3.2.2 List selectors
When the values in the list need to be named, only the current value is shown
(sometimes together with a short description) in a horizontal stripe with arrows at
both ends.
The arrows are buttons. Tap
to move left in the list or tap
to move right. You
need not confirm your selection. As soon as you leave the screen, the selected value
becomes effective.
3.2.3 Sliders
When a feature has several different unnamed (numeric) values, Touch & Go
Navigator will show sliders that look like analogue potentiometers to set the desired
value.
If the value limits are not displayed at the ends of the slider, the leftmost position
means the minimum value, while the rightmost position represents the maximum
value.
This control can be operated in two ways. Either drag the handle to move the slider
to its new position, or tap the slider where you want the handle to appear (the thumb
jumps there immediately). As with the list selectors, there is no need to confirm your
selection. As soon as you leave the screen, the selected value becomes effective.
3.2.4 Switches
When a function can only have two values (mainly Enabled and Disabled), a switch is
used. Unlike with list selectors, the horizontal line contains the name of the function
and not the actual status. There is a lamp on the left to show whether the function is
active or not.
When the lamp is dark (
), the function is not selected. When it is lit (
), the
function is enabled. The whole strip works as a button. Tap anywhere to toggle
between the enabled and disabled status.
