@Cute3d, yes, it finally works. Idk what was wrong. Example project:https://github.com/Nonmant/Qt3DExtras-QText2DEntity-Example
And due to god-knows-what reasons it doesn't work in debug mode. Hope, that project can help someone.

Ok, it sounds like a bug then.
Good if you open ticket.
Make sure to include a small complete working example they can use
to reproduce it.

I have add C:\mysql\mysql-5.7.21-winx64\lib into path variable. but don't work!

Thank you all, the issue is solved.

Actually, since the base class already has a virtual destructor you can just remove the destructor of your derived altogether

You could set default sorting column to -1 by QHeaderView::setSortIndicator like this

yourTableView->horizontalHeader()->setSortIndicator(-1, Qt::AscendingOrder);

before running

yourTableView->setSortingEnabled(true);

because QTableView::setSortingEnabled uses QHeaderView::sortIndicatorOrder and QHeaderView::sortIndicatorSection to identify by which column should model be sorted.

Note that documentation of QHeaderView::setSortIndicator tells that not all models support setting sort column to -1 and may even crash in this case.

@kshegunov yes that is exactly what I was wondering. I was not sure if plugins can be loaded into other C++ plugins or not. I will give this a shot.

@SGaist good point about creating a library. I think isolating the communication API into a dynamic library would be an even better solution as you suggested. I will have to do some refactoring.

Thank you both for sharing the quick and helpful response!

Yes, you're right. Thanks.

The answer in stackoverflow is correct.

Is there no other way to get notified when an Edit begins?

just declare and emit your custom signal in the delegate subclass

Remember 1 model can service multiple views so, normally, the model should not depend on the state of the view or delegate

Hi and welcome to devnet,

That's a question you should rather bring to the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.

@moldovan.catalin You can create symbolic link in /opt/vc/lib pointing to these libraries but having old names.

Hi! Have you seen the Qt 3D: Planets QML Example?

@romsharkov said in Incorrect Font Metrics:

@raven-worx Didn't know about those methods, just tested it, for the lower case letter "g":
QFontMetricsF::leftBearing() returns: -4.17188
QFontMetricsF::rightBearing() returns: 0.6875
But even if I add the (negated) leftBearing to the total text width it still doesn't cover the tail entirely, so what's wrong here?

are you sure?!
Those values seem to be correct / make sense according to your posted screens.

Make sure that you add the absolute value (qAbs() for example). Also keep in mind that those values are only correct for the given font-size and that you can't add negative values to a image width.
I guess you are just doing incorrect calculations. Can you show the code of the calculation?

@Naveen_AC
I guess that Qt Quick Compiler is available for commercial license only.
I don't know if this is the case.

Qt 5.9 also comes with a brand new QML caching infrastructure, offering similar benefits to our users — just like the commercially available Qt Quick Compiler, but in a much more transparent way.

I hope that Qt developers solve this issue.

Hi,

See the documentation of bufferSize, you may not get what you requested because setting e.g. a too small buffer size might trigger overflow problem.

@SGaist

Thanks. I will try it.

@Mahesh-Kumar-Kodanda said in QT 5.9 for i.MX6Q and Integrity RTOS build error - unrecognised command line option »-std=c++11«:

cross compile tool chain

For which device? You already use one- why do you ask me to provide one? A cross compile tool chain is not specific to Qt or any other framework/library but to a device.

I have reported this issue on the Qt bug tracker.
