[SOLVED] Problem with Kivy

Scripting Issues
1

Hello everyone, im trying to use kivy with @Cheaterman 's kivy integration
And add something to core/window.py to use TextInput (crashing without this);

class CWindow:
    def bind(self,**args):
        pass
    def unbind(self,**args):
        pass
def PatchWindow(v=True):
    if not v:kivy.core.window.Window=None
    else:kivy.core.window.Window=CWindow()
PatchWindow()

Im trying to make multiple screens like intro, login, character select etc… (classic rpg style)
but when i switch to another kivy app, it doesnt get keyboard inputs! Here some codes and video;

uiIntro.py;

import sys
from panda3d.core import *
from panda3d_kivy.app import App
import vui
import uiPhase

class IntroWindow(App):
	def movePhase(self,phase):
		if phase=='login':
			uiPhase.TARGET_PHASE=phase
			self.stop()
			return
	def FadeIn(self):
		if self.neuera_logo.opacity<1:
			self.neuera_logo.opacity+=.01
			return
		self.fade=1
	def FadeOut(self):
		if self.neuera_logo.opacity>0:
			self.neuera_logo.opacity-=.01
			return
		self.fade=2
	def Fade(self,task):
		if self.fade==2:
			self.movePhase('login')
			self.fade=3
			return task.done
		if self.fade==0:self.FadeIn()
		if self.fade==1:self.FadeOut()
		return task.cont
	def build(self):
		self.fade=0
		self.canvas=vui.CCanvas(size=(vui.SCREEN_W,vui.SCREEN_H),pos=(0,0))
		self.bg=vui.Image(parent=self.canvas, source='bin/neuera/ui/logo/black_screen.png', size=(vui.SCREEN_W,vui.SCREEN_H), fit_mode='cover')
		self.neuera_logo=vui.Image(parent=self.canvas, source='bin/neuera/ui/logo/neuera_logo.png', size=(vui.SCREEN_W,vui.SCREEN_H), fit_mode='cover')
		self.neuera_logo.opacity=0
		taskMgr.add(self.Fade, 'intro_fade')
		uiPhase.CUR_PHASE='intro'
		return self.canvas

		self.login_wnd = LoginWindow(self)
		self.login_wnd.run()

app = ValkeraApp()
app.run()

Any idea?
Kind Regards…

I think I’ve solved the problem. Instead of launching a new kivy app, it makes more sense to create the new screen by clearing the widgets;

LoginWindow;

class LoginWindow:
	def ExitGame(self):
		App.get_running_app().stop()
		sys.exit()
	def build(self):
		self.canvas=vui.CCanvas(size=(vui.SCREEN_W,vui.SCREEN_H),pos=(0,0))
		self.bg=vui.Image(parent=self.canvas, source='bin/neuera/ui/general/windows/login_bg_1.png', size=(vui.SCREEN_W,vui.SCREEN_H), fit_mode='cover')
		self.login_board=vui.Thinboard(parent=self.canvas, size=(256,200), pos=(vui.SCREEN_W*0.5-128,vui.SCREEN_H*0.5-80))
		self.user_lbl=vui.Label(parent=self.login_board, text='username:', pos=(30,self.login_board.size[1]-50), size_hint = (1, None))
		self.user_edit=vui.Edit(parent=self.login_board, text='testuser', multiline=False, size=(120,26), pos=(100,self.login_board.size[1]-60))
		self.pass_lbl=vui.Label(parent=self.login_board, text='password:', pos=(30,self.login_board.size[1]-80), size_hint = (1, None))
		self.pass_edit=vui.Edit(parent=self.login_board, text='testpass', password=True, multiline=False, size=(120,26), pos=(100,self.login_board.size[1]-90))
		self.login_button = vui.Button(parent=self.login_board, text='Login', size_hint=(None, None), size=(120, 30), pos=(100,self.login_board.size[1]-130))
		self.exit_button = vui.RedButton(parent=self.login_board, text='Exit', size_hint=(None, None), size=(120, 30), pos=(100,self.login_board.size[1]-165))
		self.exit_button.setOnClick(self.ExitGame)
		uiPhase.CUR_PHASE='login'
		return self.canvas

IntroWindow;

class IntroWindow:
	def movePhase(self,phase):
		if phase=='login':
			uiPhase.TARGET_PHASE=phase
			#self.root.clear_widgets()
			#self.stop()
			return
	def FadeIn(self):

			self.fade=3

	def build(self):

		self.bg=vui.Image(parent=self.canvas, source='bin/neuera/ui/logo/black_screen.png', size=(vui.SCREEN_W,vui.SCREEN_H), fit_mode='cover')
		self.neuera_logo=vui.Image(parent=self.canvas, source='bin/neuera/ui/logo/neuera_logo.png', size=(vui.SCREEN_W,vui.SCREEN_H), fit_mode='cover')
		self.neuera_logo.opacity=0
		taskMgr.add(self.Fade, 'intro_fade')
