As you have guessed, we no longer officially support Qtopia. The last released version was named Qt Extended 4.4.
While you may not have found any info specifically related to your board, this is not that strange because Qt doesn't contain anything specific to a particular hardware board. Qt supports the ARM architecture you are using as well as your kernel version so that is most likely enough. Assuming that you have a working cross-compiler installed on your host PC, then the next step is to download and cross-compile Qt Embedded using the device's toolchain. I recommend starting here:
Getting things like the touchscreen working may require some tinkering, but you might be able to find some code for this in the Qtopia package released by the manufacturer. It could be as simple as porting their Qt 2 based code to Qt 4.
If it is acceptable for you to open external application (not software component) than you can use QProcess.
If you want to use WMP as software component than you should look for phonon plugins working with WMP.
Qt uses the native file dialog on Maemo 5 ("Maemo docs":http://maemo.org/api_refs/5.0/5.0-final/hildonfm/HildonFileChooserDialog.html), which disallows browsing anything but the home dir and the memory card. To browse the entire file tree (and risk being rejected from the Ovi store), you can use a QFileSystemModel on a QTreeView?
[quote author="silvansky" date="1278666566"]for now there is QT_SIMULATOR macro for source files (in the latest Nokia Qt SDK)
but I don't know if there is somethong for .pro files
in .pro files you can use
# do something
Yes, indeed. And don't be fooled, the KDAB stuff, including KD Charts, are available under GPL, even if KDAB does not advertise it that way.
My experiences with KD Chart are pretty decent. There are some weird inconsistencies, but all in all its not bad at all.
I found a possible solution but I don't know how to use it...
The solution consist in using QSvgRenderer::boundsOnElement .
It seems that it's possible to render only a part of the svg identified by the Id.
The step should be:
render the svg in a QImage
update the element in the original svg
render the changed part (with boundsOnElement) in the same QImage
Now I must study how to put the changed element in the same place of the background image to cover the old element.
I tried Nokia QT SDK for Linux online version and now qtcreator works:
@luca@slack131:~$ cd NokiaQtSDK/
so I think there are some problem in offline version...
[quote author="QtK" date="1277479535"]Never tried it on Linux yet. But note that you cannot develop applications for Symbian Platform using Nokia Qt SDK linux version.[/quote]
This is a big limitation...
I hope to have soon a complete linux sdk version.
[quote author="maurizio.moriconi" date="1274699465"]Qt also run on other mobile platforms (openmoko for example).[/quote]
It does indeed and it also runs on embedded platforms that are not related to phones at all, like coffee machines and printers. :)
