Use a QTimer and set its interval to 1000.
Then every second timeout signal gets fired and you can update(in the slot connected to timeout()) your timeline.

Yes you do.

So what you are saying is you don't understand how to get started writing a custom widget, right?

Qt has many, many examples of how to use standard widgets as well as how to write custom widgets. Why don't you start here: Widget Examples, especially examples such as Analog Clock that show how to use QPainter within a paint event to draw customized things inside a widget.

A hint: Start simple. Instead of trying to paint a beautiful time line widget like the screen shot you showed, do something simple - make a long rectangle with some numbers inside. Once you figure out how to draw and scale it properly, then you can add the other features to make it pretty.

I am also assuming that what you mean by the "time line" is only the part in the top-half of your screen shot. The menus, buttons, and other things in the toolbar below that can be done with standard Qt widgets inside of a layout.
