> Create implementation of NSAccessibilitySlider protocol > https://developer.apple.com/documentation/appkit/nsaccessibilityslider > > The implementation has the function performIncrement and performDecrement to > increase/decrease the value of slider using the VoiceOver. To implement this > functionality, I could think of following two ways. I have chosen the first > one here though it is more intrusive. > 1. Make the AccessibleJSlider class implement the AccessibleAction interface. > This makes AccessibleJSlider consistent with the AccessibleJSpinner class. It > is more clear and the logic to increase/decrease Slider value can be changed > easily. But this changes AccessibleJSlider class and will need a CSR. > 2. Get the current Accessible Value from the component and just > increment/decrement it in SliderAccessibility.m class itself and then set > the current accessible value fro there only. This will not need any changes > in AccessibleJSlider class, but this does not look correct way and I have not > used this. > > The changes can be easily tested by using a JSlider example, like the > following example.
