我看着this的問題,但那是不同的。kivy:如何在BoxLayout中放置圖像?
我剛開始用kivy,所以我想這是很簡單的東西:\
我想兩個圖像放置到的BoxLayout。這是我到目前爲止的代碼:
import kivy
kivy.require('1.9.1')
from kivy.app import App
from kivy.core.image import Image as CoreImage
from kivy.uix.boxlayout import BoxLayout
class TestApp(App):
def build(self):
layout = BoxLayout(orientation='horizontal')
im1 = CoreImage("image1.png")
im2 = CoreImage("image2.png")
layout.add_widget(im1) # this is line 33
layout.add_widget(im2)
return layout
if __name__ == '__main__':
TestApp().run()
程序不顯示一個窗口,但打印此錯誤信息到終端:
Traceback (most recent call last):
File "./myprog.py", line 39, in <module>
TestApp().run()
File "/usr/lib/python3.6/site-packages/kivy/app.py", line 802, in run
root = self.build()
File "./myprog.py", line 33, in build
layout.add_widget(im1)
File "/usr/lib/python3.6/site-packages/kivy/uix/boxlayout.py", line 212, in add_widget
pos_hint=self._trigger_layout)
File "kivy/_event.pyx", line 438, in kivy._event.EventDispatcher.bind (kivy/_event.c:6473)
KeyError: 'pos_hint'
存在的圖像。如果我將pos_hint={'x':0,'y':0}
添加到CoreImage「構造函數」中,我會得到相同的錯誤。
我正在使用python 3.6.0和kivy 1.9.1
