Super dumb question i feel defeated, Im using Qt5 with Qtgraph and I'm trying to get my results towards a text browser window I have displayed in my GUI. Is it possible or to even size a graph window in the GUI?

How do I use Qt as a dependency with custom OGL/Vk contexts

Hey everyone,

This must have already been asked but I couldn't find anything relevant to my situation (but maybe I missed it or searched the wrong words) so here is my situation :

I've been working on a toy engine (CODE HERE) for a while now and I feel like I need to finally add a GUI.

I've got years of professional experience with Qt, but I always used it as a framework for the projects I worked on. The situation here is a bit different since I already have a framework and would like to use Qt as sub modules/libs like how I currently use SDL to handle windows and various events.

Right now I manually create my OGL contexts using WGL/Win32 apis on Windows and GLX/X11 apis on Linux and I'm unsure how to handle it since I use multiple contexts accross my engine (a headless one for the Renderer, another one for occlusion queries and a final one for "swapchain" management).

I would be very grateful if someone could nudge me in the right direction because I don't really know how to connect dots here 😅

Material theme Qt5 to Qt6 port?

Has anybody got any experience of maintaining the look and feel of Material theme in Qt6, with how it used to look in Qt5? I.e. in 6 some of the button shapes changed to be more rounded for example.

If so, what approach did you take?

Im asking about QML if it makes any difference.

I had a thought to copy the qml/Material folder from the install directory, but not sure whether that would work without issue.

Qt and QML? whats the difference

Hey, I am new to c++ and I want to learn about how to build things in c++, I encountered QT and QML, but I am not able to get the whole picture of where qt, qml fits, and then there is other things like qtQuick, qt widgets. Could you mention the overview of what all qt as a framework consists of and like what all can be build with it with a analogy of, say, MERN or java + spring.

Examples projects links are down for websocket examples

I want to know how to handle the life time of a core application like a websocket client and see an example of how to do it by looking the official chat app example but the page is down, where I could find examples of how to use that module? my goal is to make it co exist with my client GUI that is made with glfw and ImGui and give it his own thread and find a way to share resource to pass the user input to the client and send a message to my test server, is there something that clarify this well?

Qt::GuiPrivate: target not found

So I'm trying to compile Krita from source, but I'm getting the error:

CMake Error at plugins/platforms/wayland/CMakeLists.txt:80 (target_link_libraries):
Target "kritaplatformpluginwayland" links to:

Qt::GuiPrivate

but the target was not found. Possible reasons include:

* There is a typo in the target name.
* A find_package call is missing for an IMPORTED target.
* An ALIAS target is missing.

I can't fix it. I've tried [steps on here](https://doc.qt.io/qt-6/qtguiprivate-module.html), but that doesn't fix it.

I don't know what libraries I'm missing. I *should* have everything, but I'm just getting this error.


System info:

Operating System: Arch Linux
KDE Plasma Version: 6.4.5
KDE Frameworks Version: 6.18.0
Qt Version: 6.10.0
Kernel Version: 6.17.1-2-cachyos (64-bit)
Graphics Platform: Wayland

I can send all the installed QT packages if needed.

QodeAssist v0.7.0 Released - Tool Calling

Tools demo

The most interesting thing about the latest update is that I added tool/function calling support, along with several basic tools for immediate use. In future versions, I'll be expanding them to cover more use cases. This will also allow us to release more frequently.

If you are interested, you can find out more about the new version or project here: https://github.com/Palm1r/QodeAssist/releases/tag/v0.7.0

QWidges 3rd party projects

In a previous thread, I mentioned that QWidgets's upstream development is "stalled". I mentioned that some 3rd parties are needed. Here is a list of projects I use/follow. If anyone has cool projects to share - do this.

Code I found online:

1. Flat tab widget, with cool animations: https://github.com/timschneeb/FlatTabWidget
2. Cool text editor, based on KTextEditor's highlighting: https://github.com/Wing-summer/WingCodeEdit
3. Animated slider: https://github.com/Wing-summer/WingCodeEdit
4. Progress indicator: https://github.com/epasveer/QProgressIndicator
5. Window title: https://github.com/stdware/qwindowkit
6. Widgets on window titles: https://github.com/antonypro/QGoodWindow
7. Adwaita widgets style: https://github.com/Qt-Widgets/adwaita-qt-style-qstyle (unmaintained fork?)
8. Image viewer widget: https://github.com/palacaze/image-viewer
9. Hex viewer widget: https://github.com/Dax89/QHexView
10. API to get your application notified about updates: https://github.com/alex-spataru/QSimpleUpdater

My own code:

1. Click Me Load MoreWidget, progress line (not bar!) - https://github.com/diegoiast/qtedit4/blob/main/src/widgets/Click Me Load MoreWidget.hpp
2. QLineEdit with history (global history, shared between all editors): https://github.com/diegoiast/qtedit4/blob/main/src/widgets/HistoryLineEdit.h
3. SplitTabwidget, like QTabWidget, but can also split the tabs horizontally, and move tabs between splits: https://github.com/diegoiast/qtedit4/blob/main/src/widgets/SplitTabWidget.h
4. Command palette widget, like SublimeText/VSCode: https://github.com/diegoiast/command-palette-widget
5. Creating config from code (might fork this into anotehr sub project): https://github.com/diegoiast/qmdilib/blob/main/demos/demo3/main3.cpp
6. Using freedesktop icon themes in your app, https://github.com/diegoiast/qtedit4/blob/main/cmake/icons-breeze.cmake (again, might fork this into a 3rd party project to reduce friction).

What am I looking for:

1. A bred crumb widget, for displaying files.
2. A good text editor widget (working on one, WingCodeEdit looks nice), with spelling check (optional?)
3. A terminal widget with windows support, MIT, LGPL.

How do I render a "raw" OpenGL Texture onto a QML Element ?

Hey everyone,

Here is the context: I have a toy engine that manages its own context. I would like to create a binding for Qt by writing the engine's render buffer onto a QML Element (so I can create multiple views of the same scene for instance).

I already found how to create a custom OpenGL context for a QQuickWindow and share lists with the Engine's context but I'm not sure how to connect the dots from here.

I found QSGTexture but I don't really understand how to use it. QRhi seems quite interesting too but I don't really understand how to pass the base window's OpenGL context to the QQuickRhiItem

Custom QOpenGLContext = "Cannot make QOpenGLContext current in a different thread"

Using a custom created QOpenGLContext triggers a fatal error inside QSGRenderThread on QQuickWindow::exposeEvent here. Ignoring this causes no issue and I could just set AA_DontCheckOpenGLContextThreadAffinity but I don't think I should.

Here is the basic code to set the custom OpenGL context when creating the QQuickWindow

Window::Window()
: context(new QOpenGLContext(this))
{
setGraphicsApi(QSGRendererInterface::OpenGL);
QASSERT(context->create());
setSurfaceType(QWindow::OpenGLSurface);
setGraphicsDevice(QQuickGraphicsDevice::fromOpenGLContext(context.get()));
}

I feel like I'm missing something but I don't really know what, I've never played around with QOpenGLContext
