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 (see also the following mails)
- 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
Vision2
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
Wel

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)
