RAD Studio
Speed Buttons

Speed buttons (TSpeedButton), which usually have images on their faces, can function in groups. They are commonly used with panels to create toolbars.

  • To make speed buttons act as a group, give the GroupIndex property of all the buttons the same nonzero value.
  • By default, speed buttons appear in an up (unselected) state. To initially display a speed button as selected, set the Down property to True.
  • If AllowAllUp is True, all of the speed buttons in a group can be unselected. Set AllowAllUp to False if you want a group of buttons to act like a radio group.
