[Evolution-hackers] on deleting folder

[Bill Zhu <bill zhu sun com>]

Dear sir:

In the current evolution version, when I delete a folder, the folder
will be deleted with out detecting if there is any opened mail in this
folder.

I am dealing with this. So I am wondering how can I know if there is a
opened mail in the folder? I cann't find any function or variable can
give me information of this.

Could you give me some help?
