Please use the properties ViewOptions, ViewOptionsEx, EditOptions and EditOptionsEx of the TWPRichText.
The TWPToolbar and TWPRuler both have a property DrawOptions.
Example:
WPToolbar1.DrawOptions := [ wptDrawPageShade ];
WPToolbar1.FlatButtons := true;
WPToolbar1.MarginBottom:= 8;
WPToolbar1.BevelLines := [ wplBottomShade ];
WPRuler1.DrawOptions := WPRuler1.DrawOptions + [wpDrawThemedBackground,wpDrawFramelines];
WPVertRuler1.DrawOptions := WPVertRuler1.DrawOptions + [wpDrawFramelines ];
WPRuler1.DrawOptions := [wpDrawPageShade];
WPVertRuler1.DrawOptions := [wpDrawPageShade];
WPRichText1.ViewOptionsEx := WPRichText1.ViewOptionsEx + [wpPaintPageShade];
WPPreview1.ViewOptionsEx := WPPreview1.ViewOptionsEx + [ wpPaintPageShade];
This will activate the new interactive Selection Mode
WPRichText1.ViewOptionsEx + [wppInteractiveSelectionMarker];
The markers can be moved by dragging the mouse or using a touch screen.
The properties FormatOptions and FormatOptionsEx change how the formatting routine works, they have a significant influence on how the text appears.
Please also see the Layout Catagory.
To change the language (for localization, translation) please see demo "Lozalisation".

Custom Theming:
If you don't like the default background of the TWPRichText you can use this event to draw your own:
event OnPaintDesktopBackground
If you just want to draw custom borders after the default code had been executed use
event AfterPaintDesktopBackground
Or, as mentioned above, use WPDrawRectWithBitmap_bitmap.
