* SECTION:gtktreeselection
* @Short_description: The selection object for GtkTreeView
* @Title: GtkTreeSelection
* @See_also: #GtkTreeView, #GtkTreeViewColumn, #GtkTreeDnd, #GtkTreeMode,
* #GtkTreeSortable, #GtkTreeModelSort, #GtkListStore, #GtkTreeStore,
* #GtkCellRenderer, #GtkCellEditable, #GtkCellRendererPixbuf,
* #GtkCellRendererText, #GtkCellRendererToggle
*
* The #GtkTreeSelection object is a helper object to manage the selection
* for a #GtkTreeView widget. The #GtkTreeSelection object is
* automatically created when a new #GtkTreeView widget is created, and
* cannot exist independentally of this widget. The primary reason the
* #GtkTreeSelection objects exists is for cleanliness of code and API.
* That is, there is no conceptual reason all these functions could not be
* methods on the #GtkTreeView widget instead of a separate function.
*
* The #GtkTreeSelection object is gotten from a #GtkTreeView by calling
* gtk_tree_view_get_selection(). It can be manipulated to check the
* selection status of the tree, as well as select and deselect individual
* rows. Selection is done completely view side. As a result, multiple
* views of the same model can have completely different selections.
* Additionally, you cannot change the selection of a row on the model that
* is not currently displayed by the view without expanding its parents
* first.
*
* One of the important things to remember when monitoring the selection of
* a view is that the #GtkTreeSelection::changed signal is mostly a hint.
2012-12-12 02:30:22 +00:00
* That is, it may only emit one signal when a range of rows is selected.
* Additionally, it may on occasion emit a #GtkTreeSelection::changed signal
* when nothing has happened (mostly as a result of programmers calling
* select_row on an already selected row).

Also, check for realization before hiding/showing the tree_column->window; if this window could exist before realization, then it's busted and needs fixing, we can't create GDK resources pre-realization.

Fix #139290: 2004-07-08 Federico Mena Quintero <federico@ximian.com> Fix #139290: * gtk/gtkfilesystemmodel.c (_gtk_file_system_model_new): Add a GError argument. Do check for errors when getting the GtkFileFolder: get the folder and read the children before actually creating the model. Removed obsolete code that handled roots-changed on the file system. (file_model_node_get_info): Assert that we don't reach the old case to display file system roots. (roots_changed_callback): Removed. * gtk/gtkfilechooserdefault.c (set_list_model): Add a GError argument, and a boolean return value. Return an error if we cannot create the file system model. On error, set a NULL model on the tree. (gtk_file_chooser_default_set_current_folder): Use the error value from set_list_model(). (gtk_file_chooser_default_set_property): Set the show_hidden property only if the browse_files_model exists. (gtk_file_chooser_default_unselect_path): Only operate if the browse_files_model exists. (check_preview_change): Check whether we have the sort_model. (change_folder_and_display_error): Copy the path we get passed before using it. There's a comment in there that explains why we need to copy it; basically, if the passed path belongs to the model, the model may go away in the middle of this function and we'll be left with a dangling pointer. (install_list_model_filter): Assert that the model is not NULL. (set_current_filter): Check whether the model exists. * gtk/gtktreeselection.c (gtk_tree_selection_get_selected): Don't g_return_if_fail if the model is NULL. (gtk_tree_selection_get_selected_rows): Likewise. (gtk_tree_selection_count_selected_rows): Likewise. (gtk_tree_selection_selected_foreach): Likewise. (gtk_tree_selection_path_is_selected): Likewise; rather just return FALSE. (gtk_tree_selection_select_all): Likewise. (gtk_tree_selection_unselect_all): Likewise. (gtk_tree_selection_select_range): Do g_return_if_fail() if the model is NULL. (gtk_tree_selection_unselect_range): Likewise. * gtk/gtkfilesystemunix.c (fill_in_names): Return immediately if g_dir_open() fails: there is no need to set the error ourselves, as g_dir_open() already does it.

Instead store all the specific text attributes. Separate whether an attribute is enabled from its value. Sync all properties with GtkTextTag, make them all consistent, etc. * gtk/gtkcellrenderer.h: Add a flag GTK_CELL_RENDERER_SORTED so renderers can highlight the sort row/column * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_get_property): use accessor functions to get values; this has the side effect of showing up which accessor functions were missing. Added those. * gtk/gtktreeviewcolumn.h: Replace set_justification with set_alignment, to be consistent with GtkLabel, GtkMisc * gtk/gtktreeviewcolumn.c: Added code to display sort indicator arrow. * gtk/Makefile.am (gtk_public_h_sources): add gtktreesortable.h * gtk/gtktreesortable.h: updates in here
