15.12. posting package to comp.sources.misc
  saved in grafix/post-15.12

added scrolling with keys : PgUp/Dn arrow-up/down to file selection box
  -> files.c

16.12 : cleanup event mask setting; default selection_mask for the window
class is only Expose and Configure, derived classes add masks by demand ->
less events, more transparency
-> window.c

17.12 - 19.12:

calc.c - name conflict for Solaris (div-> divi) resolved
files.c - extended for complete viewing of texts
         new classes :vert_scrollbar, text_window, text_viewer 
(files-demo.c) - deleted , replaced by :
file-browser.c - demo for file viewer with spawning and loading new files, 
	also with file_selection_box
files.c - file_selection box extended :
	now has scrollbars for directory and file selector with standard 
	3-button interface (button 1/3 = pgup/dn, button 2 = draw/set)
	also key-events : next,prior, arrow-keys
	button-1-press (in selector) -> select file/directory

window.h - constructor delete_button for menu_bar parent def.
lat_win.c - added z-axes ticks

23.1:
window.c - bug with WatchCursor fixed : it didn't vanish when other main
	windows were spawned. (there was only one global pointer "watch_main")
	New solution : no more restore in event loop, but explicitely
	to call ResetCursor(); after computation
	corrections : window.h, lat_man.c, one-dim, two-dim
lattice: floating point prints (ticks, gamma) %f -> %g for better
	readability

20.2.
grafix.mk : HOSTTYPE (nonportable) replaced by uname (portable)
lat_win.c : z-ticks also for small heights (ntick > 0)


27.2
Makefile : make depend introduced (File .depend) by help of Ulrich Lauther

Weird behaviour on "Close" via window manager resolved. If it was done 
for a child then the whole program crashed with :
   XIO:  fatal IO error 32 (Broken pipe) on X server ":0.0"
      after 626 requests (622 known processed) with 0 events remaining.
      The connection was probably broken by a server shutdown or KillClient

   explanation (see mwm.1)

     f.kill
          This function is used to terminate a  client.   If  the
          WM_DELETE_WINDOW protocol is set up, the client is sent
          a client message event, indicating that the client win-
          dow  should be deleted.  If the WM_SAVE_YOURSELF proto-
          col is set up and the WM_DELETE_WINDOW protocol is  not
          set  up,  the  client  is  sent a client message event,
          indicating that the client needs to prepare to be  ter-
          minated.    If   the   client   does   not   have   the
          WM_DELETE_WINDOW or WM_SAVE_YOURSELF protocol  set  up,
          this function causes a client's X connection to be ter-
          minated  (usually  resulting  in  termination  of   the
          client).   Refer  to the description of the quitTimeout
          resource and the WM_PROTOCOLS property.
solution: 
  XSetWMProtocols WM_DELETE_WINDOW for all main_windows;
  a global top_main is declared (which is always the first created main_window)
  and a event_handler main_window::ClientMsg_CB defined to handle these ev

9.6.
scrollbars (even pure_scrollbars) get a member nticks, (which is 0 by default)
and determines the number of tick lines to display on x-the axis
changes in window.h, window.c

21.6.
clock_win : in window.c/h added. A class to display a simple analogue clock
also a demo clock_demo.c written.

23.6.
main_window - constructor allows argument fix_pos = 2 : map at center of the screen

30.6.
palette.c : handler for error "no more color cells" changed; now only warning
 	so more than 2 lattice applications can run at the same time on one 
	display

12.7
animator and replay included in grafix (from dymos) 
	replay as a demo, video files are in subdirectory video

19.7
window.c,h: bug fixed : close button of window manager used to kill the appl.
	main_window class : XSetWMProtocols added, and
	event handler for ClientMessage to unmap or exit. 
	To find the top main_window the variable top_main is used. 
	For this the close button invokes exit, else only unmap
	(Does not work properly if an marginal window created as first mw) 

26.7. lattice.* : z0 - as shift value introduced, also as managed value
	
4.8.
three-dim.c (and wave.c as ex.) the prototype for any interactive integration 
	program, simplified interface : integrator class (s.below)
animator.*, replay.c : extended with new classes : 
	time_lat, play_lat, play_main, player, integrator

8.8.
lattice.* : the value display window (display_cursor) is now defined as
	a main window -> no more clipping. It now follows the pointer directly
	-> search the nearest lattice point in 3-dim !
	
lat_win.c : function "make_lattice" replaced by generalization of "make_body"
	now the value display works for all types of displays, since scp
	is always correct !

