Python Pannable Area scroll_to_child

[nux]

Can someone help to understand why I can't to "scroll_to_child" after initialization.

got this (http://wiki.maemo.org/PyMaemo/UITutorial/Navigation#Additional_features)example and modified it but no luck.
If the same function is called from button click, it is working :confused:
Can someone point to right direction :)

Attached python code:

Hey

Figured it out, even there is that you should connect to 'realize' event, correct is 'map' event :)

It seems that pannable area scrolling after initialize is not working if window is already visible.

Attached a sample code and if you uncomment line 61 it is not working anymore :(
But via button click then the same code is working.
And in both cases widget is maped and realized.

Can someone experience with python comment this?

It seems that pannable area scrolling after initialize is not working if window is already visible.

One possibility is that scroll_to_child() only works reliably after the event loop has started. You might use gobject.timeout_add() (or gobject.idle_add()) to add the scrolling as an asynchronous event.

I attached a (working) example showing how to use gobject.timeout_add(). In the example the pannable area scrolls to a random button every 2 seconds.
