From 422046cc58a534f6916205f282cc6b50a98eeb95 Mon Sep 17 00:00:00 2001 From: Chris Toshok Date: Fri, 23 Jun 2000 07:47:37 +0000 Subject: add icon_at virtual function - it was stupid to make the insert call take 2000-06-23 Chris Toshok * e-tree-model.h, e-tree-model.c: add icon_at virtual function - it was stupid to make the insert call take 2 pixbufs. the model should give this information. * e-cell-tree.c: get rid of the opened/closed pixbuf stuff. call e_tree_model_icon_of_node. * e-tree-example-1.c: add my_icon_at. * e-tree-simple.c (simple_icon_at): new function (e_tree_simple_new): add icon_at parameter. * e-tree-simple.h: add SimpleIconAtFn. svn path=/trunk/; revision=3707 --- widgets/table/e-cell-tree.c | 5 +---- widgets/table/e-tree-example-1.c | 19 +++++++++++----- widgets/table/e-tree-model.c | 48 +++++++++++++--------------------------- widgets/table/e-tree-model.h | 8 +++---- widgets/table/e-tree-simple.c | 13 ++++++++++- widgets/table/e-tree-simple.h | 11 +++++---- 6 files changed, 52 insertions(+), 52 deletions(-) (limited to 'widgets/table') diff --git a/widgets/table/e-cell-tree.c b/widgets/table/e-cell-tree.c index 61c86fad2d..2d1a006fdb 100644 --- a/widgets/table/e-cell-tree.c +++ b/widgets/table/e-cell-tree.c @@ -178,10 +178,7 @@ ect_draw (ECellView *ecell_view, GdkDrawable *drawable, expanded = e_tree_model_node_is_expanded (tree_model, node); subcell_offset = offset; - if (expanded) - node_image = e_tree_model_node_get_opened_pixbuf (tree_model, node); - else - node_image = e_tree_model_node_get_closed_pixbuf (tree_model, node); + node_image = e_tree_model_icon_of_node (tree_model, node); if (node_image) { node_image_width = gdk_pixbuf_get_width (node_image); diff --git a/widgets/table/e-tree-example-1.c b/widgets/table/e-tree-example-1.c index c506faebd5..c98e53c7af 100644 --- a/widgets/table/e-tree-example-1.c +++ b/widgets/table/e-tree-example-1.c @@ -83,6 +83,15 @@ my_value_at (ETreeModel *etm, ETreePath *path, int col, void *model_data) } } +static GdkPixbuf * +my_icon_at (ETreeModel *etm, ETreePath *path, void *model_data) +{ + if (e_tree_model_node_is_expanded (etm, path)) + return tree_expanded_pixbuf; + else + return tree_unexpanded_pixbuf; +} + /* This function sets the value at a particular point in our ETreeModel. */ static void my_set_value_at (ETreeModel *etm, ETreePath *path, int col, const void *val, void *model_data) @@ -130,7 +139,6 @@ add_sibling (GtkButton *button, gpointer data) e_tree_model_node_insert_before (e_tree_model, parent_node, selected_node, - NULL, NULL, g_strdup("User added sibling")); } @@ -150,7 +158,7 @@ add_child (GtkButton *button, gpointer data) g_assert (selected_node); e_tree_model_node_insert (e_tree_model, selected_node, - 0, NULL, NULL, + 0, g_strdup("User added child")); } @@ -238,25 +246,24 @@ create_tree (void) /* here we create our model.
