General and Desktop

The "release notes":http://qt.nokia.com/products/changes/changes-4.8.1 state: bq. Add support for XCode 4 into qmake [QTBUG-17247]

3 licences are available (more, actually, but let's ignore the rest). Just download the sources, and check for LICENCE files. You can also check any source file. It mentions LGPL 2.1, GPL 3 and "other usage" (meaning: commercial license).

Please practise some patience. It is not acceptable to kick your topic within a reasonable time period. At least allow a few days for people to answer, a week is generally accepted as a time when it is acceptable to kick your topic like this. On using a video as a background: It is certainly not supported using style sheets. If you can do it at all, it will have to be done manually, by placing your widgets over a video view. I have no idea how that will perform, or what kind of visual glitches you can expect.

Thanks Jake it worked for me...

The operating system is calling my c function. Very often. I DO NOT want the thread pool to delete any threads when the work is finished. I don't see how QMutex or QWaitCondition can be used for blocking until threads have completed the current work assigned to them for the current C_Callback)function call. if you think this can be done, I'd like to see some code to demonstrate this. The devil is in the details...

if you still have that problem SeedOfLife.i just added the .dlls for the Qt modules i was using in my application and in addition i also added the compiler specific dll i was using MingGw so i include the dll that d2uriel has mentionde in his post above.sorry for late reply

And then just delete the item.

The spacing issue comes from HTML <p> margin style, which if not set, is defaulted to some value. However, I advice you to make all your texts as HTML templates, since they are static, they will only have color template for highlighting. I took my scale.txt file and duplicated it's text twice - no spacing issue with the same executable.

You connect the signal finished from video player to your slot finished, load image to QPixmap and add it to you graphics view or whatever you have. "Signals and slots":http://doc.qt.nokia.com/4.7-snapshot/signalsandslots.html And take a look "here":http://qt-project.org/forums/viewthread/13613/, how to display QPixmap on QGraphicsScene Regards, Jake

Yes it seems that the keyPressEvent() function is blocked when dragging an item from the list/table. But, if you press "escape(Esc)" on the keyboard the dragging of item is cancelled ,still keyPressEvent is not fired.

@sruthihsr: Please can you tell where do you insert XMapRaised ?

well, why don't you check the source code to see how it is implemented?

Thanks RaubTieR. Works great.

ok thanks all for your helps.

Env: Qt 4.7, OS X 10.6.8, 8 cores, 8 gb, 3 GHz, Macpro, three PCI display cards, six monitors. Behavior is the same on my laptop, though, which is pretty different other than OS. I have: @ CPlotter::CPlotter(QWidget *parent) : QFrame(parent) { setMinimumHeight(384); setMinimumWidth(1280); QSizePolicy policy( QSizePolicy::Expanding, QSizePolicy::MinimumExpanding ); setSizePolicy(policy); setMinimumHeight(384); setMinimumWidth(1280); etc... @ ...and... @ class CPlotter : public QFrame { Q_OBJECT public: explicit CPlotter(QWidget *parent = 0); ~CPlotter(); ...etc @

replace the line <string>TextLabel</string> with <cstring>TextLabel</cstring>

Hi, After some years of research, i think i've found the problem. The variable that contains a crazy value is initialized in the first thread. And, this variable is used in the second thread. When the program starts, it do that : @lesLiensEtDebits.Traiter(index); lesObs.Traiter(TraitementObs::DROPSETCHARGES);@ NOTE : Traiter( ... ) is a method which start the thread with start(). I put one cout where the 1st thread begin, and another when the 2nd one begin too. When the program starts successfully, there is "one" and "two" at the output. When the program CRASHS, there is "two" and "one" !! IT'S CRAZY ! The second thread began before the first one !! So, i trying to do that correctly, so something like @lesLiensEtDebits.traiter(index); connect(&lesLiensEtDebits, SIGNAL(finished()), &lesObs, SLOT(Traiter(TraitementObs::DROPSETCHARGES)));@ But the program said me an error , it don't find this slot.. The slot is @ void Traiter(TraitementObs::type _choix );@ So i want to pass a parameter in the slot, i don't know if we can do that. Any idea for how to start the 2nd thread AFTER the 1st one finished ? Thanks for your help,
