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 property provides the origin of the request.

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();
    }
    // ...
}

特性文档编制

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.
