41 /** A theme is a set of properties describing fonts, colors, and bitmaps to be used to draw
42     background, pane borders, and view content.
43 
44     At the moment the properties can be accessed via the getPropertyValue() method.
45 
46     For a resource URL of a pane or a view you get the name of the
47     associated PaneStyle or ViewStyle.
48 
49     For the name of pane or view style suffixed with and underscore and the
50     name of configuration property, and maybe additionally suffixed by
51     another underscore and sub property name you get the associated
52     property.
53 
54     Example: you want to access the top left bitmap of a pane border
55         (simplified code):
56 
57     String sStyleName = getPropertyValue("private:resource/pane/Presenter/Pane1");
58     XBitmap xBitmap = getPropertyValue(sStyleName + "_TopLeftBitmap");
59 
60     For the offset of the bitmap you can call
61     Point aOffset = getPropertyValue(sStyleName + "_TopLeftOffset");
62 
63     This is work in progress.
