Event triggering with primitives

[Catherine Dunn <cldunn MIT EDU>]

Hello,

I am new to GTK. I am trying to create an application with several primitives
drawn in a drawing area. I would like certain events to occur whenever the user
clicks on/rolls over the primitives, but I am having trouble doing this since
the primitive functions return void not GtkWidget. I'd appreciate some advice.

Thanks,
