SMARTGWT - 从SectionStackSection中删除DynamicForm [英] SMARTGWT - delete DynamicForm from SectionStackSection

问题描述

我有同样的问题，提到这里。这个问题被误解了，我没有评论的特权，所以我创建了这个问题。他想从SectionStackSection对象中删除一个DynamicForm。我的情况如下：我通过使用setFields（FormItem ... fields）方法向SectionStackSection添加了一些DynamicForm对象，并且我还添加了一个Button，用于从SectionStackSection中删除此FormItem。问题是一样的。也试过了DynamicForm.removeFromParent（），但是父对象在DynamicForm中为null。

编辑：这就是我的SectionStack的构建：

  SectionStack 
 SectionStackSection 
 DynamicForm df1 //通过SectionStackSection.addItem（df1）添加
按钮btn1 //通过DynamicForm.addChild添加（btn1）
 ClickHandler ch1 
 FormItem [] fiList1 //通过DynamicForm.setFields（fiList1）添加
 DynamicForm df2 //通过SectionStackSection.addItem（df2）添加
按钮btn2 / /添加到DynamicForm.addChild（btn2）
 ClickHandler ch2 
 FormItem [] fiList2 //通过DynamicForm.setFields（fiList2）添加
 // ... ...添加更多DynamicForm对象
 DynamicForm dfX 
 Button btnX 
 ClickHandler chX 
 FormItem [] fiListX 
 SectionStackSection 
 // ... 
 // ... 
  

按btn1举例，df1应该被删除。

解决方案

只需在下方行

即可

  dynamicForm.getElement（）removeFromParent（）; 
  

I have the same problem, that is mentioned here. The problem got missunderstood and I don't have the privileg to comment so I created this question. He wants to delete a DynamicForm out of an SectionStackSection object. my situation is the following: I added some DynamicForm objects to the SectionStackSection by using the setFields(FormItem... fields) method and I also added a Button to delete this FormItem out of the SectionStackSection. The problem's the same. Also Tried DynamicForm.removeFromParent(), but the parent object is null in DynamicForm.

EDIT: That's how my SectionStack is build:

SectionStack
  SectionStackSection
     DynamicForm df1 // added via SectionStackSection.addItem(df1)
       Button btn1 // added via DynamicForm.addChild(btn1)
         ClickHandler ch1
       FormItem[] fiList1 // added via DynamicForm.setFields(fiList1)
     DynamicForm df2 // added via SectionStackSection.addItem(df2)
       Button btn2 // added via DynamicForm.addChild(btn2)
         ClickHandler ch2
       FormItem[] fiList2 // added via DynamicForm.setFields(fiList2)
     // ... some more DynamicForm objects added
     DynamicForm dfX
       Button btnX
         ClickHandler chX
       FormItem[] fiListX
  SectionStackSection
    // ...
  // ...

By pressing btn1 for example, df1 should be deleted. The SectionStackSection should be stil shown.

解决方案

Simply call below line

dynamicForm.getElement().removeFromParent();
