In this tutorial, you'll learn about the Tkinter event binding and how to use it to associate a function to an event of a widget. A common technique -- employed by tkinter itself in some cases -- is to generate the event on the root window, Python Tkinter Events In Tkinter, events are actions that occur when a user interacts with the GUI, such as pressing a key, clicking a mouse button, or resizing a window. event_generate(sequence, **kw) Generate an event SEQUENCE. 事件处理 一个GUI应用整个生命周期都处在一个消息循环(eventloop)中它等待事件的发生，并作出相应的处理Tkinter提供了用以处理相关事件的机制. 阅读更多： Tkinter 教程 使用 event_generate 函数设置数据值 event_generate 函数是Tkinter中的一个方法，用于在特定的事件被触发时生成虚拟事件。 这个函数可以将多种事件类型与特定的绑定关联， Comme evenement ne s'est pas concrètement réalisé, l'objet event généré par la classe tkinter. tkinter event_generate模拟按钮点击 在使用tkinter构建GUI应用程序时，经常会遇到需要程序自动触发按钮点击事件的情况。 这时就可以使用event_generate方法来模拟按钮点击事件。 本文将详细介绍如 But Tkinter also allows you to create bindings on the class and application level; in fact, you can create bindings on four different levels: the widget instance, using bind. x, y, rootx, rooty). For example, you can use it to simulate a mouse click on a button, a key press Our program can ask the event loop to generate one of these events at a later time. In this Tkinter tutorial, we will explore how to create our own Custom Virtual Events. Or, associate the event with the root window, and bind to the root window. Button: import unittest, threading from Tkinter. However, if you don't call update before calling event_generate, the window won't be visible and tkinter will likely Generate an event SEQUENCE. )允许读取此字段。 此函数只适用于文字，我通常会传递带有文字的字典。. 处理函数可被绑定给各个控件的各 I researched a bit and it seems like what you are trying to use (data) is accepted in event_generate but there's no way to query the sent value from Tkinter (only from Tcl).
