Dear All
My display resolution is 800*480,
I write a qml like that:
import QtQuick 2.0
Rectangle {
width:300
height: 200
color: red
}
Why it show the whole screen red color.
I think it may be caused by window size. Is it right?
How does qquick scene graph display qml contents to screen?

Sounds like you are on Android or on some sort of embedded system? So probably
the reason is that you cannot have multiple windows: the whole application must
be full-screen by design.

That sounds like a nice solution.

On 192.168.0.18 I have stripped it right down to this this:

I think there's no such logic. QCommandLineParser will already see the

Hi Mark,
Starting 5.4 you can implement the skew yourself using the Matrix4x4 as input
to the Item.transform.
In 5.3 the way through public API would be to use a ShaderEffect or to
implement a custom item which returns a QSGTransformNode with a skew matrix
which has a textured node as child.

Hi Rainer,
It says this:
udp0 0 0.0.0.0:64540.0.0.0:*
If I stop my app, that disappears, if I change it to listen on
192.168.0.18 by changing this line:
udpSocRec-bind(QHostAddress(192.168.0.18), 6454);
I get this:

Ok, so your app can create the socket. Just to make sure: You _are_
running an event loop (Q{Core,}Application::exec())!?

Yes, I'm creating a standard Qt GUI using Qt Creator. With the same app,
I can send out packets over and over again. I've just got that bit
removed at the moment in an attempt to simplify things as much as possible.

You can't bind to port 123. That's a privileged port.

Would it be a nice idea to add a function to QCommandLineParser with

I had to go Android SDK for a project because the Qt support fell short.
Now I'm starting on the next project... How can I use the SDK app's intents in
the new app that I want to do in Qt? The new app expands on the old app's
features. So basically I want a Qt app to use the intents of the SDK

Before of anything else, thanks to anyone reading this message. I'm using
Qt 4.8.5 and QtCreator.
I use SQLite for data storage in an embedded system, and that is OK. There

of the QSqlQuery objects used on this program,

are there some changes between Qt5.2 and Qt5.3 regarding to signal and

Hi,
I am trying to build a version of Qt 5.2.1 with VS2010 that will use ANGLE for
Qt Quick 2.0.
Using these configure options

-confirm-license -release -no-c++11 -icu -openssl -angle -no-opengl
I get build errors
QSqlDatabase::close() closes the database backend connection but leaves
QtSql one intact, i.e. even after close() your QSqlDatabase object
occupies its slot in the [global] list of existing database objects. So
in order to let QSqlDatabase::removeDatabase() do its job you have to
destroy all
Hi,
I have 2 different displays (1 LCD and 1 HDMI) connected to my device. Is
it possible in Qt to direct the output of my video playback to a particular
