	**** BWIDGET 1.4.1 TAGGED ****

	* README.txt: 
	* configure.in: 
	* pkgIndex.tcl: up'ed version to 1.4.1

	* listbox.tcl: corrected use of 'end' as move index. [Bug #561391]
	* buttonbox.tcl: 
	* tree.tcl: force frame -padx/-pady to 0 to handle 8.4+ frame
	padding options. [Bug #545119]

	* scrollframe.tcl: corrected scrollregion configuration on
	Configure of frame to use full width/height of canvas when the
	canvas is larger.  This ensures that scrolling "anchors" properly
	to topleft.

	* dialog.tcl: prevent dialog from freezing on Windows with tkwait
	visibility on withdrawn toplevels. [Patch #521386] (chevreux)

	* font.tcl: reworked loadfont to not sort font names unless
	requested.  [Patch #524353] (kienzle, hobbs)

	* panedw.tcl: corrected handling of weighted panes following a
	Configure event. [Patch #513320] (decoster)

	* progressbar.tcl: Fixed display of vertical progressbar.
	[Patch #561403]

2002-05-29  Andreas Kupries  <[e-mail]>

	* combobox.tcl: Changed relief of popup list to ridge, for Win*
	  platforms.

2002-05-09  Andreas Kupries  <[e-mail]>

	* dynhelp.tcl: Accepted patch for bug 528929. Reported by
	  <[e-mail]>, patch also by him.

2002-04-25  Andreas Kupries  <[e-mail]>

	* notebook.tcl: Accepted patch for bug #532246, fixing the
	  appearance of the tabs so that text is always visible
	  completely.

2002-01-26  Pat Thoyts  <[e-mail]>

	* utils.tcl: Modified BWidget::place to support multiple screens
	under Windows. Better support would require Tk modifications.
	* demo/tree.tcl: Fixed for starting on secondary monitor under
	windows.
	* BWMan/BWidget.html: added documentation for BWidget::place.
	
2002-01-22  Jeff Hobbs  <[e-mail]>

	**** BWidget 1.4.0 tagged ****

	* widget.tcl: added Color as an optional type, with _test_color
	test.  [RFE #443124].

2002-01-15  Jeff Hobbs  <[e-mail]>

	* BWman/ComboBox.html: removed reference to label options that
	were removed when the LabelFrame was dropped.  [Bug #477130]

	* listbox.tcl: allowed drop handler to work in empty listbox.
	[Bug #456883]

	* mainframe.tcl: correct unprotected eval calls.  [Patch #501210]
	(chevreux)

2001-12-28  Jeff Hobbs  <[e-mail]>

	* BWman/Dialog.html:
	* dialog.tcl: Added '-transient' and '-place' flags.
	[Patch #483838] (decoster)

	* BWman/Tree.html:
	* tree.tcl: Added a 'recursive' argument to 'Tree::opentree' and
	'Tree::closetree'. [Patch #483838] (decoster)

	* BWman/ProgressBar.html:
	* progressbar.tcl: Added new type 'nonincremental_infinite' and
	modified movement of progressbar when in 'infinite' or
	'nonincremental_infinite' mode. The 'nonincremental_infinite' can
	be used when a certain process monitored by a ProgressBar returns
	a total count and not an increment count. [Patch #483838] (decoster)

	* BWman/PanedWindow.html:
	* panedw.tcl: Added '-weights' flag with possible value 'extra' or
	'available'.  Since BWidget-1.3.1, the meaning of the '-weight'
	flag for the 'PanedWindow::add' command was changed. This made it
	difficult to create a layout where the panes occupy a certain
	amount of the screen. When using the '-weights extra' flag when
	creating a PanedWindow widget, the >=1.3.1 behavior is used: the
	weights for the different panes are only used for extra space.
	When using the '-weights available' flag, the weights for the
	different panes are used to set the size of each panes relative to
	the total available space. [Patch #483838] (decoster)

	* BWman/ListBox.html:
	* listbox.tcl: Added '-selectmode' flag and 2 possible
	select-modes: single and multiple. [Patch #483838] (decoster)

	* widget.tcl: Select element 4 (was 3) from the config-options to
	get value from optiondb. [Patch #483838] (decoster)

	* utils.tcl: added else case to place is called with location
	different from 'at' and 'center' and without a parent.
	[Patch #484123] (decoster)

	* mainframe.tcl: added options -menubarfont, -menuentryfont and
	-statusbarfont at creation time of the widget as well as
	subsequent configures. [Patch #479935] (chevreux)

	* listbox.tcl: added multipleinsert command to allow faster
	inserts of multiple items. [Patch #458446] (chevreux)
	* widget.tcl: added Widget::copyinit. [Patch #458446] (chevreux)

	* BWman/NoteBook.html:
	* notebook.tcl: added options for enhanced tab shape in notebooks.
	[Patch #402466] (haneef)

	* configure.in:
	* pkgIndex.tcl:
	* README.txt: bumped version to 1.4.0 (not released)

	* mainframe.tcl (_create_menubar): start tagstate initially on.
	[Patch #470273] (chevreux)
	(_parse_accelerator): improve F* function key accelerator support.
	[Patch #444172] (venski)

2001-10-14  Jeff Hobbs  <[e-mail]>

	* pagesmgr.tcl: reverted fix of 2001-10-11 - it was bogus.

