詳細描述

A FormValidationMessageRequest is passed as an argument of the WebEngineView::formValidationMessageRequested signal. It is generated when the handling of the validation message is requested.

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

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

WebEngineView {
    // ...
    onFormValidationMessageRequested: function(request) {
        request.accepted = true;
        switch (request.type) {
            case FormValidationMessageRequest.Show:
                validationMessage.text = request.text;
                validationMessage.x = request.x;
                validationMessage.y = request.y
                validationMessage.visible = true;
                break;
             case FormValidationMessageRequest.Move:
                break;
             case FormValidationMessageRequest.Hide:
                validationMessage.visible = false;
                break;
             }
    }
    // ...
}
