B4J Question Such view exists ? slider (seekbar) to show decimal range

[peacemaker]

Hi, All

Do we have among B4X views some sider or seekbar (better if vertical + horizontal) that can show a decimal range, say -25.0, -24.9 ... 0.0 ... 24.9, 25.0 and allow to select\precisely adjust value being of small size (say 10%x of container)?

How about sliding between -250 and +250 and dividing the value by 10?

Yes, tried. Extra label is needed to show the result of calculation, but the main hardness is that small view cannot slide quite smoothly.

To have any chance of getting the precision you require, the view would need to have a width the same or larger as the amount of options. So -25 to 25 with a precision of 0.1 will require at least 501 pixels (1 for 0), and would still not be easy to control at pixel resolution.

I did something similar a long time ago but allowing dragging on a label, left / right in steps of 10 and up and down with an steps of 1. (you would need to scale it as you needed). You could also add precision by using a modifier key (control?) and then move in steps of 0.1. Visual feedback was limited to the label with the value. You could always add a seek bar showing an approximation of the value.

Another alternative could be to use a circular seek bar, which would probably take similar total area, but could be positioned in a square pane.

a circular seek bar

Yes, also tried already... And it seems, best way is to use ... just edittext views, decimally formatted.
