详细描述

A ContextMenuRequest is passed as an argument of the WebEngineView::contextMenuRequested signal. It provides further information about the context of the request. The position of the request origin can be found via the x and y 特性。

The accepted property of the request indicates whether the request is handled by the user code or the default context menu should be displayed.

The following code uses a custom menu to handle the request:

WebEngineView {
    id: view
    // ...
    onContextMenuRequested: function(request) {
        request.accepted = true;
        myMenu.x = request.x;
        myMenu.y = request.y;
        myMenu.trigger.connect(view.triggerWebAction);
        myMenu.popup();
    }
    // ...
}

accepted : bool

Indicates whether the context menu request has been handled by the signal handler.

If the property is false after any signal handlers for WebEngineView::contextMenuRequested have been executed, a default context menu will be shown. To prevent this, set request.accepted to true .

默认为 false .

注意: The default content of the context menu depends on the web element for which the request was actually generated.
