或者说,事件(event)表示程序某件事发生的信号,可以用来触发一段特定的代码——事件处理程序。 事件处理程序(event handler)是应用程序中的一个函数,当事件发生时调用它。 当事件发生在控件(widget:组件、小部件、控件)上,调用事件处理程序时,我们称之为绑定( binding)。绑定就是将事件和事件处理程序建立联系。 Tkin...
例如,为FC函数配置的handler为main.handler,那么函数计算会去加载main.py中定义的handler函数,并从handler函数开始执行。 event:您调用函数时传入的参数。在Python 2.7运行环境中,类型为String。在Python 3运行环境中,类型为Bytes。 context:为您的FC函数调用提供在调用时的运行上下文信息。 示例一:解析JSON格式参数 ...
