() {
        super.loadView()

        let restaurantLabel = NSTextField()
        restaurantLabel.stringValue = "Restaurant"

        let restaurantButton = NSPopUpButton()
        restaurantButton.addItems(withTitles: ["A", "B", "C"])

        let updatesLabel = NSTextField()
        updatesLabel.stringValue = "Updates"
        updatesLabel.isEditable = false
        updatesLabel.isBordered = false
        updatesLabel.isBezeled = false

        let updatesButton = NSButton(checkboxWithTitle: "Automatically pull in updates from WordPress", target: nil, action: nil)

        let empty = NSGridCell.emptyContentView
        gridView = NSGridView(views: [
            [restaurantLabel, restaurantButton],
            [updatesLabel, updatesButton]
            ])
        gridView?.wantsLayer = true
        gridView?.layer?.backgroundColor = NSColor.red.cgColor
        gridView?.column(at: 0).xPlacement = .trailing
        gridView?.rowAlignment = .firstBaseline
        gridView?.setContentHuggingPriority(NSLayoutConstraint.Priority(rawValue: 600), for: .horizontal)
        gridView?.setContentHuggingPriority(NSLayoutConstraint.Priority(rawValue: 600), for: .vertical)

        view.addSubview(gridView!)
    }

    override func viewDidLayout() {
        super.viewDidLayout()

        gridView?.frame = NSRect(x: 0, y: 0, width: view.frame.size.width, height: view.frame.size.height)
    }
}

NSGridView视图 填充整个视图,但复选框实际上是关闭的。如图所示。

我该怎么解决?

如果将行对齐方式更改为 .lastBaseline 它会解决你的问题 NSButton NSTextField . 如果你想要更多的间隔(我猜这就是你所说的“我希望内容不能填满整个单元格”),你可以使用 columnSpacing 和 rowSpacing NSGridView . 如果还添加 NSGridCell.emptyContentView 围绕你的“真实”内容,你应该能够达到以下效果。

这是我建议更改后的新代码:

class GeneralViewController: RootViewController {
    private var gridView: NSGridView?

    override func loadView() {
        super.loadView()

        let restaurantLabel = NSTextField()
        restaurantLabel.stringValue = "Restaurant"

        let restaurantButton = NSPopUpButton()
        restaurantButton.addItems(withTitles: ["A", "B", "C"])

        let updatesLabel = NSTextField()
        updatesLabel.stringValue = "Updates"
        updatesLabel.isEditable = false
        updatesLabel.isBordered = false
        updatesLabel.isBezeled = false

        let updatesButton = NSButton(checkboxWithTitle: "Automatically pull in updates from WordPress", target: nil, action: nil)

        let empty = NSGridCell.emptyContentView
        gridView = NSGridView(views: [
            [empty],
            [empty, restaurantLabel, restaurantButton, empty],
            [empty, updatesLabel, updatesButton, empty],
            [empty],
            [empty]
        ])
        gridView?.wantsLayer = true
        gridView?.layer?.backgroundColor = NSColor.red.cgColor
        gridView?.column(at: 0).xPlacement = .trailing
        gridView?.rowAlignment = .lastBaseline
        gridView?.columnSpacing = 20
        gridView?.rowSpacing = 20
                gridView?.setContentHuggingPriority(NSLayoutConstraint.Priority(rawValue: 600), for: .horizontal)
        gridView?.setContentHuggingPriority(NSLayoutConstraint.Priority(rawValue: 600), for: .vertical)

        view.addSubview(gridView!)
    }

    override func viewDidLayout() {
        super.viewDidLayout()

        gridView?.frame = NSRect(x: 0, y: 0, width: view.frame.size.width, height: view.frame.size.height)
    }
}

NSGridView ,我建议使用 NSTableView .
