TControl is the base class for FMX on-screen components. Subclasses are roughly divided into primitive shapes and styleable controls.

TControl extends TFmxObject to present objects that are seen, by adding properties and methods for:

• Size and position
  • Margins and padding
  • Alignment with others
• Visibility, opacity, scale, and rotation
• Mouse interaction and hit testing
• Keyboard interaction
  • Focus and tab order
• Triggers for animations and effects
• Painting
