bug-19549-Qt-5-6

Increased importance as Qt < 5.6 has a bug on some Linux configurations regarding missing mouse event compression.

User kislinsk has pushed new remote branch:

bug-19549-Qt56-2

For Qt 5.6 we also need to upgrade VTK to version 7. Hence I merged T19548 into bug-19549-Qt56-2. Installation of VTK 7 does work in Debug configuration now. Also added a patch for CTK to make it compatible to Qt 5.6.

bug-19549-Qt56-3

Please use bug-19549-Qt56-3 from now on. WebEngine migration is still work in progress. Everything should compile already, though.

linkClicked isn't a signal anymore. We need to find another way to connect DelegateMeTo again. Solution hint in the migration guide (https://wiki.qt.io/Porting_from_QtWebKit_to_QtWebEngine):

QWebPage::setLinkDelegationPolicy

There is no way to connect a signal to run C++ code when a link is
clicked. However, link clicks can be delegated to the Qt application
instead of having the HTML handler engine process them by overloading
the QWebEnginePage::acceptNavigationRequest() function. This is
necessary when an HTML document is used as part of the user interface,
and not to display external data, for example, when displaying a
list of results.

Overriding acceptNavigationRequest() doesn't work for URLs with qthelp scheme. There's another approach based on QWebEngineUrlSchemeHandler:

Okay, qthelp pages work again.

TODOs:

• Crash on Workbench close when help is/was opened
• d3 based histogram in measurement toolbox.

We should consider merging bug-19549-Qt56-3 as soon as the dashboard is green again. The d3 histogram is suitable for a separate bug. The crash should be fixed before merging, though.
