Reseting with ESC doesn't relly work well. |
|
HOME & END don't work as expected. Focus the handle, navigate several times with just the arrow. |
|
The inactive slider works with HOME & END |
|
I fixed the problem that the inactive Slider (with step set to '0') is affected by the keyboard shortcuts, but cannot reproduce the the first two described issues with ESC, HOME and END keys. |
-- onEnterDom() moved from Slider.js to SliderBase.js -- The Slider's handle is now focused via UI5Element getFocusDomRef() -- The private 'focus' property is removed as it is no longer used -- Keyboard interactions with inactive Slider (with step 0) are prevented

The Slider is now focusable, the element that gets the focus when
the component is active is the slider's handle. A new private property
'focused' is added.
The full keyboard handling specifications are implemented:
[TAB]Forward navigation-- On entering, move focus to the Slider.
-- If focus is on the Slider, move focus to the next element within the tab chain after the Slider.
[SHIFT] + [TAB]Backward navigation-- On entering, move focus to the Slider.
-- If focus is on the Slider, move focus to the previous element within the tab chain before the Slider.
[RIGHT], [UP], or [+]Increases the value of the Slider by a small increment.-- The Slider Thumb moves to the right/ up by the according value.
-- If the Slider Handle (Thumb) is at the maximum value position, do nothing.
[LEFT], [DOWN], or [-]Decreases the value of the Slider by a small increment-- The Slider Thumb moves to the left/ down by the according value.
-- If the Slider Thumb is at the minimum value position, do nothing.
[CTRL]+[RIGHT], [CTRL]+[UP], or [PAGE UP]Increases the value of the Slider by a large increment-- The Slider Thumb moves to the right/ up accordingly.
-- If the Slider Thumb is at the maximum value position, do nothing.
[CTRL]+[LEFT], [CTRL]+[DOWN], or [PAGE DOWN]Decreases the value of the Slider by a large increment.-- The Slider Thumb moves to the left/ down accordingly.
-- If the Slider Thumb is at the minimum value position, do nothing.
[HOME]Sets the minimum value. The Slider Thumb moves to the leftmost/ bottommost position.[END]Sets the maximum value. The Slider Thumb moves to the rightmost/ topmost position.[ESC]Sets the Slider back to the value which it had when it got the focus.
