ChangeLog for Visual Tcl:

1.6.0a1 -> 1.6.0a2
    o Fixed tooltips bindings bug.
    o Added tooltip option to checkbutton, radiobutton, message, scale,
      text
    o Megawidgets editor does not allow to delete the last subitem
      (eg. the last column, or the last page in a tabnotebook)
    o Added BLT Bar chart widget
    o Namespace'izing widgets for cleaner code
    o Saving suboptions for megawidgets according to checkboxes.
    o For megawidgets, saving checkboxes for saving suboptions or not.
    o Fixed bug where setting geometry padx/y option would set regular
      padx/y option for button widget.
    o If "autoload compounds" option is on, but file is not found, option
      is turned off.
    o If "autoload compounds" option is on, but no file has been specified,
      asks for a file. If user cancels file selection dialog box, autoload
      compounds option is turned off. If user specified a file, it is
      saved in the preferences.
    o Fixed dump format bug where it would trim the first line of a proc.
    o Open/Save file dialog box now uses the title it is passed as a
      parameter.
    o Fixed problem with .vTcl.con being renamed to .vTcl.tkCon
    o Added widget path to bindings editor
    o Bindings editor now enables insert button and insert menu when
      selecting a widget
    o Made insert advanced binding dialog modal, added buttons at the
      bottom of the dialog the way it should be for modal dialogs
1.52 -> 1.6.0a1
    o Editing for tixPanedWindow.
    o Fixed scrollbar bug, when right-click / Attach to widget
      wouldn't save the -command and -x/yscrollcommand options into
      the project.
    o Right-click menu to edit Iwidgets toolbar
    o Added icons for vertical/horizontal panedwindow in IWidgets
    o Set reasonable defaults for scrollbar width/border under Unix
    o Toolbar can now be resized
    o Support for scrolled window and scrolled frame in BWidgets
    o Support font option in menu editor.
    o Fixed closing brace bug.
    o Added scrolledcanvas for [Incr widgets]
    o Editing radioboxes, checkboxes and buttonboxes
    o Support for %top and %widget in commands for megawidget subitems
      (eg. commands for a button in a buttonbox)
    o Fixed find/replace problem where replace string is a superset
      of find string.
    o Display asterisk in title bar to show that changes have been made.
    o Added BLT tab set.
    o Added BWidgets paned window.
    o Added a list of choices for the -cursor option.
    o Multicolumn listbox:
      - fix for -labelrelief option
      - dump columns into project
      - new columns option in attributes editor
    o Fix in compound code for copy/paste of BWidget notebook.
    o Again use raise command if tk >= 8.3.4 where the 2-second delay on
      some X Windows managers has been fixed.
    o Added support for BWidget combo box.
    o Modified notebook class of BWidget to use class bindings instead of
      widget bindings. This prevents saving bindings into the project.
    o Default insertion of three pages when creating new bwidgets tabnotebook.
    o Display of pages of bwidgets tabnotebook in attributes editor.
    o Dumping bwidgets tabnotebook in file.
    o Selection of tab/notebook pages from attributes editor.
    o Laying out the foundation for custom class options. Current custom class
      option is -_tooltip. Each custom class option has commands for config-
      uring and updating the option in the attributes manager.
    o Better and simpler implementation of action to take when focus lost in
      attributes editor. Now, when the user presses a key in an attribute, the
      command to execute is stored until either he presses Return or the focus
      gets lost. When the entry field loses the focus, the command gets
      executed.
    o Sorting names of packages in the system inspector.
    o If the package Img can be found, adds more file types to the image
      manager: JPEG, BMP.
    o Shift-click will now place the last widget placed.  This sort of bombs
      the shift-click scrollbar feature, but since it's in the widget menu
      of the scrollbar, we don't really lose functionality.
    o Removed the quit confirmation when exiting.
    o Added a preference option for Widget Tree highlight color.
    o The command window remembers where it was and saves.
    o Made news return immediately and fetch in the background so that vTcl
      doesn't hang while waiting for news to come back.
    o Fixed saving bug introduced when adding "save position" and "save size"
      options for toplevels. This broke projects with Iwidgets childsites.
    o Saving balloon help code with conditional statement so it does not get
      reloaded into vTcl.
    o A bit of cleanup.
    o Added "ClassOption" command to define special options on a class basis.
      For example, labels can have tooltips, tabbed notebooks will have a
      combobox to select a page, toplevels will have a "module" option, and
      so on.
    o Added a few more images for BWidgets.
    o Removed support for Entry, Label and Button in BWidget until we find
      a way to distinguish these widgets from Tk widgets. Otherwise, this will
      break existing projects when they are resaved, by replacing their command
      from "entry" to "Entry" for example.
    o Added a bunch of options in the preferences to make Luke happy :-)
      - entry background color
      - entry active color
      - listbox background color
    o Background color in preferences uses BWidget color selection.
    o Default font for Windows now {MS Sans Serif} 8. Default font for Unix
      is Helvetica 12.
    o Tooltip option still hardcoded now but custom options will eventually be
      programmable. Added special registration proc to register options not
      available with configure.
    o Fix to allow saving projects using the ::blt::busy command (not the most
      elegant one but the easiest one that required the less retesting)
    o Using the BWidget font selector
    o Support for dump/copy/paste of Iwidget optionmenu
    o Added patch from Don Porter <dgp@users.sourceforge.net> to support Tk8.4.