2001-10-11  Jeff Hobbs  <[e-mail]>

	* pagesmgr.tcl: allowed the ability to specify page by name,
	not just number.

2001-09-11  Andreas Kupries  <[e-mail]>

	* notebook.tcl: Removed 'Canvas' from the list of bindtags for the
	  internal canvas to prevent interference from application
	  specific bindings with our special widget. [459033].

2001-09-06  Andreas Kupries  <[e-mail]>

	* passwddlg.tcl: Accepted change by Bastien Chevreux
	  <[e-mail]> adding a -logineditable option to
	  the password dialog. [436340].

2001-09-05  Andreas Kupries  <[e-mail]>

	* panedw.tcl: Added option -activator to allow user to choose sash
	  activator. Reduced minimum allowed sash width. [442474]. Request
	  made by Bastien Chevreux <[e-mail]>.

	* label.tcl: Corrected typo in BWlabel::configure [454505], report
	  and fix by Bastien Chevreux <[e-mail]>.

	* arrow.tcl: Changed containing frame to be more invisible
	  (borderwidth 0). Fixes [458301], by Georgios Petasis
	  <[e-mail]>.

2001-08-08  Andreas Kupries <[e-mail]>

	* tree.tcl (Tree::_keynav): Added code to call the open and close
	  commands when the open-status of a node is toggled with the
	  space bar. Bug [449284].

	* color.tcl: Added the missing definition of the main
	  'SelectColor' procedure. This prevented users from creating
	  these widgets in the documented way. Bug [449276].

2001-06-21  eric melski  <[e-mail]>

	* tree.tcl: Corrected keyboard navigation so that open/close
	commands are invoked when right/left arrows are used to open/close
	nodes, patch from [Bug #435097].  Also corrected keyboard
	navigation on right arrow press; previously only opened closed
	nodes that had children, but should always open nodes, regardless
	of whether it has children.

2001-06-11  Jeff Hobbs  <[e-mail]>

	* pkgIndex.tcl: bumped version to 1.3.1 and added Tk 8.1.1 package
	require as Tcl 8.1.1 is needed in certain core areas for the new
	string methods.

	* mainframe.tcl: corrected state interpretation.  It doesn't do
	exact argument matching, but it is consistent with the rest of
	BWidget.  [Bug #224476]

	* demo/demo.tcl: fixed demo script to run when called from
	another directory

	* messagedlg.tcl: corrected winfo exists call

	* listbox.tcl: fixed string compare call

	* combobox.tcl: added package require Tk 8.3.

	* passwddlg.tcl: 
	* xpm2image.tcl: 
	* mainframe.tcl: 
	* panedw.tcl: 
	* utils.tcl: 
	* entry.tcl: 
	* dynhelp.tcl: 
	* dragsite.tcl: 
	* color.tcl: added braces to expr where appropriate

2000-10-31  Dan Kuchler  <[e-mail]>

        * combobox.tcl: Added the '-exact' option to the 'lsearch'
        commands in the combobox code so that the correct index
        of items will be returned even when there are glob/regexp
        characters.

2000-10-10  Dan Kuchler  <[e-mail]>

        * dynhelp.tcl: Added the '-screen' option to the toplevel that
        is created to display the help text to fix a bug reported by
        Tupone Alfredo.

2000-10-01  Eric Melski  <[e-mail]>

	* notebook.tcl: Fixed typo in _draw_page that incorrectly placed
	images on tabs.

2000-09-17  Eric Melski  <[e-mail]>

	* widget.tcl (_test_boolean): Altered to return strictly 0 or 1
	(for false and true, respectively), rather than allowing the
	string booleans (false, true, off, on, etc).

2000-09-07  Sven Delmas  <[e-mail]>

	* mainframe.tcl: Fixed the typo of Alt (Atl) as reported in bug #
	6079.

2000-09-05  Eric Melski  <[e-mail]>

	* label.tcl: Corrected bindtags for BWidgets Label components:
	primary component widget now includes the megawidget pathname in
	its bindtags list, so that bindings on the megawidget pathname are
	applied properly.

2000-08-10  Eric Melski  <[e-mail]>

	* widget.tcl: Corrected a problem caused by the destruction of the
	special .#BWidget* widgets, which are used by BWidgets for some
	option value validations; formerly, if these were destroyed, it
	could confuse the BWidgets system's internal state, and creating
	BWidgets after destroying these helper widgets would throw an error.

2000-06-14  Dan Kuchler  <[e-mail]>

	* dialog.tcl
	* dropsite.tcl
	* dynhelp.tcl
	* scrollview.tcl: Replaced several catch {unset varname} calls with
	if {[info exists varname]} {unset varname}.  This avoids using the
	catch, and also prevents the ::errorInfo corruption that was happening
	in BWidgets.

2000-05-14  Dan Kuchler  <[e-mail]>

	* tree.tcl: Fixed a typing error in the Tree::find procedure.
	The procedure wouldn't work because there was a 'llengh' where there
	should have been a 'llength'.

