[英]KIVY: how to have same set of widgets on multiple screens
我想在所有屏幕上添加相同類型的小部件。 單擊其中任何一個添加的小部件時,將從所有屏幕中刪除該小部件。 這是當前的方法
def drinksSelect(self,value): # creating a button by referring the id of the layout in which to create button
drinkImagePath = {'pepsi': 'drinksPictures/pepsi.png','7up': 'drinksPictures/7up.png'}
if self.root.a_s.l < self.root.a_s.limit: # You know what I mean
st = 'number'
img = myImage(source= drinkImagePath[value], size=(200,20), id=st)
img2 = myImage(source=drinkImagePath[value], size=(200, 20), id='soo')
self.root.a_s.ids.place_remaining.add_widget(img)
self.root.m_s.ids.place.add_widget(img2)
self.root.a_s.l += 1
我正在使用此刪除圖像
class myImage (Image):
def on_touch_down(self, touch):
if self.collide_point(*touch.pos):
self.parent.remove_widget(self)
這樣做的問題在於,它僅刪除單擊的圖像,而不刪除其他屏幕上的圖像。
嘗試這個:
def drinksSelect(self, value): # creating a button by referring the id of the layout in which to create button
drinkImagePath = {'pepsi': 'drinksPictures/pepsi.png', '7up': 'drinksPictures/7up.png'}
if self.root.a_s.l < self.root.a_s.limit: # You know what I mean
st = 'number'
img = myImage(source=drinkImagePath[value], size=(200, 20), id=st)
img2 = myImage(source=drinkImagePath[value], size=(200, 20), id='soo')
img.twin = img2
img2.twin = img
button.a_s = self.root.a_s
button2.a_s = self.root.a_s
self.root.a_s.ids.place_remaining.add_widget(img)
self.root.m_s.ids.place.add_widget(img2)
self.root.a_s.l += 1
class myImage(Image):
twin = ObjectProperty()
a_s = ObjectProperty()
def on_touch_down(self, touch):
if self.collide_point(*touch.pos):
self.parent.remove_widget(self)
self.twin.parent.remove_widget(self.twin)
self.a_s.l -= 1