      This is a short term solution until we stop using internal Tk variables
      and commands.
    o Added "Do not show news on startup" checkbox
    o Support for copy/paste in itcl toolbar, buttonbox, checkbox, radiobox
    o Trying to compute approximate height of preferences dialog based on
      dialog font and a hidden radio button. Seems a good compromise.
    o Set font for notebook widget to vtcl dialog font so it looks uniform.
    o Added tooltip text property in attributes window.
    o Done a bit of compacting in some library routines.
    o Preparing support for balloon help in projects by making all balloon
      help code self contained in a binding tag. This way, to set the balloon
      for a widget, the _vTclBalloon tag should be added, and for the widget,
      the <<SetBalloon>> event should be defined with the following
      code: "set ::vTcl::balloon::%w {balloon help text}". Will add support
      for property manager soon.
    o Goal to have balloon code in a binding tag: support for copy/paste,
      very few changes to code generation, backward compatible with 1.5.2
    o Made code to dump procedures/functions more uniform.
    o Added "foreach" body support to stack trace window.
    o Repaired problem with new project generating error on save.
    o Saving geometry with or without position and size, depending on
      "set origin" and "set size" properties.
    o Added "set origin" and "set size" option to toplevels. To be
      saved in the project soon.
    o Fixed what Damon broke in the toplevel list :-)
    o Added vTcl(pr,entryactivecolor) preference to set the bgcolor when
      the mouse pointer is over entry fields.
    o Renamed vTcl(propmgr,relief) to vTcl(pr,proprelief) so it gets
      saved in .vtclrc, and the user can change it to his liking
    o Operation cleanup: insert commands for widgets no longer return
      a string to execute. Instead, the insert proc is run with the target
      as a parameter.
    o Moved all insert cmds to their individual widget files where they
      belong.
    o Added default scrollbar size of 14 for Linux/Unix users. For some
      reason when using pack/grid, nice scrollbars with a width of 10
      having a border width of 2 have a total width of 14. But, using the
      place manager (which BWidget seems to be using with the scrollbars),
      the width option encompasses both the width of the draggable bar plus
      the width of the border. To summarize, scrollbars with of width of 10
      that are packed or gridded look exactly the same as scrollbars with
      a width of 14 that are placed (ok, you get it now?).
    o Removed extraneous option database entries that we define already.
    o Fixed a bug in the system inspector where some windows would not have
      a widget procedure and would not respond to the standard configure
      command. This happens for some special temporary windows created by
      BWidgets.
    o Removed the container thing for toplevels. The idea was to create
      one toplevel for each page of a tabnotebook and then call the toplevel
      creation proc with a special parameter to put the widgets inside the
      tabnotebook's pages. Since we now allow direct editing of tabnotebook
      pages this feature becomes no longer necessary.
    o Removed a bunch of borderwidth options in the property manager to
      use standard values. If we want different values we should use the
      option database instead of hardcoding them for each single widget.
    o Added a "New Project Wizard" that appears when a new project is
      created.  Still in the fledgling stages, but it's there.
    o Better way of exiting a user app. When toplevels are created, a count
      is maintained. When count goes back to zero, application exits. Defined
      a special binding tag for this.
    o Removed vTcl:WindowsCleanup no more needed because of above mechanism.
    o Readded call to vTcl:raise in tkCon initialization
    o Bound the entries in the attribute editor to change color with focus
    o Removed call to raise in console.tcl to speed painting of tk_con in KDE2
    o Removed vTcl:show_console in KDE2
    o Modified vTcl:attrbar:toggle_console to run ::vTcl::InitTkcon only one
      time and to do the work of vTcl:show_console
    o Made a fix that I hope will fix the cursor problem.
    o System inspector shows window class in left pane
    o Widget tree now uses "dialog font" from the preferences.
    o Cleaned up alias definitions in bindings editor too.
    o Toplevel now links the WM_DELETE_WINDOW protocol event to the
      <<DeleteWindow>> virtual event.
    o Option for dialog font now works using the option database, allowing
      to change the font for the entire application
    o Option for fixed font also works using only option database
    o More cleanup for alias definitions.
    o Added basic support for more BWidgets.
    o Fixed bug where handles would sometimes appear on the toplevel window.
    o Added propagate patch from Simon for pack/grid geometry managers.
    o Added call to tk_setPalette to set color scheme according to
      preferences.
    o Fix for correctly dumping labeledframe with contained widgets.
    o Added wheel mouse support to the property manager.
    o Cleaned up some of the BWidget support.
    o Added Escape and Return key bindings to preferences window.
    o Added more tests to automated test script.
    o Restored vTcl:exit stuff like it was in 1.5.2 because vTcl
      wouldn't exit if the command console was open. Need to figure out how
      to make the exit command work inside the command console.
    o Set highlight color to what the preference is.
    o Cleaned up the tk_strictMotif code.  Added a ::vTcl::MessageBox proc.
    o Replaced all instances of Ok buttons with the ::vTcl::OkButton command.
    o Replaced all instances of Cancel buttons with the ::vTcl::CancelButton
      command.
    o If a toolbar button, label or menubutton is disabled, it will not
      raise when the mouse passes over it.
    o Using transparent GIF images.
    o Added background color tab in preferences.
    o Message boxes don't use tk_strictMotif

