Hi there

I’m coding an app with visualruby and I love it, but sometimes the lack  
of documentation and knowledge/skills (on my side) gets me stuck. 🙂

What I can’t seem to get past now is to attach some code to  
VR::ComboCol/VR::CellRendererCombo signals? (Or any other signals  
produced by cells in a listview, for that matter?)

Cheers,  
k

Hello Kacper,

I’m glad that your enjoying the use of VisualRuby. As to working with  
Column Renderers, you will need to get the column first, which you can  
do  
by using the ViewCommon method: renderer(:id).

This will return the Actual Renderer for the column that you want to  
modify, or connect a signal to. So, you would do something like this:

tree = VR::TreeView.new(:x =\> String, :y =\> String, :z =\> String)  
tree.renderer(:y).signal\_connect(“editing-started”) do |\*args|  
… do code here …  
end

hth,

Mario
