[Qt] QT patch

Sun Jan 7 05:01:29 CET 2007

I would suggest we use 1.26 since the 1.24 qt4.pas doesn't work with the currently posted libqt4intf.dll (1.26) on Windows.

However, the 1.26 qt4.pas doesn't seem to want to compile against 4.1.4 so I'm building Qt 4.2.1 tonight and will test it tomorrow. If it works okay I'll send Den a new Qt4Intf framework to post.

Compiling your patched Qt units with the 1.26 qt4.pas fixed some of the problems I was seeing with FPC 2.1.1 on Windows (but not all), so maybe the problem is not with FPC 2.1.1.

Thanks.

The Laz shipping Qt files didn't support everything, as the missing
support is being added some features would seem are not working, this
is normal because simply I cannot test everything. I could miss
something a flag here of there, I would need test projects to advance
on completing the missing support and at the same time to try not
breake things.

Also the patch is large, many things were changed. I think first it
should be approved in general, I don't see the point in continuing to
add features if current structure and methods are not likely to match
everybody's idea of qt interface improving.

I will take a look, but see my last comment above.

So, what are the recommended versions of bindings and library for all
os? considering that shipped lazarus bindings should be upgraded. 

I'm new to Den Jean releasing of bindings and I might have
misunderstood something. If I got it right 1.24 is stable and 1.25 is
beta I choose stable and I haven't find any problem with my qt4.2.2
library at least under linux (though I don't really remember if 1.25
was out when I started).
