Get current screen or orientation width?

JonB

In the new ui module, is there a way to get screen width?
Or, to change popover location to a different corner? For instance, by default popover goes to top right... How would I go about moving it to the bottom right, and have it stay there across orientation changes?

Sebastian

Can't you just get the width by using root_view.width?

JonB

If I could find such a root_view, then yes. Superview() on a view returns nothing. I couldn't find anything in the ui module that looked like screen width

It's not really possible, I'm afraid. You can't change the location of a popover after it's been presented, and there's no good way to determine the current device orientation (and ui.get_screen_size is orientation-independent, so that won't help).

JonB

Sheesh, not sure how I missed ui.get_screen_size ... that's what I was looking for. Thanks!

Actually, get_keyboard_frame changes with orientation, so can be used to determine orientation. I was trying to put a pop up near they console entry, so that'll work perfect.

For what it's worth:

ui.WebView().eval_js('window.orientation')

Returns the orientation (0,90,180, 270), so is an easy way to get orientation!

What am I doing wrong?

import ui
print('\nRotate your device to see the various orientations.')
old_orientation = None
while True:
    new_orientation = ui.WebView().eval_js('window.orientation')
    if old_orientation != new_orientation:
        print('Screen orientation is {}.'.format(new_orientation))
        old_orientation = new_orientation

@ccc I think you need...

import ui
print('\nRotate your device to see the various orientations.')

v=ui.WebView()
v.hidden = True
v.present('panel')

old_orientation = None
while True:
	new_orientation = v.eval_js('window.orientation')
	if old_orientation != new_orientation:
		print('Screen orientation is {}.'.format(new_orientation))
		old_orientation = new_orientation

Note: it gives -90 not 270 (I'll update the code I posted for JonB in the Unsupported File Type thread)
