my question is in :
class QDoublePushButton(QPushButton):
doubleClicked = pyqtSignal()
clicked = pyqtSignal()
here
and
button = self.pushButton_16
button = QDoublePushButton(self)
button.doubleClicked.connect(self.on_doubleclick)
here.
I want it to say “**” when I press that
button once. (lineEdit).
When I double click I want him to say " . "
(lineEdit)
I created my double click class.
#this is double click class
class QDoublePushButton(QPushButton):
doubleClicked = pyqtSignal()
clicked = pyqtSignal()
def __init__(self, *args, **kwargs):
QPushButton.__init__(self, *args, **kwargs)
self.timer = QTimer()
self.timer.setSingleShot(True)
self.timer.timeout.connect(self.clicked.emit)
super().clicked.connect(self.checkDoubleClick)
@pyqtSlot()
def checkDoubleClick(self):
if self.timer.isActive():
self.doubleClicked.emit()
self.timer.stop()
else:
self.timer.start(250)
#here is calculator's class.
class QDoublePushButton(QPushButton):
doubleClicked = pyqtSignal()
clicked = pyqtSignal()
#here is calculator's class
button = self.pushButton_16
button = QDoublePushButton(self)
button.doubleClicked.connect(self.on_doubleclick)
I need to synchronize the top left button with the “**” button.
But I couldn’t did it.
Can u give me a hand ?
