changelog

是TCL的另外一个编译（解释）器

	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.

	* pkgIndex.tcl: Changed Label -> BWLabel

	* messagedlg.tcl: Changed initialization to parseArgs/initFromODB
	style.  Changed to use tk_messageBox on UNIX.
	
	* labelframe.tcl: Updated to use BWLabel instead of Label.

	* labelentry.tcl: Added -class LabelEntry to widget.

	* label.tcl: Changed class name to BWLabel (to avoid option db
	clashes with tk labels), changed initialization	to
	parseArgs/initFromODB style.

	* init.tcl: dropped obsolete Tree option from init.

	* dialog.tcl: changed initialization to parseArgs/initFromODB style.

	* notebook.tcl: Added -bd 0 -highlightthickness 0 -relief flat to
	the notebook container frame so geometries are correct.

	* entry.tcl: Fixed a conflict with configuring the Entry -text and
	textvariables.

	* dialog.tcl: added a -class option to the dialog, to allow the
	class of the dialog to be set (this enables proper optiondb use
	for things like the PasswdDlg).

2000-02-28  Eric Melski  <[e-mail]>

	* widget.tcl: Added Widget::varForOption function, which returns a 
	variable name that can be used to trace changes to an option for a
	particular megawidget (such as the -values option of a combobox).
	
	* entry.tcl: Made cget -text a little more efficient by
	shortcircuiting in that case.

	* combobox.tcl: Fixed bug #4248 by making the listbox use a
	-listvariable instead of trying to micromanage the listbox contents.

	* tests/entry.test: tests for the Entry widget.

	* widget.tcl: minor code cleanup.

	* tree.tcl: Was not getting proper default bg color on Windows,
	and keyboard navigation was goofy because of internal structure
	changes.

	* entry.tcl: Fixed an issue with initial foreground color not
	being picked up correctly.

2000-02-28  Sven Delmas  <[e-mail]>

	* tree.tcl: Added a procedure called "allnodes" to retrieve the
	names of all currently defined treenodes. Apparently the internal
	widget structure of tree was changed recently. I adjusted the
	"allnodes" procedure to that.

2000-02-25  Eric Melski  <[e-mail]>

	* combobox.tcl: Fixed a problem with non-editable comboboxes and
	selecting values.

	* arrow.tcl: 
	Fixed a problem with the invoke method (doing one too many winfo
	parents in some cases)

	* button.tcl: 
	* buttonbox.tcl: 
	* combobox.tcl: 
	* dialog.tcl: 
	* dynhelp.tcl: 
	* entry.tcl: (also fixed validation)
	* label.tcl: 
	* labelframe.tcl: 
	* listbox.tcl: 
	* mainframe.tcl: 
	* notebook.tcl: 
	* pagesmgr.tcl: 
	* panedw.tcl: 
	* progressbar.tcl: 
	* scrollview.tcl: 
	* scrollw.tcl: 
	* separator.tcl: 
	* spinbox.tcl: 
	* titleframe.tcl: 
	* tree.tcl: Updated to new megawidget architecture.

	* widget.tcl: Changed internal architecture.  When possible,
	megawidget options are stored in component widgets instead of in
	an intermediary array.  Also, made use of option database to make
	megawidget creation more efficient.

2000-02-24  Eric Melski  <[e-mail]>

	* LICENSE.txt: Removed LGPL license; added Tcl-license terms.

2000-02-23  Eric Melski  <[e-mail]>

	* widget.tcl: Replaced _test_boolean function with a more efficient
	implementation.

2000-02-18  Eric Melski  <[e-mail]>

	* images/target.xbm: Placeholder for actual icon.

	* color.tcl: Change env(BWIDGET_LIBRARY) to ::BWIDGET::LIBRARY;
	changed proc "dialogue" to "dialog"

	* pkgIndex.tcl: Updated function spec for color.tcl.

	* widget.tcl: Various minor speed tweaks; added a reverse mapping
	from component widget options -> mega-widget options so that
	subcget can be faster.

