我正在使用三个对话框（名称为：Box1，Box2和Box3），如下所示： -
基本计算是在Box1和Box2上进行的，如何在Box3上显示第三个对话框的计算总和？
@Rule
public final ExpectedException expectedException = ExpectedException.none();
@Test
public void testExceptionCause() throws Exception {
expectedException.expect(ExecutionException.class);
expectedException.expectCause(isA(CustomException.class));
throw new ExecutionException(new CustomException("My message!"));
}
正在Box1和Box2上执行简单算术，我希望结果的总和显示在第三个对话框上（Box3）
我该如何完成这项工作？
代码基于wxpython classic和python 2.7

您需要通过 init 方法将从每个对话框收集的信息传递到下一个对话框。这是一个快速工作的例子
