Hey guys!  Hope all is well.  It's been a while since I was last here but today I am going to break down and finally ask this question that has been bugging me for the past year.

I have a project where I want to set the percision (number of decimal places) on a SpinBar to 4 (aka 0.0001).  No matter what I do I can't get it work.  It usually just gives me 3 places instead (0.001) or sometimes even resets it to zero places (0).

My end goal is to have the precision set at run time depending on the measuring units the user wants to use.  Thus if the user wants to enter the value in millimeters, the SpinBox will have a range of 0.000 to 0.400, or if using inches then the SpinBox will have a range of 0.0000 to 0.0160.

In my program I have tried setting the SpinBox directly with values for Max and Step without success.  Thinking it might be Gambas assuming I am using a different datatype, I tried the following:
But again, no success.  Any ideas?

I don't think you can do what you want with a SpinBar. So I suggest you create your own control. Try running the code below in a Graphical Application.

a range of 0.0000 to 0.0160.

By manipulating the "SpinBar" Control a bit, I got :? this:

Thanks guys.  I am going to try both of those to see which one I prefer.  

I have done very little work on custom controls so these techniques are little new to me.

cogier's solution, suggest you create ex novo your own Control, is the most expedient and most appropriate.
