如何将 .py 文件中的按钮动态添加到 .kv 文件中屏幕管理器的单个屏幕

Question

如何将按钮动态添加到 .kv 文件的屏幕管理器的特定屏幕？问题是，创建的按钮显示在所有屏幕上。

我有一个正在开发的程序，它允许用户在那里输入特定条件并计算 ACFM。我目前正在尝试设置一个允许用户创建多个文件的文件屏幕。我试图允许一个名为“创建新文件”的主按钮在第一个屏幕上创建更多按钮。问题是，创建的按钮显示在所有屏幕上。

主文件

from kivy.app import App

from kivy.lang import Builder

from kivy.core.window import Window

from kivy.uix.floatlayout import FloatLayout

import Functions as f1

from kivy.uix.button import Button

Window.size = (300,625)

window_x = Window.width

window_y = Window.height

Builder.load_file("main.kv")

class counter:

    def __init__(self):

        self.count = 2

    def increase(self):

        self.count += 1

b = counter()

class Calc(FloatLayout):

    def testbutton(self,instance):

        btn = Button(text = "testing123", color = (1,1,1,1),

                     size_hint =(.5,.05),

                     pos = (0,(window_y-(window_y*(.07+(b.count*.05)))))

                     )

        b.increase()

        self.add_widget(btn)

    # define the multiplication of a function

    def calculate(self, instance):

        f = float(self.flow.text)

        p = float(self.pressure.text)

        t = float(self.temperature.text)

        sg = float(self.specific_gravity.text)

        self.acfm.text = str(f) #str(f1.ACFM(f,p,t,sg)) I commented this out for the purpose of posting this in my questions.

class test(App):

    def build(self):

        return Calc()

if __name__=="__main__":

    test().run()

我没有收到任何错误消息。我只希望 .py 文件中动态创建的按钮只能转到 .kv 文件的一个屏幕。

Answer 1

您当前正在将其添加到作为根的 Calc FloatLayout 中，并且每个屏幕都是该根的子项。如果您只想将其添加到一个屏幕，则需要调用该特定屏幕的 add_widgets 函数。一种选择是通过 id像下面这样更改kv文件&nbsp; &nbsp; &nbsp; &nbsp; Screen:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; id: id_solverscreen&nbsp;
