* ext/tk/*: full update Ruby/Tk to support Ruby(1.9|1.8) and Tc/Tk8.5. * ext/tk/lib/tkextlib/tile.rb: [incompatible] remove TileWidgets' instate/state/identify method to avoid the conflict with standard widget options. Those methods are renamed to ttk_instate/ttk_state/ ttk_identify (tile_instate/tile_state/tile_identify are available too). Although I don't recommend, if you realy need old methods, please define "Tk::USE_OBSOLETE_TILE_STATE_METHOD = true" before "require 'tkextlib/tile'". * ext/tk/lib/tkextlib/tile.rb: "Tk::Tile::__Import_Tile_Widgets__!" is obsolete. It outputs warning. To control default widget set, use "Tk.default_widget_set = :Ttk". * ext/tk/lib/tk.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__ method and __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method are defind as module methods of TkConfigMethod. It may help users to wrap old Ruby/Tk scripts (use standard widgets) to force to use Ttk widgets. Ttk widgets don't have some options of standard widgets which are control the view of widgets. When set ignore-mode true, configure method tries to ignoure such unknown options with no exception. Of course, it may raise other troubles on the GUI design. So, those are a little danger methods. * ext/tk/lib/tk/itemconfig.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__ method and __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method are defind as module methods of TkItemConfigMethod as the same purpose as TkConfigMethod's ones. * ext/tk/sample/ttk_wrapper.rb: A new example. This is a tool for wrapping old Ruby/Tk scripts (which use standard widgets) to use Ttk (Tile) widgets as default. * ext/tk/sample/tkextlib/tile/demo.rb: use ttk_instate/ttk_state method instead of instate/state method. * ext/tk/lib/tk/root, ext/tk/lib/tk/namespace.rb, ext/tk/lib/tk/text.rb, ext/tk/lib/tkextlib/*: some 'instance_eval's are replaced to "instance_exec(self)". * ext/tk/lib/tk/event.rb: bug fix on KEY_TBL and PROC_TBL (?x is not a character code on Ruby1.9). * ext/tk/lib/tk/variable.rb: support new style of operation argument on Tcl/Tk's 'trace' command for variables. * ext/tk/sample/demos-jp/widget, ext/tk/sample/demos-en/widget: bug fix * ext/tk/sammple/demos-jp/textpeer.rb, ext/tk/sammple/demos-en/textpeer.rb: new widget demo. * ext/tk/tcltklib.c: decrase SEGV troubles (probably) * ext/tk/lib/tk.rb: remove Thread.critical access if Ruby1.9 * ext/tk/lib/tk/multi-tk.rb: support Ruby1.9 (probably) * ext/tk/lib/tkextlib/tile.rb: add method to define Tcl/Tk command to make Tcl/Tk theme sources (based on different version of Tile extension) available. (Tk::Tile::__define_LoadImages_proc_for_comaptibility__) * ext/tk/lib/tk.rb, ext/tk/lib/tk/wm.rb: support dockable frames (Tcl/Tk8.5 feature). 'wm' command can treat many kinds of widgets as toplevel widgets. * ext/tk/lib/tkextlib/tile/style.rb: ditto. (Tk::Tile::Style.__define_wrapper_proc_for_compatibility__) * ext/tk/lib/tk/font.rb: add actual_hash and metrics_hash to get properties as a hash. metrics_hash method returns a boolean value for 'fixed' option. But metrics method returns numeric value (0 or 1) for 'fixed' option, because of backward compatibility. * ext/tk/lib/tk/timer.rb: somtimes fail to set callback procedure. * ext/tk/lib/tk.rb: add Tk.sleep and Tk.wakeup method. Tk.sleep doesn't block the eventloop. It will be better to use the method in event callbacks. * ext/tk/sample/tksleep_sample.rb: sample script about Tk.sleep. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@15848 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
