Bounds

The size and the position of the widget is condensed in the property bounds, but you have also the traditional properties like left an width.

// the types
sizety = record
  cx, cy: integer;
end;

pointty = record
  x,y: integer;
end;

rectty = record
case integer of
  0: (x, y, cx, cy: integer);
  1: (pos: pointty; size: sizety);
end;


// the properties
property Widgetrect: rectty read FWidgetrect write SetWidgetrect;

Enabled

property Enabled: boolean; default true;

Sets the widget enabled or not. Some Widgets change their look if they are not enabled, others do not.

Visible

Sets the widget visible or hides it.
