对话框、文档、表单或图形控件引发的事件可以链接到宏, 这称为「事件驱动编程」。将事件与宏关联的最常见方法是工具 – 自定义菜单中的选项卡，以及「工具 - 宏 – 组织对话框...」菜单中的「对话框编辑器」控件属性窗格。
Graphical artifacts, keyboard inputs, mouse moves and other man/machine interactions can be controlled using UNO listeners that watch for the user’s behavior. Listeners are dynamic program code alternatives to macro assignments. One may create as many UNO listeners as events to watch for. A single listener can also handle multiple user interface controls.
监听器附加到对话框中的控件, 以及文档或表单事件。在创建运行时对话框或向对话框中动态添加控件时, 也会使用监听器。
本示例为 标准 库中的对话框 Dialog1 的Button1 控件创建监听器。

监听器通常与对话框打开代码一起编写。可以创建许多不同的监听器，例如用于对话框的事件处理程序，或用于文档或表单的事件监视器。
