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


  • 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


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

class EV_COORDINATE:

  • add multiscreen awarness

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)
