Re: [Interest] logrotating qDebug
Hi Thiago,
i am not sure i understand your response... if the problem was a file
offest would not affect all the files and all the rotations? (there are any
processes of the same app that have their outputs redirected to different
files that are rotated)
But only some of them show this behaviour while others are rotated as i
would like.

You forgot the restarting of your application.
The file looks binary because of that copytruncate at the end. When
logrotate
runs, it will truncate the output file to zero size. But since you didn't
restart the application, it will continue writing from the exact byte
offset as
it had been before. That means the beginning of the file is composed of NUL
bytes. Hence, binary.

[Interest] iOS Guidlines and QML
Hi, i have a question to the Apple App Store Guidelines in conjunction with QML: I plan to write an iOS app that downloads a remote QML file which is the main part of the app from a remote webserver. As i read the Guidlines i stumbled upon the following rule which would interfer with that: 2.7 Apps that download code in any way or form will be rejected But i know that there are already approved QML apps (submarine example) in the App Store. So actually these must have interfered with this: 2.8 Apps that install or launch other executable code will be rejected Since QML can contain JavaScript i would expect that it is also considered as executable code? ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] ssl socket still encrypted after disconnect
Hi Thiago,
thanks for the reply, i'll file up a bug and try to create a small snippet.
However, for the time being, is there an API to reset/set the SslMode to
UnencryptedMode? or should i refactor my code to delete the SslSocket and
create it from scratch? or.. any other ideas?

What i gather is that the startClientEncryption() fails because of the

Can you post a small sample of your code?
Though I think I can see the problem. QSslSocket::setSocketDescriptor does
not
call d-init(), like connectToHost{,Encrypted} do.
Please report this as a bug. The fix looks simple, but it needs testing.

Hi,

thank you very much!
You're welcome.
(I have read your 5 parts article:
http://www.kdab.com/opengl-in-qt-5-1-part-1/
and tried the terrain_tessellation project
http://www.kdab.com/~sean/terrain_tessellation.zip [awesome])
I want to use the QGLWidget, because I get 'artefacts' if
I use QPainter's drawText in QWindow and it is possible to
add QGLWidget as central widget in QMainWindow.
With the QWindow I can only render something (I think) and
found no solution to add it to something or to use buttons, sliders etc.
Before I got your answer, I found a solution:
http://qt-project.org/wiki/How_to_use_OpenGL_Core_Profile_with_Qt
https://svn.theharmers.co.uk/svn/codes/public/opengl/trunk/07-core-profile/
and
http://qt-project.org/forums/viewthread/16041/#90717
So, if I want to use the 'glTextureView' (Core since version 4.3,
http://www.opengl.org/wiki/GLAPI/glTextureView) in GLWidget:
...
voidGLWidget::initializeGL(void)
{
...
typedefvoid(APIENTRY*_glTextureView)(GLuint,GLenum,GLuint,GLenum,GLuint,GLui
nt,GLuint,GLuint);
_glTextureViewglTextureView;
glTextureView=(_glTextureView)context()-getProcAddress(glTextureView);
if(glTextureView!=NULL)
{
qDebug()Q_FUNC_INFOglTextureView!=NULL;
}
...
I have not used the function, but this code works for me.
In all seriousness, unless you actually enjoy resolving function pointers I
would just use QOpenGLFunctions_4_3_Core. It will make your life much easier.
As an aside if you are interested in OpenGL texturing, please do try out
QOpenGLTexture which is new for the upcoming Qt 5.2:
http://doc-snapshot.qt-project.org/qt5-stable/qopengltexture.html
If I use your solution in the 'voidGLWidget::initializeGL(void)'
function from the
https://svn.theharmers.co.uk/svn/codes/public/opengl/trunk/07-core-profile/
example and add it as central widget in a QMainWindow, it will not work
at 'm_context-create();'.
I've not tested any of that old code with Qt5. Instead prefer QGLWidget +
QOpenGLFunctions_4_3_Core which should work perfectly fine.
So, the idea is, to have a render surface in the center of a main window and
have dock widgets around to manipulate the render surface. I don't want to
render buttons, check boxes and sliders (etc.). I want to use what the Qt
library has.
(Ok, later perhaps in a game development, it looks like better ... :-) )
It would be nice (a wish) to have more documentation and examples about
OGL with Qt.
More clarity about additional libraries, which are not necessary anymore
(i.e. glew).
I agree. Patches welcome. I'm very busy at present improving support for
textures and other areas which we will need for a new Qt3D.
Btw. there is no description for 'QGLContext::getProcAddress' in the
documentation.
I don't understand:
...
QGLFormatglFormat;
glFormat.setVersion(1, 0);
...
The documentation is not enough for me. I can set the version 1.0, but
the functions
above 1.0 works.
Check which OpenGL context version was actually created. I suspect you
actually obtain a 1.5 context or maybe even 2.1 of which 1.0 is a subset.

