From 57a3925cc09f4d5fdc25f247d980f69e3aae33a3 Mon Sep 17 00:00:00 2001 From: nagai Date: Wed, 27 Feb 2008 18:44:31 +0000 Subject: * ext/tk/lib/tk.rb, ext/tk/lib/*: make default widget set switchable between Tk (standard Tcl/Tk widget set) and Ttk (Tile). Initial default widget set is Tk. Now, toplevel widget classes are removed and defined as aliases. For example, "TkButton" is an alias of the "Tk::Button" class. Those aliases are replaced when switching default widget set. "Tk.default_widget_set=" is the method for switching default widget set. "Tk.default_widget_set = :Ttk" defines Ttk (Tile) widget set as default. It means that "TkButton" denotes "Tk::Tile::Button" class. And then, "TkButton.new" creates a Tk::Tile::Button widget. Of course, you can back to use standard Tk widgets as the default widget set by calling "Tk.default_widget_set = :Tk", whenever you want. Based on thie feature, you can use Ttk widget styling engine on your old Ruby/Tk application without modifying its source, if you don'tuse widget options unsupported on Ttk widgets (At first, call "Tk.default_widget_set = :Ttk", and next load and run your application). This is one step for supporting Tcl/Tk8.5 features. git-svn-id: http://svn.ruby-lang.org/repos/ruby/trunk@15618 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- ext/tk/lib/tkextlib/tile/tscale.rb | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'ext/tk/lib/tkextlib/tile/tscale.rb') diff --git a/ext/tk/lib/tkextlib/tile/tscale.rb b/ext/tk/lib/tkextlib/tile/tscale.rb index 7ec72e351..2c46fd9bd 100644 --- a/ext/tk/lib/tkextlib/tile/tscale.rb +++ b/ext/tk/lib/tkextlib/tile/tscale.rb @@ -7,7 +7,7 @@ require 'tkextlib/tile.rb' module Tk module Tile - class TScale < TkScale + class TScale < Tk::Scale end Scale = TScale @@ -17,7 +17,10 @@ module Tk end end -class Tk::Tile::TScale < TkScale +Tk.__set_toplevel_aliases__(:Ttk, Tk::Tile::Scale, :TkScale) + + +class Tk::Tile::TScale < Tk::Scale include Tk::Tile::TileWidget if Tk::Tile::USE_TTK_NAMESPACE -- cgit
