Borderless NSButton turns gray when clicked

Question

I am making a little application with three NSButtons with an image set. These buttons have no border nor background. However, when I click a button it turns into a gray rectangle.

How can I fix this? Thanks.

Answer 1

Make your button type as NSMomentaryChangeButton.

[myBtn setButtonType:NSMomentaryChangeButton];

If you use NSMomentaryPushInButton then you may get gray rectangle over the button when click.

And what else? Could you add some more informatio. Check this metaSO question and Jon Skeet: Coding Blog on how to give a correct answer. – Clerk

Edited my answer. There is nothing more than this. – Extinguish

Doesn’t worked for me, instead @Sean’s answer is currently leading to the right direction. – Dorcia

FYI NSMomentaryChangeButton is now deprecated and replaced by NSButtonTypeMomentaryChange. – Fulminate

Answer 2

You should be able to adjust this by changing the state mask. To do so, check out the highlightsBy: and showsStateBy: properties of NSButtonCell - they are for setting the press effect and displaying the effect respectively. The applicable constants for these methods are in the NSCell reference page.

I was searching a long time for the flags. So here is the solution as an addendum (thx to Sean Rich very much for this help):[self.button.cell setShowsStateBy:NSPushInCellMask]; [self.button.cell setHighlightsBy:NSContentsCellMask]; if you change BOTH masks, only your graphics will be shown as specified in IB. – Burner

Answer 3

If you are using an NSBox, make sure your button inside of NSBox in the hierarchy. Then use 'momentary push in' as your button type. The button will dim when clicked but there will be no border.

When I used NSBox with NSButton on the same hierarchy level, I would see the border when clicked.
