Brad,
The spinner example you're referring to is from Appendix B, the one that I referred to as "emulated" is from Appendix E. The one that you're referring to definitely does require the presence of the spinner dll since it uses the native spinner on whichever platform you're using. You should be able to put this spinner library in the same place as your swt-win32-xxxx dll and have it found. If you want to verify what your library search path is, write a snippet that prints the value of System.getProperty("java.library.path").

Grant,
I'm still getting this problem. My app already loads and accesses swt-win32-xxx.dll using the load library path, so I know that the problem isn't that it can't fine the swt dll. Here's the exception I get when I try to reference the spinner in my app:
[java] java.lang.UnsatisfiedLinkError: no spinner in java.library.path
[java] at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1491)
[java] at java.lang.Runtime.loadLibrary0(Runtime.java:788)
[java] at java.lang.System.loadLibrary(System.java:834)
[java] at org.netamie.reference.spi.swt.Spinner.<clinit>(Spinner.java:1
8)
Am I supposed to be referencing "spinner" or if using the swt dll am i supposed to be referencing some other library? I am wondering if the following code in the
Spinner class is the source of this problem:
static {
System.loadLibrary ("spinner");
}
Is this code unnecessary if you aren't using the spinner.dll (rather using the swt dll)?

Brad,
When I said that the Appendix E "all platforms" spinner was emulated, I meant that it's composed of existing widgets (a Text and two Buttons) as opposed to using a native spinner, so it doesn't depend upon getting spinner.dll compiled. These existing widgets still need to access their swt library though, so the problem you're likely seeing in this case is that swt-win32-xxxx.dll isn't being found.
I've attached a 13K zip with the following:
- The file with the text copying problem I mentioned had Spinner.java and SpinnerTest.java (Appendix B). I've attached the corrected versions, which will be posted shortly.
- I've noticed that copying the makefile.mak out of Appendix C will also have a problem if it comes out "double spaced" when you paste it ('echo' unexpected). I've attached the corrected version, which will be posted shortly.
- The compiled .dll
