问题
To start, there's an NSArrayController ("Servers") whose content is an array of "server" objects.
I also have an NSTableView with a column. The column is bound to Server's "arrangedObjects.status" property.
I use a custom NSValueConverter to make that status into an image for the column's dataCell which is an NSImageCell.
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.
Does the NSImageCell draw the images as faded? Is there something I can configure in IB that will draw them fully saturated?
回答1:
From Jim Correia on Cocoa-Dev:
"On 10.6, NSImageView will draw its content as dimmed when the control is disabled.
Your binding has “Conditionally Sets Enabled” turned on."
回答2:
You might have the image view cell or column's "enabled" property set to NO (or unchecked in IB). I believe this fades the displayed image.
