However, when I run this code, there is no visible change, until after the code has run, and then it changes to "Processing 9" 0-8 are not ever shown. Is it because it is within the loop? private void button1_Click(object sender, EventArgs e) { for (int i = 0; i < 10; i++) { label9.Text = "Processing " + i.ToString(); Thread.Sleep(1000); } } EDIT: X-Tech's code worked but when I tried to incorporate it into my code, I get

SSCCE: import javafx.scene.control.Label; import javafx.scene.layout.HBox; import javafx.application.Application; import javafx.scene

k8s之Labels，Daemonset，Job资源对象

阅读更多关于 k8s之Labels，Daemonset，Job资源对象

Label（标签）我们为什么要使用label呢？当相同类型的资源对象越来越多，为了更好的管理，才按照标签分为一个小组，为的是提升资源的管理效率。 lable是附着到object上（例如pod）的键值对。可以在创建object的时候指定，也可以在object创建后随时指定。Labels的值对系统本身并没有什么含义，只是对用户才有意义。 "labels": { "key1" : "value1", "key2" : "value2" } 语法和字符集 Label key的组成： * 不得超过63个字符 * 可以使用前缀，使用/分隔，前缀必须是DNS子域，不得超过253个字符，系统中的自动化组件创建的label必须指定前缀，kubernetes.io/ 由kubernetes保留。 * 起始必须是字母（大小写都可以）或数字，中间可以有连字符，下划线和点。 Label value的组成: 不得超过63个字符起始必须是字母（大小写都可以）或数字，中间可以有连字符，下划线和点。常用的，多维度标签分类：版本标签（release）： stable（稳定版），canary（金丝雀版本），beta（测试版）环境类（environment）： dev（开发），qa（测试），production（生产），op（运维）应用类（applaction）： ui（设计），as（应用软件），pc
