PYQT並將文件讀取到Qtextedit

Question

我正在使用PyQt4，無法打開文本文件並將其顯示給Qtextedit。 “ print f +“這需要在textedit中進行”將其打印在此處，但公開表示沒有，任何幫助將不勝感激。

def convertDirectory(self):
    directoryPath = self.selectFilecsvtoxml()
    cmd = ('python loginformationExtractor.py '
           +str(directoryPath))
    print cmd + "   this is executable command"
    os.system(cmd)

    for file_name in os.listdir(directoryPath):
        print (directoryPath) + "****" + file_name

        if file_name.endswith(".txt"):
            f = file_name
            print f + "  this needs to go in textedit"

            readMe = open(f,'r').read()
            self.textEdit.setText(readMe)

我的錯誤/打印輸出：

/Users/eeamesX/work/data/releaseOct27****UUIDreadout.txt
UUIDreadout.txt  this needs to go in textedit
Traceback (most recent call last):
  File "/Users/eeamesX/PycharmProjects/Workmain/windows.py", line 2792, in convertDirectory
    readMe = open(f,'r').read()
IOError: [Errno 2] No such file or directory: 'UUIDreadout.txt'

def convertDirectory(self):
    directoryPath = self.selectFilecsvtoxml()
    cmd = ('python loginformationExtractor.py '
           +str(directoryPath))
    print cmd + "   this is executable command"
    os.system(cmd)

    for file_name in os.listdir(directoryPath):
        print (directoryPath) + "****" + file_name

        if file_name.endswith(".txt"):
            f = os.path.join(directoryPath, file_name)
            print f + "  this needs to go in textedit"

            readMe = open(f,'r').read()
            self.textEdit.setText(readMe

我認為您忘記添加目錄路徑文件。
