如何在NSTableView中设置列边距？ [英] How do I set the column margins in an NSTableView?

问题描述

我想在我的NSTableView的列边距添加更多的填充（即在列的左侧和列文本之间更多的间隙）。

I would like to add more padding to the column margins in my NSTableView (ie. more gap between the left side of the column and the column text).

调用setIntercellSpacing为行的技巧，但它使列标题边距不受影响。任何人都可以提供解决方案？

Calling setIntercellSpacing does the trick for the rows, but it leaves the column heading margin unaffected. Can anyone offer a solution?

感谢

推荐答案

首先说，在表列标题单元格文本之间有边距有点奇怪，但这只是我的意见。

I'll first say it's a little weird to have margins between table column header cell text, but that's just my opinion.

没有API支持的方式来做这个确切的事情我所知。你可以通过请求列的标题单元格（它是NSTextFieldCell的子类），设置其属性字符串值（通过-setAttributedStringValue：）来实现效果。您可能还需要将-setAllowsEditingTextAttributes设置为YES，但是我不确定。

There's no API-supported way to do this exact thing as far as I know. You can probably achieve the effect by asking the column for its header cell (which is a subclass of NSTextFieldCell), setting its attributed string value ( via -setAttributedStringValue: ). You might have to also set -setAllowsEditingTextAttributes: to YES but I'm not sure.

另一种方法是子类化NSTableHeaderCell并覆盖-titleRectForBounds：复制矩形超级返回。然后，您必须通过-setHeaderCell：

The alternative is to subclass NSTableHeaderCell and override -titleRectForBounds: to pass a width-inset copy of the rectangle super returns. You'd then have to replace the columns' header cells via -setHeaderCell:.
