I am using several NSButtonCell objects in an NSTableView. They are simple square buttons with custom images on them.
我在NSTableView中使用了几个NSButtonCell对象。它们是简单的方形按钮,上面有自定义图像。
These buttons draw properly when they are not highlighted: all that is visible is the image, and the rest of the button rectangle is transparent. However, when I click on them, the entire button rectangle is highlighted, inverting the background in the parts that were transparent.
这些按钮在未突出显示时正确绘制:所有可见的是图像,按钮矩形的其余部分是透明的。但是,当我单击它们时,整个按钮矩形会突出显示,反转透明部分的背景。
I would prefer to see the image drawn inverted, and the transparent parts remain transparent. How can this be done?
我宁愿看到倒置的图像,透明部分保持透明。如何才能做到这一点?

Try setting your cell's highlightsBy property to NSContentsCellMask. I think you'll have to do this in code (probably in awakeFromNib); I don't see a way to do it in IB alone.
尝试将单元格的highlightBy属性设置为NSContentsCellMask。我想你必须在代码中执行此操作(可能在awakeFromNib中);我没有看到单独使用IB的方法。

You can do it in Interface Builder too. I use "Square Button" so the button alters between two images (so the image is not inverted at all).
您也可以在Interface Builder中执行此操作。我使用“方形按钮”,因此按钮在两个图像之间改变(因此图像根本不会反转)。
Your buttons behaviour is probably set to "Momentary Light" or "Momentary Push In".
您的按钮行为可能设置为“瞬间光”或“瞬间推入”。
Set the Behaviour to "Momentary Change", and it should work.
将行为设置为“瞬间变化”,它应该工作。