1.51 -> 1.52
    o Fixed startup bug

1.51b4 -> 1.51
    o Filter dynamically created proc for progress bar widgets
    o Used uplevel instead of eval for evaluation of scrollbar command in
      multicolumn listbox
    o Replaced vTcl:dialog by tk_messageBox everywhere.
    o Modified demo app Visual Text to support tag names with spaces.
    o Fixed problem when Tcl/Tk 8.3.3 from ActiveState passes a {} parameter
      to the command line causing Visual Tcl to fail on startup
    o Added code to dump a toolbar with its components.
    o Don't allow inserting into widgets that are not part of the widget tree
    o Fixed bug where combobox/mclistbox/progressbar code wouldn't be
      saved with project in some situations
    o File Open/Save remembers last directory
    o Added "-listvariable" option for listbox
    o Added "Reload" button to image manager, to reload images modified
      by other programs like image editors.
    o Added <<Ready>> event for toplevels
    o Added <<Create>>, <<Show>> and <<Hide>> virtual events for toplevels.
    o Updated demo app with these virtual events.
    o Removed (pre) and (post) mechanism for toplevels.
    o Added GPL copyright for Tk widgets description files.
    o Fixed find/replace bug with dollar sign in text to find.
    o Find/Replace highlights text when a match is found.
    o Fixed bug when copy/paste widgets with non-standard binding tags
    o When a toplevel is destroyed, refresh the bindings editor
    o Added bitmapbutton compound and test app in demo folder
    o Added toolbar buttons to visual text application
    o Added horizontal scrollbars to command and proc editors
    o No need to remove duplicates from the MRU list, because when a file
      is added to this list, the code checks if the file already exists in the
      list and removes it if needed, then adds it at the top of the list.
    o Fixed bug where Tclets with pack or grid manager wouldn't run because
      of wrong window path
    o Simplified a bit demo app by removing alias for main window
    o Fixed bug with %top substitution for menu items
    o Automatically assigns a default variable for entry and scale widgets
    o Added same %widget and %top mechanism for menu commands; this allows a
      menu to know in which toplevel it is located, or to reconfigure itself
      if needed
    o Fixed bug where binding tags would all of a sudden disappear from a project
      after bindings editor is being displayed.
    o Added Ctrl + N, Ctrl + O, Ctrl + S, Ctrl + Q and F1 keyboard shortcuts
      to demo application VisualText
    o listbox and text widget on creation take default values for -font option
    o new text widgets have a white background
    o replaced %W by %widget for command options, to avoid
      conflicts with %W from the bind command
    o -command options can have substitution strings:
      %W will be replaced by the widget path
      %top will be replaced by the toplevel path
    o Now checks for Tcl/Tk 8.3 version or higher
    o Saves -variable with namespace as $base\::variable instead of .top22::variable
    o Sets default -variable for checkbutton and radiobutton
    o Added 'Insert image...' menu item to VisualText
    o Replaced 'wm withdraw .top22' by 'wm withdraw $base' in saved project
    o Added Shift + Click functionality to scrollbar to link to table widget
    o Namespace'ized demo application VisualText
    o Added 'About' box in Visual Text
    o Now dumps procedures with a header including procedure name
    o Added - to characters for commands in syntax colouring
    o Fixing _ problem in toplevel names when saving projects with scrollbars
    o Toplevels are now automatically assigned a namespace with the window
      path, allowing the user to save his data inside. For example, a window
      named .top22 will be assigned a ::.top22 namespace while a window named
      my_own_window will have a ::my_own_window namespace. It is recommended
