Yes, I am.

Re: Why it isn't stackable window?
 

Paste the error here, I never used Qt 4.5 in maemo only 4.6, but that works for sure.

Re: Why it isn't stackable window?
 

I am not sure if i use qt4.6 How Can i check this? This is the error.
'WA_Maemo5StackedWindow' is not a member of 'Qt'

Re: Why it isn't stackable window?
 

Try with:

#include <QtMaemo5>

Re: Why it isn't stackable window?
 

I can't include it.

Re: Why it isn't stackable window?
 

Well, without the exact error is a bit hard to guess, but probably you don't have all the packages needed. Please read the links that I've posted here and perhaps is better install Qt 4.6, since is more compatible with Maemo5.

Re: Why it isn't stackable window?
 

Thank you. I have a eclipse. What upgrade to qt 4.6?

I installed qtlib4-maemo5-dev and I get this error 'WA_Maemo5StackedWindow' is not a member of 'Qt' in eclipse. What is wrong?

Re: Why it isn't stackable window?
 

Probably your setup is not correctly configured or some packages are missing. Did you followed the instructions in the page that I posted here ?
You also need, at least, 'qtlib4-maemo5-maemo5', try also to compile your app directly under scratchbox to see if the problem is in your esbox setup, don't forget to use qmake under '/opt/qt4-maemo5/bin/qmake' since you're running Qt 4.6.
