Hi,
I am finishing an embedded system, using Linux and Qt as the base of the
application that manages the system, and as a manager to a SQLite database
for this application. As it will be using a flash SATA module, I would not
like to do many and frequent write operations to it.
So, I would

Hi,
I have been experiencing a strange behavior with QStringList and the order of
execution of takeFirst.
The following code:
QString line = file.readLine(); // line contains 46 71\n
QStringList lineData = line.split(); // lineData contains (46, 71\n)
qDebug() lineData.takeFirst()

The problem is not takeFirst.

Hi, all!
I'm trying to run my app on the omap4 module (it's variscite var-som-om44
with the ubuntu 12.04 on it). I cross-compiled qt5 (tryed 5.0.2, 5.1.0,
5.2.0) and cross-compiled my app. It builds well, but when I tried to run
it on the device I got an error: http://pastebin.com/GYHPE34P

Hi
I am developing a library and in Qt Tradition I want to use the d_ptr pattern.
I have no previous experience of using this pattern and have a simple example
working but wanted to check that my implementation is correct.
To that end I have set out my classes below and would be grateful if

Good morning,

I’ve partitioned the app window into a status bar and a display area. The

Hi all,
I would like to embed a Google Map using Native SDK on Android. Now I am
able to construct the Map using Java code. However, it has problem to
interact with QML.
The Google Map library (part of Google Play Services) render its content on
an android.view.View object. As QML do not support
1) put your 'd_ptr' into a smart pointer of some kind (usually
QScopedPointer), your example leaks memory;
2) placing 'q_ptr' in the public section doesn't make much sense because
it's supposed to be used only by the DisplayWidgetPrivate instance to
access its owner (DisplayWidget doesn't need any

Right, but:
1) classes derived from DisplayWidget may want to derive their *Private
counterparts from DisplayWidgetPrivate — in this case private section
will make DisplayWidgetPrivate's internals accessible only to this class
itself and its friend DisplayWidget;
2) since not all compilers support

Ok, but if your 'private' class is designed to be derived from, then I
guess it was not all that private after all. It is more like it is to be
protected instead of private. If the class really is private (for
instance by not using a displaywidget_p.h for declaring it, but by just
Hello all,
For a customer specific application we are forced to use only C++ code without
QML.
Up to here there are no problems, except that in this new software, we need
massive use of listview (finger-scrollable, with text and image objects, smooth
moving).
So, the QML Listview is exactly
Yes, I meant the private subclassing in a way like the one used by Qt
where it's used to both hide internals from the outer world and reduce
memory overhead by sharing one 'd_ptr' field between many classes.
But no, 'd_ptr' must be private to prevent classes derived from
DisplayWidget from

Hello Alan,
thank you.
The customer don't want QML because for some strange reason he don't want to
use it. I don't know much more, anyway I have to adapt..
And of course we cannot force him to use QML.
I've saw your example but seems that is only for qt5, we are currently using

Probably because binary representation is more space-efficient.
