I kind of hoped _you_ wouldn't notice my question ;-).
Well, I didn't feel well with Qt/E and FPC. To make my first application 
I modified your demo, but some things I just didn't understand, where 
they came from, what they are for,... not exactly a tranlation from C 
(not that I know much C, but when you buy a book about QT, it's using C 
and if you see contructions that are not mentioned in the book, you're 
puzzled).
The thing about the screensaver showed me something else. My C-program 
to disable the screensaver was only about 30Kbytes. My Pascal version 
was more than a megabyte big (maybe it's just a linking problem ?). And 
a number of functions didn't work so I couldn't even approach the C-version.
So I looked around for another GUI, and I found the GPE rom for the
Zaurus. But I hesitated to reflash. Then I stumbled on an industrial
PC-board : the Viper from Arcom. Since we use such boards at work I was
able to purchase a development kit. That has Tiny-X installed. Now I'm
trying to use that board to learn more about the arm-processor. But 
again I'm having problems with the GUI :-(
So is there someone who can give me a firm push in the right direction 
to solve my problem ?