2000-05-08  Dan Kuchler  <[e-mail]>

	* titleframe.tcl: Added a '-state' flag that is associated to the
	state of the label.  Now that labels can be disabled (in 8.3 and
	beyond) this allows for the titleframe to have a disabled appearence.

2000-05-02  Eric Melski  <[e-mail]>

	* tree.tcl: Did some fancy focus footwork [Bug: 4491].  Now you
	can do this: "Tree .t ; bind .t <Button-1> foo", and it will do
	the right thing.  This will enable the use of proper
	focus-on-mouse-click bindings for trees, which in turn will fix
	the focus problem described in 4491.  In addition, I added a
	binding to the canvas widget in the tree that redirects focus when
	it leaves the canvas and goes to the frame, just in case.
	
	* dialog.tcl: Added a -geometry option, to allow the specification
	of geometry for the dialog.  No particular care is taken to
	validate the geometry string, so if it is bogus, you lose. [RFE:
	5188].

2000-04-27  Eric Melski  <[e-mail]>

	* entry.tcl: Added smarts to handle Copy for non-editable entries
	(it should be allowed, but was not previously) [Bug: 3755].

	* notebook.tcl: Small tweaks for placement of images on tabs.

	* combobox.tcl: Added code to ensure that non-editable (but
	enabled) comboboxes could still be tabbed in to.

2000-04-26  Dan Kuchler  <[e-mail]>

	* button.tcl: Fixed the bindings that get setup on buttons with
	an underline specified to be case insensitive (i.e  if 'A' or 'a'
	was the underline character, Alt-A and Alt-a would both be bound
	to the button.

2000-03-29  Sven Delmas  <[e-mail]>

	* tree.tcl:  Added protection for the left arrow key click in case
	we are already at the root node. This used to throw a Tcl error
	(fixes bug # 4619).

2000-03-20  Eric Melski  <[e-mail]>

	* progressbar.tcl: (configure) Added test for change to -maximum
	value, so that bar is redrawn if maximum changes. [Bug: 4399].

	* BWman/SpinBox.html: Removed references to -label* options.

	* demo/select.tcl: Removed use of -label* options on ComboBox and
	SpinBox. [Bug: 4394].

2000-03-14  Eric Melski  <[e-mail]>

	* button.tcl: (configure) replaced several hasChanged calls with
	one hasChangedX call.

	* dynhelp.tcl: (sethelp) replaced several hasChanged calls with
	one hasChangedX call.

	* entry.tcl: Replaced stack of hasChanged calls with one
	hasChangedX (in configure); replaced a couple cget's with
	getMegawidgetOption's.

	* spinbox.tcl: Updated _test_options to use setMegawidgetOption,
	and to only do that if it has to, instead of always doing it.

	* tree.tcl: Worked on itemcget; instead of upvar'ing the
	one-time-use variable, just refer to it directly.

	* widget.tcl: One problem with [set
	${class}::${path}:opt($option)] -- if path contains "foo(foo)",
	the command will choke.  Removed that particular
	micro-optimization.  Added setMegawidgetOption to compliment
	getMegawidgetOption; extended hasChangedX to accept multiple
	options to check.  This allows us to compress stacks of hasChanged
	calls into a single call (so there's a single function call, and a
	single upvar...).

2000-03-13  Eric Melski  <[e-mail]>

	* combobox.tcl: Tweaked bg/background options so that button
	didn't pick up entry background.

	* widget.tcl: Removed dead code; micro-optimizations to initFromODB.

	* tree.tcl: Added option for default -fill of tree nodes on windows.

	* notebook.tcl: Removed commented code.

	* button.tcl: 
	* tree.tcl: 
	* spinbox.tcl: 
	* entry.tcl: 
	* dropsite.tcl: 
	* dragsite.tcl: 
	* arrow.tcl: Replaced selected cget/getoption calls with
	getMegawidgetOption calls.

	* combobox.tcl: Removed LabelFrame from ComboBox (30% faster).

	* widget.tcl: Added getMegawidgetOption function, which allows
	direct access to megawidget-specific options (those that do not
	map to a component widget option).  This is dangerous, because it
	bypasses some checks, and it will only work with options that are
	specific to the megawidget.  However, it is much faster, and
	enables some functions (like visiblenodes) to be much faster.

	* tree.tcl: Reworked visiblenodes function to do a tree walk to
	find visible nodes.  This is faster and more correct than the
	previous implementation, which queried all the nodes in the tree
	for their open bit.
	

2000-03-10  Eric Melski  <[e-mail]>

	* widget.tcl: Replaced an upvar with a direct reference to the
	variable in initFromODB.

	* dynhelp.tcl: Changed sethelp function to use new hasChangedX
	function instead of hasChanged, which avoids an unneeded upvar,
	for a little better speed.

	* button.tcl: Changed to parseArgs/initFromODB format for a small
	(25%) speedup in creation time.

2000-03-10  Sven Delmas  <[e-mail]>

	* tree.tcl: Changed the allnodes procedure to visiblenodes, and
	also the mechanism of retrieving those nodes. This took care of
