+/** A theme is a set of properties describing fonts, colors, and bitmaps to be used to draw
+ background, pane borders, and view content.
+
+ At the moment the properties can be accessed via the getPropertyValue() method.
+
+ For a resource URL of a pane or a view you get the name of the
+ associated PaneStyle or ViewStyle.
+
+ For the name of pane or view style suffixed with and underscore and the
+ name of configuration property, and maybe additionally suffixed by
+ another underscore and sub property name you get the associated
+ property.
+
+ Example: you want to access the top left bitmap of a pane border
+ (simplified code):
+
+ OUString sStyleName = getPropertyValue("private:resource/pane/Presenter/Pane1");
+ XBitmap xBitmap = getPropertyValue(sStyleName + "_TopLeftBitmap");
+
+ For the offset of the bitmap you can call
+ Point aOffset = getPropertyValue(sStyleName + "_TopLeftOffset");
+
+ This is work in progress.
