QtWebEngine

Here are the screenshots depicting the problem:
works from web
fails from local drive

Just an FYI, disabling network adapters (used by virtual machines) in Device Manager solved the sluggishness for me.

Hi Rahul,

I am looking something similar i.e. logs of Qt framework. Refer https://forum.qt.io/topic/58566/how-to-print-logs-qdebug-qwarning-qcritical-qfatal-of-qt-framework-libraries-itself

Try using --log-level=0. It might work in your case.

Thanks,

have you tried a simple alert from your Qt to Js?

QString jsCode = "alert('helloWorld');"; ui->webView_studio->page()->mainFrame()->documentElement().evaluateJavaScript(jsCode + "; null");

if this works then the problem is the syntax of your javascript inside Qt.

@p3c0 That worked, thanks for your help.

Hi,

Now you can use the following line for a QWebEngineView object :

webview ->page()->profile()->setCachePath("C:/Users/yourUserName/AppCacheFolder");

See you.

evaluateJavaScript is your friend

Exemple of code working with Jquery, replace with javascript code

QString jsToExecute += "$('#login-btn').click(); "; ui->webView_login->page()->mainFrame()->documentElement().evaluateJavaScript(jsToExecute + "; null" );

Disregard my previous post, cookies policy can be set in the QWebEngineProfile owned by the QWebEnginePage owned by the QWebEngineView, like this: ui->webView->page()->profile()->setPersistentCookiesPolicy(QWebEngineProfile::NoPersistentCookies);

The page pointer remains the same for my purposes, at least.

Hi and welcome to devnet,

If you can reproduce this easily with a minimal compilable example, you should go to the bug report system to see if it's something known. If not please consider opening a new report providing that example and the guidelines to trigger the bug.

Hello.

I just did a Test Deploy on a Windows 10 and a Windows 7 Clean VM Machine. Qt Version is 5.5.0

I know this is about Embedded Linux and around 5 Months old.
But I have the same Problem. It is exactly the same Error Message. Does anybody found a real working Solution yet? The .pak File is in my Application Main Folder. I created a qt.conf and tried the following Settings:

[Paths] Prefix=<QCoreApplication::applicationDirPath()> Prefix=<> Prefix=<\> Prefix=<&PWD>

Nothing worked so far. I could not find the answer, how to tell Prefix to use the current Directory.
In addition: Has anybody created a BR yet? If not, I can do this.

Thanks
Oliver

EDIT01: Finally I found a way to make it work:

[Paths] Prefix=.

Time will tell if this will bring up other Bugs, Glitches etc.

OK, so I just tried it again and now it works. No idea what's different from earlier this week, but I'm glad it works now. :]

Waiting online~~~

Hello.

Yesterday I have tried the following and failed:

I have changed the Part from Line 1 in File '..\qtwebengine\tools\qmake\mkspecs\features\functions.prf'
from:

!win32-msvc2013: !contains(QT_CONFIG, c++11) {

To:

!win32-msvc2015: !contains(QT_CONFIG, c++11) {

And in Line 17 from:

linux-g++*|win32-msvc2013|macx-clang: return(true)

To:

linux-g++*|win32-msvc2013|win32-msvc2015|macx-clang: return(true)

As I am absolutely new to QtWebEngine, I am not sure If this is enough. But after I found an Entry at code.qt.io from Michael Brüning called "Print a more descriptive warning when a build is skipped.", I thought I would give it a try.

The Result is the following Error:

Using extra options found in c:\qt5src\qtwebengine\src\core\qtwebengine_extras.gypi Traceback (most recent call last): File "C:/qt5src/qtwebengine/tools/buildscripts/gyp_qtwebengine", line 147, in <module> args.extend(['-Goutput_dir='+ os.path.relpath(output_dir, qtwebengine_root)]) File "C:\Python32\lib\ntpath.py", line 528, in relpath % (path_prefix, start_prefix)) ValueError: path is on drive D:, start on drive c: Project ERROR: -- running gyp_qtwebengine failed -- NMAKE : fatal error U1077: '(' : return code '0x3' Stop. NMAKE : fatal error U1077: 'cd' : return code '0x2' Stop. NMAKE : fatal error U1077: 'cd' : return code '0x2' Stop.

['Python32' is Python 32-bit but it contains the latest Python 2.7 Package. Bad old naming leftover.]
I dont know enough about QtWebEngine and nearly nothing about Python. I have to wait for a fix from someone who knows what (s)he's doing. My Bug Report has set to P2 - so with any luck, this will be fixed in 5.5.1

Until then I have to work with a pre-built MSVC 2013 Package. My Tool is far from ready to be released. So I still have time to wait for a fix for WebEngine and and a fix for ICU as well.

Have a sunny weekend everyone :)
Thanks
Oliver

Well, it was caused by a QGraphicsEffect on the QWidget.
After removing it, the QWebEngineView worked without any flaws. weird.
