Error description

• In a HATS RCP application you can override the getControlFont
  method in the RCPTemplate class to allow a custom font to be
  used for the controls on the screen.  However, when you change
  the font size in the getControlFont method the widgets in the
  RCP application do not get laid out correctly.  The font size
  does get changed for all the widgets but they are not realigned
  based on the new size and they will overlap in some cases when
  there are 2 widgets right next to each other.

  ****************************************************************
  The getControlFont method in the template of a HATS Rich
  Client project allows the font used for widgets to be changed
  dynamically in the project.  However, changing the font in
  this method was causing the rendered screen to be incorrectly
  laid out.  As a result, the end user could see fields
  overlapping or the text in the fields being truncated.
  

Problem conclusion

• The render methods of both the DefaultRendering and
  ComponentRendering classes were modified to apply the styles
  set in the template to the widgets before the layout method
  was run.  By doing this, the widgets would have the correct
  fonts already applied to them before the layout code, which
  determines the size and location of the widgets on the
  transformation, was run.
