I just wonder how to make a QLineEdit clickable because I want when the QLineEdit is clicked to clear the line's text.

  • It is quite a trivial thing to do. If all you need is clearing the line edit, reimplment `mousePressEvent` or `mouseReleaseEvent` in your custom class and clear the text. Or use event filters as in the link given by @Ian above. – Marcus Jan 31 '16 at 14:16
  • Use [setClearButtonEnabled](https://doc.qt.io/qt-5/qlineedit.html#clearButtonEnabled-prop). – ekhumoro Feb 20 '17 at 18:29

Try Below Code to make QLineEdit clickable :

class ClickableLabel(QLabel):

    clicked = pyqtSignal()
    def __init__(self,name, widget):
        super().__init__(name, widget)
    def mousePressEvent(self, QMouseEvent):
        self.clicked.emit()

Here is my 2 cents...

Definition :

    from PyQt5.QtWidgets import QLineEdit
    from PyQt5.QtCore import pyqtSlot
    from PyQt5.QtCore import pyqtSignal

    class cQLineEdit(QLineEdit):
        clicked= pyqtSignal()
        def __init__(self,widget):
            super().__init__(widget)
        def mousePressEvent(self,QMouseEvent):
            self.clicked.emit()

usage :

    self.cLE = cQLineEdit(self)
    self.cLE.setFixedWidth(20)
    self.cLE.move(10,200)
    self.cLE.clicked.connect(self.printText)

def printText(self):
    print("Yop,+++")

Hope this can help.
