document navigators not working

i have used the xtreame toolkit library in my MDI application.

i have created the ribbon bar.So whenever we open the document,it shows the document name in the bar below the ribbon bar. In this bar there,there are 3 buttons in the right side ,left-right navigators and close button.

from these 3 buttons,my close button is working but the navigator buttons are not working. i think they are not even enable.whenever we click on these buttons nothing is happening.

 

what to do to make them enable? can you please tell,what code i might have missed to put while creating the window?

 

Herewith i am sending the screenshot for your referrence. u will get clear idea from it. please check the link. i have given the red marks on the screenshot.uploads/20080809_015437_scrren.zip

 

Thanks And Regards,

I am sorry,But even if i open 4 - 5 documents,the navigators doesnt work.

In fact they are not at all enabled. the close button beside them,is enabled.We can check it also.Like whenever we take the cursor on the close button,it becomes orange background.But these navigators doesnt show any color change.

 

I think i have missed something while creating the ribbon bar.

Can you please help me to trace what i have missed?

Please tell the solution if possible.

 

Thanks And Regards,

Vijay.
