[Kjow]

WOW, thank you!

I will try as soon as possible, in this period I have no time for
developing on N900...

> The patch accommodates for the following:
>
> * Qt on N900 Maemo5 is compiled w/o support for:
>  - printing
>  - trayicon
>
> * Qt on N900 Maemo is compiled w/o deprecated functions.
>   The following list shows the deprecated functions used by
>   LCL/Qt and their new counterpart.
>  - QRegion_numRects -> QRegion_rectCount
>  - QImage_numBytes -> QImage_byteCount
>  - QPaintDevice_numColors -> QPaintDevice_colorCount
>
> I acknowledge that the patch can be considered as
> fairly intrusive, if you know a better way, be my guest.
>
> Detailed instructions are not ready yet for this Release Candidate.
> For the adventurous:
> - the binding can be compiled in scratchbox. It is just Qt C++ code,
>  no need for fpc in scratchbox. Nokia has excellent documentation
>  for the installation of scratchox. After a full installation do a
>  fakeroot apt-get install libqt4-dev
> - copy the library to /opt/usr/lib and make links to /usr/lib ("optify").
> - Strip the library first to shave of some bytes.
> - compilation can be done on the device (fast enough) or using
>  fpc cross compilation outside scratchbox. Add a -dMAEMO5 to
>  ppcarm to enable the maemo specific functions in qt4.pas.
