Subject: Current wxRuby status

Hi, All

Do you know I'm working on wxRuby at http://sourceforge.jp/projects/wxruby ?
You can download the beta version 0.01.
Sorry for no documents,many missing classes and methods.

Tested on

    Windows XP
    wxMSW 2.4.0
    ruby 1.8.0 preview2
    Visual C++ 6.0

    RedHat Linux 8.0
    wxGTK 2.4.0
    ruby 1.8.0 preview2
    gcc 3.2

Here is sample code.

=begin CODE

    require 'wx'
    include Wx

    Minimal_Quit = 1
    Minimal_About = WxID_ABOUT

    def labeledEntry(parent,sizer,label,default)
      sizer.Add(WxStaticText.new(parent,-1,label.to_s,
WxDefaultPosition,WxDefaultSize,WxALIGN_RIGHT),1,WxALIGN_CENTER_VERTICAL)
      sizer.Add(r=WxTextCtrl.new(parent,-1,default.to_s,
WxDefaultPosition,WxDefaultSize,WxALIGN_LEFT),1,WxALIGN_CENTER_VERTICAL)
      return r
    end

    class MyFrame < WxFrame
      def initialize(title,pos,size,style=WxDEFAULT_FRAME_STYLE)
        super(nil,-1,title,pos,size,style)

        if WxRUBY_PLATFORM == "WXMSW"
          SetIcon(WxIcon.new("mondrian.ico",WxBITMAP_TYPE_ICO))
        else
          SetIcon(WxIcon.new("mondrian.xpm",WxBITMAP_TYPE_XPM))
        end

        menuFile = WxMenu.new
        helpMenu = WxMenu.new
        helpMenu.Append(Minimal_About, "&About...\tF1", "Show about dialog")
        menuFile.Append(Minimal_Quit, "E&xit\tAlt-X", "Quit this program")
        menuBar = WxMenuBar.new
        menuBar.Append(menuFile, "&File")
        menuBar.Append(helpMenu, "&Help")
        SetMenuBar(menuBar)

        CreateStatusBar(2)
        SetStatusText("Welcome to wxRuby!")

        EVT_MENU(self, Minimal_Quit,  "OnQuit")
        EVT_MENU(self, Minimal_About,  "OnAbout")
      end

      def OnQuit(event)
        Close(TRUE)
      end

      def OnAbout(event)
        msg =  sprintf("This is the About dialog of the minimal sample.\n" \
             "Welcome to %s", WxVERSION_STRING)

        WxMessageBox(msg, "About Minimal", WxOK | WxICON_INFORMATION, self)
      end
    end

    class WxRbApp < WxApp
      def OnInit
        frame = MyFrame.new("Minimal wxRuby App",WxPoint.new(50, 50),
WxSize.new(450, 340))
        frame.Show(TRUE)
      end
    end

    a = WxRbApp.new
    a.MainLoop()

=end CODE

I have some issues about current version.

1. Library name should be renamed?
    require 'wx' ==> require 'wxRuby' or else.

2. Constant name should be renamed?
    WxOK      ==> OK      or
    Wx::WxOK  ==> Wx::OK

3. Event handler method name convention
    EVT_MENU(self,Minimal_Quit,"OnQuit") ==>
EVT_MENU(self,Minimal_Quit,:OnQuit) or else.

4. Ruby thread support routine
    I used OnIdle event handler like this.

    void wxRbApp::OnIdle(wxIdleEvent& event)
    {
        struct timeval wait;

        wait.tv_sec  = 0;
        wait.tv_usec = 100000; /* 100ms */

        CHECK_INTS;
        if (!rb_thread_critical) rb_thread_wait_for(wait);

        wxApp::OnIdle(event);
    }

    Is it the best way or is there some other way?

5. building C++ extention library without SWIG or other automated tools.
    It needs more time and more coding, but the source code is easy to
understand.

What do you think about the above issues?

I wish someone inspect my source code and correct bugs and problems.