      to use this namespace to store variables like check box variable, radio
      box variable, etc.
    o Fixed a few tix bugs: tixFileEntry, tixScrollHList
    o Added -fillcolor option to tixMeter
    o Fix cursor bug on insert if clicking too fast
    o Fixed bug where closing menu editor wouldn't save changes
    o Fixed aliases bugs in menu editor
    o Removed a few unused variables in menu editor
    o Made toplevel menus flat
    o Added <Destroy> to simple bindings menu
    o Removed <<TkCon*>> bindings from binding editor
    o Added demo application 'visual-text.tcl' using Bryan Oakley's
      code to dump an entire text widget contents into a file
    o Prevent the same alias from being defined in two toplevels
    o Center alias dialog and command dialog if no widget has been
      selected using the mouse (it is possible to select a widget in
      the widget tree)
    o Use as many default values as possible for new menu widgets
    o Fixed bug where Visual Tcl would switch the manager for a menu from
      'wm' to 'place'
    o When moving menu items up and down, selects item at new position
    o Adopted Interned Explorer-like toolbar buttons for a much nicer look
      (well, that's my opinion at least)
    o Fixed lremove bug in bindings editor
    o Added more default values to scale and message widget, to avoid
      saving them in the project when not needed.
    o Updated tix panedwindow and notebook to save childsites using
      relative paths (eg. asking the megawidget the path to its childsites
      instead of hardcoding it in the project)
    o Found how to dump scrollbars with childsites to avoid absolute
      widget paths.
    o Made sure not-to-be-saved options won't be saved again after a
      project is reloaded.
    o Fixed bug for right-click context menu "Hide" doing nothing for
      toplevels.
    o Do not use the raise command on Linux, because it is too slow
      (2 second delay waiting for faulty X-Windows implementation to
       respond to message)
    o Fixed balloon help already existing window bug.
    o Cleaned up dumping megawidgets and their childsites. There are
      no more absolute paths, instead the code asks for each childsite
      in turn and stores its path into a variable. Still need to figure
      out how to save scrollbars with this new mechanism.
    o Fixed default options problem for megawidgets childsites.
    o Added code to select pages in tabnotebook and notebook widgets
      when selecting a frame in the widget tree
    o Made sure Visual Tcl doesn't change the manager for childsites!
      This was the "manager switches from pack to place" mysterious bug,
      which is actually not a Tk bug at all. What happened is when
      a widget is selected, if it is hidden, Visual Tcl tried to re-
      manage it using the default manager.
    o Unregister widgets (delete their namespace) when destroyed
    o Cleaned up the keyboard scrolling in the property manager.
    o Fixed a bug where options would get changed while scrolling in the
      property manager.
    o Fixed delete toplevel bug
    o Added support for deleting childsites in notebook/panedwindow (Tix)
    o Added support for deleting childsites in tabnotebook/notebook [Iwidgets]
    o Added notebook widget for Itcl. Supports copy/paste.
    o Common options like -background take their default values on project
      load unless, of course, the option is saved in the project
    o Support copy/paste for megawidgets tixPanedWindow and tixNoteBook
    o Megawidgets don't save their internal grid geometry
    o Added necessary compound code to allow copy/paste of megawidgets with
      childsites. Enabled tabnotebook and panedwindow [Iwidgets] with this
      functionality.
    o Fixed copy/paste bug where megawidgets would lose their options after
      saving.
    o Added code to prevent special IWidgets binding tags from beeing saved
      in the project.

