Qt 5 comments??

[nish]

I was digging in Qt sources for some reason, and noticed Qt 5 comments... So what do you think? When we will get Qt 5? Just curious...:)

give it a try in src folder..


grep -srn "Qt 5:" .

here is the little bit of output (not full due to post char count limit)

I was digging in Qt sources for some reason, and noticed Qt 5 comments... So what do you think? When we will get Qt 5?

Unfortunately, that are just comments and helper not to forget what the trolls intend to do till Qt 5. Out of that you can't interpolate a release date...

[nish]

i think they want to say what will they do in Qt5 rather than intend to do till Qt 5

[wysota]

When we will get Qt 5? Just curious...:)
2011/2012, as far as I can see from my notes. At least that was the plan two years ago, things might have changed since then.

thats too late.. when we had qt4?... in 2005? its already 4 years... Nokia(TT) is trying to break the Mirosoft record of delay Vista or what?:)

[wysota]

Time span between Qt3 and Qt4 was also about 5 years (3.0 was released in 2001, Qt4.0 was quite buggy so let's consider 4.1 as the first mature release and 4.2 as the first feature-complete release). The leap between Qt4 and Qt5 in terms of functionality will be greater than between Qt3 and Qt4 because it has to be done without changing the API so drastically as it was the case last time. Furthermore there are still lots of things to be done for Qt4, so let's not hurry with Qt5. With Qt5 the greatest challenge will be to provide means of thread-safe rendering. With Qt4 the greatest challenge (apart of rewriting everything from scratch) was to provide per-thread event loops and thread-safe signals and slots.

4.4 was a big bang.. we never had 3.4 .. may be 4.4 could be taken to 5.

[wysota]

Qt4 still has a long way to go.

ya.. i m waiting for Qt3D

I cant believe it!! Your notes proved to be exact!!. How you got such insider information :D.


PS-> sorry for bumping the thread.
PS2->@Admins,Mods, when we will get a official thread about QML/JS in Qt5?

I was listening carefully to what Lars had to say during his presentation at DevDays 2007.

I don't see any reason why we couldn't continue the discussion in this thread.

silly me :(.

may be the title of the thread does not reflect about the situation today. Anyways.. QtWidgets.so.5.0.0 would be the jail for the old QWidget/QPainter magic i learned in so many years. JavaScript? let me see how i can code in it.
