TCustomSpeedButton.Spacing property
Spacing between the Glyph bitmap and the Caption for the control.
Declaration
property Spacing: Integer read FSpacing write SetSpacing default 4;Description
If Spacing is -1 and Margin is -1 then the glyph and the Caption are centered, with the same amount of unused space on each side of the control. If Spacing is -1 and Margin is not -1 then Spacing will fill the remaining unused space.
Changing the value for the property causes the preferred size to be recalculated, and the control is redrawn (in SetSpacing).
