  Revision 1.4  2002/04/13 00:32:16  memson

  Added MMemo_Text and MMemo_TextLength. Updated the testfile demo to save
  text from a MMemo when button clicked.

  Revision 1.3  2002/04/12 23:32:56  memson

  Added quite a bit.

  Got basic file handling soeted out. Also got the FilePanel's working (see
  example project)

  Popup menu now only responds to a right click (at last!!)

  Revision 1.2  2002/04/02 20:42:15  memson

  updated for Eric

  Revision 1.1.1.1  2002/03/31 10:36:07  memson

  initial import into sourceforge

  Revision 1.20  2002/03/28 08:41:02  memson

  Commited to main tree by the above on behalf of :

  2002/03/26 21:47:13 Jourde
  Adding MApplication_AddForm_int32 to create form with correct position (for
  Pascal)

  Revision 1.19  2002/03/26 13:28:51  memson

  added in combobox support - flawed at the moment.

  Revision 1.18  2002/03/14 22:31:41  memson

  Got the Menubar/menu/menuitem and popupmenu/menuitem both working... Had a
  bit of a slack night, so didn't really do much else.

  Revision 1.17  2002/03/14 00:12:38  memson

  Revised the event and property class hierarchies... hopefully makes more
  sense.

  Started to add in the Menu functionality. PopUpMenu is done and 'tested',
  but the BMenuBar/BMenu (mainmenu) stuff is there but untested.

  Added in an OnCreate and OnDestroy event to the events, plust a wierd
  offshoot class to handle the menuitem click.

  Revision 1.16  2002/03/12 23:12:37  memson

  hashed out some details - stopped child windows from screwing up app, and
  also added the close action to form and terminating functionality to the app.

  Revision 1.15  2002/03/12 18:39:16  memson

  Revision 1.14  2002/03/11 23:54:06  memson

  the form works more happily, also sorted out form canvas issues.

  lost hours of work pissing about with pascal - needs quite a bit of revision
  to get it happily working with fpc.

  Revision 1.13  2002/03/11 23:22:11  memson

  Revision 1.12  2002/03/03 11:31:38  memson

  began adding a class to hold additional properties (Owner and Tag for now).

  Revision 1.11  2002/02/19 17:49:53  memson

  Added half arsed support for multiple windows - not working quite right yet,
  but at least they seem to 'work' in so much as they don't wipe the app out.
  The secondary forms Canvas is screwed up a little.. that is a priority I
  guess.


  Revision 1.10  2002/02/18 19:28:34  memson
  No *major* changes, cleaned things up a lot. Created MEventPlugin and now
  use multiple inheritence to implement most of the event pointer storage.
  This makes things a lot neater and also ensures that I don't have to write
  the same code loads of time (mostly).

  Revision 1.9  2002/02/14 23:39:53  memson
  I've now added most of the events to the MButton, MCanvas, MMemo and MEdit..
  started a MPanel component. Again, the MCanvas is *not* tread safe!!!
  This means the calling thread must create it.

  NB. Before I add much more functionality, I'm going to look at other GUI
  libs to see if there are any controls worth borrowing.

  Next control will probably be a MLabel followed by a MMenuBar and MMenuItem.
  MForm will own a MMenuBar.

  Revision 1.8  2002/02/14 20:33:19  memson
  Got the MButton OnClick, OnMouseDown/Up, OnKeyDown/Up and OnMouseMoved
  events working. Started to add the required code to the rest of the classes
  (should be a cut/paste job).

  Revision 1.7  2002/02/14 14:00:16  memson
  fiddled a bit.. nothing major.

  Revision 1.6  2002/02/13 23:26:25  memson
  Got the MMemo working.
  Got the MEdit working, including OnClick event signal
  Got the MButton working with a signal
  Added a few get/set accessor routined for captions/text.

  Revision 1.5  2002/02/13 00:02:02  memson
  Got the MTextControl basic functionality - annoying fact is that a text
  control has to be added inside the thread that will display it!!!!

  Revision 1.4  2002/02/12 19:40:59  memson
  Removed the Sender param for the MButton::DoClick()

  Revision 1.3  2002/02/11 23:26:44  memson
  Revision 1.2  2002/01/17 20:32:54  memson
