Spinner - Min, Max values [message #479581] Tue, 11 August 2009 15:46 Go to next message

Hi,

I have a question concerning the min and max behaviour of the SWT Spinner
component.
In some cases, I have the same value for the min and max values. But this
is managed by the component as an error case :

Spinner.java => L 1090 : if (maximum <= minimum) return;

Does anyone knows why this has been done and if it is possible to allow
the min and max values to be equal in the next release of SWT ?

Thanks in advance,

Cédric

Note: when referring to code, you should give more context, including
the version of SWT and the method you are referencing. In the current
(3.5) version of Spinner.java, there is no line 1090.
Hopefully someone will explain why that limitation exits; if you want to
request a change you should do so via Bugzilla:
https://bugs.eclipse.org/bugs

Hope this helps,
Eric

Good.
I see that it was marked as a duplicate of another (old) bug report. I
suggest you make an attempt at fixing the problem and submitting a
patch, since bugs or feature requests with code patches tend to get more
attention than those without. Plus, it is a wonderful feeling to see
some code you wrote make it into the platform!

Eric
