GtkSheet with freeze panes

I want to add additional functionality to freeze few rows and columns from the beginning of the sheet.

That means if i scroll the freeze panes remains fixed and all the columns and/or rows after that will be scrolling. I could not hack the code for scrolling. If anyone of you have enough time could you please explain me the following three function ?

adjust_scrollbars
hadjustment_changed
hadjustment_value_changed

else could any one help me to implement those functions.

Thanks
John

Re: GtkSheet with freeze panes

these functions for positioning of scrollbars
and signal handlers for horizontal adjustments.
