Hi Pascal,

Florian is right, several related issues have been fixed in 5.9.
However, there are some fixes in 5.8 too. For example, this fix a
virtual keyboard issue on macOS:
https://codereview.qt-project.org/#/c/181969/3 and here is a test for
virtual keyboard: https://codereview.qt-project.org/#/c/180414/ So
theoretically the virtual keyboard works but to be honest I haven't
tried it with widget yet :) The QtWebBrowser (what is quick based)
works: http://code.qt.io/cgit/qt-apps/qtwebbrowser.git/

If you still can reproduce the issue with 5.9 please create a new bug
report at https://bugreports.qt.io Please add the following details to
the report:
- Which OS is affected
- Which API you use (I suppose widget)
- Which Qt version you use

If you could add a minimal example with virtual keyboard issue that
would be very helpful. If you could run the corresponding auto test
(tst_QWebEngineView::softwareInputPanel) and share the result that would
be also very helpful :)

Best Regards,
Peter
