如何更改kivy中的弹出颜色
How to change popup color in kivy
在Kivy中,Popup显示为灰色,需要修改什么使其变成红色
我的弹窗代码:
class MyPopup(Popup):
def show_popup(self):
content = BoxLayout(orientation="vertical")
content.add_widget(Label(text="Game Over", font_size=20))
mybutton_cancel = Button(text="Cancel", size_hint_y=None)
content.add_widget(mybutton_cancel)
mypopup = Popup(content = content,
title = "oops",
auto_dismiss = False,
size_hint = (.5, .5))
mybutton_cancel.bind(on_release=mypopup.dismiss)
mypopup.open()
我希望很明显,我说的是弹出窗口颜色,而不是弹出窗口后面的背景屏幕颜色或弹出文本颜色。我说的是弹出矩形的颜色。请指教
Popup
因为 ModalView
的 child 有一个 StringProperty
称为 background
,它指向来自 atlas 的图像。默认值为 atlas://data/images/defaulttheme/modalview-background
。在这里,我将其更改为默认按钮图像之一:
from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.popup import Popup
from kivy.uix.label import Label
class TestApp(App):
def build(self):
return Button(text="show", on_press=self.anim_btn)
def anim_btn(self, *args):
popup = Popup(title='Test popup',
content=Label(text='Hello world'),
size_hint=(None, None),
size=(400, 400),
background = 'atlas://data/images/defaulttheme/button_pressed'
).open()
if __name__ == "__main__":
TestApp().run()
此默认主题位于此处:https://github.com/kivy/kivy/blob/master/kivy/data/images/defaulttheme-0.png In order to customize your popup (and also, for example, buttons) you can create your own atlas (http://kivy.org/docs/api-kivy.atlas.html)。
