I have a NSSplitView in my app. Its divider position is fixed, the user is not able to drag the divider around. Now I am adding support for accessibility. When using VoiceOver, the user can select & drag the divider. That breaks my UI.
How can I tell VoiceOver, that it should ignore the divider?
I am using the new Accessibility Protocol available since OS X 10.10.
Setting splitView.isAccessibilityElement or splitView.isAccessibilityEnabled to no does not work.
Thanks for your help!
Ok, I asked a nice guy from the AppKit team at WWDC.
He told me that this is not possible at the moment - because I can not acces the divider within the splitView.
Explanation:
Disabling the accessibility support on a NSView, makes the particular view inaccessible, but not its sub view - which is the desired behavior normally
Since the divider is a subview of NSSplitView, this does not work.
Solution:
I ended up not using NSSplitView anymore because I don't need any of the class specific features. The dividers are fixed in my application.
Instead I used NSStackView to encapsulate my subviews - and it works perfectly. (Hide and show subviews)
