Overview
The aim of this project is to enhance Vision with a support for multiple screens.
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.
- 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 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://svn.eiffel.com/eiffelstudio/branches/eth/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:
- 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.)
- create Class EV_MONITOR(inherits EV_SCREEN) (done; see svn)
- implement linux version of EV_MONITOR_IMP (done.)
