Deleting book

[filipexim]

Hi, I'm doing my first contribution to an open source community, and I choose calibre to start. I'm looking for something simple to begin. I noticed that when you delete a book its cover doesn't disappear from the right side bar. I want to change this behavior and automatically select the next book on list to have it's cover shown on this bar.

I'm looking at the calibre/gui2/actions/delete.py file. I have some questions:

1 - Where can I see the available methods and variables for self.gui? I understood that this is used to access the gui elements, but i couldn't find what it's available to be used.

2 - To do what I'm pretending to do, where else in the code should I be also looking?

Thanks.

If you want to see what methods are available on any python object just insert a

print (vars(obj))

and run calibre with

calibre-debug -g

The self.gui class is defined in gui2/ui.py

Also in the delete.py file:

I can't find the methods for library_view variable in

self.gui.library_view

Already tried:

print (vars(self.gui.library_view))

I'm guessing this is something from QT library.

Great!
It's working. Just one more thing:
When you delete all books from calibre, the cover of the last selected book still appears on the right side bar. How can I set this image to switch to the "default_cover" instead?
