For the time being, CannonField only contains an angle value for which we provide an interface using the same idiom as for value in LCDRange.

Finally, we emit the angleChanged() signal to tell the outside world that the angle has changed. The emit keyword is unique to TQt and not regular C++ syntax. In fact, it is a macro. -

 This is our first attempt to write a paint event handler. The event
-argument contains a description of the paint event. TQPaintEvent
+argument contains a description of the paint event. TQPaintEvent
 contains the region in the widget that must be updated. For the time
 being, we will be lazy and just paint everything.
 
 Our code displays the angle value in the widget at a fixed position.
 First we create a TQString with some text and the angle; then we create
-a TQPainter operating on this widget and use it to paint the string.
+a TQPainter operating on this widget and use it to paint the string.
 We'll come back to TQPainter later; it can do a great many things.
