Re: How nautilus places item on desktop window?

[leena chourey <leenagour gmail com>]

Dear sir,

I have started with nautilus-main.c and nautilus-application.c to understand the nautilus code (2.30.1). Findings are as follows:

• In application.c , function unique_app_send_message(application->unique_app,COMMAND_START_DESKTOP, NULL); is responsible to draw Desktop and its contents.
• Similarly in the same file, function unique_app_send_message(application->unique_app, UNIQUE_OPEN, message); is responsible to open home folder.

As you suggested in the last mail, nautilus-icon-container.c has all icon related details, but doubts/queries:

• How src/ and libnautilus-private/nautilus-icon-container.c are related. I tried to display/debug using printf() in  nautilus-icon-container.c, but control does not reach there, no print results?
  
• I want to checkout the methodology to place icons on desktop using grid? Why focus does not goto the first item of next column on down arrow key?
• How icons have no standard size to display and how icons are placed in  uneven manner. Uneven means, according to the size of icon the row decides?
• By which way control selects to move focus on next element of same row?
  

Please guide in the same reference.

With regards
Leena

No, unfortunately there's no such documentation available, except for
the source code itself. As I told you in a previous mail, you will have
to explore code in the NautilusIconContainer class to get a sense of
what's happening.

Thanks,
