TDividerBevel is a component that creates a caption with beveled line on a form. A TDividerBevel is a descendant of TGraphicControl and is available under the LazControls tab of the Component Palette.
TDividerBevel can be horizontal or vertical, bevel can be lowered or raised, with several graphic styles (property Style).
Property BevelWidth is by default set to -1 because of backward compatibility. Negative values mean that bevel width is Max(3, TextHeight div 5). Positive values mean simply pixels.
Property LeftIndent is by default set to 60, again, for backward compatibility. Negative values mean that caption is centered. Positive values are pixels. Position of caption respects bi-directional mode.
