Trying to change label.text

[philippe]

Hello everybody
Labels have text attribute so I suppose it’s possible to change that but Labels don’t have action line in the GUI, no function to link with.
Is there a way to access Labels and other windows in the view via ui ?

Here you can find the manual for the ui module and a tutorial.

@philippe as usual, not sure I correctly understand your request.
Try this code. It uses the name attribute of the label to be accessed in the button action

import ui

v = ui.View()
v.frame = (0,0,400,400)
v.background_color = 'lightgray'

l = ui.Label(name='label')
l.frame = (10,10,380,32)
l.background_color = 'white'
l.text = 'initial'
v.add_subview(l)

b = ui.Button()
b.frame = (10,50,380,32)
b.background_color ='white'
b.title ='change label text'
def b_action(sender):
	b.superview['label'].text = 'new text' # b.superview is v, v['label'] refers thus to your label
b.action = b_action
v.add_subview(b)

v.present('sheet')
