C GTK +定期事件以更新UI [英] C GTK+ periodic event to update the UI

问题描述

如何在定期事件中更新GTK +接口.例如，假设我要更新一个包含每200毫秒时间的文本字段.通常这是怎么做的?

How can I update a GTK+ interface on a periodic event. For example, let's say I wanted to update a text field containing the time every 200 milliseconds. How is this typically done?

更新:

另一个问题(如何在gtk中执行定期作业应用程序?)提到g_timeout_add.这是执行此操作的最佳方法吗?据说在那个线程中效率可能不高?
