Hi there, I have a treeview and what I'd like to achieve is that the first row of the treeview (under the column headers) be fixed at its place so the scrolling won't affect it. I would use this very first row to filter the treeview. Attached an image showing the what I would like to make. (As you can see there's a row under the column headers including comboboxes)
I was able to access the column headers' buttons. (TreeViewColumn) The TreeViewColumn has a function called set_widget, and I can set any widget _inside_ that button, but it is not good for me, because if I set a combobox with this, than - since it is inside the button - it acts like a button too. I also tried to replace that button with a vbox (and put the button and a combobox in the vbox) but as soon as I removed the button from the treeview, it complaind about propagating expose cannot be done ( g_assert (child->parent == GTK_WIDGET (container));) I think this is because this button is a private child of the treeview, so it won't let me replace it with any other widget. Is there any other way to achieve this? Any suggestions are welcome. Thx. Balazs