1.51b3 -> 1.51b4
    o Now prevents the user from trying to assign the same alias to 2 or more
      widgets inside the same toplevel.
    o Added <Shift-ButtonRelease-1> command in the toolbar to auto-place widgets
    o Added column and row stretch options to tkTable library
    o When a toplevel compound is inserted, do not require the user to click
      anywhere, because this does not make sense. Instead, insert the compound
      directly.
    o Fixed copy/paste problem for toplevels.
    o Fixed "ask for widget name on insert" problem for toplevels.
    o When inserting a compound, widgets are registered one at a time as
      the compound is created, instead of after the compound creation. This
      allows default values for the widget to be known and applied when
      possible (see below).
    o When inserting a compound, widgets for which options aren't specified
      take their default values for the most common options like -background,
      -highlightbackground, etc. This reduces the size of saved projects.
    o Made the "-width" option for scrollbar widgets not saved by default (the
      user can still override the option by clicking on the checkbox next to the
      "-width" option)
    o Have the most common options like -background, -activebackground etc.
      take their default value when a widget is created, instead of using the
      value from the options database. This saves space when saving projects, and
      makes it easier to port them to other platforms.
    o Fixed "Set command" bug where it would prevent from saving the project
    o Made sure -label, -anchor and other options are saved
    o Fixed error when inserting compound for the first time after starting vTcl
    o The behavior for aliases in compounds is modified as such:
      - if there are aliases in the compound, define them when compound is inserted
        (so the alias will point to the pasted widget, not the original one, but
         because vTcl allows same aliases to exist in several toplevels, this is
         not a problem)
      - if there are no aliases for subwidgets in the compound, and the
        "Auto Aliasing for New Widgets" option is turned on, then new automatic
        aliases are created
      - if a compound is pasted into a toplevel with an alias that already exists
        in the same toplevel, then a new automatic alias is created
    o Added right-click menu in attributes editor to allow setting an option for
      a range of widgets at once, as well as to save/not save options and restore
      the default value for an option

