Qt-使用用户文本输入直接定向到文件夹

Question

Is there a way to include user text input in a file address? For example:

The user inputs a first and last name, and it is saved as Qstrings firstname and lastname . I want to then access a folder that is named firstname_lastname (Ex: John_Doe`), saved in location like this one:

C://Users/User/Documents/Patients/firstname_lastname

How would I go about using those strings to direct to that folder?

Answer 1

Use arg()

qDebug() << QString("C:/Users/User/Documents/Patients/%1_%2")
.arg(ui->lineEdit->text())    //firstname
.arg(ui->lineEdit_2->text()); //lastname

I don't know what exatly you want, but you can use this to open directory. Or you can use QDir
