[Scummvm-devel] [PATCH] let the user sort it's configured games

[Gregor Jasny]

Hi,

this patch lets the user sort it's games diplayed in the menu. The changes 
are:
* Change domain names to 6 digit long strings.
* Store the gameid in the gameid key

This have several advantages:
* No more domain name collisions if a gameid is already there.
* Good base for sorting ;)

TODO:
* Collect some feedback!
* Find a position for the Up/Down buttons
* Add a combobox for all gameids in edit widget
* Review other backends

The patch is divided in two seperate ones:

1. scumm-menu-core patch:
map:
* added int size() function

config-manager:
* check that domains can only consists of [A-Za-z0-9]
* getInt() check for conversion error
* added swapDomains(dom1, dom2): swap the contents of this two domain (needed 
for up/down)
* added int numGameDomains(): return the number of known game Domains

ListWidget:
* added setSelection(int item): NEEDS REVIEW!

2. scumm-menu-updown patch:
gamedetector:
* print out as "Target GameID Description" (e.g. 000001 atlantis Indy4)

launcher:
* move and rename old domain lineEdit field to "Game Id"
* add up/down Button
* add funtions for up/down
* store the last selection in [scummvm]->lastselectedgame and reselect on 
scummvm reload

Please give some feedback!

Cheers,
-Gregor
