Novice, a first-time Qt, you require the MFC framework of the read file under the function of transplanted to Qt, after transplantation code as follows, but clearly it needs TXT file, it is bounced said cannot find the file, please comment what reason be?

CodePudding user response:

QFileDialog: : the third parameter is the folder path of getOpenFileName method, should be a hint to find: E: \ \ gpt2_1wA_World TXT this folder

CodePudding user response:

Are you sure this TXT in the path, you wrote the "E: \ \ gpt2_1wA_World TXT" to "E:/gpt2_1wA_World. TXT" have a look at,

CodePudding user response:

You just to read the file content:

That's fine directly

QFile file (" E: \ \ gpt2_1wA_World TXT ");
if (! File. The open (QIODevice: : ReadOnly)) {
//failed to open the file
return;
}
