QLineEdit 默认回车可以打开对话框么 [复制链接]

我没有对QLineEdit 进行回车发送信号的预设，但是在debug后，却发现在lineedit中输入数据后回车会自动弹出加载图像的对话框，并且能够成功加载到我用Qbutton设定好的对话框内~查了很久都没有明白是什么原因，希望大家能够帮帮忙~

void QLineEdit::returnPressed ()   [signal]
This signal is emitted when the Return or Enter key is pressed. Note that if there is a validator() or inputMask() set on the line edit, the returnPressed() signal will only be emitted if the input follows the inputMask() and the validator() returns QValidator::Acceptable.

Thanks~~我去试下~
