General and Desktop

@canid said in Under windows7, call QApplication::exit(0) to exit the program. Why is the APPCRASH error reported?: From which window can I get this information? Dependency Walker is an extra tool available in the net. And searching for openssl libs can be done with the explorer. The PATH can als be inspected with Windows tools.

Hi If you open the SVG in say inkscape and change its page size (ViewBox) does it then work as expected in your app ? Im not sure i understand what the goal since QSvgRenderer::setViewBox() did change the rendered size for me with QIcon so are we looking for something else ?

-> OpenSSL Check the Maintenance Tool. IIRC, you can install it from there.

Hi and welcome to the forums QTCreator and Qt Design Studio are different products and hence both project structure and and the menus are not the same. As far as I know, you can only do it from code in Creator https://doc.qt.io/qt-5/qml-qtquick-fontloader.html

Hi And just to have both ways. I mostly do all in Designer and love the promotion feature allowing me to design with a custom widget. I use the dynamic property system to allow Design time customization for my custom widgets and the only code i write is for the dynamic parts. (loading data ) and for the parts that Designer do not support. Also, for a team, using UI files makes it easier for the non-UX developers to add a button and such without having to know exactly how it works as it's easy to drag a widget from left to someplace on the form/in the layout. Finding the same spot in many lines of code is not that easy. Also, designing complex layout using a Designer is good for leaning as you see the result at once. From code, you have to run to see what you got. That said, writing layouts in code, gives a firm understanding of how they work. For your case. Qt does not have anchoring as such with Widgets so unless one of the layouts suits the case, then manually setting the pixmap pos in resizeEvent is also an option.

Hi, Yes this is possible. Use the currentChange signal of your first view to trigger whatever update is needed for your second view.

Ok thanks!.. i will check both answers..

@mrjj Yep that makes sense that it was what was happening, thank you very much for the help!

Oh, my fault. My eventloop is dead lock. No need to register pointer, in fact.

@Pl45m4 yes, i try many apis in Q3DSurface, such as Q3DLight, Q3DCamera,scene and have no use. Anyway, thank you!

Because this macro is using QObject functionality.

@SGaist Perfect. That is what I was looking for. Thank you very much.

@SGaist Yes, much better, thanks! I should have had that intution on visibility -- live and learn. Marking as resolved. -Phil void MainWindow::showEvent(QShowEvent *event) { QMainWindow::showEvent(event); QModelIndex index = table->model()->index(50, 0); table->scrollTo(index, QAbstractItemView::PositionAtBottom); } [image: 35d002e4-5d7a-495c-8d55-ba14d8de177b.png] )

Thank you so much for the help, I pass the QLineEdit as a parameter in my constructor and work as I expected =D

I'd say you likely have found a bug. I'd recommend taking a look at the bug report system to see if there's something related to it there. If not, please open a new report providing your example project there (please include a .pro file so it can be directly compiled).

Hi emit rarely fails so i would check bool result = connect(a, SIGNAL(textChanged(QString)),ui->lb_ax, SLOT(setText(QString))); qDebug()<<"conn;" << result; Since you do MyOpenGLWidget *a = new MyOpenGLWidget; connect(a, SIGNAL(textChanged(QString)),ui->lb_ax, SLOT(setText(QString))); a->someFunctionThatChangesText(""); It should be the MyOpenGLWidget you think it is, which else is a classic error. Last thing that can be wrong, it that you might somehow block the event loop as you inserted QApplication::processEvents(); QWidget::repaint(); which should not be needed.
