QTextEdit中不可编辑的文本

Question

Replaced text like this

QTextCursor cursor = mpEditor->textCursor();

cursor.beginEditBlock();

mpEditor->insertPlainText( inTxtReplace );

cursor.endEditBlock()

Visually everything is in order. But if you try to edit the text, it's nonsense, the characters are superimposed, you can not add anything. In what my mistakes?

Answer 1

Problem is that you are not reading documentation.

See QPlainTextEdit::readOnly .

Also if you using a text cursor use it modify document:

QTextCursor cursor = mpEditor->textCursor();
cursor.beginEditBlock();
cursor.select(QTextCursor::Document);
cursor.insertText(inTxtReplace);
cursor.endEditBlock()
