---------------------------------------------------------------------------------------------------------------
其他操作如下：
1、对字体的操作
MutableAttributeSet attr = new SimpleAttributeSet();
StyleConstants.setFontFamily(attr, family);
setCharacterAttributes(editor, attr, false);
family为字体
2、对字体大小的操作
MutableAttributeSet attr = new SimpleAttributeSet();
StyleConstants.setFontSize(attr, size);
setCharacterAttributes(editor, attr, false);
size为字号
3、是否是粗体的操作
StyledEditorKit kit = getStyledEditorKit(editor);
MutableAttributeSet attr = kit.getInputAttributes();
boolean bold = (StyleConstants.isBold(attr)) ? false : true;
SimpleAttributeSet sas = new SimpleAttributeSet();
StyleConstants.setBold(sas, bold);
setCharacterAttributes(editor, sas, false);
4、是否是斜体的操作
StyledEditorKit kit = getStyledEditorKit(editor);
MutableAttributeSet attr = kit.getInputAttributes();
boolean italic = (StyleConstants.isItalic(attr)) ? false : true;
SimpleAttributeSet sas = new SimpleAttributeSet();
StyleConstants.setItalic(sas, italic);
setCharacterAttributes(editor, sas, false);
5、是否有下划线的操作
StyledEditorKit kit = getStyledEditorKit(editor);
MutableAttributeSet attr = kit.getInputAttributes();
boolean underline = (StyleConstants.isUnderline(attr)) ? false : true;
SimpleAttributeSet sas = new SimpleAttributeSet();
StyleConstants.setUnderline(sas, underline);
setCharacterAttributes(editor, sas, false);
6、左中右对齐的处理
MutableAttributeSet attr = new SimpleAttributeSet();
StyleConstants.setAlignment(attr, a);
setParagraphAttributes(editor, attr, false);
public static final void setParagraphAttributes(JEditorPane editor,
AttributeSet attr, boolean replace) {
int p0 = editor.getSelectionStart();
int p1 = editor.getSelectionEnd();
StyledDocument doc = getStyledDocument(editor);
doc.setParagraphAttributes(p0, p1 - p0, attr, replace);
}
a:0：左，1：中，2：右
7、文本字体颜色的设置
MutableAttributeSet attr = new SimpleAttributeSet();
StyleConstants.setForeground(attr, fg);
setCharacterAttributes(editor, attr, false);
fg：为color
8、文本背景颜色的设置
MutableAttributeSet attr = new SimpleAttributeSet();
StyleConstants.setBackground(attr, bg);
setCharacterAttributes(editor, attr, false);
respond to和respond on 区别
1、意思不同
respond to是一个固定的搭配、词组。意思是回应，响应等。
例句：
The best way to respond to a flame is to ignore it.
回应谩骂性电子邮件的最好办法就是置之不理。
而respond on不是词组，只是碰巧在一起，意思是在......上作出反应。这里的on取决于后面的单词或指代事物等内容，和后面的内容有关，与respond无关。
例句：
The company said Wednesday it plans to
respond on the matter sometime early next year.
苹果公司上周三表示，计划在明年年初就此事作出回应。
2、读音不同
respond to读音：英 [rɪˈspɒnd tu] 美 [rɪˈspɑːnd tu]
respond on读音：英 [rɪˈspɒnd ɒn] 美 [rɪˈspɑːnd ɑːn]
扩展资料：
意思与之相似的还有：reply to和respond with
1、reply to
读音：英 [rɪˈplaɪ tu] 美 [rɪˈplaɪ tu]
v.答复；回答
例句：
The world community has been slow to respond to the crisis
国际社会对这次危机反应迟缓。
2、respond with
读音：英 [rɪˈspɒnd wɪð] 美 [rɪˈspɑːnd wɪð]
回复
例句：
Please respond with prices and technical specifications.
请响应价格和技术规格。
adorable是什么意思
adorable 英 [əˈdɔ:rəbəl,əˈdəʊr-] 美 [əˈdɔrəbəl,əˈdor-]adj.值得崇拜的，可敬重的，可爱的，讨人喜欢的[例句]We have three adorable children.我们有3个可爱的孩子。
