详细描述

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 () 或 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;
    }
    // ...
}
