Symbian On-Device Debugging

**Granty** · 18th October 2010, 06:32

Hello QTs,

i am absolutley new to QT but have some C++ experience.

The problem is:

I installed QT 4.7 and tested succesfully some simple forms on the Emulator.
So far, so good.

Next I installed the qt*.sis files on my E72 to check it on the real thing.
It did'nt work out.

Then I compiled an empty form and it worked on the device !

Finally a pushbutton was added to the form, but app the terminated immediately.

I never give up: I deleted the the text from the pushbutton, compiled again and
the "app" runs on the E72.

Why is the app/form terminating withn the labeled pushbutton ?

Thanks in advance.

May be some error..
Can you show the code ?

Thanks for your swift response.

There's no code beside the QT generated.

It's just a simple form with a pushbutton.

I added no extra code to keep it simple.

I guess it can be only a setup problem. Did reinstall, but to no avail.
