为什么我的图像在我的NSTableView淡出？ [英] Why are my images in my NSTableView faded out?

问题描述

首先，有一个 NSArrayController （Servers），其内容是一个服务器对象的数组。

To start, there's an NSArrayController ("Servers") whose content is an array of "server" objects.

我也有一个 NSTableView 和一个列。该列绑定到服务器的arrangedObjects.status属性。

I also have an NSTableView with a column. The column is bound to Server's "arrangedObjects.status" property.

我使用自定义 NSValueConverter 成为列的 dataCell 的图像，该列是 NSImageCell 。

I use a custom NSValueConverter to make that status into an image for the column's dataCell which is an NSImageCell.

我不明白的是为什么在列中显示的图像是正确的，但是一直淡出。只是为了测试，我有相同的图像在表视图之外进行比较，它绘制精细。图片中的颜色不是半透明的。

What I don't understand is why the images that show up in the column are correct, but consistently faded out. Just to test, I have the same image outside the table view for comparison and it draws fine. The colors in the images are not semi-transparent.

NSImageCell 是否将图片绘制为褪色？

Does the NSImageCell draw the images as faded? Is there something I can configure in IB that will draw them fully saturated?

推荐答案

来自Jim Correia的Cocoa-Dev：

From Jim Correia on Cocoa-Dev:

在10.6中，NSImageView将在禁用控件时将其内容绘制为灰色。

"On 10.6, NSImageView will draw its content as dimmed when the control is disabled.

设置已启用已打开。
