Python Kivy Listview: How To Delete Selected Listitembutton?

I'm trying to learn kivy by building a simple todo-list app like suggested by Dusty Phillips, author of the book 'Creating apps in Kivy'. This is the code so far: from kivy.app imp

Solution 1:

After a lot of reading ListView API docs & examples, I finally found out myself. What we need is the selection-Property of the listadapter-Class, then we can simply call the inherited remove method of the adapter.data-ListProperty.

So for anyone interesested this is the code:

defdel_task(self, *args):
    ifself.task_list.adapter.selection:
        selection = self.task_list.adapter.selection[0].text
        self.task_list.adapter.data.remove(selection)
        self.task_list._trigger_reset_populate()
