I'm doing tests  on a plugin , but I can't find a way of changing text twice on a function.

 

When pressing blue button, I want to get a specific text, and after 3 seconds, another one.

 

I only get the last one.

I press blue button, and after 3 secons I get "Finished!". I don't get the first one.

 

What I'm doing wrong ???

Time.sleep is not the way hou do it in enigma2.... See the other places in enigme2 where eTimer is used....

OK. I'll investigate.

I'm trying to do a plguin to modify Yweather.py behaviour, and I need to wait some time to get downloaded xml file from yahoo.

I get it right with time.sleep , but I want to place a text before and after downloading and that's exactly what's not working.

 

Thanks,

The problem is that anything you change on the screen (via-via) won't get display until you RETURN to the "main loop". So as long as you keep waiting in your own piece of code, nothing will happen. It's a common concept in GUI-toolkits (like e.g. qt and gtk). It works with everything being called back into your code.

you do not need time.sleep or etimer

import urllib
#change button text
urllib.urlretrieve(xmllink,"/tmp/local.xml")
#change text button again