	* entry.tcl: 
	* dropsite.tcl: 
	* dragsite.tcl: 
	* arrow.tcl: Tcl list'd the specs for Widget::declare calls.

	* combobox.tcl: Removed extraneous ListBox::use call.
	

2000-02-17  Eric Melski  <[e-mail]>

	* notebook.tcl: Added an extra check to move the leftmost tab a
	touch to the right when it is not selected (again, to make the
	tabs more Windows-like).  Also replaced redundant [string equal]
	checks with a stored pre-check (ie, set foo [string equal ...]).

2000-02-16  Eric Melski  <[e-mail]>

	* notebook.tcl: Changed appearance of tabs; leftmost tab is now 
	flush with the left of the notebook, and the tabs look more
	Windows-like.

2000-02-16  Sven Delmas  <[e-mail]>

	* dialog.tcl: Added a new parameter to the draw procedure that
	allows me to pass in the desired geometry for the window. This was
	needed to support tracking of dialog window geometries.

	* tree.tcl: Changed the <KeyPress-space> binding to use "+", so it
	will not overwrite existing bindings (if there are any). Also
	added some extra protection in the keynav procedure against the
	user typing <Left> on a root node (this used to cause a stack
	trace).

2000-02-11  Eric Melski  <[e-mail]>

	* tree.tcl: Integrated changes from Eric Boudaillier:
	[itemconfigure -open ...]
	    optimized to only call redraw_idle 3 if node has subnodes.
	_cross_event:
	    itemconfigure -open called before -opencmd/closecmd; no more
	    call to _redraw_idle (handled by other procedures)
	_over_cmd:
	    allow position {root 0} when tree is empty
	new [find] command:  
	    [find @x,y ?confine?]
	    	    if confine is "confine" returns the node at window
		    coordinate x,y (x,y must be inside the bbox of the
		    node) else returns the node found on the line (in
		    pixel) pixel y
	    [find line]
	            returns the node on the line $line (in -deltay coords)
	new [line] command:
	    [line node]
	            returns the line where node is drawn
	-selectfill option added:
	    if true, selection is draw on full width of tree (instead of
	    just highlighting the bbox of the selected nodes)
	
	* combobox.tcl: Integrated changes from Eric Boudaillier:
	internal widget restructuring.

	* tree.tcl: Added "range" subcommand to selection.  Given two
	nodes, node1 and node2, it will set the selection to the visible
	nodes between (and including) node1 and node2.  If node1 or node2
	is not visible, it will find the first visible ancestor of the
	node and use that as the start/end point instead.

	* listbox.tcl: Integrated changes from Eric Boudaillier:
	_over_cmd: allow position 0 when listbox is empty
	find command, similar to tree find command.
	
	* spinbox.tcl: Integrated changes from Eric Boudaillier:
	cosmetic changes.
	
	* color.tcl: Integrated changes from Eric Boudaillier:
	split widget into two commands: SelectColor::menu and
	SelectColor::dialog.

	* progressbar.tcl: Integrated changes from Eric Boudaillier:
	added -idle option to prevent call to update in case where task is
	done in idle (ie, fileevents)

	* scrollview.tcl: Integrated changes from Eric Boudaillier:
	bindings changed.

	* scrollw.tcl: Integrated changes from Eric Boudaillier:
	-managed option: if true, scrollbar are managed during creation,
	so their size are included in the requested size of the
	ScrolledWindow.  If false, they are not.
	-sides option: specifies the side of the scrollbar.
	-size option: specifies size of scrollbar.
	-ipad option: specifies pad between scrollbar and scrolled widget.

	* mainframe.tcl: Integrated changes from Eric Boudaillier: support
	for function keys in accelerators, support for no modifier in
	accelerators.

	* notebook.tcl: Integrated changes from Eric Boudaillier:
	-internalborderwidth (-ibd) option specifies pad around pages;
	-foreground, -background, -activeforeground, -activebackground,
	-disabledforeground options for each tab.
	Code cleanup.