28.8.
polling mode changed : now polling_handler is a virtual function in main_window
	and polling_mode is member -> changes in window.*, clock-demo, animator.*
	simplified !

1.9. 
replay.c : synchronization from child to parent fixed (with signals)
	Now the child process can also be ended, and a new video file can
	be loaded.

28.9.
switch_button : introduced in window.h/c

2.10.
scrollbar : error fixed with move & callback mechanism, since the callback was 
	invoked with actual slider pos (in pixels) this lead to rounding errors
	now : extra methods "move" and "move_cb" are defined. On mouse positioning
	move_cb is invoked, otherwise from "change" -> move and callbck_val 

tick_scrollbar & play_scrollbar included in window.c/h

20.10
new classes in window.c/h:
==========================
scrolled_window : a window with virtual size that can be moved with
	scrollbars if it is larger than the actual window. Proper resizing !

twodim_input : a twodimensional "scrollbar" to get user input from mouse
	derived from that : 
horizontal_shifter, vertical_shifter : are needed by scrolled_window

demo for these : scrolled_demo, class_browser 

26.10. 
files : text_viewer fixed, tabs, scrolling
tree graphics
=============
class_browser: nearly completed, failures if graph contains unbalancable 
"cycles"
	eg        class1
	         /    |
	        c2    |    
	         \    |
	          class3
	and insertion sometimes failes ( /fgrab/ )
27.10.
tree.c/tree.h separated 
dir-tree.c : new simple demo for the use of tree classes, should
	serve as learning model

29.10.
one-dim/two-dim : new "run" button included to match newer apps.

30.10.
gccinc : subdirectory for gcc-lib include files that are needed for 
	regexp parsing (class-browser), 
	which are not on all systems installed (Sun)
	will be included in the tar file
window.c/h : irint and sincos for Suns replaced by simple standards
	because older SunOS seem to don't have them 

31.10.
calc.c : keyboard input of numbers and arith. operators -> new

german clean : win-demo.c, edit-demo.c, one-dim.c, two-dim.c, window.h (sigh !)
  	window.c (sigh !)

edit_window : cursor works now correct in all color modes (8bpp, 16bpp)

1.11.
window.c : destructors cleaned up, now also the entry in parents child list is
	correctly removed -> also static windows can be defined and deleted !!
	Whow !!
	
palette.c : TrueColor mode now supported for >= 16bpp !! 
	minor drawback: if the palette changes, it is not visible for
	lattice windows immediately, but only when next draw occurs


3.11.
german clean : lattice.h lat_win.c lat_man.c reg_man.c (also help page)
	-> it should be complete now !!

replay : help text (help button) included

class-browser : error fixed (undefined classes -> path == 0)

4.11.
popup buttons : new feature : on second press unmap the popup 
	(also help_button -> now a subclass of popup_button) 

error in three-dim fixed : difficult to find : in animator.c was a erroneous
	allocation with "char(200)" (wrong brackets) which resulted in 
	subsequent failures of simple "new char[8]" (but correct ones!)

======================================================================

4.11.95 19:07 version 1.2 uploaded to sunsite, LSM entry mailed, announce posted

====================================================================
6.11.
animator : class replayer gets a rotate button and so "three-dim" and "replay"
	have this option, help text added
	polling_handler -> step_handler

window.h:  irint macro does not use rint anymore -> HP error

7.11.
window.c : hash table for mapping X-IDs to window pointers implemented
	-> now there is no more limit of the number of windows and they
	may be constructed and deleted in any fashion !!!

11.11.
dir-tree.c : now links are not further parsed (it gave horrible trees)
	(problem was to use lstat instead of stat)
	action on BPress : display directory contents in a popup window

=======================================================================

... ????

