[Kde-perl] Why use perlqt?

[Ole Christensen]

Kaare,

since nobody else seems to be interested to give an answer, I will try 
to depict my very limited experience.

I had to take the same decision some weeks ago. I decided to go with PerlQt.

The main reason for me was the Qt Designer. It works reasonable good 
with PerlQt and I am still using this approach. This may be very 
different with other projects and/or programmers.

Another pro for Qt I encountered is the very sophisticated Qt 
documentation. It has a really professional quality. I think noone can 
seriously doubt this point. And in my opinion this is very important.

Another point: For me Qt applications simply look better.

And now the most important point of your post. Quality of PerlQt 
(V3.008) is good but not bug free. What I encountered so far:

1. QToolTip do not fully work as expected. Refer to a previous thread in 
this list for details.

2. Method of Qt derived classes cannot return non-scalars. Refer to a 
previous thread in this list for details.

3. For me pqt-designer only works without problems (crashes) when it is 
started in same directoy as the project files. This may be due to my 
installation but other people also reported crashes with pqt-designer. 
When starting it in the working dir pqt-designer runs fine for me.


I got working patches for PerlQt for item 1. and 2. above. This also 
means: I got excellent support from the people reading the list. This is 
a very important point too. There are probably other issues left in 
PerlQt. I do not know why there is no more recent release of PerlQt. But 
since the authors do their work for free, I think we are not in a 
situation to complain about that.

The KDE bindings are not finished yet afaik. There is a cygwin package 
for Windows in the download section at sourceforge. I never have tried 
it and certainly will not. Qt for windows has a commercial license.

Summed up I would say PerlQt is worth a try. I am very satisfied with it 
up to now (~6000 lines of code so far). If you have more detailed 
questions please let me know by private mail.


Season's Greetings,

Ole.
