Short:    GUI creation library (small & fast)
Author:   P-O Yliniemi / Staffan Hämälä
Uploader: peoyli@algonet.se (P-O Yliniemi)
Version:  37.8
Type:     util/libs

This is the user distribution of GadUtil library. If you are interested
in developing programs that uses this library, you should get the
distribution from dev/gui on Aminet.

For advanced "normal" users:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Two versions of the library are included: one "normal" every-day-use
version and one "debug" version. If you experience any trouble running
a program that uses gadutil, you should rename the normal version in libs:,
copy the debug version to libs, and rename it to gadutil.library. Reverse
this to change back to the normal version. Don't forget to "flush" all
unused libraries or reboot before testing the program again.

Changes overview:
~~~~~~~~~~~~~~~~~
* 37.8  (15-Jul-96)
        Some bug fixes in the new help functions. If 0 was used as data on a GU_HelpText
        tag with a gadget that shows the help text in the window's or screen's title,
        there were some enforcer hits

        Deleted the separate autodoc files. Appended some information on the contents of
        the GU_Public structure to the autodocs. More info about SCRTITLE_HELP and
        WINTITLE_HELP was also appended.

        Changed the help function so that all gadgets and title bars that are used to
        display help strings is cleared if the mouse pointer is outside all gadgets that
        have help texts.

* 37.7  (12-Jul-96)
	Bug fix in the prototype for GU_ChangeStr (two parameters was mixed up).

	GU_ChangeStr now works for both STRING_KIND and TEXT_KIND gadgets. If the
	gadget isn't a STRING or TEXT gadget nothing is done.

	Bug fix in GU_CoordsInGadBox function. The register D3 was trashed in all
	earlier versions of GU.

	Three new tags allows any STRING or TEXT_KIND gadget to show a (localized)
	help text for each gadget in the window. These tags also works with the
	special gadgets (BEVELBOX, LABEL, PROGRESS). The gadgets attached to the
	window is scanned in sequential order. If a BEVELBOX_KIND gadget matches
	the pointer position, this gadget's help string will have the lowest
	priority. If another BEVELBOX is found inside this, the help string for
	that one will be used if there is no gadget inside that box. The help
	text can also be displayed in the window/screen title.

	The TEXT_KIND, STRING_KIND, NUMBER_KIND and INTEGER_KIND gadget's current
	value can now be read from the gu_Active field in the structure	that
	gg_UserData points to.

* 37.6  (15-Jun-96)
	gu_Active in the structure that gg_UserData points to was not updated
	when using any routine that used GU_SetGadgetAttrsA(). Now it checks
	the gu_Active value to see if it is out of the gadget's limits.

	gng_Flags and gng_GadgetText is now cleared before creation of every
	new gadget.

	The LAYOUTA_Spacing tag for LISTVIEW_KIND gadgets is now used to
	determine the height of the gadget. If the height of a gadget should
	be about 4 lines (GU_HeightFactor, 4), the height of the gadget is
	calculated to 4*(font height+value of LAYOUTA_Spacing tag). The same
	method is used for the GU_AddHeiLines tag.

	Hotkeys for LISTVIEW_KIND gadgets works as they should again. In v37.5
	of GadUtil (and probably some earlier ones), the listview didn't scroll
	down when you selected the next entry.

	Inserted pragmas and prototypes for tagcalls (pragmas only for SAS/C).
	It is possible to create stub routines for the tagcalls for other
	compilers by using fd2pragma 2.0.

	Inserted links to the include files in the index file for GadUtil.guide.

* 37.5  (29-May-96)
	Bug in PROGRESS_KIND gadget removed. If the gadget was set to
	show x/0 (also 0/0), a division by zero was done.

	Two new constants added to the include files: GADUTIL_VER and
	GADUTIL_REV.
	
	Bug fixes in test (demo) programs. The FPF_DISKFONT flag in the
	TextAttr structure was unset in all demo programs. Replaced the
	manual version check in the demo programs with the GadUtil function
	GU_CheckVersion. Removed unnecessary IDCMP flags from the demo
