如何将QTextCursor从QTextEdit移动到另一个QTextEdit？下面是我的代码：

self.textedit = QTextEdit(MainWindow)
self.textedit_2 = QTextEdit(MainWindow)
self.cursor = self.textedit.textCursor()
self.button.clicked.connect(self.moveCursor)

def moveCursor(self):
    self.textedit_2.setTextCursor(self.cursor)

Answer 1

光标与微件上的焦点相关，因此您需要先设置焦点

textedit_2.setFocus()

Answer 2

self.textedit = QTextEdit(MainWindow)
self.textedit_2 = QTextEdit(MainWindow)
self.cursor = self.textedit.textCursor()
self.button.clicked.connect(self.moveCursor)

def moveCursor(self):
    self.cursor = self.textedit_2.textCursor()
    self.textedit_2.setFocus()
    self.tetxtedit_2.setTextCursor(self.cursor)
