[Interest] How to disable "Semantic Issue" marker in qtcreator ?
Hi, I'm using qtcreator only for debugging. I always get "Semantic issue" markers beside the source code line numbers, which interferes with the breakpoint markers. See attached screenshot. One can not easily see what is a breakpoint. I want to get rid of the display of the "Semantic issue" markers completely but find no setting which allows to do so. Any hint ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?

This is what I already found, but Qt Support told me I'm wrong and the QSceneLoader can not load blender files. So, who is right ?

Hi,

I think I will have to recompile Qt to do this with the CONFIG option as

I think if your win application is a console application, it will instead
already
print the output to stderr or stdout (don't know).
You can also redirect qDebug() messages:
void myQtMessageOutput(QtMsgType type, const QMessageLogContext context, const
QString msg)
{
// whatever shall be done with the message
}
main()
{
qInstallMessageHandler(myQtMessageOutput);

[Interest] How to use QtPositioning on Android
I'm trying to use QGeoPositionInfoSource on Android with Qt5.3.1 built on a Linux Box using Ministro. When I do this with a simple test program using qtcreator, QGeoPositionInfoSource::availableSources() shows android, which is fine. However, testing with our large application, it gives an empty list. As the large app does neither use qtcreator nor qmake (we use cmake), can someone tell me what I need to configure (AndroidManifest.xml or any other .xml file) so that my app shows the available android positions plugin ? Note that I want to use Ministro. I see in the test app's AndroidManifest.xml file the following lines, however I can not find any documentation about what these lines are good for (especially the ones mentioning QtSensors.jar and QtPositioning.jar). What do they do and how do I need to use them. meta-data android:name=android.app.use_local_qt_libs android:value=0/ meta-data android:name=android.app.libs_prefix android:value=/data/local/tmp/qt// meta-data android:name=android.app.load_local_libs android:value=plugins/platforms/android/libqtforandroid.so:plugins/sensors/libqtsensors_android.so:plugins/position/libqtposition_android.so/ meta-data android:name=android.app.load_local_jars android:value=jar/QtAndroid.jar:jar/QtAndroidAccessibility.jar:jar/QtAndroid-bundled.jar:jar/QtAndroidAccessibility-bundled.jar:jar/QtSensors.jar:jar/QtSensors-bundled.jar:jar/QtPositioning.jar:jar/QtPositioning-bundled.jar/ meta-data android:name=android.app.static_init_classes android:value=org.qtproject.qt5.android.sensors.QtSensors:org.qtproject.qt5.android.sensors.QtSensors:org.qtproject.qt5.android.positioning.QtPositioning:org.qtproject.qt5.android.positioning.QtPositioning/ It's also not clear if these lines are used at all when using Ministro.

The Qt namespace has a lot of enums like that. The trick there is to get
moc to pretend that the namespace is actually a class.
src/corelib/global/qnamespace.h
This is not what I meant.
The Qt namespace defines enums on its own and the MOC-Hack (#if
defined(Q_MOC_RUN)) just makes sure that the enums
can be used in Q_ENUMS
What I need is a FOREIGN enum, e.g. one which is already availabe in a
different Qt header, but the enum is not
part of a QObject derived class.
E.g.
#include QSslError
class MyClass : public QObject
{
Q_OBJECT
Q_ENUMS(QSslError::SslError) // does not work
};
#include moc_test.cxx
In file included from test.cxx:9:0:
moc_test.cxx:66:10: error: ‘staticMetaObject’ is not a member of ‘QSslError’
QSslError::staticMetaObject,
You can add fake poperty with type QSslError::SslError, and access enum via
QMetaProperty::enumerator()
That does not work.
The doc says: The enumeration type must be registered with the Meta-Object
System using the Q_ENUMS() macro.
but doing so leads to above compile error.
Not using Q_ENUMS(QSslError::SslError) in MyClass does also not work, as
QSslError::SslError is an enum
from a class which is not QObject derived.
The doc says: Had the enumeration type been declared in another class, its
fully qualified name (i.e., OtherClass::Priority) would be required, and that
other class would also have to inherit QObject and register the enumeration
type there using the Q_ENUMS() macro.

What do I need to do in my QPA plugin so that a widgets has a
nativeParentWidget() ?
It seems I solved it now. Looking into the vnc plugin, I see that it just
generates non-zero winIds
in a derived class of QPlatformWindow:
static QAtomicInt winIdGenerator(1);
windowId = winIdGenerator.fetchAndAddRelaxed(1);
and returns this in
virtual WId winId() const { return windowId; }
So I also implemented my own QPlatformWindow derived class.
