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

=Eiffel Studio=
[http://eiffelsoftware.origo.ethz.ch/index.php/Multi_screen_support_build_install 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 or just click on the project settings in the Eiffel Studio and change it there.

*[http://msdn2.microsoft.com/en-us/library/system.windows.forms.screen_members.aspx 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 callback function to get access to all fonts (it's pretty much the same that we have to do)
*** see the [http://origo.ethz.ch/pipermail/es-ui/2006-June/000016.html 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_MONITOR]
* primaryscreen : EV_MONITOR

class EV_MONITOR:
* create class
* width, height, vertical_resolution, horzintal_resolution
* monitor_at_position (pos: EV_COORDINATE): INTEGER
* get_global_coordinate (pos: EV_COORDINATE; screen_nr: INTEGER): EV_COORDINATE

class EV_MONITOR_IMP :
* add multiscreen features as needed
* Windows: is client of WEL_MONITORS_DC

class EV_MONITOR_I:
* add new deferred features from EV_MONITOR_IMP

class GDK_EXTERNALS:
* add multiscreen features as needed

=== Wel ===

class WEL_MONITOR_ENUMERATOR:
* deferred feature action
* accesses C functions to enumerate all monitors

class WEL_MONITORS_DC (inherits: WEL_MONITOR_ENUMERATOR):
* defines deferred feature action from WEL_MONITOR_ENUMERATOR
* gives acces to the DC of all monitors

=Milestones=

==M1: June 1st==

* needed gdk features
* decide upon implementation

==M2: May ??? ==
* To be completed by the team

=To do=
*Fabio:
**create svn-dir -> 100%
**install EiffelStudio 5.7 and get dummy prog to work (see resources) -> 80%
**look at Win32API -> 0%
**find needed WEL features (and underlying routines - WIN32 API) -> 0%

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

*Pawi
**find out how to do the docu (take a look at [http://eiffelsoftware.origo.ethz.ch/index.php/Downloads Doc builder])

*Dario
**find out how works 'external' (done.)
**create Class EV_MONITOR(inherits EV_SCREEN) (done; see svn)
**implement linux version of EV_MONITOR_IMP (done.)
