我正在做一个 kivy 项目......我正在使用从函数创建的切换按钮......我怎么知道选择了什么？

Question

here is the main python file...

class MainWindow(Screen): def Get_Trending(self): Twitz = Trending_on_Twitter() Tikz = Trending_on_TikTok() ingrams = Trending_on_Instagram()

    Trending = Twitz + Tikz
    num = 0

    for item in Trending:
        button = ToggleButton(text=Trending[num])
        self.ids.grid.add_widget(button)
        num+=1

here is my kivy file...

BoxLayout:

        size_hint_y: .8
        orientation:"vertical"
        
        ScrollView:
            GridLayout:
                id:grid
                orientation:"vertical"
                size_hint_y: None
                height: self.minimum_height
                row_default_height:60
                cols:1
                Label:
                    id: top_area
                    text:"Trending On SocialMedia"
                    height: self.texture_size[1]
        BoxLayout:
            size_hint_y:.1
            orientation:"horizontal"
            Button:
                text:'Select All'
            Button:
                text:"next"

everything is working fine when it comes to being able to see my buttons and being able to scroll thru them... i can click them... but i added two buttons... select all and next... i just dont understand how to get the states of these buttons and when i click select all to select all... and when i click next get it to add which buttons were selected to either a list or dictionary or anything really...

thankx in advance

num = 0 for item in Trending: mybutton = ToggleButton( text =Trending[num]) mybutton.bind(on_press = self.choices) self.ids.grid.add_widget(mybutton) num+=1

def choices(self,coo):
    global Hash_Tags_Selected
    #print(coo.text)
    #print(type(coo.text))
    if coo.text in Hash_Tags_Selected:
        try:
            Hash_Tags_Selected.remove(coo.text)
        except:
            pass
    else:
        try:
            Hash_Tags_Selected.append(coo.text)
        except:
            pass
    print(Hash_Tags_Selected)
