Perhaps it takes 2 iterations of the main loop for the vscale to update.
What happens if you try
while(gtk_events_pending()) gtk_main_iteration();
instead?

I assume the unrecognised pragma will be ignored by every other compiler
out there so it should be portable (if a little

at least scales the image, but only to a preset size and obviously not
with the size of the button

If I set a button to have an image like this:
gtk_button_set_image(GTK_BUTTON(button),gtk_image_new_from_file(fname.svg));
then the button grows to the full size of the image (huge). Using:
gtk_widget_set_size_request(button,30,30);
I can make the button have a sensible size, but the

I usually do for std::vector (although the performance of deleting from
the middle of a vector is obviously not good)

All in all not the prettiest code, but at least it works.
If there is a neater solution I would be happy to hear about it

splash is a local variable.

What do you exactly expect from gtk_tree_view_get_visible_range()
when the tree view is not realized, has no size allocated,
etc. (beside a more helpful error message)? What is
*visible* then?
I probably expect FALSE again but I suppose the current behaviour is OK

My previous email on this subject was rubbish and unspecific, sorry for
the spam. So - I have reduced my code down to the smallest test case and
now hope someone can help me.
#include gtk/gtk.h
int main(int argc, char **argv)
{
gtk_init(argc, argv);
//make a store and view
So - I have a treeview, initially empty. I am using the code below as
part of a function to find out what items are visible. Once any items
are added to the list it goes bad (usually - sometimes it works fine)

You are both right - it now works fine. Thanks for pointing out what was
