Re: Set background color into a Gtk::Treeview row

[Bernd Robertz <bernd robertz cssweb de>]

Hello Filipe,

I'm not sure that I have understand what you want to do.

If I got your point, you can define the wanted color in an hidden column
and set the color to the default color. Than you can implement the cell
renderer with the background color properties in your constructor and
add them to the view.

So when the user clicks on a row, you can as usual derefence the row and
set the hidden color column to the desired color. Than only the row wich
was clicked, has the new color because all other hidden column colors
are not touched.

If the user clicks on an other row, you can set the color back to your
standart color (wich is IMO normaly white).

In a db app, wich I wrote, I wanted to set every second row in an other
color.
So I implemented an own cell renderer with background properties. When I
fill My treeview, I set every second row with another color. In My app
it is quite useless, but I wanted to know how it works.

Bernd
