Detailed History
----------------

0.00	July 1992

Stored the whole HD directory tree as a file and loaded it each time it was
run. To update the tree, had to delete the file and run again. A bit crap,
but I used it every day for months, and it saved a lot of time!


1.00	May 1993 

Having seen !QuickDir by Clive Jones, I decided to provide menu-making on the
fly as well, so the menu tree was always up-to-date. Also converted to
DeskLib, which is superb. Added the configuable root menu featue.


1.10	May 5 1993 

Now displays icons in the menus. Discovered that the Wimp sends a message
with action code 0x400c9 when a menu is removed without a selection being
made (e.g. a click off the menu). This is used to release all claims on
further messages, which are detected when the menu is open in order to create
new sub-menus when MENU_WARNING messages are sent by the WIMP.


1.20	May 12 1993 ** First release ** 

Added the Info/Quit menu. The Info box is my first ever dialogue box, and I
don't know how to make it moveable like all other dialogue boxes I've seen.


1.21	May 24 1993 

Added the options to open the root menu on the left hand side of the screen,
as suggested by Kai Schlichting. Fixed a minor bug which resulted in a
garbled title bar of the submenu of a '@' root item. I've now read the
comp.sys.acorn Application Writer's Guide, so there is now no !Boot file, and
I've found out how to make the Info window movable (process event_OPEN
events).


1.30	** Second release ** 

Added Help to normal menu. Added 'Edit Configs' and 'Update' to normal menu.
These do a poor-man's implementation of a proper dialogue-box configuration
setter/saver. If I had more time... Actually, you shouldn't want to change
the configs very often, so this method isn't too bad. Changed the template
file so that the program fills in the version/date when it is run.


1.31	

Looks for File_0fb instead of File_fb, when searching for a file-type
sprite when the file-type is < &100.


1.32	

Compiled without function names in code, to make it slightly smaller. 


1.40	20 June 1993 

Can have multiple icons on the icon-bar, with independent root menus. 


1.41

Can have text under the icons.


1.42	28 June 1993 

If a directory has bit 6 of its Access atributes set, !DirMenu now displays
it as an application (i.e. looks for a wimp sprite with same name). This is
for compatability with FilerPatch, by Jens Ovesen.


1.43	4 July 1993 

The WIMP doesn't seem to invert text+sprite icons in the same way as normal
icons in menus, so I've padded all items with spaces, making highlighted
icons in the menu easier to see.


2.00	11 July 1993 

Now creates a menu for Filer windows, like !QuickDir. This is done by
attaching a filter to the Filer which sends !DirMenu an event_CLICK when
Alt-Menu is clicked on a filer window. 


2.10	13 July 1993 

Opens a menu when there is a menu-click on the filer window title bar. I
think this is a lot more convenient than going to the keyboard to press
<Alt>. Couldn't use a filter for this because menu-clicks on title bars don't
seem to be passed on to apps by the Wimp. Hence had to make a module which
claims OS (not Wimp) mouse button events, and sends event_CLICK's to DirMenu. 


2.11	13 July 1993 

Opens a Filer-window menu for both cases - menu on title bar, and alt-menu on
workarea. !MakeMod makes a single module which acts as a filter on the Filer,
and also catches mouse events. 
I Couldn't use mouse-event-detector for the Alt-Menu case because the filer
would flash open its menu just before DirMenu opens its menu. 
!RunImage runs the Basic prog '!MakeMod' after it has initialised as a task.
!MakeMod then assembles the module, called DirMenuMouse, assembling in the
Filer and DirMenu task_handles. When DirMenu is quit, it RMKill's the module.
Assembling a module every time DirMenu is run is a bit clumsy, but I am a
new-comer to ARM assembler, so a module that actively finds the relevant task
handles (like in !QuickDir) is a bit too advanced for me. My method makes for
a smaller module anyway, and anyway Acorn have gone to the trouble of
including an assembler on every machine, so I might as well take advantage of
it! 
I don't know of any way of preventing the Wimp from seeing a mouse click.
This caused a few problems when making DirMenu respond to non-Wimp events
from the module. Any suggestions ?


