ui.dump_view() function?

RocketBlaster05

I'm trying to remove a loaded ui view from the screen after a button is pressed. I assumed that ui.dumpview() would remove said view but it keeps giving me an error saying "Expected a ui.View or subclass." Am I even using this function properly? If not, is there another way of removing a loaded ui view from the scene? I have tried all different names for the ui.View I am using and it does not seem to register it.

Thanks!

@RocketBlaster05 never seen dumpview. I know dump_view but it does not remove a view.
Did you try your_ui_view.close()?

RocketBlaster05

I used ui.load_view("MainMenu") with the present and such. I want to call on it to close but it says that MainMenu isnt defined. Is there somewhere else I have to define it?

cvp

@RocketBlaster05 yes, use

mm = ui.load_view('MainMenu')
.
.
.
mm.close()

RocketBlaster05

@cvp It... isn't closing it. I have it defined and there is no errors yet it refuses to close the view. I'm getting really confused right now lol. I'll keep looking at it but it just doesn't seem to want to work.

cvp

@RocketBlaster05 could you paste your code here or, if it is big, paste a link

cvp

@RocketBlaster05 is the view presented? You can only close a presented view

@cvp

#all necessary imports are present already. 
class Menu (ui.View): #main menu setup
   def __init__(self):
       ui.View.__init__(self)
       self.scene_view = scene.SceneView()
       self.present(hide_title_bar=True)
       self.scene_view.frame = self.bounds
       self.add_subview(self.scene_view)
       ui.load_view(‘MainMenu’).present(‘fullscreen’, hide_title_bar=True)

def button_tapped_learn(Learn): #button on ui
    LearnText() #scene for what I am trying to present
    ui.load_view(‘LearnPage’).present(‘fullscreen’, hide_title_bar = True) #ui I want to present
    ui.load_view(‘MainMenu’).close() #line that doesn’t work but doesn’t give me an error. Tried subbing it for mm and other nicknames.

class LearnText (Scene):
   def setup(self):
       self.background_color = ‘white’

if __name__ == ‘__main__’:
   Menu()

class LearnText (Scene):

And just as a heads up, all of this code works as intended except for the close function

cvp

@RocketBlaster05 you didn't pass via a variable
Thé ui.load_view(‘MainMenu’) that your presented is not the same object as the ui.load_view(‘MainMenu’) that you close

       self.mm = ui.load_view(‘MainMenu’)
       self.mm.present(‘fullscreen’, hide_title_bar=True)
.
.
.
       self.mm.close()

cvp

This should work but without the pyui files, I can't test

class Menu (ui.View): #main menu setup
   def __init__(self):
       ui.View.__init__(self)
       self.scene_view = scene.SceneView()
       self.present(hide_title_bar=True)
       self.scene_view.frame = self.bounds
       self.add_subview(self.scene_view)
       self.mm = ui.load_view(‘MainMenu’)
       self.mm.present(‘fullscreen’, hide_title_bar=True)

def button_tapped_learn(Learn): #button on ui
    global m
    LearnText() #scene for what I am trying to present
    m.mm.close() #line that doesn’t work but doesn’t give me an error. Tried subbing it for mm and other nicknames.
    m.mm = ui.load_view(‘LearnPage’)
    m.mm.present(‘fullscreen’, hide_title_bar = True) #ui I want to present

class LearnText (Scene):
   def setup(self):
       self.background_color = ‘white’

if __name__ == ‘__main__’:
   global m
   m = Menu()

@cvp yes this worked very well! It closed it out but now it says there is an animation in progress or there is a view already presented specifically with the m.mm present line

cvp

@RocketBlaster05 perhaps you could insert a time.sleep(0.2) between the first view closing and the new view presenting

RocketBlaster05

@cvp I have tried the sleep function but it freezes the close animation as well. I can only assume I'd have to move the loading portion around or something. I hope I find this soon because my app will have a lot of UI in it and this is a very important part lol.

cvp

@RocketBlaster05 could you try this

def button_tapped_learn(Learn): #button on ui
    global m
    LearnText() #scene for what I am trying to present
    m.mm.close() 
    ui.delay(start_LearnPage,0.2)
    
def start_LearnPage():
    global m
    m.mm = ui.load_view(‘LearnPage’)
    m.mm.present(‘fullscreen’, hide_title_bar = True) #ui I want to present

RocketBlaster05

@cvp Finally! This is working perfectly! However I must say that either due to my Ipad or the length of the close() animation the shortest time I can get this to consistently work is 0.55 seconds. It is not an issue and I think it will be just fine. Thank you so much!

cvp

@RocketBlaster05 😅

@RocketBlaster05 if you have several views with same kind of process, you could avoid additional def for each view by

from   functools import partial
.
.
.
def button_tapped_learn(Learn): #button on ui
    global m
    LearnText() #scene for what I am trying to present
    m.mm.close() 
    m.mm = ui.View(name='LearnPage')
    ui.delay(partial(m.mm.present,'fullscreen', hide_title_bar = True),0.55)
