 ### Specifying MAVLink dialects
 The MAVLink dialect compiled by default by QGC is for the ardupilotmega. This will happen if no other dialects are specified. Setting the `MAVLINK_CONF` variable sets the dialects, with more than one specified in a space-separated list. Note that doing this may result in compilation errors as certain dialects may conflict with each other!
 
-### MAVLink dialect generator
-An add-on is available for QGC that provides a UI for generating MAVLink dialects from within QGC. This feature has been deprecated since identical functionality now exists within the MAVLink project itself. Enable this functionality by specifying the `DEFINES` variable `ENABLE_MAVGEN`.

 ### Opal-RT's RT-LAB simulator
 Integration with Opal-RT's RT-LAB simulator can be enabled on Windows by installing RT-LAB 7.2.4. This allows vehicles to be simulated in RT-LAB and communicate directly with QGC on the same computer as if the UAS was actually deployed. This support is enabled by default once the requisite RT-LAB software is installed. Disabling this can be done by adding `DISABLE_RTLAB` to the `DEFINES` variable.

-  or calculated by a QwtScaleEngine.
+  The scale of an QwtAbstractScale is determined by a QwtScaleDiv
+  definition, that contains the boundaries and the ticks of the scale.
+  The scale is painted using a QwtScaleDraw object.
+
+  The scale division might be assigned explicitly - but usually
+  it is calculated from the boundaries using a QwtScaleEngine. 
+
+  The scale engine also decides the type of transformation of the scale

-  \brief An abstract base class for slider widgets
-
-  QwtAbstractSlider is a base class for
-  slider widgets. It handles mouse events
-  and updates the slider's value accordingly. Derived classes
-  only have to implement the getValue() and
-  getScrollMode() members, and should react to a
-  valueChange(), which normally requires repainting.
+  \brief An abstract base class for slider widgets with a scale
+
+  A slider widget displays a value according to a scale.
+  The class is designed as a common super class for widgets like 
+  QwtKnob, QwtDial and QwtSlider.
+
+  When the slider is nor readOnly() its value can be modified 
+  by keyboard, mouse and wheel inputs. 
+
+  The range of the slider is divided into a number of steps from
+  which the value increments according to user inputs depend. 
+  Only for linear scales the number of steps correspond with
+  a fixed step size.
