    <p>I have a question regarding multiple inheritance in ExtJS. While I know I can simply duplicate the code to make it happens, but I want to know if there is any way to code it more efficiently.</p> <p>I have a customized <code>GridPanel</code> component in my framework, called <code>Kore.ux.grid.GridPanel</code>. It extends <code>Ext.GridPanel</code> with extra common functionalities and provides interface for REST actions.</p> <p>Soon later, my colleague wanted to have <code>EditorGridPanel</code> to be also implemented in the same manner, ie, she wants it to be editable, and at the same time, have the ability to do REST actions easily.</p> <p>My question is, is there any way I can extend <code>Ext.EditorGridPanel</code> to take up the customized <code>Kore.ux.grid.GridPanel</code> functionalities?</p> <p>Sorry for any grammar errors and I can rephrase it if it's confusing. Thanks!!</p> <p><strong>EDIT</strong></p> <p>I googled again, and I found threads saying it's impossible. Is there any better coding pattern I should follow if I have this problem?</p> <p>Thanks!</p> <p><strong>EDIT AGAIN</strong></p> <p>So sorry I found the structure that suits me.. Here is the method I found useful to me:</p> <pre><code>var Common = function(){} //abstract class Ext.apply(Common.prototype, { a : function(){}, b: function(){}... }); Ext.ux.SomePanelA = Ext.extend ( Ext.Panel, { stuff : ............ }); Ext.ux.SomePanelB = Ext.extend ( Ext.Panel, { diffStuff : ............ }); Ext.applyIf(Ext.ux.SomePanelA.prototype, Common.prototype); Ext.apply(Ext.ux.SomePanelB.prototype, Common.prototype); </code></pre> <p>Code Source: <a href="http://www.sencha.com/forum/showthread.php?48000-multiple-inheritance&amp;p=228271&amp;viewfull=1#post228271" rel="nofollow">http://www.sencha.com/forum/showthread.php?48000-multiple-inheritance&amp;p=228271&amp;viewfull=1#post228271</a></p> <p>Please again provide useful suggestions if you think you have a better solution :) Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
