Incremental textView content

[rb]

Next question:)
Is it possible to animate the .text attribute of a ui textView?
Ie print the text one letter or a few letters at a time?
Any pointers on how best to do this?

@rb Not sure it is what you want

import ui
full = 'this is the entire text'
tv = ui.TextView()
tv.text = ''
tv.present('sheet')
def animation():
	global full
	tv.text = full[:len(tv.text)+1]
	if tv.text != full:
		ui.delay(animation,0.2)
ui.delay(animation,0.2)

@rb or

import ui
class mytv(ui.View):
	def __init__(self, *args, **kwargs):
		super().__init__(*args, **kwargs)
		self.update_interval = 0.2
		self.tv = ui.TextView()
		self.tv.text = ''
		self.add_subview(self.tv)
		self.full = 'this is the entire text' 
	def update(self):
		self.tv.text = self.full[:len(self.tv.text)+1]
		if self.tv.text == self.full:
			self.update_interval = 0.0		
v = mytv()
v.present('sheet')

Thankyou! Exactly what I wanted - delay() was what I needed

@rb, note that in my experience, using the update method is more stable.

And if you are going to be adding lots of these small nice animations, I will plug my Scripter module, that e.g. has reveal_text available as a simple function to call on a textual view.
