class WebContent:
|
|
"""Stores all dynamically modified content that a particular web view
|

will be populated with.
|
|
|
|
Attributes:
|
|
body {str} -- HTML body
|
|
head {str} -- HTML head
|
|
css {List[str]} -- List of media server subpaths,
|
|
each pointing to a CSS file
|
|
js {List[str]} -- List of media server subpaths,
|
|
each pointing to a JS file
|
|
|
|
Important Notes:
|
|
- When modifying the attributes specified above, please make sure your
|
|
changes only perform the minimum requried edits to make your add-on work.
|
|
You should avoid overwriting or interfering with existing data as much
|
|
as possible, instead opting to append your own changes, e.g.:
|
|
|
|
def on_webview_will_set_content(web_content: WebContent, context):
|
|
web_content.body += "<my_html>"
|
|
web_content.head += "<my_head>"
|
|
|
|
- The paths specified in `css` and `js` need to be accessible by Anki's
|
|
media server. All list members without a specified subpath are assumed
|
|
to be located under `/_anki`, which is the media server subpath used
|
|
for all web assets shipped with Anki.
|
|
|
|
Add-ons may expose their own web assets by utilizing
|
|
aqt.addons.AddonManager.setWebExports(). Web exports registered
|
|
in this manner may then be accessed under the `/_addons` subpath.
|
|
|
|
E.g., to allow access to a `my-addon.js` and `my-addon.css` residing
|
|
in a "web" subfolder in your add-on package, first register the
|
|
corresponding web export:
|
|
|
|
> from aqt import mw
|
|
> mw.addonManager.setWebExports(__name__, r"web/.*(css|js)")
|
|
|
|
Then append the subpaths to the corresponding web_content fields
|
|
within a function subscribing to gui_hooks.webview_will_set_content:
|
|
|
|
def on_webview_will_set_content(web_content: WebContent, context):
|
|
addon_package = mw.addonManager.addonFromModule(__name__)
|
|
web_content.css.append(
|
|
f"/_addons/{addon_package}/web/my-addon.css")
|
|
web_content.js.append(
|
|
f"/_addons/{addon_package}/web/my-addon.js")
|
|
|
|
Note that '/' will also match the os specific path separator.
