By the way, if you will hit some limit (maybe an embedded device) you can store in a ini file names or paths to reach and load other specific ini files. But as stated in this thread, you will never hit the ini file size unles you use it in an improper way (e.g., storing large strings as user data).

I get the same problem but I can't find the solution ? please tell me how you resolved it ? the ts file doesn't generated absolutely @ Project MESSAGE: C:/Qt/4.7.4/mkspecs/features/default_post.prf(5):Function 'system' is not implemented C:/Qt/4.7.4/mkspecs/features/debug_and_release.prf(66):Function 'eval' is not implemented C:/Qt/4.7.4/mkspecs/features/debug_and_release.prf(69):Function 'eval' is not implemented C:/Qt/4.7.4/mkspecs/features/debug_and_release.prf(72):Function 'eval' is not implemented C:/Qt/4.7.4/mkspecs/features/debug_and_release.prf(75):Function 'eval' is not implemented C:/Qt/4.7.4/mkspecs/features/debug_and_release.prf(78):Function 'eval' is not implemented C:/Qt/4.7.4/mkspecs/features/debug_and_release.prf(80):Function 'eval' is not implemented C:/Qt/4.7.4/mkspecs/features/debug_and_release.prf(82):Function 'eval' is not implemented C:/Qt/4.7.4/mkspecs/features/debug_and_release.prf(84):Function 'eval' is not implemented This application has requested the Runtime to terminate it in an unusual way.

Actually, in principle UDP is much more suitable for this application. You don't want to halt a whole video stream just because you missed a single frame. However, it does take some work to get it to work... On a sidenote: it looks like you want to send an uncompressed stream of images. If we add network overhead to your image size, you are trying to send about 1MB per frame. To make that into streaming video, you end up with about 24MB/s raw network speed. I hope you realize you need a Gbit network to get that throughput? 100Mbit is not enough for such a data rate.

Nice, thanks!

Thanks! I got it to work! I knew there was something that wasn't right. I'll remember that checkable problem.

A bare-bones example snippet. @void TestOGLWidget::paintEvent(QPaintEvent* event) { QPainter p; p.begin(this); p.beginNativePainting(); makeCurrent(); glClearColor( 0, 0, 0.1f, 0.0 ); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glColor3f(.9f, .7f, .7f); glBegin(GL_QUADS); glVertex2i(5, 200); glVertex2i(200, 200); glVertex2i(200, 5); glVertex2i(5, 5); glEnd(); p.drawText(10, 30, "Test 111111"); p.endNativePainting(); p.end(); }@ TestOGLWidget inherits from QGLWidget. Over ssh p.drawText(10, 30, "Test 111111"); doesn't render and we get the following warnings : bq.

[quote author="Gerolf" date="1322777479"]why don't you use a table view and a delegate for the editing?[/quote] Oooh great Gerolf, I've never thought about it ! Thanks for your answer ! But for a better explanation, the last block is not implemented, I replace the loop : @/* Loop for Tx Display Area Layout */ for(int indexLayout = 0; indexLayout < TX_DISPLAY_NUMBER; indexLayout++){ tx_ScrollAreaLayout->addWidget(tx_Label[indexLayout] , indexLayout+1 , 0, Qt::AlignLeft); tx_ScrollAreaLayout->addWidget(tx_Channel[indexLayout] , indexLayout+1 , 1, Qt::AlignLeft); tx_ScrollAreaLayout->addWidget(tx_SDI[indexLayout] , indexLayout+1 , 2, Qt::AlignLeft); tx_ScrollAreaLayout->addWidget(tx_Data[indexLayout] , indexLayout+1 , 3, Qt::AlignLeft); tx_ScrollAreaLayout->addWidget(tx_SSM[indexLayout] , indexLayout+1 , 4, Qt::AlignLeft); tx_ScrollAreaLayout->addWidget(tx_Parity[indexLayout] , indexLayout+1 , 5, Qt::AlignLeft); tx_ScrollAreaLayout->addWidget(tx_Status[indexLayout] , indexLayout+1 , 6, Qt::AlignLeft); }@ by the loop : @for(int indexLayout = 0; indexLayout < TX_DISPLAY_NUMBER; indexLayout++){ txDisplayArea->setWidget(tx_Label[indexLayout]); txDisplayArea->setWidget(tx_Channel[indexLayout]); txDisplayArea->setWidget(tx_SDI[indexLayout]); txDisplayArea->setWidget(tx_Data[indexLayout]); txDisplayArea->setWidget(tx_SSM[indexLayout]); txDisplayArea->setWidget(tx_Parity[indexLayout]); txDisplayArea->setWidget(tx_Status[indexLayout]); }@ but each loop doesn't make what I want : set the scroll bar So I'll try with QTableView, I think this is the best way to realize what I want! Thanks a lot !

Did you try the QGraphicsItem::ItemIgnoresTransformations flag?

QRegExp is indeed rather limited. I don't know if this issue you run into is a (known) limitation (can't find it in de docs with a quick scan). However, I do know that this issue will be addressed in Qt 5, as the regexp engine will be replaced by something a bit more standard, featured and performant.

The fact that Qt can fill your polygon, does not mean that it knows how many pixels are red. Filling doesn't work that way. You could of course paint your polygon into a QImage, and can the image line by line to count the number of colored pixels. Not very efficient, but perhaps enough for your goals?

@ db.setDatabaseName("data.sqlite"); @ searches in the current working directory, if that's wrong, give an absolute path as the argument.

Bascially, there's a QStackedLayout (m_modesStack if I recall correctly) which holds the widgets corresponding to the selected icon (aka mode).

You're welcome. Glad to know it works now. You might add "[Solved]" to the topic (just hit the edit button of the very first post in the thread and adjust the title).

If it is a pure in parameter, you can try: @ void fooSub(LPSTSTR X); // this is our function :-) foo() { QString text; if(sizeof(TCHAR) == 1) fooSub((LPCSTR)text.toLocal8Bit().constData()); // here you have to check, how to convert, you could also use utf8(), ... else fooSub((LPCWSTR)text.utf16()); } @

[quote author="Ashish Mittal" date="1322728419"]Hi, Morever, if I will use getDC() function of QWidet to pass DC to some other app of QWidet to draw on widget, can we use same code for Linux also, since it is wriiten like this function is not portable. If not then what could be the other alternative.? [/quote] If you use stuff like getDC, winID etc, the code is not portable. This is platform specific stuff and must be implemented for each platform using #if
