QPlainTextEdit 文本字符格式
|
|||
|
|
可以为某个段落设置文本字符格式，如字体、下划线等
|
|||
|
|
本质上是调用了编辑器的光标的 QTextCursor.setCharFormat()等方法
|
|||
|
|
关于QTextCharFormat的更多用法见QtGu目录下对应目录
|
|||
|
|
|
|||
|
|
.setCurrentCharFormat(format: QTextCharFormat) 设置在插入新文本时使用的字符格式，如果已经选中了字符则直接应用
|
|||
|
|
.currentCharFormat() -> QTextCharFormat 返回插入新文本时使用的字符格式
|
|||
|
|
.mergeCurrentCharFormat(modifier: QTextCharFormat) 将modifier中指定的属性合并至当前字符格式，如果已经选中了字符则直接应用
