32 /** A theme is a set of properties describing fonts, colors, and bitmaps to be used to draw
33     background, pane borders, and view content.
34 
35     At the moment the properties can be accessed via the getPropertyValue() method.
36 
37     For a resource URL of a pane or a view you get the name of the
38     associated PaneStyle or ViewStyle.
39 
40     For the name of pane or view style suffixed with and underscore and the
41     name of configuration property, and maybe additionally suffixed by
42     another underscore and sub property name you get the associated
43     property.
44 
45     Example: you want to access the top left bitmap of a pane border
46         (simplified code):
47 
48     OUString sStyleName = getPropertyValue("private:resource/pane/Presenter/Pane1");
49     XBitmap xBitmap = getPropertyValue(sStyleName + "_TopLeftBitmap");
50 
51     For the offset of the bitmap you can call
52     Point aOffset = getPropertyValue(sStyleName + "_TopLeftOffset");
53 
54     This is work in progress.
