ui.View Update

[DavinE]

Hey Guys,

I have a new Problem...
When i run "big" MYSQL Codes (one Function) i would do an Update an some Labels... when my first codes done in the Function...
but the Text and Background of the "new" Label takes effect when the MYSQL Codes are Complete finished....

Is it possible to solve this ??
thanks and greets

@DavinE, to me, the easiest approach would be to use scripter, pip install pythonista-scripter, then you can write your function like this, and the UI will be updated always when you yield:

from scripter import *

@script
def my_func(label):
    open_database()
    for loop:
        do_some_operations()
        label.text = "Some update"
        yield
    close_database()

@mikael, This looks great!
but i don't know why this function in @script works and then it don't work....

i used it in this way:

from scripter import script

@script
def test(self, sender):
	if......:
		open_database()
		close_database()
		self.barcodeNumberCheckDisplayLabel.text = getText('datanormUpdateNONE', self.DEVICE)
		self.barcodeNumberCheckDisplayLabel.bg_color = getColor('selectionNONE')
		yield
	else:
		self.barcodeNumberCheckDisplayLabel.text = getText('datanormUpdateDONE', self.DEVICE)
		self.barcodeNumberCheckDisplayLabel.bg_color = getColor('selectionYES')
		yield
		
	if......:
		open_database()
		close_database()
		
		self.ebraNumberCheckDisplayLabel.text = getText('datanormUpdateNONE', self.DEVICE)
		self.ebraNumberCheckDisplayLabel.bg_color = getColor('selectionNONE')
		yield
	else:
		self.ebraNumberCheckDisplayLabel.text = getText('datanormUpdateDONE', self.DEVICE)
		self.ebraNumberCheckDisplayLabel.bg_color = getColor('selectionYES')
		yield
		
	if......:
		open_database()
		close_database()
		
		self.cuttingCheckDisplayLabel.text = getText('datanormUpdateNONE', self.DEVICE)
		self.cuttingCheckDisplayLabel.bg_color = getColor('selectionNONE')
		yield
	else:
		self.cuttingCheckDisplayLabel.text = getText('datanormUpdateDONE', self.DEVICE)
		self.cuttingCheckDisplayLabel.bg_color = getColor('selectionYES')
		yield

is anything wrong on this ?

EDIT: When i press the button sometimes it goes and sometimes it don't goes and nothing will happened...

EDIT1: I know when the Problem is....
I Open Pythonista... Run my App call the Function then i close my App and open it again... then it don't worked
I need to reopen Pythonista then it works every Time.... but Why ?

@mikael , I’ve got a simular problem ! My animations with calls to scripter only works one time 😢. I need to restart Pythonista !
I take this opportunity to thank you for your fantastic modules. iPadOS 14.3 beta on iPad mini 4

[mikael]

@DavinE, Enez, looks like the PyPI version had a bit of a globals issue, should be fixed now.

[Enez Houad]

@mikael , unfortunately, the problem persists ! Do I need to reinstall something ?

[mikael]

@Enez-Houad, did you pip update pythonista-scripter? And maybe restart Pythonista to force re-import?

[Enez Houad]

@mikael, Yes, I’ve updated Scripter (even uninstall and reinstall) and restarted Pythonista. And now… it works the first time, doesn’t the second and crash the third !

[mikael]

@Enez-Houad, anything you could share so I can reproduce/fix?

[DavinE]

@mikael, here is a simple example:

import ui
from scripter import script
from anchors import dock, size_to_fit, attach



mainview = ui.View(name='scripter_view', bg_color='black')


Label_1 = size_to_fit(ui.Label(name='Label_1', bg_color='red', text='nothing will happend'))
dock(Label_1).top_center(mainview)

Label_2 = size_to_fit(ui.Label(name='Label_2', bg_color='red', text='nothing will happend'))
attach(Label_2).below(Label_1)

Label_3 = size_to_fit(ui.Label(name='Label_3', bg_color='red', text='nothing will happend'))
attach(Label_3).below(Label_2)

@script
def test():
	Label_1.text = 'okay'
	Label_1.bg_color = 'green'
	yield 2
	Label_2.text = 'okay'
	Label_2.bg_color = 'green'
	yield 2
	Label_3.text = 'okay'
	Label_3.bg_color = 'green'
	yield

if __name__ == '__main__':
	mainview.present('fullscreen')
	test()

the fist time it works perfect...
then close the view and reopen the view... nothing will happened..
you need to reopen Pythonista.

hope this will help you out

@DavinE, could not find a better way to make this reliable than requiring an explicit call to start_scripter, see example below (requires update).

import ui
from scripter import script, start_scripter

mainview = ui.View(name='scripter_view', bg_color='black')
start_scripter(mainview)

...

@mikael, Perfect 👏👏🙏👍
Thank you very much, I would find it hard to do without Scripter!

@mikael, It works Perfect!
Thanks for your help and work into it!
