When i have a tree+layout+tabber..how can i add content

i am so sorry trouble dhtmlx developers again.
now i use htmlx4.0 ,
i use tree,layout,tabber to do a page.

when i click a leaf or directory of tree, i will add a tab in my layout
but the added tab display,it also can execute a method ,such as javascript method or attach url…

Google blocks attach “google.com” link in iframe, we can’t fix it. Any other link you can attach the next way:
dhtmlx.com/docs/products/dhtmlxT … h_url.html - Load data in tabbar through iframes
dhtmlx.com/docs/products/dhtmlxT … _ajax.html - Load data in tabbar by ajax