2.20	14 July 1993 

Uses a simple Wimp_Poll loop instead of DeskLib's Event_ functions, which are
a bit of a luxury in such a simple program. This makes !RunImage nearly 5k
smaller. However, it still can't fit into a 32k wimpslot.


2.21	18 July 1993	*** third release *** 

Can set DirMenu to expand all system variables in file-paths prior to
Filer_Run-ing them. This is for when iconbar icons are specified to use
system variables such as <Wimp$ScrapDir> or @. It makes file/application
windows contain the full path name of the files that are clicked on. This
just uses SWI "OS_FSControl" with r0=37.


2.22	27 July 1993 

Oh dear! The click-on-Filer-titlebar thing seems to be a bit wobbly. Changes:
1.	Detects true menu button click i.e. buttons 000 -> 010, rather than
	xxx -> y1y. 
2.	When opening a Filer-window menu, the main program now rechecks that
	the pointer is over a titlebar, as a drag closely followed by a menu
	click on a workarea seem to result in Wimp_GetPointerInfo returning
	the poition of the start of the drag i.e. a titlebar. This resulted
	in spurious menu opening sometimes. Unfortunately, if you now move
	the pointer away from a titlebar very quickly after clicking menu,
	this modification may mean that DirMenu won't open a menu. 
3.	In !MakeMod, changed SWI calls to have 'X' bit set, and return if the
	SWI signals an error. The normal OS default error handling can give a
	horrid crash when using MemFS's non-multitasking 'free' window. I
	don't think this is my fault, as the OS error handling should cope
	with errors, and the SWI was Wimp_GetPointerInfo - hardly a
	complicated system-altering one. There was no problem with other
	non-multitasking windows.

Thanks to Kai Schlichting for noticing these problems.


2.23	13 Aug 1993	*** fourth release *** 

Mr Schlichting still gets spurious menus, and I'm a bit stumped by them. I
think part of the the problem is something to do with Wimp_GetPointerInfo
returning an out-of-date old mouse position just after a drag has taken
place, leading to DirMenu being told that a click occured on a title bar,
when it didn't. You can now make DirMenu only respond to Alt-Menu clicks in a
filer window, by altering 'Configs'. This removes the low-level code from
DirMenu's module. The two tiny Obey files 'TBar' and 'NoTBar' are needed
because Filer_Run doesn't allow you to send parameters to whatever it is
you're Filer_Run-ing. 


2.24	16 Aug 1993 

Copes with different Access bit used by Filer+ 1.13. Doesn't search for
#<spritename> etc yet.


2.25	5 Sep 1993 

A few small improvements: 

1.	Treats image filesystems as directories, allowing you to look inside
	them, assuming ArcFS (or similar) is running. The old read-only ArcFS
	didn't support this, so I couldn't do it until now.
2.	Now shows correct Filer+ sprites in the top half of the Filer-window
	menu. 
3.	Objects which are hidden by Filer+ ( because bit 6 of attributes is
	set) are displayed with fainter text, but are still
	selectable.


2.30	6 Sep 1993 

Displays sprites like #<name> etc. for directories, applications and images,
according to the precedence rules used by Jens Ovesen's Filer+ 1.14.


2.40	20 Sep 1993 

Responds to Menu clicks on any window, such as an !Edit or !Paint window.
DirMenu uses Wimp_TransferBlock to read the (indirected) title of the window,
as it will typically be stored in another applications workspace. If the
initial part of the window title is a filename (i.e. most of the time),
DirMenu will display the contents of the directory belonging to the file,
otherwise it will be a directory, so DirMenu will display the contents of
this directory. If the window contains more than about 100 icons, DirMenu
will crash. This is because the SWI which finds the title of a window
(Wimp_GetWindowInfo) also returns all the icons in the window, and there is
no way of telling how many of these there are so you can't garantee there
will be enough space reserved... It seems crazy to me that there isn't an SWI
which returns a window's info *without* its icons. Please let me know if
there is (a RISC OS 3?) one that I haven't heard of.

