Partial class
Bases: _Page
Reusable Page content.
Partials are used when you need to use a partial page content in different and not related pages. This allows not to have to repeat yourself when creating your page templates.
Visual elements such as part,
dialog or
pane can use Partials.
Note that Partial has no constructor (no __init__() method): to create a
Partial, you must call the Gui.add_partial() function.
Partials can be really handy if you want to modify a section of a page:
the update_content() method dynamically update pages that make use
of this Partial therefore making it easy to change the content of
any page, at any moment.
