Swift & NSTableView - Simply select a row
提问by Isaiah
I'd like to programatically select a row in my NSTableView, with just one column.
我想以编程方式在我的 NSTableView 中选择一行,只有一列。
func selectColumnIndexes(_ indexes: NSIndexSet!,
byExtendingSelection extend: Bool)
I have been playing around with this, but I am not sure how to write "Select row #2".
Do I have to start with the variable connected to the @IBOutlet
of my Table View? I have to indicate it is about my NSTableView somehow.
我一直在玩这个,但我不知道如何写“选择第 2 行”。
我是否必须从连接到@IBOutlet
我的表视图的变量开始?我必须以某种方式表明它是关于我的 NSTableView 的。
Thanks!
谢谢!

I created an extension to make a little easier to do this. Also if you implemented a click action on the table view cell this will invoke it as well
我创建了一个扩展程序,以便更容易地做到这一点。此外,如果您在表格视图单元格上实现了点击操作,这也会调用它
extension NSTableView {
func selectRow(at index: Int) {
selectRowIndexes(.init(integer: index), byExtendingSelection: false)
if let action = action {
perform(action)
}
}
}
/// USAGE:
NSTableView().selectRow(at: 0)

@Isaiah 在 Swift 3.0 中的回答:
.selectRowIndexes(NSIndexSet(index: 0) as IndexSet, byExtendingSelection: false)

Okay, I've got it. It turned out to be
好的,我知道了。原来是
@IBOutlet weak var NoteTableView: NSTableView!
NoteTableView.selectRowIndexes(NSIndexSet(index: 0), byExtendingSelection: false)
I couldn't quite figure out the part with NSIndexSet
. I was fiddling around with init()
, which turned out to be unnecessary.
我无法完全弄清楚NSIndexSet
. 我正在摆弄init()
,结果证明这是不必要的。
