I have installed QT version 5. I have try use QtWebEngine but it is not recognized. Does anyone know how to use QtWebEngine? But anyway you installed Qt for VS, so why do you want to use it with mingw32?? Obviously thats not possible. So, i have installe in qt only msvc 32bit but in the kit is disabled.
Excuse me, I'm a newbie, but do not the modules in the kit serve only to compile based on where the programs will be run?
When I write the program it should not affect, or am I wrong? What raven-worx meant is that you can't mix and match compilers on Windows. For Visual Studio it goes even further, the different versions of VS are not compatible one with the other except for VS which is backward compatible with VS SGaist said in QtWebEngine :.
So does it means that if you install VS, you are able to compile with msvc prebuilt component? I have installed VS and QT 5. But wen buil the program I have error in :.
SGaist Good Morning, the cod of main is this :. SGaist Arghh. You will find lots of this specific question and its solutions. JonB ok thanks. I lunch with debug and i have this error.
The same project run in x64bit with 5. SGaist Ok, I'm stupid.The Qt WebEngine module provides a web browser engine that makes it easy to embed content from the World Wide Web into your Qt application on platforms that do not have a native web engine.
It is a library that must be shipped with the application if the Qt libraries are bundled into the application. A web engine view is the main widget component of the Qt WebEngine module. It can be used in various applications to load web content. Within a view, a web engine page holds a main frame that is responsible for web content, the history of navigated links, and actions.
The view and page are quite similar, as they provide a set of common functions. All pages belong to a web engine profile that contains shared settingsscriptsand cookies. Profiles can be used to isolate pages from each other. A typical use case is a dedicated profile for a private browsing mode, where no information is permanently saved.
The supported page functionality is integrated into the web engine view.
Chromium provides its own network and painting engines and is developed tightly together with its dependent modules. Note: Qt WebEngine is based on Chromium, but does not contain or use any services or add-ons that might be part of the Chrome browser that is built and delivered by Google. You can find more detailed information about the differences between Chromium and Chrome in this overview that is part of the documentation in the Chromium Project upstream source tree. This version of Qt WebEngine is based on Chromium version This mitigates security issues and isolates crashes caused by specific content.
For a widget based application, the web engine is automatically initialized, unless it is placed in a plugin.
In that case, it must be initialized in the application main source file by using QtWebEngine::initializeas illustrated by the following code snippet:. To make sure that OpenGL context can be shared between the GUI and render processes, the web engine must be initialized by using QtWebEngine::initialize in the application main source file, as illustrated by the following code snippet:. By default, links to different pages load within the same WebEngineView object, but web sites may request them to be opened as a new tab, window, or dialog.
The following sample QML application loads a web page using the url property:. However, the DOM can be inspected and adapted by injecting scripts. The DOM of a page is constructed when the document is ready, typically when the page is completely loaded.
Therefore, executing scripts as soon as a document is created is not suitable for DOM operations, where one has to wait until the DOM is ready. In addition, an injected script shares the same world as the other scripts executed on the page, which might lead to conflicts.September This process has appeared after this new update.
I don't know if it has anything to do with this new Origin running like absolute rubbish, but the process is taking up just as much memory as 'Origin. Then there's also the Origin Client Service process running as well. Its using over mb of ram whilst its doing nothing. So is there away you make the new Origin a little bit leaner like. Before other say just close the Origin client etc i understand that but if you think the same in logic the GPU and CPU are pegged even before you load the game of choice, also some games will not work after launching the game and closing origin so i can't even reduce the CPU load.
I would suggest uninstalling and reinstalling Origin. Might have gotten a bad download. That is not a resource hog. Yes Origin is one of those start on boot items. I would also check to see what else is using your CPU when the computer is idle, it might be a screen saver, a background maintenance task or another application that starts when you reboot. You can also boot in safe mode to see if the problem remains with only required services and the OS running.
Here's how Clean Boot.Pengalamanku jolok bontot cikgu
September - last edited September I will give the uninstall reinstall trick another go hopefully i will not fudge my game installs like last time.
Edit: Is there a Beta version direct download as it will not allow me to go back to beta again. So i can't check if it fixed the issue or not. So after uninstalling and reinstalling origin. Then waiting for the Beta update its now only using 1. So long as it's QtWebEngineProcess and not qtwebengineprocess, it's fine. It is digitally signed by Dropbox and, it's used by several application, Steam, Glyph, Origin, and some browsers. Multiple copies running is normal when you have more than one application running that uses the process.

Qt Forum. Log in to post. No one has replied. For anyone interested, I solved the problem. None of the qtwebengine projects will run outside of QtCreator unless you run macdeployqt on the package first. But in order to get macdeployqt to work you need to specify the path to the Qml root directory of your project.
I report this issue to official and but them not yet solved, you can vote it. My solution is automatically zoom in webpage when the dpi is high.
