Move header size calculation in here, for cleanliness, and to maintain invariants for child widgets if we eventually let users set different children inside the buttons (gtk_tree_view_map_buttons): factor out code to map buttons, since it was being called several times (gtk_tree_view_size_allocate_buttons): move_resize the drag windows instead of just moving them; their height may change if we allow random widgets in there, or the theme changes. (gtk_tree_view_size_allocate): move button size allocation above emitting the scroll signals, to ensure a sane state when we hit user code (gtk_tree_view_button_release): remove queue_resize after tree_view_set_size(), set_size() will handle any resize queuing that's needed (gtk_tree_view_focus_in): just queue a draw, don't fool with draw_focus goo (gtk_tree_view_focus): use gtk_get_current_event() and gdk_event_get_state() (gtk_tree_view_deleted): don't queue_resize() after calling set_size() (gtk_tree_view_build_tree): fix a "if (foo); {}" bug - i.e. remove semicolon (gtk_tree_view_create_button): show the button here (gtk_tree_view_button_clicked): actually emit the clicked signal on the column (_gtk_tree_view_set_size): return right away if the size is unchanged, as a cheesy optimization (gtk_tree_view_setup_model): rename set_model_realized to setup_model to match the flag that indicates whether we've called it (gtk_tree_view_get_hadjustment): create adjustment if it doesn't exist, because set_scroll_adjustment does that and it shouldn't matter what order you call these in (gtk_tree_view_get_vadjustment): ditto (gtk_tree_view_set_headers_visible): canonicalize the bool, for paranoia (gtk_tree_view_set_headers_visible): call gtk_tree_view_map_buttons() instead of using cut-and-paste code (gtk_tree_view_append_column): clarify whether the return value is the count of columns before or after, and do the increment separately from the return statement so you can tell from the code. (gtk_tree_view_remove_column): ditto (gtk_tree_view_insert_column): ditto (gtk_tree_view_get_column): remove g_return_if_fail for columns outside the existing range, the docs say that outside-range columns are allowed, so we handle them as documented.
