我通过FTP接收二进制文件并将其存储为(Pdb) self.events[x]
<event.Event object at 0x7fce0b43c590>
(Pdb) type(self.events[x])
<class 'event.Event'>
(Pdb) self.events[x].time

(Pdb) type(self.events[x].time)

。原始图像是BMP，但要通过FTP我将其转换为QString。我能够成功接收这个二进制文件，但我无法转换回QPixmap或某种格式来显示该图像。
有没有人有任何建议？
答案 0 :(得分：1)
1）使用 QString :: toLatin1（），QString :: toLocal8Bit（）将QString转换为QByteArray数据。认为工作只是方法之一
2）用
读取QByteArraybool QPixmap::loadFromData(const QByteArray & data, ...
第一点的功能可能是将数据编码为另一种（文本）编码。然后尝试将QChar *从QString :: data转换为QByteArray。或者将QChar写入文件并从文件中读取QPixmap。
