I came up with a solution. I changed the GtkCellRendererText to a GtkCellRendererCombo. I didn't add any items to the combo or even set the model of the combo; the only property I set was the "editable" property to true. This created exactly the functionality I was looking for. The user can't even tell that the cell renderer is a combo box, because it has nothing in it. Clicking on the combo does not toggle the GtkCellRendererToggle. I suppose this is because GTK no longer considers the column one activatable entity.
