2001-07-22 Anders Carlsson <andersca@gnome.org> * gtk/gtktreeview.c (gtk_tree_view_class_init): Replace the expander_height and expander_width properties with a single property, expander_size. (gtk_tree_view_init): Set the tab_offset to expander_size plus some padding. (gtk_tree_view_unrealize): Remove the expand/collapse timeout if it exists. (coords_are_over_arrow): Fix a small bug. (gtk_tree_view_motion_draw_column_motion_arrow): Use expander_size. (gtk_tree_view_draw_focus): Use "treeview" instead of "add-mode" as detail when drawing the focus. (gtk_tree_view_bin_expose): Use "treeview-drop-indicator" instead of "add-mode" as detail when drawing the focus. (gtk_tree_view_deleted): If we have a node currently being expanded or collapsed, remove the timeout and set the node to NULL. (gtk_tree_view_queue_draw_arrow): New function that just redraws the arrow of a node. (gtk_tree_view_draw_arrow): Use expander_size instead of expander_width/expander_height, also pass a different expander_style to gtk_paint_expander depending on the state of the node being drawn. (expand_collapse_timeout): New function for expanding or collapsing a node depending on the previous state. (gtk_tree_view_real_expand_row): Add timeout and set correct state for node being expanded. (gtk_tree_view_real_collapse_row): Add timeout and set correct state for node being collapsed. * gtk/gtktreeprivate.h (struct _GtkTreeViewPrivate): Add information about the node currently being expanded or collapsed, and also a timeout id. * gtk/gtkstyle.h (struct _GtkStyleClass): Replace is_open with expander_style for draw_expander. * gtk/gtkstyle.c (gtk_draw_expander): Replace is_open with expander_style. (create_expander_affine): New function for creating an expander affine. (apply_affine_on_point): New function for applying an affine to a point. (gtk_default_draw_expander): Modified to take expander_style instead of is_open, and to draw the rectangle rotated differently depending on the expander style. (gtk_paint_expander): Replace is_open with expander_style. * gtk/gtkrbtree.h: Add expander states to GtkRBNodeColor. * gtk/gtkenums.h: Add expander style enum.
