Re: [gtk-list] Double float for spinbutton.adjustment.value ?

[David Benson <daveb idealab com>]

I too have some could that would be radically simplified
with a double-based GtkAdjustment.

You see in my application there is a "rate" slider
which the user can manually fiddle with.
There is also a "synchronize rates" button that computes
the rate from other sources.

For this latter computation high-precision is needed.
And I think it cannot be needed in the former case,
since the ui widgets aren't really sufficient for entering
that accurate of a number.  I guess this is a rationale for
using gfloats in GtkAdjustment...

So in my application I keep a double outside the adjustment
and set a flag whether to use the double or the float.
A hack, but it works.