24.11.96 

lattice: isoline mode implemented

window.h/c : basic colors Red,Green,Blue,Yellow,Violet defined

26.11.

window.h/c : scrollbar variables changed from int -> float
	     better fit for numerical applications

8.12.
window.ch : virtual resize method for coord_window implemented,
	    now scaling factors are automatically adapted
 
15.12.
window.ch : radio_buttons are derived from toggle_buttons, they have now
	    attached an marker that shows which value is active.
	    Initialization is not quite good yet (default -1 : no value)
	    If a value is given, it should be inizialized automatically

17.12.
animator : buttons >> and || unified to one switch_button (for similarity)

24.12.-27.12
tree.c : error cleaned with virtual height (showed in class-browser, dir-tree)
	 yc in rec_geometry was not initialized !
	 * "lin_tree" is build in Tree constructor -> hide from application
	   declared in tree.h, dir-tree is simpler now
         constructor for Tree : if parent given : update its child-list

28.12 
files.ch : * cofirm_box no more static -> caused errors sometimes
           * new interface function :
             int yes_no_box(char *title, char **text, int w=200, int h = 120);
	   * in 'open_file_interactive' static definitions changed to stack
	     eg : 'static file_selection_box fsb';
	     caused errors in desctructors ???!!

31.12.
tree.ch :  color_button : virtual void bpress(XButtonEvent*) { }
	   to catch all mouse buttons in Node::Press_cb(XButtonEvent*)

4.1.97:
window.c : * error(char *fmt, ...) now takes args like printf -> simpler to use
           * PlaceText : XSetFont(...fixed_fn) is reset after Drawing
 
	 
10.1. 
files.h, lattice.h : #ifndef .... #endif wraps  
window.ch : "printw" like printf in windows implemented with variable args

15.1.
files.ch : class definitions moved from c->h to enable other applications
font-selector.ch : defines a window for interactive selection of Xfonts
font-browser: new demo : browse through all Xfonts !

25.1
mandel.c : new demo for Mandelbrot set

14.3.
bug-fix: sometimes wrong font used at start (not fixed)
  in init_globals added :
  XSetFont(display, gc_copy, fixed_fn->fid); // default font 

17.3.
Email from sunsite : 
At about Mar 16, 1997 16:28:51 EST, I made `keeper' move the following files
from X11/devel to X11/devel/c++libs:

grafix.1.2.README        (no description)
grafix.1.2.tgz           C++ library for writing X programs
grafix.1.2.tgz.lsm       (no description)

Thank you for your contribution of time, effort, and creativity.

28.4.
earth.c : great new demo for rotating earth, very nice !! 
mapdata.c - data for earth (adopted from the xearth demo)
	the remarkable for this demo is its animation speed, since the 
	projection is always computed, not stored as video !

6.6.
palette.c: minor bug fixed: 
	if not enough color cells it did not set scrollbars (return -> break)

16.6. 
window.ch : minor bugfix: "set_color" takes unsigned long as arg

21.6.
palette.ch : constructor for palette_popup has optional argument palstr*
	for initialization 

7.7.
Makefile : tgz file is now expanded to grafix1.4 subdirectory
tree.c : gcc warnings eliminated

=============================================================================

uploading to sunsite:

file HOW.TO.SUBMIT:
NOTE: DON'T UPLOAD TO /pub/Linux/Incoming ANYMORE! IT WILL NO LONGER WORK!
And uploading pirated commercial software won't help anybody.  We delete it.

To submit Linux stuff to sunsite, do this:

   1) Get LSM-TEMPLATE from /pub/Linux/Incoming
   2) Fill out the lsm entry as described
   3) Upload your files and a .lsm file containing an lsm entry
      to  /incoming/Linux (note: uploading to pub/Linux/Incoming
      is no longer permitted).

Step 3 is no longer optional. The archive has gotten too large to
maintain by hand, and our helper tools depend on LSM information.
Anything you submit without an LSM will be rejected; you'll get an
email form letter about it if we can figure out who you are without
too much effort.

