  35. //        Change History (most recent first, date in US form : mm/dd/yy):
  36. //
  37. //                        06/30/96    ca        Public release of version 1.2
  38. //                        06/28/96    ca        Added DisableSelf and EnableSelf methods
  39. //                        06/04/96    ca        made CW9 adjustments
  40. //                                                        Added guard macros in header files
  41. //                                                        Increased version to 1.2
  42. //                        05/25/96    ca        Relinquish memory used by the static PixMapHandle if no radio button is used anymore
  43. //                        05/23/96    ca        Updated the below changes (M™H) to allow the usage of either the standard radio button template
  44. //                                                            or the custom LAGARadioButton template. The standard radio button template is easier for layout
  45. //                                                            because you can see the text, but you cannot define directly a mixed value radio button
  46. //                                                        Defined class_ID1 and CreateAGARadioButtonStream1 to handle the two template possibilities
  47. //                                                        Added a CPPb to "LAGARadioButton CPPb.rsrc" called LAGARadioButton1 to handle the standard
  48. //                                                            radio button template, without having to tinker the class ID
  49. //                                                        Added a static RegisterClass method to simplify the class registration
  50. //                        05/23/96    M™H        Changed the stream constructor to use the standard radio button template in Contructor
  51. //                                                            which enables to see the text put in a radio button while defining the view
  52. //                        05/16/96    ca        Increased version to 1.1
  53. //                                                        Added copy constructor
  54. //                                                        Added "on the fly" constructor
  55. //                                                        Added GetDescriptor and SetDescriptor
  56. //                                                        Added SetTextTraitsID and GetTextTraitsID
  57. //                                                        Added change history
  58. //                        05/15/96    M™H        changes proposed by Michael(tm) Hamel <mhamel@adi.co.nz>    (Thanks a lot ;)
  59. //                                                        use a static PixMapHandle for FASTER draw of the button (uses less code too)
  60. //                                                        Note : the previous drawing method is available conditionnaly by defining SLOW_AGA_RADIO_DRAW
  61. //                                                                        which uses more code, but less data (we never know who could need this ;)
  62. //                                                                        To compare speed, with M™H's method, drawing 135 radio buttons on a 9500/120
  63. //                                                                        takes around 0s20 and with the SLOW_AGA_RADIO_DRAW method, the same takes around 1s70
  64. //                        04/22/96    ca        class made available by Christophe ANDRES <chrisoft@calva.net>
