[Interest] Use QMetaEnum::keyCount() to initialise array

Is it possible to use QMetaEnum::keyCount() to initialise an array? Something like: const QMetaEnum metaEnum = QMetaEnum::fromType(); int MyArray[metaEnum.keyCount()]; It seems like Q_ENUM declares functions with Q_DECL_CONSTEXPR in C++11 but I can't figure out how to get this to work.

Re: [Interest] QtOpcUa 5.12.0 build

Hi, As Thiago said, the config.log should reveal some more insights. Also for 5.12 we moved to a later version of Open62541 as there were files being moved around. Please note, that the very latest open62541 again changed the structure of the include directory, a patch for that is pending.

Yes QApplication destructor is invoked last..Does it makes sense to use deleteLater() in the widget destructors instead of existing delete if it could be cleaned up as part of qApp-quit()? On Wed, 19 Dec, 2018, 12:03 Konstantin Shegunov On Tue, Dec 18, 2018 at 8:25 AM Ramakanth Kesireddy >

Re: [Interest] QFile subclass that does HFS compression?

The easiest way is probably a QIODevice wrapper implementing the HFS compression. Although I'm honestly surprised someone designed an interface like this. "Neither smart nor good" might be a ML-friendly way of putting it. Cheers, Marian Am 19.12.18 um 11:06 schrieb René J. V. Bertin: > Thiago

Re: [Interest] Qt3D How to draw 2D-Text always facing the Camera

The number of Text2D elements is not known in advance and may differ. It's a simulation environment, where some textual information is added to a fairly high number of elements. To avoid the data management for different kinds of entities my first idea was to create a specialized Text2d  entity

Hi Oleg, Could you specify the screen resolutions of your phones as well please? (I suspect they are lower than the tablet) From what you are describing (moving further/nearer/multisampling) it seems you are having fragment shader performance limitations. You didn't specify what the benchmarks

Re: [Interest] Qt3D How to draw 2D-Text always facing the Camera

Then I would stay with the first solution I proposed, it will be more flexible in your case: regular text2dentity with custom frame graph branch and custom camera. There is just one thing to be aware about the text2dentity, the entity doesn't do the rendering itself: it contains another
