SelectedItems in Ebook Editor

[luckylittle]

I am developing a renaming plugin that will do similar thing as request_change_ext function in the FileList class (https://github.com/kovidgoyal/calibr...k/file_list.py).


However, i don't seem to understand where is .selectedItems() coming from in request_rename_common?

Can someone led some light on it, please?

I looked into it closer now, is this the correct statement?

* self.build creates a container of names, categories, icons (https://github.com/kovidgoyal/calibr...e_list.py#L321)

* the above leverages function get_state to get the array of selected items (https://github.com/kovidgoyal/calibr...e_list.py#L255)

[kovidgoyal]

selectedItems() is a Qt method from the QTreeWidget class. self.build() populates the QTreeWidget. IIRC it only uses get_state() if the state before the build is to be preserved (i.e. the selected files and expanded nodes).

Ok, i am able to get it working for one file at the time - getting the selected name with

self.gui.file_list.current_name

But what about bulk select?

Also, my plugin is ONLY visible in menu and not on the toolbar (although allowed_in_toolbar=True and for_toolbar=True), do you know what could be the reason?

[kovidgoyal]

Use selected_names

And are you saying you cannot add your plugin to the toolbar? Look at the demo plugin or one of the other plugins to check what the difference is.

I fixed the toolbar, but selected_names doesn't exist:

AttributeError: 'FileListWidget' object has no attribute 'selected_names'

The whole function:

def request_remove_ext(self):
# Import calibre/src/calibre/gui2/tweak_book/file_list.py
from calibre.gui2.tweak_book.file_list import FileList
self.boss.add_savepoint('Before: File Extension Remover')
names = self.gui.file_list.selected_names
if names is not None:
def change_name(name):
base = posixpath.splitext(name)[0]
return base
name_map = {n:change_name(n) for n in names}
self.boss.bulk_rename_requested.emit(name_map)

---
To add, this works, but with only one selected file:

def request_remove_ext(self):
# Import calibre/src/calibre/gui2/tweak_book/file_list.py
from calibre.gui2.tweak_book.file_list import FileList
self.boss.add_savepoint('Before: File Extension Remover')
name = self.gui.file_list.current_name
name_without_ext = posixpath.splitext(name)[0]
self.boss.rename_requested(name,name_without_ext)

file_list.file_list.selected_names

Thanks, this was very helpful.
