Suggestion for logarithmic scale for sliders
Just wanted to see if anyone would find it useful to be able to specify
a logarithmic scale for a slider so you could get values from 1 to
10,000,000 (for instance) without having a huge jump in value for each
pixel of mouse movement. So, the values could go: 1, 10, 100, 1000,
10000 instead of 1, 2, 3, 4, 5, 6, ...
Thoughts? Thanks.

Hi all,
I like all proposal here, and latest from Jason seems more general ...
as always please someone can add an issue (as improvement) in jira for
this ?
And now the real question ... for what release: 2.0.2 or 2.1 (I don't
think before the end of 2012) ?
Changes for this should be small so for me 2.0.2 is good (and we are
always in time to move to 2.1 if something strange will happen during
development of this feature).
Of course a related (minimal) small test application is welcome :-) ...
Bye,
Sandro

I would like to change my recommendation for LogSlider. Instead of specifying the actual values we should specify the power.
(updated) Logarithmic BXML: <LogSlider bxml:id="logslider" range="{start:0, end: 4, base:16}" power="3"/>
That way you do not have to check to see if the values provided are valid for the given base, and the "value" will be gained by returning the base to the power. And of course you still have access to the power setting.

I could see this very useful for graphical/scientific/mathematical/compSci applications. We should be able to specify the base as well.
Normal BXML: <Slider bxml:id="normalslider" range="{start:0, end:255}" value="0"/>
Logarithmic BXML: <LogSlider bxml:id="logslider" range="{start:0, end: 65536, base:16}" value="4096"/>
Code:
private Slider slider = null;
private LogSlider logslider = null;
slider = (Slider)namespace.get("slider");
slider = (logSlider)namespace.get("logslider ");
