How to make the button reset and change the name

[fbio]

When the buttons are pressed, the text should be changed. Or track the press. LineEdit, and she needs to clean up everything that method does. setFlat(True)♪

Try this:

import sys
from PyQt5.Qt import *
class DragButton(QPushButton):
def mousePressEvent(self, event):
    self.__mousePressPos = None
    self.__mouseMovePos = None
    if event.button() == Qt.LeftButton:
        self.__mousePressPos = event.globalPos()
        self.__mouseMovePos = event.pos()
    elif event.button() == Qt.RightButton:  
        lineEdit = QLineEdit(self)
        lineEdit.setMinimumHeight(self.size().height())
        lineEdit.editingFinished.connect(
          lambda le=lineEdit: self.editing_finished(le))
        lineEdit.show()
        lineEdit.setFocus()
    super(DragButton, self).mousePressEvent(event)

def mouseMoveEvent(self, event):
    if event.buttons() == Qt.LeftButton:
        delta = event.pos() - self.__mouseMovePos
        newPos = self.pos() + delta
        if self.parent():
            geo = self.rect().translated(newPos)
            parentRect = self.parent().rect()
            if geo.x() < 0:
                geo.moveLeft(0)
            elif geo.right() > parentRect.right():
                geo.moveRight(parentRect.right())
            if geo.y() < 0:
                geo.moveTop(0)
            elif geo.bottom() > parentRect.bottom():
                geo.moveBottom(parentRect.bottom())
            self.move(geo.topLeft())
        else:
            self.move(newPos)
    super(DragButton, self).mouseMoveEvent(event)
    
def editing_finished(self, le):
    self.setText(le.text())
    le.hide()

class MainWork(QMainWindow):

def init(self):

super().init()

self.centralWidget = QWidget()

self.setCentralWidget(self.centralWidget)
    self.push = DragButton("Кнопка", self)

if name == 'main':

w = MainWork()

w.resize(300, 300)

w.show()

sys.exit(app.exec_())
