Hi again list, So how about these TreeViews... :-\ I can't figure out how to use one as an efficient view of an internal collection at all. Is there some way I can just interact directly with the objects in the list or the view? Sorry to ask so many newbie questions, but please help again - I'm *this* close to writing my own VBox of clickable Labels! :-)
Thanks to everyone who replied RE threading. One more thing there, do I need to do anything special if I want to access a widget from a timeout callback? I'm still getting the odd crash, and I'm pretty sure the only thread running is the one doing the timeouts. I have other threads running but they are all separated from the GUI either completely or via the timeouts. Sorry for another long email, but here's the background for anyone who wants to reply: I got over the idea of having to keep a reference to the widget as well as the ListStore in order to do the basic operations. That almost made sense, but then it seemed that for something as simple as getting the value of the activated row in the RowActivated handler also requires an TreeIter on the store, and all you have is a Path, not a link to the widget or to the row data. What really bummed me was when I discovered that this iterater refuses to store and retrieve raw objects, complaining about its limited set of types and the fact that my index column data isn't one of them. Alright, ranting aside, how does one usually link the data in the ListStore back to other objects? All I'm trying to do here is operate a simple list of named internal objects that, when double clicked, cause further information to be displayed. I could iterate through my own list using some artifically generated index (which would then be displayed alongside the object's name) in order to link back to my internal objects, but I can't believe that's the way it was intended to be used. I've been through the Gtk API multiple times to no avail, and the SDK sample sucks - there's no interaction or even run-time modification of the list. Did I miss a simple [ ] indexing operator defined somewhere or what?
