Open new window and Close it using back btn in Android toga/python

[salahshakoori20]

Hi
i created a new window from main window in Android application using this code:
new_window = toga.Window(title='new window')
self.windows.add(new_window)
secondary_label = toga.Label(text='you are in a secondary window!')
box = toga.Box(style=Pack(direction=COLUMN, padding=10))
box.add(secondary_label)
new_window.content = box
new_window.show()
this work currectly
But how to close it(using back btn Android) and how to using On_close handler of it (on_close is not implemented?)

Android (and mobile platforms) doesn't support the concept of new windows. This is a restriction of the device type - phones don't have the idea of "windows" in the same way that a desktop app does.

@t-arn I like the approach you used, is this still done the same currently or is it done another way

[freakboy3742]

There has been no change, because mobile phones don't support multiple windows with close buttons.

@freakboy3742 I'm currently trying @t-arn's answer by creating different toga.Boxes and calling them with self.main_window.content = self.box_new

@Razer-0 The basic approach is still the same. I'm using my tatogalib for all my Beeware apps: https://www.tanapro.ch/products/taTogaLib/docs/html/index.html
