Using QWebkit for windows with mingw

[Thank You]

@JKSH
Hey, I have been using Qt5.12.8 and has other dependencies too.
Will code compiling in Qt 5.12.8 would compile in QT 5.15 ???

[SGaist]

Yes, that's one of the strength of Qt.

[Thank You]

I installed QT 5.15.2 and build with it. Got all dependencies with windeployqt and added libxml2-2.dll libxslt-1.dll.
It now shows error zlib1__.dll not found.
I searched in whole qt directory but couldn't find one so I managed to download zlib1.dll not zlib1__.dll from dll-files.com.
I renamed zlib1.dll to zlib1__.dll and placed in binary directory. I don't know if this is good to do.
Where is zlib1__.dll located in QT??? OR it isn't related with QT?

Atleast it is working in 64bit version but shows TLS initialization failed Which is connected to OpenSSL so I am sure I will solve this problem.
Edit:
I copied libcrypto-3-x64.dll and libssl-3-x64.dll to executable directory but couldn't get it working
Now some problems that I can't figure out are:
It doesn't work with debug
Most importantly it doesn't work with 32 bit which is most for me.
How can I obtain it?

[Thank You]

@Thank-You
Now after installing another version of openssl it is working on 64bit.
I couldn't make it work in 32bit.
And I found that many websites doesn't considered it as supported version.
I found that we can embed existing application to QT application but has no idea.
Main purpose of this is to run services like gmail , google docs and other servuces.
Which would be good?
I was just searching abt this yesterday and found about running application. Could you give links of working docs about this?

I will create new question abt this

Web engines are very difficult to maintain because of security requirements. That is why the Qt Project replaced Qt WebKit (which was mostly maintained by the Qt folks) with Qt WebEngine (which is mostly maintained by the Chromium folks).

@Konstantin-Tokarev has done a great job making Qt WebKit compatible with recent versions of Qt, but the last update was over 1 year ago. Lots of security vulnerabilities have been discovered in WebKit since then; that is why many websites don't consider it as a supported version.

Qt WebEngine for desktop platforms; Qt WebView for mobile platforms.
