We now use click() or focus() in JS if possible, or manually follow links in a
href attribute.
While this probably introduces some new corner cases, it fixes a handful of
older ones:
- window.open() in JS can now be handled correctly as we don't need hacks in
createWindow anymore.
- Focusing input fields with images now works - fixes#1613, #1879
- Hinting now works better on QtWebEngine with Qt 5.8 - fixes#2273
Also see #70.
Before, we used the same logic for QtWebKit and QtWebEngine, where we
simply set an attribute on the tab on a mousePressEvent and then handled
opening links in acceptNavigationRequest.
However, this caused random links to pop up in new tabs (probably to
things being much more async?) on QtWebEngine, so we now handle those
cases in createWindow and only use override_target from the tab there.
Fixes#2102.
When we hide the context menu on QtWebEngine, we get a mouse event
relative to the QMenu in the filter, which means tab.elements.at_pos
will get called with a negative position (and thus assert) or at least a
wrong position.
This moves various stuff around and out of QtWebKit code:
- open_target and hint_target are now in TabData, not on the WebPage
- As much as possible got extracted from WebPage.acceptNavigationRequest
to AbstractTab._on_link_clicked, with a new link_clicked signal added
to WebPage. However, we need to decide whether to handle the request
in this tab or not inside acceptNavigationRequest, so we have some
code duplicated there and in WebEnginePage.acceptNavigationRequest.
- _mousepress_opentarget (i.e., setting the open_target) is now handled
in MouseEventFilter, not in WebView.
For some reason, when e.g. visiting duckduckgo and then heise.de,
QtWebEngine suddenly gets a new QOpenGLWidget as focusProxy.
We install an extra eventFilter observing the ChildAdded event and
re-adding the MouseEventFilter when that happens.
