how to get the status of an application called from another app.

[jthacker]

hi all,

i'm working on a simple gui design project.
in this i have made main project which shows 9 app icon in grid view like in mobile.

now when i click the miidle icon , i'm calling an application like eBook reader using QProcess, by giving the path of ebook reader to QProcess object.
with this object i can get the information that the ebook reader is running or not.

but my main target is to design a taskbar button to make ebook reader minimise and maximize (like in windows or linux).
so how can i get the information that ebookreader is minimized or maximized.

note:- i'm calling seperate executable file of ebook reader.
i'm using Qt Creator 1.3.1 based on Qt 4.6.2 in linux operating system.

thanks.