Another problem occurs when Menu is clicked on the title of a Zap window. Zap
seems to store only the visible part of the window title, in order to
implement custom justification where the leaf of the path is always visible.
This means that DirMenu will sometimes only get part of the path when Menu is
clicked on a Zap window. 

As usual, you can alter Configs so that these clicks are ignored, if you find
these bugs a  problem. On the other hand, if you know of any solutions to
them, please tell me! 

I've got rid of the Obey files 'TBar' and 'NoTBar', because there are now
too many options to send to the Module-maker !MakeMod. I now use the system
variable 'DirMenu$Options' to pass the parameters to !MakeMod.


2.41	22 Sep 1993

OS_File (with r0 = 5) should return 0 in r0 if a file doesn't exist, but
sometimes it just gives an SWI error, so DirMenu now looks at the SWI error
flag before accepting a window title as a valid pathname. Previously,
Menu-clicking on a Zap window could make DirMenu open stupid menus. Also
explicitly closes any existing menu, using Wimp_CreateMenu with r1=-1, when a
title-bar click is detected, instead of waiting for the Wimp to do it. I
thought this might save a little time on slow machines.


2.42	29 Oct 1993

DirMenu quits with an error message if it finds it has tried to get title of
a window with more than 100 icons. This is because some of DirMenu's memory
will certainly have been overwritten, and this could have unpleasant
consequences if ignored.


2.50	29 Oct 1993

Can have a 'Set CSD' item in a window menu


2.51	31 Oct 1993

Can force a 'Set CSD' item to appear by holding down <Shift> while Menu 
clicking on the titlebar of a window.


2.52	11 Nov 1993

Uses modified RO3 version of Wimp_GetWindowInfo, which ignores any icons in
the window. Hence DirMenu doesn't quit if you click on a window with > 100
icons. Thanks to Clive Jones and Erik de Kort for telling me about this. (the
trick is to set bit 0 of R1 when calling Wimp_GetWindowInfo. R1 points to the
block of memory reserved for the window information, which is word aligned so
the bottom 2 bits are unused). Also stopped the closing of existing menus
(see v. 2.41) as I think this was giving strange 'Unknown OS_Module call'
errors.


2.53	18 Jan 1994

Improved the error handling when an item in an icon-bar menu was incorrectly
specified as (for e.g.) "DeskLib: *" instead of "DeskLib:*"


2.60	2 Feb 1994

Tidied up�the code generaly. 
Called 'TreeMenu' now. Albert Koelmans at the newcastle server stored it
under this name, and it sounds better that 'Dir(e) menu'! 
I tried to make the menus auto-scrolling, but failed miserably -Menus behave
like normal windows, but don't seem to respond to wimp messages. Also, they
don't seem to have a valid taskhandle
Changed to the format of the 'Configs' file, so that the help comments don't
take up so much space, and renamed it '!Configs'.


2.62	14 Feb 1994

I've just bought the PRM's  8) and found that when you have finished claiming
an event, you should call OS_Byte 13, *then* OS_Release. (I used to do it the
other way round.
Added the 'reverse mouse button' option, and the 'Set CSD with <Alt>. These 
were both requested by Dennis Howe ages ago, but I've only just got round to 
them.
!TreeMenu now tells you if an error occurred from the 'Filer_Run ...' or 
'Dir ...' command. This is useful if you try to set the CSD to a file.


2.70	21 Feb 1994

Finally managed to make the menus auto-scrolling.
The WIMP seems to use OS_Mouse to read the pointer position/button state,
so I tried intercepting this SWI, and returning a bogus click. This worked,
but requires a separate module with a SWI, and would involve coding a
buffer in order to fake button press + buton release. The solution I now
use is to add mouse events into OS_Mouse's buffer, using OS_Byte 138. The
PRM's say this isn't recommended, but if you must do this, you should
disable events while you are writing to the buffer, in case a real mouse
event (e.g. the user clicking) arrives when you are in the middle of adding
bytes to the buffer. 
I'm not quite sure why this is not reccomended, and I'm fairly certain
there isn't a cleaner way. Anyway, it all seems to work OK.
The scrolling isn't very smooth, and has only 2 speeds, but is still very 
useful.
