Re: [platform-swt-dev] Improve Error messages from SWT

[Carolyn MacLeod <Carolyn_MacLeod@xxxxxxxxxx>]

Hi, Tom.
This sounds like a good idea.
Can you please open a bug report (Eclipse
- Platform - SWT), and you can assign it directly to me (Carolyn_MacLeod@xxxxxxxxxx).
It won't happen for 3.3, but we'll look
at improving error messages for 3.4.
Thanks!
Carolyn

Subject	[platform-swt-dev] Improve Error messages from SWT

Hi,

Just because I looked at a JFace-Bug-Report today I noticed that the
error message given from SWT could be improved e.g. take this bug report
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=186325). The SWT-Error
given doesn't tell anything about the cause of the problem. I think the
problem is a disposed font but if the error message would have been:

------------8<------------
java.lang.IllegalArgumentException: Argument not valid (Font passed is
disposed)
...
------------8<------------

This would make spotting the culprit much easier. My question is now do
you think it is worth the effort and I should log a bug and provide
better error messages using SWT.error(SWT.ERROR_INVALID_ARGUMENT,null,
"
(Font passed is disposed)").

Thanks

Tom
