Can you provide a more complete example?

[quote author="GordonSchumacher" date="1292033566"]Do any Android and M(aem|eeG)o devices actually have swap?[/quote] I don't own any android devices, so I can't comment about those, but Maemo5 (and I would guess all earlier Maemo releases) have swap, and both MeeGo handset and netbook profiles have it enabled, yeah.

thanks all for your attention. It's so nice.

hi, Sorry for delay I was out of station for some urgent. I have tried the way QTK said, and that worked like a charm, thanx for that mate. The only problem I am getting is I getting two icons for both application, I mean sis file and wrt file, The application is one , Is there any way I can remove one icon, or in other way to say is , Is there any way I not put the app icon in application folder? Thanks.

Okay, thanks for the report. :)

Ok. Great (that it wasn't Qt issue, too bad for your HW).

[quote author="xsacha" date="1291911324"]If it has basic capabilities and you just want to put it on the Ovi Store, there is no signing process. In the Content Item, just upload the unsigned app with the provided (from Nokia's email) UID that you used to compile it. Note that Qt apps have to use SmartInstaller. This used to be fairly complicated but QtCreator 2.1 handles all of the work for you now. It has fields for dev cert/dev key/UID3/SmartInstaller when you create the project.[/quote] If you self sign the application - a warning message would be shown to the user. If you are ok you can skip symbian signing for apps with basic capabilities.

It was a problem with QString to float conversion in my code, I had to do this: @ //t1 and t2 is QStringList's #ifdef Q_WS_WIN targetpoint1 = new QPoint((t1[0].toFloat()*32),(t1[1].toFloat()*32)); targetpoint2 = new QPoint((t2[0].toFloat()*32),(t2[1].toFloat()*32)); #endif #ifndef Q_WS_WIN targetpoint1 = new QPoint((t1[0].replace(",",".").toFloat()*32),(t1[1].replace(",",".").toFloat()*32)); targetpoint2 = new QPoint((t2[0].replace(",",".").toFloat()*32),(t2[1].replace(",",".").toFloat()*32)); #endif@ I don't know if there is a better solution to this..

Gordon, the link is broken - it points to an non-existing page. Maybe a typo?

[quote author="mario" date="1291903011"]Yeah, I need my QML to create UIs :)[/quote] You can create it now, but will have to wait to publish it to OVI. May be by the time you are ready with your app - ovi would support QML apps.

Although not completely relevant, but you can still refer to "this":http://www.forum.nokia.com/info/sw.nokia.com/id/97e9b8e0-904c-4141-bb8a-91d4f519735f/Maemo_5_Desktop_Widget_UI_Guidelines.html document on desktop widget UI guidelines for Maemo.

Hi,amppa. Now I have the problem is that I can't play mp3 via network. I can play local mp3 using Phonon or QMediaPlayer of Qt Mobility.

[quote author="Bradley" date="1291882027"] [quote author="Wolf P." date="1291881681"]...BTW: I added a tag "all-purpose qml":http://developer.qt.nokia.com/search/tag/all-purpose+qml for collecting QML vs. traditional questions...[/quote] I don't understand how "all-purpose" refers to QML vs widget-based UIs. [/quote] I seached for a tag addressing the comparison between QML and "traditional" UI programming. maybe qml vs widget-based would fit better, where "widget" means two ways: using ui files programming UI in C++ Maybe we start better a wiki article to collect informations about this complex decisions. since we have not combined tag search, tags combining word are useful. I'm no trying with "qml vs widget" :)

In a similar vein, and using nearly identical code to that above, i'm trying to get my N8 to recognize a long press (QTapAndHoldGesture). I've tested this on Windows using the simulator and it works just fine with no activity until the Hold expires. However, when I try this on the N8 the timer never seems to fire (QT 4.6.x by the way). Here's the behavior i'm experiencing: If I lift off before the Hold period expires I receive the cancel. If I lift off after the Hold period expires I receive the gesture If I don't lift off then nothing happens If I move out of the hot spot i receive a cancel - Then a started & finish event as I lift off. Given this works on the simulator (qt 4.7.x) I'm guess it's a problem with Qt 4.6? Any help would be gratefully appreciated

Hi, I am also new to Qt...was gonna ask this same question here. @above - thanks for the links. will check

Thanks. So it will still consume a lot of memory during runtime anyway. What I'm looking for is real small size. [quote author="Gerolf Reinwardt" date="1291809998"]With upx you compress the excutable, not the setup. So the resulting executable stays smaller. If it is uncompressed, then during runtime, not during installation.[/quote]

But you only have objects, if you use QTabelWidget, what do you do with QTabelView (which is the defacto base)? I think, QTableView should be used more that QTableWidget, especially, as it allows custom models. So you would need to specify dataRoles in the style sheet to get the needed info to style the item. That would get really strange I think.

Hi John, Unfortunately the API doesn't allow application specific attributes to be stored. This was a limitation of the underlying platforms. As to a suitable workaround, each landmark has local id(inside QLandmarkId), it may be possible to use this to associate the landmark with application specific data in an sqlite database. Care needs to be taken however since other applications may remove landmarks leaving the sqlite database out of sync. I'm not sure I understand how associating the ptr of a landmark with a guid will be helpful since the memory address of an object (a landmark object in this case) is not persistent. I agree though that the utility of the API is limited, hopefully we can address this shortcoming in a future release. Your feedback will certainly help with that.

thanks. It seems we should upgrade the system.

hey hisong1988, thank you for the follow up. ;) hlima, did you report it in the "Qt bug tracker":http://bugreports.qt.nokia.com ? If so, remember the number?
