From QRHI :

Each QRhi instance is backed by a backend for a specific graphics API. The selection of the backend is a run time choice and is up to the application or library that creates the QRhi instance.

See also the example:

#if QT_CONFIG(vulkan) QVulkanInstance inst; #endif // ... // ... // ... // ... #elif QT_CONFIG(vulkan) inst.setExtensions(QRhiVulkanInitParams::preferredInstanceExtensions()); if (inst.create()) { QRhiVulkanInitParams params; params.inst = &inst; rhi.reset(QRhi::create(QRhi::Vulkan, &params)); } else { qFatal("Failed to create Vulkan instance"); } #endif if (rhi) qDebug() << rhi->backendName() << rhi->driverInfo(); else qFatal("Failed to initialize RHI");

So it's up to YOU (the developer) to chose a backend (or leave it dynamic)...
If you force the use of Vulkan and further only use the Vulkan API, you program/code only works with Vulkan

and like @SGaist said above... if no Vulkan SDK or libs are found or the system is incompatible with Vulkan at all, your program won't work (you need to handle that also... for example like shown in my example via defines and error handling)

Hi,

Well, the undo framework allows you to go back and forth in a controlled fashion. You can have multiple different commands based on your various workflows that can be handled by a single stack. There's a model that you can visualize while developing the feature.

@StudentScripter great !

Then please mark the model as solved using the "Topic Tools" button or the dotted menu beside the answer you deem correct so that other forum users may know a solution has been found :-)

OP's Ubuntu should support stat file for Birth. See e.g. How to Find Out When a File Was Created in Linux for a recent discussion of the issues.

@Pl45m4 Worked like a charm, thank you very much. :)

@ECEC said in Binding C++ objects in std::vector to QML components:

@jeremy_k

I'm not too sure what benefit you are suggesting QStandardItemModel would have over subclassing QAbstractListModel.

The only advantage is less stuff to write and maintain. I count 6 lines of code above, including headers, specific to the standard item model.

In Client Side:

openssl s_client -connect 127.0.0.1:7000

You can see the client disconnected while the dialog is in open

@Vivek_A
This question seems to have nothing at all to do with Qt, does it? So shouldn't you ask at a mongodb forum?
