The Ubuntu maintainers changed the packaging of Qt's multimedia components, so it's different from other distros out there. I was never able to successfully get multimedia working on Ubuntu myself. But, see if this helps: http://qt-project.org/forums/viewthread/5348

I have been looking into this a little more, and I am now wondering if it is possible to do this :( Looking at QNetworkAccessFtpBackend::open() , it seems that this will only work through NoProxy or an FtpCachingProxy Also, I have looked into some of the proxy code, and in qnetworkproxy_win.cpp, in parseServerList, it looks like the only possible returns are HttpProxys, or Socks5Proxys Am I right in thinking that this is essentially not supported on windows? :(

Hi Thanks but that was a c&p error the .pro file does say TEMPLATE

Well, not quite true about the containers. QVector has a squeeze() method to free up unused memory.

You can't "link" it to destructor. Use separate slot for that, call "deleteLater":http://qt-project.org/doc/qt-4.8/qobject.html#deleteLater on window, and close it... Or reimplement "closeEvent":http://qt-project.org/doc/qt-4.8/qwidget.html#closeEvent to do needed cleanups.

Hi, I have another question. Is there any way to skip any particular test case/function while running the test using QTest::qExec(). The scenario is that i have listed the test functions in a treeView with checkbox as a QStandardItem, So foreach testClass the associated testFunctions are listed. Now the requirement is to test only those cases/functions that are checked and the other's should be skipped. I have tried @testCmd<<" " << QString("%1").arg(childItem->text())<<"-xml" <<"-o" <<QString("UnitTest_Results/%1_log.xml").arg(className); QTest::qExec(plugin->testList().at(pRow),testCmd);@ this generates an xml output but the xml.file is overwritten for each test function and at the end displays the result of the last checked item. Thanks.

Fantastic!!! That worked alexisdm! Thanks so much for the tip!

Thanks for your reply! I changed the amount of memory used by the graphic card and now it works.

After struggling of several hours, I find out that my scaling methods has some bugs, sorry to bother you all.

I understand now :) You want to select a set of items in a GraphicsView by pressing and moving the mouse, simultaneously. I think the solution is like when you draw a line by pressing/moving the mouse. You can see the diagramscene example, to get an idea. In the other hand I know a libre soft that uses this trick. You can get its source here [Umbrello UML Modeller]http://uml.sourceforge.net/ Good luck !

Same issue with demo compilations windows in mingw compilation. Checked syntax's and declarations right, gives an qrc_xyz.cpp "file not found error" when compiling xyz.qrc in the same directory for .png files.

As always, install the translator using QApplication::installTranslator(); Of course, when you create your context menu, you'll have to use tr(), like myMenu->addAction(tr("Copy")) instead of just myMenu->addAction("Copy"), in order to make them translatable. And then you will also have to translate the new strings in your TS/QM file. And: Don't forget to re-translate after installing a new translator!

Hi, tucnak. Thanks for your help. My QSS removes all the arrows from the scrollbar with setting height or width to zero and show only the background and the handle. But I could not customize the handle itself, since background-image could not work. And it is possible to stylesheet own customized Widget if you overload the paintEvent method to draw the QStyle::PE_Widget. Anyway, I have never made my own style and now I'll give it a try.

Thanks a lot jazzycamel.. :-)

I solved the problem @ graph_pixmap_->setPixmap(QPixmap::fromImage(image)); graph_scene_->setSceneRect(image.rect()); graph_view_->resetMatrix(); //call this @ because fitInView would change the matrix, so I should reset it every time I open the image, thanks

I just find the answer, size() and viewport()->size() whatevever, I need to find out the different of these size.Thanks
