QtWebEngine

@mecctor I took the liberty to reduct the links in your post.

I worked around the urlbar text thing with this. if url.startswith("data:"): text = self.urlbar.text() self.urlbar.setText(text) It basically works, because setHtml always forces something starting with "data:" into the urlbar. As far as the custom Html status codes / error messages, I can make a custom 404.html page on my Apache server and direct my .htaccess file to it, but that's how far I can go. Is there any "onLoadFailed" type of syntax in PyQt where I could check if a page was able to be loaded at all? I've disabled Chromium's status codes with this: settings = QWebEngineSettings.globalSettings() settings.setAttribute(QWebEngineSettings.ErrorPageEnabled, False) but if a page is offline for example, all I get is a blank page which is confusing to users.

@JonB said in select fields with a lot of data: This really should not be the case, given that QtWebEngine is just using the chromium engine. Nor should how you compile be relevant if you are just presenting QtWebEngine with some fixed HTML. So do you have more than that going on? Are you counting your code time to generate the list of the selects? Can you show a minimal example of your issue? In my project I first create the complete html page and then I associate it with the WebEngine dynamically. The fields, in this case, are three select a bit long .. same this: var urlEngineFormPgm = splitViewComponent.txtCurrentPath + "/html/" + namefilehtml; var objRectPgmCreate = componentQmlRectPgm.createObject(objMainWindow, {"xProgram": positionX, "objectNameProgram": objName, "textProgram": "Loading. . . .", "visibleProgram": true, "urlPgm": urlEngineFormPgm, . . . . where urlPgm is alia og WebEngine property URL I have never calculated the execution time but I notice big differences between debug and release but also in release if I have a computer with few resources everything becomes slow .. The same page opened with crhome behaves in a normal way without being slow. P.S. Is slow when I touch fields Select for open list of combobox NOT when load QML whith WebEngine

Hello QtWebKit has RTCPeerConnection functionallity? I am getting this error: https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js line 2: jQuery.Deferred exception: Can't find variable: RTCPeerConnection https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js line 2: ReferenceError: Can't find variable: RTCPeerConnection

I found a workaround for this, it isn't the best but I'll explain it for those interested: You register only one script to be executed for each injection-point, you then assign that script a specific name. If you want to inject another script you then search the script in the page script-collection, remove it from the list, append the new script code to the previous script and then insert it back into the list

thanks. I have got the same problem. HzWindow::~HzWindow() { m_webEngineView->deleteLater(); // I try this , solved the problem qApp->removeTranslator(m_curTranslator); if (m_pPrintHandler) { delete m_pPrintHandler; } } and initialize the page like this: m_webEngineView->setPage(new HzWebEnginePage(m_profile, m_webEngineView));

@Harborman This looks much better! Your lambda now passes the page as a parameter, and unlike your original index that does not change as you insert/delete other pages. Then you look up the page in the tabs during the slot to find it at that time.

I have solve width into main only for debug #ifdef QT_DEBUG bool ret = qputenv("QTWEBENGINE_CHROMIUM_FLAGS", " --remote-debugging-port=91"); #endif Where 91 is any port you want. After open browser and go link http://127.0.0.1:91 So you can you tools developer

@eyllanesc Thank you friend, that works. This question is solved. I also found the "code" button so I won't paste code here without indents in the future :-).

thanks, i have ty pass a QJsonObject and is all right

@MazyCrazy Is you issue fixed? I am facing a very similar issue. It works on certain version of Linux but have the same error as what you have on other Linux.

@JoeCFD please provide a minimal and verifiable example.

@Holiday Doesn't surprise me! You could look around the sources to understand what is going on.
