在更改时显示kivy滑块值 [英] Display kivy slider value as it changes

问题描述

我想知道是否可以将kivy微调器值显示为移动标签，以便用户确切知道滑块的当前值是什么.

I was wondering whether it was possible to displays kivy spinner values as a moving label, so that the user knows exactly what the current value of the slider is.

谢谢

推荐答案

您只需将侦听器绑定到值更改事件

you just bind a listener to the value change event

some_label = Label(...)
my_slider = Slider(...)
def OnSliderValueChange(instance,value):
    some_label.text = str(value)

my_slider.bind(value=OnSliderValueChange)

在.kv文件中，正如所指出的那样，您可以执行类似的操作

as inclement points out in the .kv file you could do something like

<PongGame>:
    ...
    canvas:
        Rectangle:
            ...
    Label:
        ...
        text: str(slider_id.value)
     Slider:
        ...
        id: slider_id
