我有一个需要为申请创建许多表格的情况,表格都位于同一个包中。它们的名字有:A11111.java,A11112.java等。
当用户在导航Pane 中单击用户时, 我希望将窗体装入标签项目并显示窗体。 问题是我要通过将窗体名称附加到位置上来动态生成窗体的名称, 如字符串窗体Name = “ com.foo. appName. client. forms” + e. getData (“ formCode ”) ; 类似的东西, 即用户点击的事件 。
我研究了几种反省方法,但你无法向他们传递一个衍生的字符串。 如何最好地做到这一点? 几个文章提到使用发电机,但我迷失了试图理清其逻辑,与显示表无关。
请注意,我不会将任何变量传递到表格中, 也不会用 Java 文件的形式称呼任何方法,
提前感谢
如果您通过班级装载器重新瞄准懒惰的加载课程, 就像您在使用 < a href=" http://sourcemaking.com/ deign_patterns/comorder/java/2#" rel="nofollow" > 命令设计模式 时那样, 注意它无法在 GWT 应用程序中完成, 如 < a href=" https:// developers.google.com/web-toolkit/doc/1. 6/RefJreEmultulate" rel="no follow" > JRE 模拟框架只提供JRE < /a > 中可用的类型和/或方法的子集, 因此大多数反射 API - 如 < codection > for () forName > - 将无法使用。
而不是懒惰的加载课程, 从向 DOM 发送懒惰的部件的角度来思考。 这可以通过在模块负荷上对您所有的形式类进行即时处理来实现, 但只能通过制表符切换。 将您所有的自制相关功能都放入 onRender () 回调中, 您可以返回 :
public class FormItem extends TabItem {
@Override
protected void onRender(Element parent, int index) {
super.onRender(parent, index);
// render related functionality
}
}
