Question

为什么，当我按 Enter 时，keyPressEvent方法不能满足我的需要？它只是将光标移动到一个新行。

class TextArea(QTextEdit):
    def __init__(self, parent):
        super().__init__(parent=parent)
        self.setSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding)
        self.show()

    def SLOT_SendMsg(self):
        return lambda: self.get_and_send()

    def get_and_send(self):
        text = self.toPlainText()
        self.clear()
        get_connect(text)

    def keyPressEvent(self, event):
        if event.key() == QtCore.Qt.Key_Enter: 
            self.get_and_send()
        else:
            super().keyPressEvent(event)

Qt.Key_Enter是键盘上的Enter键：

Qt::Key_Return  0x01000004   
Qt::Key_Enter   0x01000005  Typically located on the keypad.

使用：

def keyPressEvent(self, qKeyEvent):
    print(qKeyEvent.key())
    if qKeyEvent.key() == QtCore.Qt.Key_Return: 
        print('Enter pressed')
    else:
        super().keyPressEvent(qKeyEvent)

为什么PyQt中的keyPress事件不能用于密钥Enter？