1.51b2 -> 1.51b3
    o Usability improvements:
      - added "Set Variable" for checkbutton and radiobutton
      - added "Set Value" for radiobutton
      - added "Edit Menu" for toplevel
    o Cosmectic improvements:
      - regrouped toolbar buttons and close button in the same line in both
        the menu and the bindings editor
    o Tried to fix the not-totally-fixed cursor bug. Seems the
      ButtonRelease-1 gets processed before ButtonPress-1 returns,
      so if ButtonRelease-1 comes too soon, it is posted as an
      "after" job. This prevents the cursor from changing to "fleur"
      in some situations.
    o Widget tree keeps highlighting the selection after refresh
    o TkCon restores position on vTcl startup
    o Set string input dialog entry field to white background and
      changed OK / Cancel buttons to icons (checkmark and red cross)
    o Activating a widget now automatically scrolls widget tree into view
    o Fixed message text input dialog Escape bug
    o Added "Set Text Variable" context menu item to entry widget
    o Fixed problem where vTcl was saving duplicate fonts.
    o Fixed some bug where problems could occur from defining namespaces
      with a space in the name.
    o Deleting a menu in the widget tree refreshes an open menu editor
    o Deleting a toplevel menu closes a possibly open menu editor
    o Editing a submenu brings menu editor for root menu and selects
      submenu
    o Raised the labels on the property manager.  As each individual option
      is selected, the label becomes sunken.  This is a cosmetic change
      that is in place for a future enhancement.
    o Added scrolling through the property manager using direction keys.
    o Added Jeffrey Hobbs' TkCon as the default console on all platforms.
    o If you quit, it no longer asks you twice if you want to quit.
    o Cleaned up the import header code.
    o Cleaned up all the library import headers.
    o Tclets now save images as inline as well as font definitions
    o Added menu keyboard shortcuts in main window
    o Added keyboard accelerators where missing, eg. in bindings
      editor, menu editor, system inspector, image manager, font
      manager, you can use any of the standard Accelerators like
      Ctrl + Q, Ctrl + N, etc
    o Added code so that Ctrl + C, Ctrl + V, Ctrl + X, Delete do
      act differently if invoked from entry or text widget in
      a visual tcl window (eg. if you press Delete in an entry
      field inside the menu editor, it shouldn't delete the
      currently selected widget)
    o A few fixes to import vTcl 1.20-1.22 projects:
      - hidden toplevels are shown/hidden when importing a project,
        then they show up in the widget tree and get saved properly,
        including their aliases
      - when saving ignore aliases to non-existing widgets
      - when a hidden toplevel is shown for the first time, it gets
        registered
    o Fixed font saving bug not totally fixed in 1.51b2; adding
      and deleting fonts now works properly
    o Images are now saved with platform independent filenames
    o A few fixes for Macintosh compatibility:
      - made sure [file join] is used when loading widgets
      - made sure titlebars appear properly
      - changed button with pulldown menu to label in menu editor
      - "Save As..." dialog box doesn't use -filetypes on Mac
      - main window now resizes automatically, positions itself
        just below the Macintosh menu bar
    o Fixed menu dump bug (manager switches to place and
      project cannot be reloaded)
    o Added menus to bindings editor
    o Added menus to menu editor (sic)
    o Fixed "Delete" bug in menu editor
    o Adding a cascade in menu editor refreshes widget tree
      and activates widget
    o Fixed cursor bug (when user selected a widget with a different
      cursor then selected a toplevel, the toplevel was getting the
      cursor from the widget)
    o Added more credits in About box for combobox, multicolumn listbox
      and progress bar
    o Added support for labeledframe in Iwidgets

1.51b1 -> 1.51b2

1.22   -> 1.51b1
    o Added a configure script to locate the best WISH shell.
    o Changed the way libs are loaded

      necessary mclistbox or combobox code is included
    o Support for Iwidgets and BLT with new widget description mechanism
    o Megawidgets such as Iwidgets can now be selected/dragged as a whole
    o Added checkboxes to save only the options the user wants to.

      bindings, namespaces, packages
    o Completely redone the binding editor. Should be easier to use and
      less error prone (forgot to click on "update" ?)
	o Removed "type" as a means of identifying widgets.  Widgets are all
	  identified by class.
	o If you iconify/deiconify vTcl, it takes the toplevels with it.
	o Changed the default color for all vTcl windows to #d9d9d9.
	o Completely re-wrote the way widgets are defined.

	  would cause its manager to change, thereby breaking the project
	  the next time it was sourced.
	o When a project is saved, we save the hidden toplevel windows too,
	  we just don't show them again.  But, the next time we load the
	  project, they're properly included in the project and on the widget
	  tree.
	o Cleaned up the order in which widget selection occurs when a widget
	  is deleted or cut.
	o Added a menu option to Restore a project from backup.
	o revamped Preferences... dialog (cool no?)
    o added an option in the Preferences... dialog to save all images as
      inline using Base64. Allows for self contained projects without any
      dependencies on external images. However, while editing the project,
      external files are used as usual. When saving the project, external
      image files are then converted to Base64 and included inside the main
      file.
	o if a widget is of an unknown class, just ignore it, instead
	  of generating an exception
	o changed the way widget placement is handled.  It is now more like a
	  traditional GUI builder.  This can be turned off in the preferences
	  menu.

      "Multiple files project"
    o replaced header path to wish from "wish8.0" to "wish" to accomodate
      any possible version of Tk (in the ideal world, it should do some
      version checking, because vTcl is not compatible with versions prior
      to 8.0)
    o syntax coloring is done when user moves the cursor inside the
      current line or types a few typical keys (eg. [] {}, etc.)
    o fixed "Save Compound..." bug
	o dump widget aliases inside window procedure in preparation for
      multiple file support

          if options are about scrolling then window path is replaced by
          $base... id. the path is now relative to the parent window instead of
          beeing absolute
        o Centered preferences dialog
        o Support for combobox package (combobox by Bryan Oakley)
        o Font manager/Image manager now use default background/foreground
