title: Radio button in Qt GUI
body: <p>I am using Qt5.2.1 and I made a program to do some stuff. In it I added a radio button (named 'others') i want that when the user clicks this button a line edit pops up besides it and lets the user enter some stuff inside it. when the user clicks another radio button, this line edit goes away. How do I do this?</p>
