Then just delete the build folder and start from scratch

Thank you for this post, I've been battling the same issue recently :-)

Sorry everyone, I have solved this problem. I change my code: Before: thisDB = QSqlDatabase::addDatabase(“QSQLITE”,dbName); After: thisDB = QSqlDatabase::addDatabase("QSQLITE"); thisDB.setDatabaseName(dbName); It just work by now. Thank you.

i've installed the Jack audio but a message error appears: needs connect to X server actually im working in ubuntu armhf 12.10 without desktop environment or X-server i don't know if there another way to use phonon without Jack Audio

Please see, e.g. this: https://codereview.qt-project.org/#/q/status:closed+project:qt/qtconnectivity+branch:wip/win,n,z

Hi a clear view of the code in previous msg @class Location : public QObject { Q_OBJECT public: Location(QObject *parent = 0) : QObject(parent) { qDebug() << "Position created:"; if (source) { source->setPreferredPositioningMethods(QGeoPositionInfoSource::SatellitePositioningMethods); connect(source, SIGNAL(positionUpdated(QGeoPositionInfo)), this, SLOT(positionUpdated(QGeoPositionInfo))); qDebug() << "Source created:"; source->setUpdateInterval(1000); source->startUpdates(); } } private slots: void positionUpdated(const QGeoPositionInfo &info) { qDebug() << "Position updated:" << info; } }; @

i put the pushButton onto the widget insteads of reverse. It work :>>> Problem solved :>>>

Thank you ed

What I found out so far is that Androids Java API can list all paired devices and open a connection without running a device discovery process. On Linux, I can run the command "bt-device -l" which immediatley returns a list of known devices (address and name). How can I get a similar list via QBluetooth wihtoud running the time-consuming discovery process?

The bluetooth chat example (of Qt 5.3) works fine on my Netbook with Ubuntu 14.04 and a HC-06 module. I only had to enter another UUID in chat.cpp: static const QLatin1String serviceUuid("00001101-0000-1000-8000-00805F9B34FB"); Edit: It works fine also on my mobile phone, which is an Huawei G525 with Android 4.1.2. The only thing that I don't like is that I must run the lengthly discovery process in order to list the names of available devices.

I do not know how to avoid anchors and get the progress bar to change size with the parent object size (be it a window or simple rectangle). If I use just a progress bar without a ProgressStyle, then I'm limited to whatever the base OS style is, and can't even change something like the color of the bar. If I try to set the intrinsic properties of ProgressStyle on the fly, they get set once, and then forever afterward they are the same. I am having some luck just doing this myself with rectangles, and avoiding the progress bar altogether. Thanks. Brian

Hi JKSH, Don't really have time to compile Qt 5.4 yet. Still waiting for the Mac binary. However, I have checked the patch. The provided widget set should be different. So I will focus on those components not provided by Qt 5.4 (like navigation drawer) or the things I need for my project now which can not wait for Qt 5.4 release. Moreover, another objective of this library is the style classes and utilities to create custom component for your own application that look like an Android native application. For example , I have asked will it provide the "DP" unit by Qt in mailing list. The answer is no. But you need this value otherwise your software will not looks like native application. QuickAndroid is not a replacement / duplicated feature to Qt 5.4's native widget support. It is more like an add-on library which could be co-existed with Qt 5.4.

The GUI might be, but still, driver writing is outside the scope of this forum

is there any link that you can direct me to?

Before anything else, if you're not tied to that particularly old version of Qt you should first update to 4.8.6

Thanks for the hint. I have already checked this and looked at it. It's based on udev. Since my device uses busybox with mdev, I decided to not try to make this run and try my own solution instead.
