How to read/write a text file in qt?

I have a QPlainTextEdit in my Form and I want to read the whole Resource.txt document which is placed in Other Files of my project and after a timer ticks i want the application save the contents of the QPlainTextEdit in the document. I know it's a dumb question but I can't find a solution.

The tutorial Getting Started Programming with Qt takes you through building a text editor, once you have followed this, try adding a QTimer to trigger a save.

QTextStream.readAll() lets you read a file to a QString. This constructor (or the method setPlainText) for QPlainTextEdit lets you set a string displayed in the editor. Use a QTimer to trigger a slot which reads the contents of the QPlainTextEdit into a QString with the toPlainText method after a desired amount of time. Write the result to file using a QTextStream again.
