sencha touch:dynamically add/remove components to panels

i extended a panel containing

-Panel 
   -Toolbar with button

and i registered it as a xtype using Ext.reg().There is one more panel in which i want to add the registered xtype and did it. How can i add/remove a component/html content dynamically to the outer panel on button click.

Thanks in a开发者_JAVA百科dvance.

I hope it will help you :

var component = ...;
var position = 0;
component.insert(position, new Ext.Panel({html : "inserted"}));
component.doComponentLayout();

While an older question, you can use .add or .addDocked

This is far simpler since it allows the panel to add the element and manage the height ect.
