QML notes on WebEngine

Versions that support WebEngine and WebChannel

• Origin of WebEngine module library inclusion dates back to MuseScore Connect
• Musescore 3.6.2 for Windows has WebEngine (and WebChannel) support. Not on Linux and Mac versions.
• Musescore 4.0 (all platform) uses OAuth. WebEngine support removed Jun2021, see github

Right click issue

• It seems WebEngineView unifies left and right mouse button to one event (simplified to a simulated tap?)
• To disable its context menu upon right mouse button use:

WebEngineView {
  onContextMenuRequested: request.accepted = true
  //add codes here for DIY menu
}

buggy mouse events:

DOM bubbling exist unexpectedly in these events, also event.target==currenttarget unexpectedly in bubbling

• mouseenter
• mouseleave

It seems WebEngineView always simulate a pen tip drag when mouse movement happens, ie the mouse is always pressed in the following event ( mouseevent.button==0 )

• mouseover
