我想你可能是錯的。你希望你在一個單獨的線程中做的工作，所以它不會凍結應用程序。但是你也希望能夠更新進度條。您可以通過使用QThread創建工人類來實現此目的。 QThreads能夠發出信號，您的用戶界面可以聽取並採取適當的行動。
首先，我們來創建你的工人類。
#Inherit from QThread
class Worker(QtCore.QThread):
#This is the signal that will be emitted during the processing.
#By including int as an argument, it lets the signal know to expect
#an integer argument when emitting.
updateProgress = QtCore.Signal(int)
#You can do any extra things in this init you need, but for this example
#nothing else needs to be done expect call the super's init
def __init__(self):
QtCore.QThread.__init__(self)
#A QThread is run by calling it's start() function, which calls this run()
#function in it's own "thread".
def run(self):
#Notice this is the same thing you were doing in your progress() function
for i in range(1, 101):
#Emit the signal so it can be received on the UI side.
self.updateProgress.emit(i)
time.sleep(0.1)
所以，現在你有一個工人班，是時候利用它了。您需要在Ui_Dialog類中創建一個新功能來處理髮射的信號。
def setProgress(self, progress):
self.progressBar.setValue(progress)
雖然你在那裏，你可以刪除你的progress()函數。
在retranslateUi()你會想從
self.pushButton.clicked.connect(self.progress)
更新按鈕事件處理程序
self.pushButton.clicked.connect(self.worker.start)
最後，在setupUI()功能，您將需要創建你的工人類的一個實例並將它的信號連接到你的setProgress()功能。
在此之前：
self.retranslateUi(Dialog)
補充一點：
self.worker = Worker()
self.worker.updateProgress.connect(self.setProgress)
下面是最終代碼：
from PySide import QtCore, QtGui
import time
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(400, 133)
self.progressBar = QtGui.QProgressBar(Dialog)
self.progressBar.setGeometry(QtCore.QRect(20, 10, 361, 23))
self.progressBar.setProperty("value", 24)
self.progressBar.setObjectName("progressBar")
self.pushButton = QtGui.QPushButton(Dialog)
self.pushButton.setGeometry(QtCore.QRect(20, 40, 361, 61))
self.pushButton.setObjectName("pushButton")
self.worker = Worker()
self.worker.updateProgress.connect(self.setProgress)
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
self.progressBar.minimum = 1
self.progressBar.maximum = 100
def retranslateUi(self, Dialog):
Dialog.setWindowTitle(QtGui.QApplication.translate("Dialog", "Dialog", None, QtGui.QApplication.UnicodeUTF8))
self.pushButton.setText(QtGui.QApplication.translate("Dialog", "PushButton", None, QtGui.QApplication.UnicodeUTF8))
self.progressBar.setValue(0)
self.pushButton.clicked.connect(self.worker.start)
def setProgress(self, progress):
self.progressBar.setValue(progress)
#Inherit from QThread
class Worker(QtCore.QThread):
#This is the signal that will be emitted during the processing.
#By including int as an argument, it lets the signal know to expect
#an integer argument when emitting.
updateProgress = QtCore.Signal(int)
#You can do any extra things in this init you need, but for this example
#nothing else needs to be done expect call the super's init
def __init__(self):
QtCore.QThread.__init__(self)
#A QThread is run by calling it's start() function, which calls this run()
#function in it's own "thread".
def run(self):
#Notice this is the same thing you were doing in your progress() function
for i in range(1, 101):
#Emit the signal so it can be received on the UI side.
self.updateProgress.emit(i)
time.sleep(0.1)
if __name__ == "__main__":
import sys
app = QtGui.QApplication(sys.argv)
Dialog = QtGui.QDialog()
ui = Ui_Dialog()
ui.setupUi(Dialog)
Dialog.show()
sys.exit(app.exec_())
QThreads有一些內置自動發射的信號。你可以看到它們，關於QThreads的更多信息in the documentation
是的，這就是我想要的樣子，謝謝！ – Benny
