tab activate event help

[MoShAn480]

Hi,

I am having some trouble understanding how events work in Ext. I have the following code:

var id = 123;
dialogTabs.getTab(tabId).addListener('activate',activateRequestTab);

what is the parameters being passed to my "activateRequestTab" function? I would like to pass the "id" parameter to the function so every time I swicth tabs, i can carry out updates, and other related tasks, related to the id.

Thanks.

You can use:

var id = 123;
dialogTabs.getTab(tabId).addListener('activate',activateRequestTab.createDelegate(scope, [id]));

scope depends on the context you want to run activateRequestTab in. Can be this, tab, window, or else

If you need to preserve original argument (which is tab index) use:

dialogTabs.getTab(tabId).addListener('activate',activateRequestTab.createDelegate(scope, [id], true));

Although I'm using Ext2.2, I thought it was a good idea to reuse this topic.

I have a more primary doubt/bug than the first described here. Excerpt of my code:

tpanel = new Ext.TabPanel(
                {
                    height: 600,
                    width: 950,
                    deferredRender: false,
                    defaults: { closable: true },   //tabs only
                    tbar: [
                      ....
                    ]
                     ,
                    listeners: {
                        activate: function(panel) {
                            alert('here!');
                        }
                    }

                });


                tpanel.render('filegrid');

That 'alert' on event 'activate' never fires, although I switch,close and open multiple tabs. Any hint ?


Thanks in advance
