std::shared_ptr

Im new for Stackoverflow and QT Creator.

I want to ask that, I have std::shared_ptr<FILE> pipe(_popen(command.c_str(),"r"), _pclose); in my bool exec(std::string command){ function.

My question is, how can I display on textbrowser, std::shared_ptr<FILE> pipe(_popen(command.c_str(),"r"), _pclose);?

Normally ui->textBrowser->setText(); used for displaying textBrowser but it doesnt work in bool exec function. Thanks in advance.
