Python 3.10 Pyqt5标签赢得了更改＆＃x27; setPixmap＆＃x27;需要时

Question

我目前正在运行python 3.10，并且在比赛/案例中并有一个奇怪的结果。让我解释一下：

我的代码图像

class Test(QtWidgets.QMainWindow):
def __init__(self):
    super(Test, self).__init__()

    # comboBox changes = image gets displayed on app 'WORKING'
    self.comboBoxIS.currentTextChanged.connect(partial(self.loadIsCombo, Testing=False))

    # Clicking 'Test' button to see if image is on the screen. At this point is on the app so technically it is.
    self.pushButtonIS_2.clicked.connect(partial(self.loadIsCombo, Testing=True))

def bufferIsCombo(self, Testing=False):
selectedItem = self.comboBoxIS.currentText()
bufferImg = 'resources/ui/buffering.png'
match selectedItem:
            case "Test 1":
                img = config['Test1']['Test1a']
                imgConf = config['Test1'].getfloat('Test1b')
                self.labelIS2.setText(str(imgConf))
                self.labelISConfig.setPixmap(QtGui.QPixmap(img))
                self.pushButtonIS_2.setEnabled(True) # Enable test button
                if Testing:
                    # Since the app contains the image i want to change it to another 'buffering'
                    self.labelISConfig.setPixmap(QtGui.QPixmap(bufferImg))
                    # This setPixmap wont get applied until handler returns but by that time is to late.
                    # imageSearchTest() come back as false positibe because it was on the application
                    functions.imageSearchTest()
            case "Test 2":
                pass
            case "Test 20":
                pass
          

一切正常运行，直到我遇到IF TESTING：strate for the if testing：statem 。新的self.labelisconfig.setpixmap（qtgui.qpixmap（bufferimg））在函数image> images eraperechtest之后才会更改。

问题是我在应用程序上显示该图像并运行图像搜索功能，因此它给了我误报，因为它在应用程序上找到了图像。为了解决此问题，我想将标签PixMap更改为DIF映像Bufferimg在功能开始运行之前，我不会得到那个假阳性。
