Re: Gtk::TreeView: Custom cellrenderer for single cells

["Daniel J. Lauk" <Daniel Lauk Student FH-Reutlingen de>]

Thanks for your answers. I've been pretty busy implementing my own dropdown/combo
box style renderer until now.

I think -- unless I didn't understand a certain part -- that having multiple
renderers is just fine unless I want to fill the list of my drop down renderer
with different items for different cells.

...or am I confusing something? The CellRenderer is used on a column basis,
right? So I'd have to put as many of my renderers inside a single column as
I want different drop down lists and fiddle around with the property_visible,
right?

Sorry, I'm kind of confused about all this. But maybe I'll come up with some
docs afterwards ;-)

Best reagards,
