Function for Close Tab

Navigation_Tabs.kv

Use on_ref_press method

  1.     MDTabs:
  2.         id: tabs
  3.         text: "1"
  4. +       on_ref_press: app.on_ref_press(*args)
  1. class MainApp(MDApp):
  2. +    def on_ref_press(

  7. +        instance_tab_bar,
  8. +        instance_carousel,
  9. +    ):
  10. +        '''
  11. +        The method will be called when the ``on_ref_press`` event
  12. +        occurs when you, for example, use markup text for tabs.
  13. +        :param instance_tabs: <kivymd.uix.tab.MDTabs object>
  14. +        :param instance_tab_label: <kivymd.uix.tab.MDTabsLabel object>

  17. +        :param instance_carousel: <kivymd.uix.tab.MDTabsCarousel object>
  18. +        '''
  19. +
  20. +        # Removes a tab by clicking on the close icon on the left.
  21. +        for instance_tab in instance_carousel.slides:
  22. +            if instance_tab.text == instance_tab_label.text:
  23. +                instance_tabs.remove_widget(instance_tab_label)
