A request for showing a context menu. 更多...
import 语句: | import QtWebEngine 1.10 |
Since: | QtWebEngine 1.4 |
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.
