FrameStyle

fsNone	no box at all
fsSimple	a single line box around the component
fsLowered	a box which appears to be lowered
fsRaised	a box which seem to be raised against its background
fsEngraved	an engraved line is drawn around the component
fsEmbossed	the box is formed by an embossed line around the component

Hint:

Please note that the frame forms the boundary of the component area (as defined by the properties Left, Top, Width and Height) and not that of the button glyph. If you want to draw a frame around the button image, you have to draw it within the button image, either by editing the resource file or by loading a user-defined glyph.