When you name your upload files, please pay attention to the guidelines
for naming things in the file NAMES.  Also, please try to use one of the
standard Copying-Policy fields from LICENSES.  Doing these things will
make the maintainers' lives easier (remember, they're all overworked
volunteers!).  This will get your software processed faster.  It will make
you wiser, stronger, sexier, brighten your teeth, and improve your karma.
And it's the right thing to do!

Subject: sunsite action notice from the `keeper' program

At about Jul 11, 1997 11:30:12 EST, `keeper' moved the following files from
Incoming to libs/X/c++libs (C++ class libraries for X development):

grafix-1.4.README        
grafix-1.4.lsm           
grafix-1.4.tar.gz        C++ library for writing X programs

These replaced the following files:

grafix.1.2.README        
grafix.1.2.tgz           C++ library for writing X programs
grafix.1.2.tgz.lsm       
------------------------------------------------------------------------------

14.7. 97:
posted README file to "comp.graphics.visualization"

15.7. 
Email to: linux-announce@news.ornl.gov -> post to "comp.os.linux.announce"

12.1.98
bug-fix for *pulldown-menus*: now inside separate function 'handler' 
  failure to grab the pointer properly -> fixed (eg. in combination with lattice window
  the pointer was sometimes interpreted to rotate the lattice display)
  XGrabPointer no more used !
  This should also fix the hangups in debugging with gdb (due to grabbed X-pointer)
  Now pulldown_menu has a vector of buttons, and only these windows are
  processed when the pulldown_button in pressed !
  Also two global variables are removed

26.1.98
tree.c : Minor geometry-improvement
   better horizontal orientation : compute max width for each depth
   and position xp to this, application may use bwmax to set max witdh
  
10.7.98
files.c : limit of max 200 files per directory changed to 1000

3.9.98
window.* : DrawString && printw return string length

6.1.99
window.* : Help Popups generally redesigned: methods "add_help" allow dynamical
	helps, which will popup on entering the window , problems with delayed popup
	(asynchronuous X-calls) -> see 15.4.99

17.3.99
all : ** fitting for egc-compiler **
    problems with typecasts of class member functions -> warnings 
    use of #pragma interface/implementation -> linker warnings

26.3.99
main_window class : default constructor now places the window in the center of
   the screen (fix_pos = 2)
   problems with new window-managers (kde) and window placing fixed

15.4.99 (see 6.1.99)
window.* : new help-functionality added, window-function add_help(...) generates
  popup-menus, which show (after 1sec delay) when the pointer enters the window
  closing is done in event_loop, problems with signal-handling solved (?)

16.4.99
window.* : buttons may be disabled, two functions to toggle state
  void disable(), void enable() 

20.6.99
grafix.mk, tree.* : some small changes

29.6.99
class-browser.c : bug-fix in 'parse_file' which caused segfaults sometimes :
		char *buf = new char[bufsize+1]; // the buffer for ClassBuffer

5.9.99
window.* (+ tree.*) : buttons (plates) may now have different colors than the 
	 default light-blue. Use the method "set_GC(&gc3)" to set all three GCs
	 needed for 3d-shapes. gc3 may be constructed by the function
	 "void color_GC(unsigned short r, unsigned short g, unsigned short b, GC3 *gc3);
15.9.99
window.* : added function 'map_state()' to window-class  for simple testing, 
	 if window is viewable via 'XGetWindowAttributes' (quite slow!)

18.9.99
window.* : for faster querying of mapping state : window-variable 'Bool is_mapped'
	 which is set by 'Map()' and 'Unmap'. Do not use other functions to map/unmap 
	 a window, else it is inconsistent ! 

4.4.00
window.* : adapted for gcc-2.95.2, (errors when compiling with new gcc fixed)
	 esp. pointers of member functions like in 'stp->switch_play_mode(&play_scrollbar::step_fwd, this);'
mandel-new.C : nice new features, for parallelizing 

9.5.00 
window.h, jpeg.c: JPEG file output for all windows, pixmaps use Pixmap instead of Window
 (only works for 16-bpp displays !!!)

window.* :
21.12.00 : Copyright changed to general LGPL
