Disable NSButton without grayed image

Question

I want to disable the user interaction of NSButton . The only possible option seems to be setting isEnabled to false:

button.isEnabled = false

...but the problem is that it's giving a white shade to the image of my button. Is there any way to get rid of that shade?

Answer 1

You have to set the imageDimsWhenDisabled property of the corresponding button cell:

button.isEnabled = false
if let cell = button.cell as? NSButtonCell {
    cell.imageDimsWhenDisabled = false
}

Answer 2

One option would be instead of disabling it you can let it fire and handle it accordingly in code. such as do nothing when condition to disable applies.

Answer 3

As this answer says, override NSButton and return nil for hitTest(_:) .

If you want to toggle whether user interaction is enabled, create a custom variable and return super.hitTest(point) if you want the button to be enabled.

class CustomButton: NSButton {
    var isUserInteractionEnabled = true

    override func hitTest(_ point: NSPoint) -> NSView? {
        return isUserInteractionEnabled ? super.hitTest(point) : nil
    }
}
