Re: How to draw a custom border across multiple cells in TreeView?

[Stefan Kost <ensonic hora-obscura de>]

Hi Nickolai,

the TreeView has no selectionmmechanism that is that flexible. Two suggestions:
1.) use GtkSheet from gtk-extra-2 (its a spreadsheet widget)
2.) sub-class the treeview and override the expose-method. in the overridden 
expose call parents-expose and the just draw your stuff over it.