1999-12-23  Sven Delmas  <[e-mail]>

	* scrollw.tcl: Added "update idletask" to scrollbar update to
	prevent loss of update events.

1999-12-14  Sven Delmas  <[e-mail]>

	* combobox.tcl: When the selected item is changed, the selection
	is now set to the entire string.

1999-12-13  Eric Melski  <[e-mail]>

	* buttonbox.tcl: Added a getbuttonstate function, which retrieves 
	the value of a tag used on a button in the buttonbox.

1999-12-08  Eric Melski  <[e-mail]>

	* combobox.tcl: Removed code that cleared entry selection on focus out 
	events, as this crippled exportselection.

1999-10-29  Eric Melski  <[e-mail]>

	* buttonbox.tcl: Added a gettags function, which allows the user
	to query the tags that are used on buttons in the buttonbox.

1999-10-29  Eric Melski  <[e-mail]>

	* font.tcl: Added one new flag: -querysystem.  This lets the user 
	control whether the font selector queries the system 
	(via font families) for the list of fonts, or if it uses a preset 
	list of fonts (which is much faster and less likely to crash some 
	systems).

1999-10-25  Eric Melski  <[e-mail]>

	* font.tcl: Added support for two new flags: -families and -styles; 
	-families allows you to specify one of all, fixed, or variable, to
	limit the choice of fonts to those fonts; -styles allows you to
	specify a list of styles that can be set with the widget (ie,
	bold, italic, etc).

1999-10-22  Eric Melski  <[e-mail]>

	* tree.tcl: Fixed some problems with keyboard traversal.  Added
	support for left/right arrows a la MS Explorer.
	Added support for keyboard-based scrolling.
	
1999-10-21  Sven Delmas  <[e-mail]>

	* combobox.tcl: Added support for keyboard traversal.  The widget
	will now tab in even when it is not editable.  Also the entry
	widget content will be selected when the user tabs in. The key
	bindings now allow a traversal of the list (<Down> brings up the
	list). The arrow button no longer switches to an up button, but
	instead changes relief. The button is now more Windows NT like
	(for Windows NT).  Changed keyboard bindings:  down/up now
	display/hide the listbox; control-{up|down|prev|next} move through
	the options without displaying the listbox.
	
1999-10-21  Eric Melski  <[e-mail]>

	* tree.tcl: Added a -selectable option to tree nodes, which
	controls whether or not a given node is selectable (duh).  This
	works with the new -selectcommand option for the tree, and with
	keyboard traversal (also new).  Now, whenever the tree gets a
	"selection set", it calls the given -selectcommand with the name
	of the tree and the list of selected nodes, which makes it easier
	to just drop in place and use.

1999-10-15  Eric Melski  <[e-mail]>

	* panedw.tcl: Added a -class PanedWindow option to the main frame 
	(the megawidget) of the paned window.

1999-10-15  Eric Melski  <[e-mail]>

	* dialog.tcl: Added an overrideredirect option to Dialog::draw, which
	allows the user to control the overrideredirect state of the dialog.

1999-09-19  Eric Melski  <[e-mail]>

	* mainframe.tcl:  Fixed _destroy to unset ALL state variables, so that
	when a new MainFrame of the same name as an old one is created, it
	doesn't pick up residual state from the old one.

1999-09-17  Eric Melski  <[e-mail]

	* mainframe.tcl: Modified menu creation/setmenustate functions to
	support a new model of menustate.  Instead of enabling/disabling a
	menu item whenever any one of its tags changes state, now it only
	enables menu items if all of its tags are set.  This makes it
	really easy to, say, only enable the "New Action" entry if both a
	project is open and an element is selected.

	* buttonbox.tcl: Added tagging mechanism to buttonbox.  When using
	$bbox add, the first parameter is a list of tags for the button.  Then
	use $bbox setbuttonstate to change the state of a tag.

1999-09-16  Eric Melski  <[e-mail]>

	* notebook.tcl: Added some (non-functional) code for doing
	tab-notebooks with the tabs on the bottom.
