Question

How do I change the tooltip for a panel located in a tab panel? Originally, I created a tooltip using the tabtip parameter of the panel constructor as the panel was added to the tabpanel.

You need to grab the DOM element that represents your tab’s tab strip. You can use tabPanel.getTabEl(tabID) to get the strip element. You can then grab the .x-tab-strip-text span and set its qtip property.

// be sure to set your tab's itemId
var tabPanel = new Ext.TabPanel({
   items: [{
      title: 'one tab',
      tabTip: 'something',
      itemId: 'firstTabID',
      html: 'haha wooo'
   }]
});

// later...
// .getTabEl grabs the tabstrip DOM element
// Ext.get converts it to an Ext.Element
Ext.get( tabPanel.getTabEl('firstTabID') )
   // find its descendent span that contains the tab's title text
   .child('span.x-tab-strip-text', true)
   // and set the tool tip
   .qtip = 'something completely different!';

I’d never changed tab tooltips before so I dug around the Ext.TabPanel source looking at how they set it. I learned something too 🙂
