		callback: this.submit_callback,
		title: this.egw().lang(this.dialog_title),
		buttons: buttons,
		minWidth: 500,
		minHeight: 400,
		width: 400,
		value: data,
		template: this.egw().webserverUrl + this.TEMPLATE,
		resizable: true
	}, et2_dialog._create_parent('api'));
 * ```
 *
 * with this:
 * ```ts
 * this.dialog = new Et2Dialog(this.egw());
 * this.dialog.transformAttributes({
		callback: this.submit_callback,
		title: this.dialog_title,
		buttons: buttons,
		width: 400,
		value: data,
		template: this.egw().webserverUrl + this.TEMPLATE
	});
 document.body.appendChild(this.dialog);
 * ```
 * Dialog size now comes from contents, so it's better to leave width & height unset.
 * Set minimum dimensions in CSS.
 * Title & message are translated by Et2Dialog
 * @deprecated
