Question

我无法在GUI-PyQt4中上传图片。它无法在label_97中写入图像。请帮忙解决这个问题。

def uploadsignsCheck(self):
    fileName = QtGui.QFileDialog.getOpenFileName(self.label_97, 'Open File',"/usr/tmp","Images (*.png *.jpg *.jpeg *.bmp *.gif)")
    fname = image.open(fileName)
    data = fname.read()
    self.label_97.setpixmap(data)
    self.label_97.fname.write(data)
    fname.close()
    print(" pushButton_3 Clicked !")

您需要在setPixmap中输入图像的路径，无需将图像数据写入其中。

def uploadsignsCheck(self):
    fileName = QtGui.QFileDialog.getOpenFileName(self.label_97, 'Open File',"/usr/tmp","Images (*.png *.jpg *.jpeg *.bmp *.gif)")
    self.label_97.setPixmap(fileName)  # path goes here
    print(" pushButton_3 Clicked !")