That's a Known Issue, qt official will fix it in qt 5. Solved: the cause was the stub in mesa3d drm backend. It's solved by altering the backend. Hans-Dijkema I have yet to try Qt 5. Did you ever find a solution so that you don't have to call a function that then emits a signal? I am running into this problem as well and we have several functions. My other attempt at bulding qtwebchannel into a proper set of install files tried to mimic this.
What part of that spec file is the binary I can double check? Where should qtwebchannel be installing? I know my catch all package installs the headers, but what piece of that install spec denotes the binary for me to check that it built? I'm sorry but I really can't say, I have no idea what that file is or how it's used.
It looks like a shell script, but I don't recognize the interpreter. I'm sorry I can't be more specific, but I reiterate I haven't built anything this way, and only observed that there's no build step for said module. I'm sorry for the delay, I was pretty busy these two days. Thank you. I had the same issue but I did not have enough time to investigate.
So I will try to update graphics driver as you did. SGaist agarny Looks like this is fixed with QT 5. I used the brew version.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Or what is your motivation for the future with PS before it uses very outdated technologies? And I have an additional question: I know a lot of WebKit functionality is implemented by the browser.
But which steps are needed to upgrade to support the ES6 syntax? There was some discussion about switching to Chromium Embedded Framework. Not sure where the prototype is at. But I'll write them here. Right now we are working on bringing new and latest WebKit. This is our primary goal. Moving to Chromium is impossible at the moment. Google is working on a headless shell and this shell is far from complete. We can't move to it. But we don't drop it from our plans. Consider the situation, it's not likely going to happen in the near future.

Dark Mode Beta - help us root out low-contrast and un-converted bits.Chromium, which is used in WebEngine to load and render web content, is also designed to make use of hardware acceleration as much as possible. This document describes the overall concepts of how web contents actually gets rendered into a web engine view and how the Qt and the Chromium parts interact. It also tries to at least describe the basic concepts of rendering in Chromium and provides further links to the Chromium documentation for reference.
Chromium is designed to make use of hardware acceleration for rendering and painting as much as possible. In order to do this, Blink moved away from the traditional model of painting directly into software bitmaps to the model of recording the painting calls in Skia Pictures SkPictures which records the draw commands and can be used later to actually paint the RenderObject it was created for.
Through a series of compositing steps, RenderLayers are converted to GraphicsLayers, which are then associated with compositing layers that can be GPU backed and drawn using hardware acceleration. The compositor will then divide up the layers into a number of tiles and only rasterize the tiles that are either in the viewport or adjacent to the tiles in the viewport to enable faster scrolling while still saving memory and resources by leaving out tiles that are further away from the viewport.
These tiles and layers will then be composited into a compositor frame, which mainly consists RenderPasses and TransferrableResources. This data is what is handed off to Qt WebEngine and used to generate nodes for the Qt Quick scene graph. The data that Chromium passes over to Qt basically consists of a list of RenderPasses and an array of TransferableResources that are used by the RenderPasses.
These resources would for example be textures that have been uploaded to the GPU by Chromium in case if hardware acceleration is used, or they could also be handles to bitmaps in shared memory in case software rendering is used. The resources are associated to synchronization points so that they can be used across threads. What happens in DelegatedFrameNode::commit is that first, the objects that were created for the previous frame except the scene graph nodes themselves are saved.
The scene graph nodes used for the previous frame are deleted. Then, the list of resources is traversed. If the resource was already in use previously, it's reference count is increased, otherwise, a new ResourceHolder wrapper is created for it.Anne curtis
Then, the list of RenderPasses is traversed, with the root RenderPass being the last one. It is attempted to reuse these objects from the previous compositor frame if a RenderPass with the same ID was already present there.
After applying the DrawQuad's geometry and other resources such as color or texture to the scene graph node and intializing the texture for it, the node is appended to the list of children.
If a DrawQuad or a collection of DrawQuads has clip rects, opacities or transforms applied to them, the corresponding scene graph nodes will be prepended to them in the scene graph node tree.
The resources used by a quad will be removed from the list of resource candidates and be save in the DelegatedFrameNode's collection of currently used resources.PyQt5 Browsing Website With PyQtWebEngine - Python GUI Tutorial
After this has been done for all RenderPasses, the resources that were in the resource candidate list, but not used in this frame, are returned to Chromium in order to free them. DelegatedFrameNode::preprocess goes through the list of resources that have been marked as in use by DelegatedFrameNode::commit and assembles a list that contains the resources whose textures have not been fetched from the Chromium GPU thread where they were generated to the main thread.
After assembling the list, it will go through it and post a task for each of the textures to run pullTexture for it on the GPU thread and wait until all these tasks have completed on the GPU thread. At the end, the list of QSGLayers that have been created for the non-root RenderPasses will be traversed and the scene graph will be requested to update each layer's rendering. In a number of scenarios, we disable using the GPU e. In this case, the GPU thread will not be initialized at all and the renderer processes will use Skia's software rasterizer to generate bitmaps that are copied to the browser process using shared memory.
This happens during the creation of scene graph nodes in DelegatedFrameNode::commit. The code that does the actual copying can be found in ResourceHolder::initTexture.
