Port to GObject, can go back in gdk-pixbuf after setting up a 2000-12-16 Havoc Pennington <hp@pobox.com> * gtk/gdk-pixbuf-loader.h, gtk/gdk-pixbuf-loader.c: Port to GObject, can go back in gdk-pixbuf after setting up a gdk-pixbuf-marshal.h header over there. * gtk/gtktreeview.c: s/SEPERATOR/SEPARATOR/g; (gtk_tree_view_class_init): specify GTK_TYPE_ADJUSTMENT for signal args (gtk_tree_view_init): don't unset GTK_NO_WINDOW, it shouldn't be set (gtk_tree_view_realize_buttons): don't gtk_widget_show() buttons here, do it when we create the buttons later (gtk_tree_view_realize_buttons): add some g_return_if_fail (gtk_tree_view_map): paranoia checks that column->button is shown and unmapped (gtk_tree_view_size_request): only request visible children. 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. (Presumably this allows a nice loop with column != NULL as test.) (gtk_tree_view_move_to): document what 0.0, 0.5, 1.0 alignments mean (left/right/center etc.). (gtk_tree_view_collapse_all): only queue a draw if we're mapped (gtk_tree_view_expand_row): add docs (gtk_tree_view_collapse_row): add docs * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_clicked): new function to emit the clicked signal on a column * gdk/gdkevents.c (gdk_event_get_state): new function, to get the state of an event (gdk_event_get_time): don't treat GDK_SCROLL as a button event, remove default case from switch so gcc will whine if we don't explicitly handle all event types * gtk/gtktreeselection.h: added some FIXME * gtk/gtktreeprivate.h (struct _GtkTreeViewPrivate): rename "columns" to "n_columns" and "column" to "columns" for clarity

Add support for animating expanders. 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.

Draw the row backgrounds with draw_flat_box using different detail for even/odd rows. * gtk/gtkrbtree.c, gtkrbtree.h: Keep track of the parity of each row, so we can draw the alternating colors thing * gtk/gtktexttag.c (gtk_text_tag_set_property): if we change a property from a synonym property, notify for the synonym. Also, nuke the background_gdk_set and foreground_gdk_set synonyms (gtk_text_tag_get_property): Always return the font, even if all its fields aren't set * gtk/gtkcellrenderertext.h (struct _GtkCellRendererText): don't store the attr list; it leaves us with no way to change attributes in _render according to the render flags, and no way to implement get_property.

Big TreeView DnD fixage, makes drops on empty models work, makes TreeStore Wed Sep 10 01:06:44 2003 Kristian Rietveld <kris@gtk.org> Big TreeView DnD fixage, makes drops on empty models work, makes TreeStore DnD work and gets rid of gtk-tree-model-drop-append. Related bugs #95362 and #113314. I don't want to touch this code ever again. * gtk/gtktreeprivate.h (GtkTreePrivate): add empty_view_drop field. * gtk/gtktreednd.c (gtk_tree_get_row_drag_data): add check for selection_data->length. * gtk/gtktreeview.c (struct DestRow), (dest_row_free), (set_dest_row), (get_dest_row): we don't store just the row ref anymore, but a struct with the row ref and additional info, (set_destination_row): handle drops on empty space and some style fixes, (get_logical_dest_row): also return path_down_mode/drop_append_mode flags, handle dropping childs on their new parents, rewrite drop append handling into something saner, (gtk_tree_view_drag_motion): show a "drop possible arrow" on empty spaces, (gtk_tree_view_drag_drop): updates for updated backend, (gtk_tree_view_drag_data_received): updates for updated backend, path down mode (treestore DnD) handling, (gtk_tree_view_set_drag_dest_row): set empty_view_drop flag, when we are trying to drop a row on an empty model, (gtk_tree_view_get_drag_dest_row): handle empty_view_drop flag. * gtk/gtkliststore.c (gtk_list_store_drag_data_received), (gtk_list_store_row_drop_possible): style and drop-append fixes. * gtk/gtktreestore.c (gtk_tree_store_drag_data_received): ditto.
