I'm trying to build a kivy app using some custom widgets. However whenever I try to use them they never work with my layout. Using a normal button:
import kivy
kivy.require('1.8.0')
from kivy.app import App
from kivy.uix.widget import Widget
from kivy.properties import ListProperty
class RootWidget(Widget):pass
class myApp(App):
def build(self):
global rw
rw = RootWidget()
return rw
if __name__ == '__main__':
myApp().run()
#:kivy 1.8.0
<RootWidget>:
BoxLayout:
size: root.size
orientation: 'horizontal'
spacing: 10
padding: 10
Button:
id: abut
text: "Custom Button"
This works as expected, my Button basically takes up the entire window. However when I try replacing the Button with my custom button
import kivy
kivy.require('1.8.0')
from kivy.app import App
from kivy.uix.widget import Widget
from kivy.properties import ListProperty
class MyWidget(Widget):
pressed = ListProperty([0, 0])
def on_touch_down(self, touch):
if self.collide_point(*touch.pos):
self.pressed = touch.pos
return True
return super(MyWidget, self).on_touch_down(touch)
def on_pressed(self, instance, pos):
print ('pressed at {pos}'.format(pos=pos))
class RootWidget(Widget):pass
class someApp(App):
def build(self):
global rw
rw = RootWidget()
return rw
if __name__ == '__main__':
someApp().run()
#:kivy 1.8.0
<MyWidget>:
BoxLayout:
orientation: 'horizontal'
spacing: 10
Button:
id: abut
text: "Custom Button"
<RootWidget>:
BoxLayout:
size: root.size
orientation: 'horizontal'
spacing: 10
padding: 10
MyWidget:
it only appears in the bottom left-hand corner of the window and doesn't behave like a button. What am I missing?
Furthermore, is it even necessary to create a custom button this way? The kivy tutorials used this sort of method to make their custom button but can't I just do something like this
Button:
on_press: root.do_action()
to make each button behave differently?
