Painting

If skins are not defined:

The border around the editor has width defined in DisabledBorderWidth, EnabledBorderWidth, MouseInBorderWidth, FocusedBorderWidth properties. When auto-sizing the editor, it is assumed that the border width is equal to EnabledBorderWidth.

A border color depends on the editors state (normal, disabled, under the mouse pointer, focused) and SRVControlStyle: TSRVControlStyle property. If it is equal to srvcsSimple, colors are defined by RVControlsPainter (see the TRichView manual). If it is equal to srvcsClassic, colors are defined in EnabledBorderColor, DisabledBorderColor, MouseInBorderColor, FocusedBorderColor properties.

If SkinManager is assigned:

•the control is drawn using SkinManager.CurrentSkin.BoxSchemes[EditSkinSchemeIndex];

•the horizontal scroll bar is drawn using SkinManager.CurrentSkin.HorizontalScrollBarSchemes[HScrollBarSkinSchemeIndex];

•the vertical scroll bar is drawn using SkinManager.CurrentSkin.VerticalScrollBarSchemes[VScrollBarSkinSchemeIndex];

•font is defined in SkinManager.CurrentSkin.Fonts[SkinFontIndex].
