void MainWindow::print()
{
input_events * ptr_ie;
ie * ine;

QString resultString = "";
for(ine=ptr_ie->l; ine; ine = ine->suiv)
{
ui->textBrowser->setText(ui->textBrowser->toPlainText() + resultString.setNum(ine->id) + " ");
}
}


The problem is that does not print output in function print() "Print all"


Thank you for your time

your code and variable usage is very difficult to understand, I think you have to write a clear code for people to pay attention your problem. Whatever, it seems that ptr_ie is a kind of container that holds structs in your code and you are creating new ptr_ie pointer to object each time your Get_ınfo function is called and also in print function your newly created ptr_ie is decalred without any initialization so of course you will reference unrelated part of your memory. Declare your input_events * ptr_ie as a private member in your Mainwindow class and define it in your constructor and remove ptr_ie declarations from your get_info and print function.
Don´t let your fears stand in the way of your dreams!
