Qt web widget is not supported

[VRonin]

WebKit is not part of Qt since Qt 5.6 if I'm not mistaken. Qt now uses webengine for the same tasks. There is a porting guide available here: https://doc.qt.io/qt-5/qtwebenginewidgets-qtwebkitportingguide.html

additionally to @VRonin
QtWebEngine is it's own module and not part of the default precompiled libs. make sure you select it when downloading:

@VRonin is it possible to use the webview/webkit in qt 4 version

[sankarapandiyan]

@J-Hilk Any other method to do this , its not possible to reinstall it , can you give me any other suggestion

[J.Hilk]

@sankarapandiyan
well, there's always building modules by hand. There are countless tutorials on how to do it, depending on your OS and target device. For more information you could take a look here:

qt version is Qt Creator 4.8.2
Based on Qt 5.11.3

This is the version of the IDE not of the library you use. You can check the real version of Qt in the kits tab in the options.

the webview/webkit in qt 4 version

Qt 4 is ancient but if you mean using it in modern version of Qt then ther's a fork on github you can use
