Description
I'm going to use WebEngineView as chat window in my app because there is no simple way to handle animated emoticons in effective way. Using QWebView from Qt Widgets it was possible but now in QML I'm facing with these problems:
1) I would like to open a particular URL externally. In latest Qt version we have something like "onNewViewRequest" which I used in this way:
WebEngineView {
property string currentLink: ""
onNewViewRequested: Qt.openUrlExternally(currentLink)
onLinkHovered: currentLink = hoveredUrl
}
where link is defined as <a href='xxx' target='_blank'></a>
It crashes almost everytime. I noticed that without using Qt.openUrlExternally it seems to work.
log:

I also tried to use on "onNavigationRequested" but after clicking on URL, the WebEngineView won't allow me to append anything more inside the view (with javascript which I used previously)
Anyway onNavigationRequested doesn't exists in Qt docs so I left that method.
2) WebEngineView (javascript) won't allow me to read images from local files. Currently the only way to show emoticon is using http. Using:
experimental.settings.localContentCanAccessFileUrls: true
or anything from experimental - doesn't do anything with that.
3) There is no simple API for inserting/appending/removing stuff from HTML. I had to use runJavaScript with appropriate script. Would be nice to have similar functionality as in older QWebView.
Of course - points 2 and 3 are suggestions only
