Hi David
You are pointing your finger at the wrong place. The blame (if any),
belongs to Qt and not Jolla.
Jolla made the sensible decision not to reinvent the wheel. Instead
they chose to leverage Qt, which is a strong contender as the de-facto
multi-platform development toolkit, and one which is gaining
increasing traction as the number of mobile platforms it supports grows.
Qt is programmed with a cocktail of C++, descriptive QML and Javascript.
Typically QML is used for the GUI stuff, Javascript for simple logic,
and C++ from backend "heavy-lifting".
Depending on the nature of your project, and your preferences and
experience you will have a different mix of these 3 languages /
idioms. It is quite possible to create a Qt project with no more C++
required than that generated in the default project. (I only use C++
when I really can find no better way, while others will opt for a C++
driven project).
Python is an alternative with bindings to Qt. If you search the
archives of this mailing list you will find many questions on Python
and Qt / Sailfish. So it is there, and it is being used, and there are
ardent fans of Qt + Python out there.
The interesting question is, why did the original creators of Qt opt
for C++, rather than the more obvious Java? I suspect that the answer
is in the multi-platform ethos of Qt. Quite simply there is an open
source C++ compiler available for almost any architecture you can
think off, which is not the case for Java, especially in the mobile
arena.
You should not find QML hard to learn, and if you have Java /
Objective C experience, then I don't see why a limited amount of C++
should put you off.

Zitat von "David Jensen" <davidjen...@usa.net>:
Nokia's original book on Meego featured, I think, Python as the
development. I
do not see this book on Amazon. However, almost none of the articles I have
seen relating to Jolla mention Python. I assumed Nokia believed
Python was an
ideal language for an open system that was easily modifiable by
others. I get
the impression the language is C++. This is more difficult than Java and
possibly also Objective C. How does Jolla expect their system to be
adapted as
open if the language developers have to deal with is C++, with Python a vague
afterthought?
