     `item3.addactionlistener(new actionlistener() {     @override     public void actionperformed(java.awt.event.actionevent e) {         //use fx thread open filechooser         platform.runlater(new runnable() {             @override             public void run() {                 filechooser filechooser = new filechooser();                 filechooser.settitle("create link");                 string startdirectory = system.getproperty("user.home") + file.separator + "pictures";                 filechooser.setinitialdirectory(new file(startdirectory));                 filechooser.extensionfilter extfilter = new filechooser.extensionfilter("jpeg files (*.jpg)", "*.jpg");                 filechooser.extensionfilter extfilter2 = new filechooser.extensionfilter("png files (*.png)", "*.png");                  filechooser.extensionfilter extfilter3 = new filechooser.extensionfilter("jpg files (*.jpeg)", "*.jpeg");                  filechooser.getextensionfilters().addall(extfilter,extfilter2, extfilter3);                  file imagefile = filechooser.showopendialog(stage);                 if(imagefile != null){                     image image = imageviewercontroller.getimage();                       try {                                        image = new image(imagefile.touri().tourl().toexternalform().tostring());                       int start = textarea.getselectionstart();                     int end = textarea.getselectionend();                        textarea.getdocument().remove(start, end);                       string newstring = "{\field{\*\fldinst hyperlink 'http://www.google.com/'}{\fldrslt http://www.google.com}}";                     textarea.getdocument().insertstring(start, newstring , null);                         textarea.addhyperlinklistener(new hyperlinklistener() {                                 @override                                 public void hyperlinkupdate(hyperlinkevent hle) {                                     if (hyperlinkevent.eventtype.activated.equals(hle.geteventtype())) {                                         system.out.println(hle.geturl());                                         desktop desktop = desktop.getdesktop();                                         try {                                              desktop.browse(hle.geturl().touri());                                         } catch (exception ex) {                                             ex.printstacktrace();                                         }                                     }                                 }                             });                          } catch (exception e1) {                         e1.printstacktrace();                     }                            }             }         });`

i think there various parts in question:

1. replace selected text in document:

get selected range with:

int start = editorpane.getselectionstart(); int end = editorpane.getselectionend();

replace text with:

editorpane.getdocument().remove(start,end); editorpane.getdocument().insertstring(start, newstring, null);

note: replace null actual attribute set if needed.

2. create rtf-formatted hyperlink. think this post has everything.

3. react hyperlink clicks: as explained in docs, must add hyperlinklistener editor pane open corresponding media. condition work editor kit generates hyperlinkevents when hyperlinks clicked. case html documents, since using 3rd party library, cannot confirm work same way...

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
