Question

我是PyQt4的新手，正在学习如何在后端将它与我的Python代码集成。我做的方式，前端看起来很好，并采取我需要的所有输入。处理开始时，即后端脚本运行时，窗口消失，并在我的所有后端脚本完成后重新出现。该窗口应该显示正在进行的进程的状态（在后端）。请帮帮我。

Win2上的一个按钮使其切换到Win4，即Win4消失后，所有后端处理完成后重新出现。

代码段：

class Win2(QtGui.QMainWindow, w2):

def __init__(self, parent=None):
    QtGui.QMainWindow.__init__(self, parent)
    self.setupUi(self)
    self.move(500,200)
    self.window1 = None
    self.window4 = None
    self.window5 = None
    self.window6 = None
    self.pushButton_2.clicked.connect(self.showWin4)
    self.pushButton_9.clicked.connect(self.showWin5)
    self.pushButton_5.clicked.connect(self.showWin6)
    self.pushButton_8.clicked.connect(self.openIP)
    self.pushButton_7.clicked.connect(self.opencred)
    self.pushButton_6.clicked.connect(self.showWin1)

def openIP(self):
    self.filename = QtGui.QFileDialog.getOpenFileName(self, 'Open File', '.')
    #print filename
    self.label_7.setText(self.filename)


def from_alldevicesrun(self):
    #print check_port.all_ips
    with open(self.filename, "rb") as csvfile:
        iprow = csv.reader(csvfile, delimiter='\n')
        for [ip] in iprow:
            #print ip
            from_alldevices.ips.append(ip)

    csvfile.close()

    from_alldevices.main()


def opencred(self):

    self.filename1 = QtGui.QFileDialog.getOpenFileName(self, 'Open File', '.')
    #print filename1

    self.label_9.setText(self.filename1)

def see_cred(self):
    '''
    import __builtin__
    __builtin__.x = self.filename1
    import check_credentials_both
    '''
    cmd = ['python', 'c.py' ]
    cmd_out = subprocess.Popen( cmd , stdout=subprocess.PIPE).communicate()[0]

    self.close()        
    if self.window4 is None:
        self.window4 = Win4()

    form = Win2()
    form.show()
    sys.exit(app.exec_())

提前谢谢。

您想使用hide()而不是close()。当您呼叫self.close()时，您正在进行QMainWindow停止并可能设置为删除。使用hide()只会让窗口隐藏，直到您再次show()为止。

def showWin4(self):
    self.hide() #This should be a hide not close
    if self.window4 is None:
        self.window4 = Win4()       
    self.window4.show()

后端运行时PyQt4窗口消失，完成后重新出现
