Somehwere further down, the backtrace of the segfault should show you the line in your code that triggered the error.

thank you for your answers. :)

Its working now..after made the necessary changes... thanks Peppe @ //mainwindow.cpp QDialog *dlg = new QDialog; Ui::TestDlg ui; ui.setupUi(dlg); dlg->show(); @

Just as a test, have you tried using longer durations (say 250ms each) for each of the animations? Starting with larger numbers then reducing the duration down may give some insight to the operation of the sequential animation and how its interacting with the individual animations. There may be a floor value where things don't behave quite right because of the resolution of the system timers.

Yes, the GL code was wrong. It was clearing the buffer and it was assuming a different coordinate system. I removed the calls to glClear and glIdentity and changed the vertices.

[quote author="chernetsov0" date="1312173033"]Where do you put this action? It's not enough code to get the idea why tooltip is not popping. But maybe... [quote] Note that by default tooltips are only shown for widgets that are children of the active window. You can change this behavior by setting the attribute Qt::WA_AlwaysShowToolTips on the window, not on the widget with the tooltip. [/quote] [/quote] Sorry, tried setAttribute(Qt::WA_AlwaysShowToolTips); didn't work, and as for window, what do you mean? I normally just have to use set, with no window name, if anything, it'd be AdvancedTextEditor..

The usual way is to pass the parent widget in the constructor: @ // change your constructor declaration to public: mainWindow(QWidget *parent = 0); // change your constructor defintion to mainWindow::mainWindow(QWidget *parent) : QWidget(parent) { //.... } // and construct your object this way: cityDialogWindow = new mainWindow(this); @

Turns out I needed to make another call: @ _view->activateWindow(); _view->setFocus(); @

Eddy, animation framework is for creating animated GUI. I do not need that. I need the following. Say, I have a set of image files (for example, 100 of them) representing sequential frames. I want to make an animated file from those frames. There are a few standard options, including animated gif, AVI, mpg, etc. Can Qt help me in doing that? If Qt cannot help, then are there any other options which I could use to make my code to produce an animated file? Animated gif is one of the most widely used standards, and, by the way, Qt can read it. It would be nice, for example, if QMovie could save frames in animated gif, AVI or any other standard format. I just wonder maybe someone already tried to produce a file in a standard animated format?

That's correct, but you can't use "cin" command's because it only supports output and no input. That's the whole problem otherwise I wouldn't need to do it this way haha. Best regards

I don't think Qt has any such functionality. You'll have to use a different library to find the mouse position in a console app.

Good deal. Glad to help! Please be sure and edit the title of the thread to add [Solved]. Thanks!

Take the selected QStandardItem and call removeRows / removeColumns on it.

Ok it work. Thanks

bq. Do i need to tag this topic as closed or something? Yes, please could you edit your title and add [solved] in front of it. There are no other means at this moment, but the Trolls are implementing a way now.

Okay. But now it will copy library to my BIN folder (because it is set up globally (DESTDIR) ). Hmm...I must remake my QMAKE. But, anyway, thanks.

Hi Umen, I see that you started a new topic with your last question. If you consider this thread solved can you edit the title and add [solved] ? Thanks

Hi, I don't know QIdentityProxyModel. But as you only have a standard proxy model in 4.7, you have to have an index, that is created on this model and do your own mapping. You index function may never return an index from the source model directly. The function you mention can be called inside methods of the proxy model, e.g. for mapToSource, where it also works in 4.7.

Of course two calls to insertColumn will insert two different columns; use a foreach + appendRow.
