Thanks Kevin.
I know of the dispatcher but the problem is that I need to fill a
TreeStore: the data is very complex and hard to send through a dispatcher.
Does anyone know if filing a store that is not bound to any TreeView
would be ok (out of the main thread, I mean)? Is so, I could just swap
the TreeView's store with the new one.
Thanks

I'm not entirely sure of your problem, but I do know that GTK does not
guarantee *any* thread safety for it's components. You should not be
modifying the TreeView outside the UI thread. If this is how GTK
manifests this problem, so be it. There is a Glib::Dispatcher() [1]
[2] which would allow you to spawn the dispatcher in the UI thread,
then push things from a worker thread and make sure the value gets
updated on the UI.
I hope I'm actually helping the problem and not just being critical on
style. :(
Cheers,
Kevin

Hi,
my application fills some TreeStrores and ListStores at runtime
but the data is read from large files and the computation of some
values takes time. Therefore I put a progress bar in a splash
window and fill the store in another thread.
The TreeView fills oddly: once the lines do not fit anymore on the
display, the scollbar is not updated. I tried to add
gdk_threads_entrer() and gdk_threads_leave() before and after the
calls to XXXStore::append() but it did not change anything.
First question: are the stores really thread unsafe? I tend to
consider them as non-UI classes, so TreeView should be the one
handling the thread-safety…
Second question: how do I make sure I do not mess up with the
thread safety when filling my stores?
Thanks a lot,
yann
