QPlainTextEdit 纯文本编辑器
|
|||
|
|
仅用于编辑纯文本的编辑器，性能比支持富文本的QTextEdit更佳
|
|||
|
|
官方文档：https://doc.qt.io/qtforpython/PySide6/QtWidgets/QPlainTextEdit.html
|
|||
|
|
继承自QAbstractScrollArea
|
|||
|
|
|
|||
|
|
与QTextEdit功能相似，但针对纯文本处理进行了优化，差异：
|
|||
|
|
QPlainTextEdit是一个简略版的类，使用QTextEdit和QTextDocument作为背后实现的技术支撑
|
|||
|
|
性能优于QTextEdit，主要是因为在文本文档中使用QPlainTextDocumentLayout简化文本布局
|
|||
|
|
纯文本文档布局不支持表格或嵌入框架，并使用逐行滚动的方式替换像素精确高度计算
|
|||
|
|
|
|||
|
|
两种构造函数，可以指定编辑器中的文本和父控件
