That's right.

In my case the contents of the window is static, once it is shown it
does not change very much.

I also think it's not going to help much.

I have a strong experience with GUI programming with Delphi (Lazarus &
FreePascal for Linux) where there is the OnShow event. It is generated
when the widget is shown and in most cases its contents are already
displayed(drawn). It looks like there isn't such at-spi event.


Thanks for the hints.
