I have Qt 4.1.0 Open Source @ Fedora Core 4
I want Qtopia 4, so i downloaded the "qtopia-core-opensource-src-4.1.0.tar.gz"from trolltech site and configured it.

I am able to run the example program in the Qtopia directory and it is
using 'qvfb' tool provided by Qt 4.1.0.

Now, My question is the Qtopia examples are using QPEApplication or not,

I think Qtopia 4 does not need QPEApplication, is my assumptions right?

If not, kindly give me a small "Hello world" Qtopia sample Program and
steps to compile and run it on qvfb

Many Thanks

I have some things for you, although they are not directly related to your questions:

Qtopia is like a set of additional classe for Qt. They run on top of Qt/Embedded and provide a window system and some more stuff, making an environment for Qt-programms to run. On other plattforms, you have the native window system, application launcher and so on, on embedded linux you don't have and thats the part Qtopia takes. Qtopia was based on Qt 2, there was never a version based on Qt 3 although there was Qt/Embedded based on Qt 3. I think a few days ago Trolltech released a version of Qtopia based on Qt4. Starting with the Qt 4 series, Qt/Embedded is renamed to Qtopia core.

I think Qtopia 4 does not need QPEApplication, is my assumptions right?

Why should it not need it?

Thanks Axe,

Finally I got some idea from you Thanks a lot...

BTW, answering to your question ...

I downloaded qtopia-core-source from trolltech site and installed it as per instructions..

the examples given are running on qvfb with out any problem..
when i see the source code, i find all examples are using QApplication instance and
not using QPEApplication instance...

That's Y i asked that question or made that assumption

what is your comment

Trolltech renamed 'Qt Embedded' 4 to 'Qtopia Core'. It's still the same code, and it doesn't have QPEApplication classes.

so for QTE4, QApplication will work with out any problem, right?

Thanks for the answers and time spent

"Hello Alarm", 123);

AlarmServer waiting 329 seconds
