python - How can I change the orientation of a buttons in a stack layout in Kivy -

- 

from kivy.app import app kivy.uix.button import button kivy.uix.stacklayout import stacklayout   class mylayout(stacklayout):     def __init__(self, **kwargs):         super(mylayout, self).__init__(**kwargs)         in range(10):             btn = button(text=str(i), width=40, size_hint=(none, 0.15), orientation= 'lr-bt')             self.add_widget(btn)   class nameapp(app):     def build(self):         ml = mylayout()         return ml  if __name__ == "__main__":     nameapp().run()

i have attempted change orientation here, orientation displayed on app still if default

orientation property of layout, not of widgets contains. can use

self.orientation = "lr-bt"

in __init__ function assign property layout. assign in appropriate .kv file if use that.

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
