How To Create A Timer In Pyqt
I have a question that may be simple but i hav failed to get it solved I want to create a timer in pyqt using QTimeEdit with default time starting at 00:00:00 and increasing every
Solution 1:
{yout time}.addSecs(1)
does not change time, but returns the changed time. Your must be use {yout time} = {yout time}.addSecs(1)
import sys
from PyQt5 import QtCore
def timerEvent():
global time
time = time.addSecs(1)
print(time.toString("hh:mm:ss"))
app = QtCore.QCoreApplication(sys.argv)
timer = QtCore.QTimer()
time = QtCore.QTime(0, 0, 0)
timer.timeout.connect(timerEvent)
timer.start(1000)
sys.exit(app.exec_())
Output:
00:00:0100:00:0200:00:0300:00:0400:00:0500:00:0600:00:0700:00:0800:00:0900:00:1000:00:1100:00:12
#Solution 2:
I can't test it but I think you need
self.curr_time = QtCore.QTime(00,00,00)
self.timer = QtCore.QTimer()
self.timer.timeout.connect(self.time)
self.timer.start(1000)
deftime(self):
self.curr_time = self.curr_time.addSecs()
self.upTime.setTime(self.curr_time))
You have to create QtCore.QTime(00,00,00)
only once and later increase its value in time()
.
Now you always use QtCore.QTime(00,00,00)
and increase this value.
Solution 3:
You just need to take the current time in the QTimeEdit
and increase it by one second:
def time(self):
self.upTime.setTime(self.upTime.time().addSecs(1))
And make sure the QTimeEdit
is initialized properly whenever the up-time begins:
self.upTime.setTime(QtCore.QTime(0, 0, 0))
self.upTime.setDisplayFormat('hh:mm:ss')
Solution 4:
Here is a solution:
import sys
from PySide import QtCore
def calculo():
global time
time = time.addSecs(1)
print(time.toString("hh:mm:ss"))
app = QtCore.QCoreApplication(sys.argv)
timer0 = QtCore.QTimer()
time = QtCore.QTime(0, 0, 0)
timer0.setInterval(1000)
timer0.timeout.connect(calculo)
timer0.start()
sys.exit(app.exec_())
