Overview

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

Eiffel Studio

Step by Step build installation

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

• C# screen class interface

• 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)
    • see the mail from manu
    • 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

• Team SVN Rep: You need to backup and remove the directories 'vison2' and 'wel' in your '/Eiffel57/library/' directory and run a svn checkout from https://eiffelsoftware.origo.ethz.ch/svn/es/branches/soft-arch/TeamMultiScreenSupport .

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
• monitor_at_position (pos: EV_COORDINATE): INTEGER
• get_global_coordinate (pos: EV_COORDINATE, screen_nr: INTEGER): EV_COORDINATE

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 (take a look at Doc builder)

• 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)
