    Default How to send mouseWheelEvent to SWF, loaded to QWebView

    Good day!

    I have a program, written in C++, using Qt 5.5.1 (can't switch to another version), running under Windows (7 or 10, doesn't matter).

    So I have some FlashWidget, subclassed from QWebView. It loads html file, parses it and replaces %1 with appropriate path to *.swf

    Qt Code:
    1. <object
    2. class="flashPlayer"
    3. width=90%
    4. height=100%
    5. type="application/x-shockwave-flash"
    6. id="bridgemovie"
    7. data="%1" >
    8. <param name="allowScriptAccess" value="always"/>
    9. </object>
    To copy to clipboard, switch view to plain text mode 

    SWF file has event listeners on mouse events: mouse down, up and mouse wheel

    Qt Code:
    1. addEventListener(MouseEvent.MOUSE_WHEEL, zoom); //"zoom" is just some internal function
    2. addEventListener(MouseEvent.MOUSE_DOWN, mouseDown1);
    3. addEventListener(MouseEvent.MOUSE_UP, mouseReleased);
    To copy to clipboard, switch view to plain text mode 

    Problem: Dragging and clicking works pretty well, but loaded SWF doesn't receive wheel events. I can't modify SWF code, only C++ and HTML parts. So, how I can natively pass mouseWheel event from JS (or, perhaps, QWebView, if allowed so) to the loaded SWF file?
    P.S. I've tried loading SWF with QAxWidget, and wheelEvent is received, but there are some rendering problems, so I'm trying to repair solution with QWebView.

    Well, it looks like a bug in QWebkit, because there is no such problem in newer versions and QWebEngine. Will try use QAxWidget instead.

    There are also some developers working on updating QtWebKit https://github.com/annulen/webkit/wiki

    Cheers,
