Overview

The aim of this project is to enhance Vision with a support for multiple screens.

Eiffel Studio

  • I'll give you here a step for step instruction at how I got a vision2 project to work under windows

Download

MS Platform SDK Microsoft .NET Framework Version 2.0 Redistributable Package (x86) .NET 2.0 SDK for x86

How I chose the Directories (just change everywhere I use them adequatly) =

  • C:\Eiffel57\ - Eiffel instal directory
  • C:\Eiffel57\soft-arch\ - svn checkout
  • C:\Program Files\Microsoft.NET\ - Microsoft.NET Framework
  • C:\Program Files\Microsoft Platform SDK\ - Microsoft Platform SDK
  • C:\cygwin\ - Cygwin Installation

needed SVN checkout

Install Gobo

DOS 

cd %EIFFEL_SRC%\library
tar xvfz %EIFFEL_SRC%\free_add_ons\gobo\gobo_34_win.tgz

Bash 

cd $EIFFEL_SRC/library
tar xvzf $EIFFEL_SRC/free_add_ons/gobo/gobo_34_win.tgz

set Environment Variables

set PATH=C:\Programme\Microsoft.NET\SDK\v2.0\Bin;C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727;C:\Programme\Microsoft Platform SDK\bin;C:\Programme\Microsoft Visual Studio 8\VC\bin;C:\Programme\Microsoft Visual Studio 8\Common7\IDE;C:\Programme\Microsoft Visual Studio 8\VC\vcpackages;C:\Programme\Microsoft Platform SDK\Bin;C:\Programme\Microsoft Visual Studio 8\VC\bin;%PATH%;C:\cygwin\bin

set INCLUDE=C:\Programme\Microsoft.NET\SDK\v2.0\include;C:\Programme\Microsoft Platform SDK\Include;C:\Programme\Microsoft Platform SDK\Include\crt;C:\Programme\Microsoft Platform SDK\Include\crt\sys;C:\Programme\Microsoft Platform SDK\Include\mfc;C:\Programme\Microsoft Platform SDK\Include\atl;C:\Programme\Microsoft Visual Studio 8\VC\include

set LIB=C:\Programme\Microsoft.NET\SDK\v2.0\Lib;C:\Programme\Microsoft Platform SDK\Lib;C:\Programme\Microsoft Visual Studio 8\VC\lib;

set ISE_EIFFEL=C:\Eiffel57\

These last Variables I'm not sure are needed...

set EIFFEL_SRC=C:\Eiffel57\soft-arch\

set ISE_PLATFORM=windows

set ISE_C_COMPILER=msc

Resources

  • In order to be able to change the library code you have to delete the 'readonly="True"' in the library tags of the project's acex file


  • Gdk - Resources:
    • class GdkDisplay
    • class GdkScreen


  • WEL - Resources:
    • NONE


  • Win32 API - Resources:
    • look at the platform SDK under 'Win32 API'
    • Wel uses a loopback function to get access to all fonts (it's pretty much the same that we have to do)
      • in the SDK you find the EnumFontFamilies function under 'Graphics Device Interface' -> 'Fonts and Text' -> '... Reference' -> '... Functions'
      • look at %Eiffel%\library\wel\clib\enumfold.c
      • look at class wel_font_family_enumerator - especially at feature cwin_enum_font_families


Implementation

class EV_SCREEN:

  • allscreenslist [EV_MULTISCREEN]
  • primaryscreen : EV_MULTISCREEN

class EV_MULTISCREEN (inherits EV_SCREEN):

  • create class
  • redefine inherited features for mutliscreen as needed

class EV_SCREEN_IMP (inherits EV_SCREEN_I):

  • add multiscreen features as needed

class EV_SCREEN_I:

  • add new deferred features from EV_SCREEN_IMP

class GDK_EXTERNALS:

  • add multiscreen features as needed

Milestones

M1: June 1st

  • needed gdk features
  • decide upon implementation

M2: May ???

  • To be completed by the team

To do

  • Fabio:
    • find needed WEL features (and underlying routines - WIN32 API)
    • create svn-dir (done. see resources)
    • look at Win32API and get dummy prog to work (see resources)


  • Pascal:
    • look at Win32API and get dummy prog to work (see resources)


  • Pawi
    • find out how to do the docu


  • Dario
    • find out how works 'external' (done. works under linux)
    • create Class EV_MULTISCREEN (inherits EV_SCREEN)
    • look at Win32API and get dummy prog to work (see resources)
