Sorry to bother you with, which seems to be a simple question, but I am out of ideas.
I am trying to coloring an entire row of a GtkTreeView.After some search I discovered "GTK+ 2.0 Tree View Tutorial" fromTim-Philipp Müller which taught me A LOT about tree views and theparadigm of model-view.Ok, said that, I am now able to paint an entire row, and just the row,with a color of my choice but, the problem is that I am unable to dothat at execution time, just at the compilation time because the columnwhich has to be read for the renderer knows if the color should bedisplayed or not isn't and I do not know why.If I connect the the renderer's property "cell-background-set" to ancolumn and don't connect the "cell-background" property to anothercolumn model I am able to control whenever the background should beprinted or not but, when I connect the "cell-background" to one columnat the model the column with the "cell-background-set" is just forgotten.
I did an example, based on a piece of code that I found, to show thisbehavior.Someone can light me on?Thank you for your time.
PS: Just an off-topic question: I never knows if I am suppose to attachthe code example or put it with along with my e-mail. What is best?
