Thanks for the link. I'm walking through the video now and hit a snag on
the "make a new window" part. This is with 8.2 NB. My NB11 has a similar
error (cannot access HelpCtx
class file for org.openide.util.HelpCtx not found)
error: cannot access Lookup
public class MyTopComponent extends TopComponent {
class file for org.openide.util.Lookup not found
warning: Supported source version 'RELEASE_6' from annotation processor
'org.netbeans.modules.openide.util.NbBundleProcessor' less than -source
'1.7'
error: cannot find symbol
setDisplayName("hello world");
symbol: method setDisplayName(String)
location: class MyTopComponent
C:\Program Files\NetBeans 8.2\harness\common.xml:225: Compile failed; see
the compiler error output for details.
BUILD FAILED (total time: 2 seconds)
If i remove the call to setDisplayName, i get an angry error message
warning: Supported source version 'RELEASE_6' from annotation processor
'org.netbeans.modules.openide.util.NbBundleProcessor' less than -source
'1.7'
