Brainstorm

Yes, in fact they hide when performance is sub-optimal. I read this thread a long time ago (before I was registered on here) and implemented it using Qt4.7. There's a workaround, involving adding a timer (first reply shows how to do it). It works quite well as a notification for loading files/images and such. I really wish more developers used it -- especially on Windows/Symbian where you get annoyed by boxes all the time.

xsacha: I do not get your point(s).

The best is to have open books as made available in symbian.org wiki. Any updates any one can update it.

I agree something like this might be nice. However, it seems like an opportunity for a third-party commercial or community project, rather than a Nokia Qt project. I'd hate to see Qt development resources go toward it. It should be possible to build something like LightSwitch on top of Qt without core changes, and there are many other advancements for the Trolls to work on, which would help the larger Qt community.

I agree with Tobias above: this seems to be the territory for third party widget providers.

I had a closer look at the Cola wiki. It uses the Eclipse Communication Framework (ECF), which seems quit big. Didn't find anything similar in Qt Creator. Seems to be a bigger job than I first thought.

nice answers :), understood and thanks for help.

Denis: Currently there are no plans for that. In fact you are the first to mention a preference for Ctrl-5 that I am aware of.

Thank you very much. I try it the way you suggest me and worked perfectly :)

Thanks MariusG, it is very helpful to me......

pushpendrak: Check the "shop":http://shop.qt.nokia.com/en/product-licenses.html for pricing information. The trolls here tend to be developers and most are not really aware of the current pricing schemes (at least I am not:-). Depending on what you want to do you may even be able to use the open source license, so you might want to check that first. Since I am not aware of any Qt 5 related planning can not tell you whether it makes sense to wait for it or not.

[quote author="Tobias Hunger" date="1284381360"]You might want to file a wishlist item in our "bugtracker":http://bugreports.qt.nokia.com/. That is the best place for stuff you want to see in future releases.[/quote] Yes, i know but i think this is the place for tell about idea...

yes felix, the same is approach is taken in the example I mentioned

Question : if you just don't have the required memory, can you do something to prevent the crash? Something like: send a warning to the user "you should save your data... memory shortage coming soon... crash following" release unused objects... is impossible in most of the cases manage by yourself an of the core strategy (hand made HD swap) ... In most cases, you don't need to wait until the last kb is used. Allocation tests can be performed on big allocations and the turnaround strategy (if any) can be started when more than 80% is used.

Excellent resource list. Thank you guys

Thank you so much for such a quick answer.

@Can we use *.a files(lib) on windows based project.@ No we can't we've to use lib Problem solved :)

I have a follow on question about data sharing and a QImage. If I create the QImage from a pointer to a unsigned char in memory (and a width and height argument), is it possible to change the pointer withing deleting and re-creating the QImage? Data sharing seems to say that it doesn't copy the data until you try to write to it (which I won't do). I have a circular frame buffer of images that are being filled by the camera. In my paintevent method, i'm currently creating and destroying qimages.. Would it be faster to re-assign the memory location to the image data? Is that possible once the qimage has been created? I'm new to the use of this data structure and want to make sure I'm using it as intended. Thanks!

good luck with that and keep us posted how it goes :)
