Java默认荧光笔 [英] Java Default Highlighter

问题描述

我使用DefaultHightlighter.DefaultHightlighterPainter突出显示Java文本窗格中的文本. 我想删除所有突出显示(突出显示可能不止一个字符串)，并希望它返回已删除突出显示的字符串的位置，所以显然我不能使用 pseudoCodeTextPane.getHighlighter().removeHighlight(highlight);

Im using the DefaultHightlighter.DefaultHightlighterPainter to highlight text within a java text pane. I want to remove all highlights (there could be more than one string highlighted) and want it to return the locations of the strings where the highlight has been removed, so obviously I cant use pseudoCodeTextPane.getHighlighter().removeHighlight(highlight);

任何人都可以帮忙吗? 谢谢

Can anyone help? Thanks

推荐答案

类似的东西

 Highlighter.Highlight[] highlights = pseudoCodeTextPane.getHighlighter().getHighlights();
 int[] startOffsets = new int[highlights.length];
 int[] endOffsets = new int[highlights.length];
 for (int i = 0; i < highlights.length; ++i) {
     startOffsets[i] = highlights[i].getStartOffset();
     endOffsets[i] = highlights[i].getEndOffset();
 }
 pseudoCodeTextPane.getHighlighter().removeAllHighlights();
 // now do whatever processing you want to do with the highlight locations