Sean

Re: [Interest] QImage, multithreaded app.
Hi, as Thiago already stated there are no limitations using QImages inside multithreaded apps. Why do I know this? Because I'm developing and using an industrial image processing framework with massively multithreaded image processing based on QThread and QImage. So I fear that you have some serious issues inside your thread handling - often devs mix up with the gui thread (main event loop) and wonder about the app getting an unpredictable behaviour when other QThreads interact with widgets (objects inside the GUI thread). Be very very careful with data handling between GUI and other threads! And don't forget: Accessing GUI objects from outside threads can cause severe errors. ciao, Chris___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

[Interest] [QSS] Treeview headache
Hi there,
I'm stumbling on a very frustrating problem here with QSS.
My problem in a nutshell: I want to add a highlight on hover effect on
QAbstractItemView-based classes.
So I wrote that in the app's qss file:
QAbstractItemView::item:hover:!selected {
background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0
#e7effd, stop: 1 #cbdaf1);
}
So far so good, now my items have a nice blue-ish overlay when the mouse
hovers over them.
Except for the branches in a tree view, which are a separate subcontrol !
So I added that:
QTreeView::branch:hover:!selected {
background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0
#e7effd, stop: 1 #cbdaf1);
}
Now I have the overlay, but the branches themselves are not drawn
anymore... Shaaame.
Going on, I saw in Qt doc that example of branch customization with images
(second part of
http://qt-project.org/doc/qt-4.8/stylesheet-examples.html#customizing-qtreeview)
, and I thought « great, that's exactly what I need! » It almost worked,
but if some of the branches of the tree have different heights then the
images are scaled and it's ugly. Saaad.
So I tinkered with the border-image property, tried various combinations,
and so far, not so good. I just can't get it right.
If anyone has any thoughts to share about my problems (eg why the original
branches drawing are being wiped out by setting some qss, if there is a
workaround, etc.) I would be more than happy to here them :)
Best,
Clément

least.
Problem:
QSettings fails to return specific key value (Common AppData) when read other
keys at the same level just fine.
Key exists and verified with regedit.
Test case is below:
#include QApplication
#include QSettings
#include QDebug
void ddd2();
int main(int argc, char *argv[])
{
// execute test and return
QApplication a(argc, argv);
ddd2();
return 0;
}
void ddd2()
{
QSettings
reg(HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Shell
Folders,
QSettings::NativeFormat);
QString key;
QString val;
key = QString(Common AppData);
val = QString ( reg.value(key).toString());
qDebug() key: key value: val;
key = QString(Common Desktop);
val = QString ( reg.value(key).toString());
qDebug() key: key value: val;
key = QString(Common Documents);
val = QString ( reg.value(key).toString());
qDebug() key: key value: val;
}
Output:
key: Common AppData value:
key: Common Desktop value: C:\Users\Public\Desktop
key: Common Documents value: C:\Users\Public\Documents
Expected
* WinXP: c:\Documents and Settings\All Users\Application Data
* WinV/7/8: c:\ProgramData

Alex
