A FileDialogRequest is passed as an argument of the WebEngineView::fileDialogRequested signal. It is generated when the file dialog is requested by the input element. See File Upload state .
The
accepted
property of the request indicates whether the request is handled by the user code or the default dialog should be displayed. If you set the
accepted
特性到
true
, make sure to call either
dialogAccept()
or
dialogReject()
afterwards.
The following code uses a custom dialog to handle the request:
WebEngineView { // ... onFileDialogRequested: function(request) { request.accepted = true; myDialog.request = request // keep the reference to the request myDialog.accept.connect(request.dialogAccept); myDialog.reject.connect(request.dialogReject); myDialog.visible = true; } // ... }
accepted : bool |
Indicates whether the file picker dialog request has been handled by the signal handler.
If the property is
false
after any signal handlers for
WebEngineView::fileDialogRequested
have been executed, a default file picker dialog will be shown. To prevent this, set
request.accepted
to
true
.
