HI
I have a function:

void MainWindow::WriteID()
{
...
}

I want to make a pointer to this function. here is my code:

void (*F_Code)() = MainWindow::WriteID;

but receive this error:

 error: void value not ignored as it ought to be
     void (*F_Code)() = MainWindow::WriteID;

why?

@rezaMSLM you need to google for "pointer to member function" to get the correct syntax.
Qt has to stay free or it will die.