	programs and replaced GadTools IDCMP with the GU_MinimumIDCMP tag.

* 37.4  (14-May-96)
	Created a new gadget kind: LABEL_KIND. This gadget kind is used
	to place text relative to other gadgets, bevel boxes, and other
	texts. Can use the same type of shadows that the text for the
	bevel box.

	Implemented a new function in the library: GU_CloseFont. Works
	like graphics CloseFont, but takes the parameter in A0 instead
	of A1.

	Replaced the list sort routine with a new one that sorts better.

	Wrote a new document, "GadUtil.index", that have a list over all
	gadutil functions, sorted by what they do. There are also some
	shortcuts to all tags for gadutil's own gadget kinds.

	Created two new flags for BEVELBOX_KIND and LABEL_KIND:
	BB_3DTEXT - can be used as a replacement for GUBB_3DText, TRUE
	LB_3DTEXT - can be used as a replacement for GULB_3DText, TRUE

* 37.3  (10-May-96)
	Enforcer hits fixed in the code that handles the GU_AdjustLeft
	and GU_AdjustRight tags.

	A new function to clear the inner part of a window was added.

	A new function to size (and move, if necessary) a window was
	added.

	Bug fix in assembly language include file.

* 37.2  (02-May-96)
	Started programming in StormC and did some tests with the library,
	noticed that there was a couple of errors in some include files.

	GU_UpdateProgress was wrongly specified in the FD/clib files.
	The output of GU_GetGadgetPtr was specified as (struct Gadget *),
	this is now corrected.

	Included an example in C that uses the PROGRESS_KIND gadget.

* 37.1  (01-May-96)
	IMAGE_KIND gadget bug fix. The color of the unselected image of
	the gadget was wrong, if the image used more than 4 colors.

* 37.0  (29-Apr-96)
	A new function that checks the library's revision added.
	Two new tags added: GU_FractWidth and GU_FractHeight. Suggested
	by Morten Amundsen.

	Some small bug fixes in 'C' include files (unterminated comments).
	Cleaned up BetterTest.c a bit (removed some {}). Bug fix on the
	last line of the example (GT_ReplyIMsg -> GU_ReplyIMsg).

	Added support for StormC in both installer script and include-
	file installer. Created dictionary for StormC, so that all words
	that belongs to GadUtil (functions, tags and constants) is shown
	in another color.

* 36.60 (24-Feb-96)
	Uses the screen's font as the gadget font if no GU_DefTextAttr or
	GU_TextAttr tag is used. Bug fix from v36.59. Changed some docs,
	assembled all examples,	changed installation scripts.

* 36.59 (06-Jan-96)
	More docs completed (all docs, finally). Bug fix in the GU_AutoWidth,
	GU_AdjustLeft and GU_AdjustRight tags. The underscore character was
	counted as a normal one. This made gadgets without hotkeys one char
	smaller than other gadgets. A new function that sorts one or two
	lists was added. Some new constants added in include files.
	Changed GU_MinimumIDCMP to support hotkeys. Changed PROGRESS_KIND
	to use GU_GadgetText and GU_LocaleText. Uses the screen's font as
	the gadget font if no GU_DefTextAttr or GU_TextAttr tag is used.

* 36.58 (01-Jan-96)
	SLIDER_KIND and SCROLLER_KIND gadgets returned wrong result in
	im->Code if the gadget was changes using the hotkey. Bug reported
	by Lucasz Szelag.

* 36.57 (10-Dec-95)
	Some more docs finished. A memory loss bug was fixed.

* 36.56 (10-Oct-95)
	Changed some routines, so that hotkeys can't be used on disabled
	gadgets. Made it possible to disable IMAGE_KIND, FILE_KIND and
	DRAWER_KIND gadgets.

* 36.55 (30-Sep-95)
	Bug fix in the hotkey part of the library. Wrong code were sent back
	when using GU_LabelHotkey with a LISTVIEW_KIND gadget. A new gadget
	kind was created, PROGRESS_KIND.

* 36.54 (06-Jul-95)
	Added support for GU_AutoWidth to CYCLE_KIND gadgets.

* 36.53 (05-Jul-95) 
	3 new tags and 4 new flags was added for the BEVELBOX_KIND gadget.
	BEVELBOX_KIND gadgets can now have a shadow added to the text in the
	border. The "sun" can be placed in 4 different places. GU_MinimumIDCMP
	tag was added.

* 36.52 (25-Jun-95)
	First public release. Some new flags for the BEVELBOX_KIND gadget was
	added. Supports a total of 100 bevelbox kinds.
