java - Prevent typing in the same style in JTextPane -


forgive me possible misleading title, problem bit hard describe.

i'm trying create basic texteditor using jtextpane in java , i've run issue.

as know in texteditors can put caret/cursor behind piece of styled text (for example text bold) , can continue typing in same style (eg. append more bold characters).

luckely present default in jtextpane, want disable style. url-style coded (basicly 1 sets html.attribute.href attribute in style url).

so if put caret behind word (or piece of text) url, want ensure next characters added, not in url-style.

eg. think tinymce has behaviour:

  • you select text
  • click on insert url button
  • insert url
  • place cursor right after url , start typing again in normal style

is there way enforce behaviour in jtextpane?

i thinking this:

  • adding listener content changes in document
  • check if added characters placed right behind piece of text urlstyle
  • if case => remove "href" attribute style of characters

the code use setting url-style selected text can found below. "dot" , "mark" retrieved caret.

        simpleattributeset attr = new simpleattributeset(doc.getcharacterelement(dot).getattributes());         styleconstants.setunderline(attr, true);         styleconstants.setforeground(attr, color.blue);         attr.addattribute(html.attribute.href, url);         doc.setcharacterattributes((dot < mark) ? dot : mark, length, attr, true);

(note: able tell difference between normal "blue underlined" text , url, href attribute used url.)

ps: first question here, gave enough information. ;)

language: java, jdk 1.7

thanks in advance.

add caretlistener detect move , check whether current caret position needs style reset. if it's detected use

stylededitorkit's method 

public mutableattributeset getinputattributes()

here remove attributes don't need (url, blue, underline).
