gwt - Create custom widget and allow nested sub-elements in UiBinder -

-

I want to create a custom widget that allows the UIB to specify its nested sub-element in inder like Dockpanel may be south , answer , etc. I looked at the source code of DockPanel but found a solution. 

  & lt; My: LeftRightToolbar & gt; & Lt; Left & gt; & Lt; Six buttons / & gt; & Lt; / Left & gt; & Lt; True & gt; & Lt; Six buttons / & gt; & Lt; / True & gt; & Lt; / Mary: LeftRightToolbar & gt; My custom  & lt; Left & gt;  and  & lt; Right>  can have multiple sub-nodes

update: code>? Code if I add more than one widget does not compile.

First of all - and lieutenant; Left & gt; and & lt; True & gt; should be in the same namespace as the LeftRightToolbar , so it and & lt; My: right> .

Secondly, you need to annotate two methods in LeftRightToolbar with comment: 

  @iChild (tagname = "left") Add Zero (widget widget) {left.add (widget); } @IiChild (tagname = "right") Zero addToRight (widget widget) {right.add (widget); }

Method addToLeft to & lt; My: left & gt; The tag will be asked to add the specified widget & lt; My: right> The tag is controlled by the addToRight .

If you want to add multiple widgets to your custom tags, then in the container, like FlopNell .

In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
