I'm creating a messaging application to replace the one already installed on my phone, which will give me some added features that I need.
The initial idea is to use a table to store all intercepted messages with an extra column added to signify whether the message is new or has already been read.
I'd like to use the tree view to show each message i.e.- each column of the table.
So far I'm making good progress, but is it possible to define different images for node1?
I'd like to display an icon to indicate if the message has been read or not, just like already done in most phones.

From the examples and help file it does not look possible, but is there a work-a-round that I could use?

Thanks,
