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
	the previously required update.

2000-03-09  Eric Melski  <[e-mail]>

	* entry.tcl: Added code to re-sync the -text option with the
	contents of the entry widget before doing configuration; this
	fixes [Bug: 4304].

2000-03-09  Sven Delmas  <[e-mail]>

	* tree.tcl: Disabled the update before the find withtag in the
	allnodes procedure. The nodes are apparently created delayed, so
	before this procedure is called, the program has to do an
	update. I don't do this in the procedure anymore, because it
	caused multiple updates, making the app slower.

2000-03-08  Sven Delmas  <[e-mail]>

	* tree.tcl: The new allnodes procedure was not handling the
	"current" tag correctly. This is now stripped of.

2000-03-07  Eric Melski  <[e-mail]>

	* button.tcl: Added check for -state flag, to initialize it properly.

	* entry.tcl: Changed to parseArgs/initFromODB format; added check
	for -text flag to initialize it properly.

	* labelentry.tcl: Changed to use parseArgs/initFromODB format.

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

	* spinbox.tcl: Added a call in setvalue to scan the current value into
	a float to trim out any 0 padding on the number (otherwise the zero's 
	make it look like octal to tcl, which chokes on numbers > 8)

2000-03-07  Sven Delmas  <[e-mail]>

	* passwddlg.tcl: Reenabled the <Return> binding to activate the ok
	button. 

	* dragsite.tcl: I added an extra protection into the _begin_drag
	procedure to guard against a motion event that (sometimes) arrives
	before the press event. This fixes bug # 4324.

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

	* spinbox.tcl: Removed LabelFrame from SpinBox (BACKWARDS
	INCOMPATIBLE) to speed creation; updated configure proc to use
	hasChangedX instead of hasChanged, as it didn't really need the
	values of the options it was checking.

2000-03-01  Eric Melski  <[e-mail]>

	* spinbox.tcl: Changed bindings to be on class SpinBox instead of
	BwSpinBox, and added class SpinBoxEntry to the bindtags of the
	SpinBox entry component.

	* configure.in:
	* pkgIndex.tcl: Bumped version to 1.3.0.

	* tree.tcl: Changed focus redirect to use {after idle} to avoid
	focus loops.

	* label.tcl: Added -bd 0 -highlight... etc to wrapper frame; moved
	class bindings to the frame instead of the component label.

	* utils.tcl: Added helper function BWidget::refocus, to handle
	focus redirection calls.

	* spinbox.tcl: Changed focus redirect to use {after idle} to avoid
	focus loops.

	* combobox.tcl: Changed init to parseArgs/initFromODB style;
	changed focus redirect to use {after idle} to avoid focus loops.

2000-02-29  Eric Melski  <[e-mail]>

	* widget.tcl: Added bits to handle
	$path#subclass_that_inherits_from_other_bw_class megawidget names.

	* passwddlg.tcl:
	* progressdlg.tcl: 
	* progressbar.tcl: Changed init to parseArgs/initFromODB style.
