The Captioned problem needs to be addressed because of a workaround that i am working on that involves whenever i zoom in my image in Image component ,i.e. setContent to it then i should have the horizontal scroll set to the right.This involves a textbox at that corner and after i setcontent to the image i do txtbx.setFocus(true); This only work randomly and not very often because server updates the Image Content after i have set focus and hence it fails.However this would work if i set focus to the textbox only and only when i successfully update the client Image with the new zoomed content ,so for that i need to listen to some event like onSetContent and the do txtbx.setFocus(true); ,only if it is possible to do so.

This is just a workaround as nothing else could be found. I am usign zk 5. If any other methods or any other workarounds are there to achieve this,please suggest.

Thanks.

Using client side javascript's onload on the Image component, i was able to listen on everytime the src of the same Image Object is changed.

zk.Widget.$('$panelalt').$f('chq_img').$n().onload=function()
    {
    zk.Widget.$('$panelalt').setScrollLeft(1020);
    }
