I usually program java, but because java is some damned slow and eats up to many resources, I began to do some C programming. I know the basics and created some small apps, but now I am working on a my first GTK app. So be nice to this GTK noob ...
I made window with a GtkTreeView (with a GtkListStore and GtkTreeSelection). I am able to add things to it with a dialog box, but now I'd like to make some function to remove the selected entry in the list.
How should I do this? I noticed the function gtk_tree_selection_get_selected_rows which gives me a GList* but what next? I know I can get the selection paths out of it (which should be just one row since I've set the mode on GTK_SELECTION_SINGLE), but how do you remove those paths from the model?
Well... Though I don't remember too well, I have done this before. I think there is a gtk function to remove an item from a tree. Look into the gtk tuts over at www.gtk.org, or try google. If google, do a search for some of the other tree functions, and see if you can find it that way. Keep trying, don't give up, you'll get it.
I know, I won't give up. It really isn't in the API. I don't know much about C and this probably isn't right, but could it be that you just have to free that path and then send a signal to the model (there is a function for that)?
