我是PyQt5的新手,對Python很新穎。我試圖在Python 3.5中使用PyQt5創建一個圖形用戶界面,在這裏我點擊一個按鈕來啓動一個單獨的窗口,其中進度條迭代到100,然後在迭代結束時關閉窗口以生成一條消息「it工作」。Python 3.5,pyqt5進度條gui在單獨窗口中
問題是進度條被創建但不更新,到達結束後它不顯示它的工作消息。當我嘗試調試時,它完全崩潰,沒有警告爲什麼。我不知道該怎麼調試代碼
我的進度條代碼如下所示:
from PyQt5 import QtCore, QtWidgets
import sys
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName("Form")
Form.resize(1075, 84)
self.progressBar = QtWidgets.QProgressBar(Form)
self.progressBar.setGeometry(QtCore.QRect(30, 30, 1000, 35))
sizePolicy = QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Fixed, QtWidgets.QSizePolicy.Fixed)
sizePolicy.setHorizontalStretch(0)
sizePolicy.setVerticalStretch(0)
sizePolicy.setHeightForWidth(self.progressBar.sizePolicy().hasHeightForWidth())
self.progressBar.setSizePolicy(sizePolicy)
self.progressBar.setMinimumSize(QtCore.QSize(1000, 35))
self.progressBar.setMaximumSize(QtCore.QSize(1000, 35))
self.progressBar.setProperty("value", 0)
self.progressBar.setObjectName("progressBar")
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def setValue(self, val):
self.progressBar.setProperty("value", val)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Progress bar"))
主程序如下
from PyQt5.QtWidgets import QApplication, QDialog, QWidget, QPushButton, QMessageBox
import ProgressBar
import sys
class App(QWidget):
def __init__(self):
super().__init__()
self.title = 'PyQt5 button - pythonspot.com'
self.left = 200
self.top = 200
self.width = 320
self.height = 200
self.initUI()
def initUI(self):
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)
button = QPushButton('PyQt5 button', self)
button.setToolTip('This is an example button')
button.move(100, 70)
button.clicked.connect(self.on_click)
self.show()
def on_click(self):
print('PyQt5 button click')
app1 = QApplication(sys.argv)
window = QDialog()
ui = ProgressBar.Ui_Form()
ui.setupUi(window)
window.show()
for i in range(0, 100):
ui.setValue(((i + 1)/100) * 100)
app1.quit()
QMessageBox.information(self, "Message", "Data Loaded")
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())
給予任何幫助將不勝感激。
你能顯示代碼嗎? – Rahul
