How can i make button from one button make function from other class in Kivy?-CodePudding

I'm trying to make that if i click tab button the content of this tab will change. In this specific example, I want to change TextInput to day that it is today. But I have no clue how to execute function from WoPlan class in Menu class. Or just how to influence the WoPlan textinput via menu's button from tab.

.kv

<Menu>:
    TabbedPanel:
        do_default_tab: False
        ORM:
            font_size: 30
            text: "ORM"

        WoPlan:
            font_size:30
            text: "WOP"
            on_press: root.WoPlan().weekday()

<WoPlan>:
    BoxLayout:
        orientation: "vertical"
        TextInput:
            id: weekday
            disabled: True

.py

class WoPlan(TabbedPanelItem):

    def weekday(self):
            curr_date = date.today()
            weekday = calendar.day_name[curr_date.weekday()]
            self.ids.weekday.text = weekday

class Menu(Screen):
    pass

CodePudding user response：

Instead of root.WoPlan().weekday(), you can write self.weekday(). The "self" refers to the Widget, in which the on_press is called ("WoPlan" in this case).

If you want to call the function from any other widget within the "Menu" Screen, e.g.:

<Menu>:
    TabbedPanel:
        do_default_tab: False
        ORM:
            font_size: 30
            text: "ORM"
        Button: #example widget
            on_release: root.ids["woplan"].weekday()

        WoPlan:
            id: woplan
            font_size:30
            text: "WOP"

I found out I can do that with current_tab: self.weekday()

I just needed to put it in here

<Menu>:
    TabbedPanel:
        do_default_tab: False
        ORM:
            font_size: 30
            text: "ORM"

        WoPlan:
            font_size: 30
            text: "WOP"
            current_tab: self.weekday()
