【问题描述】：
我制作了一个以树库为模型的树视图。该窗口按预期显示，但是当我单击“+”以展开项目时，我收到以下消息：
GLib-CRITICAL **: Source ID 221 was not found when attempting to remove it
这是我的代码：
#include <gtk/gtk.h>
/* compile with: */
/* gcc main.c -o boxy `pkg-config --cflags --libs gtk+-2.0` */
typedef struct {
GtkWidget *toplevel;
GtkWidget *treeview;
} Widgets;
enum { ITEM_PARENT, ITEM_CHILD };
typedef struct {
gint tipo;
gint id;
gchar *nombre;
gint cantidad;
} Lista;
void addColumn (GtkTreeView *tv, const gchar* title, gint pos) {
GtkCellRenderer *tmp;
tmp = gtk_cell_renderer_text_new ();
g_object_set (tmp, "editable", TRUE, "editable-set", TRUE, NULL);
gtk_tree_view_insert_column_with_attributes (tv, -1, title, tmp, "text", pos, NULL);
}
void setupTree (GtkTreeView *tv) {
const Lista lista[] = {
{ITEM_PARENT, 125, "Superman", 2},
{ITEM_CHILD, 23, "Batman", 1},
{ITEM_CHILD, 7, "Hulk", 5},
{ITEM_PARENT, 65, "Iron Man", 2},
{-1, -1, NULL, -1}
};
GtkTreeStore *model;
GtkTreeIter last;
gint pos;
model = gtk_tree_store_new (3, G_TYPE_INT, G_TYPE_STRING, G_TYPE_INT);
addColumn (tv, "ID", 0);
addColumn (tv, "Nombre", 1);
addColumn (tv, "Cantidad", 2);
for (pos = 0; lista[pos].tipo != -1; pos++) {
GtkTreeIter iter;
if (lista[pos].tipo == ITEM_PARENT) {
gtk_tree_store_append (model, &iter, NULL);
last = iter;
} else if (lista[pos].tipo == ITEM_CHILD) {
gtk_tree_store_append (model, &iter, &last);
}
gtk_tree_store_set (model, &iter, 0, lista[pos].id, 1, lista[pos].nombre, 2, lista[pos].cantidad, -1);
}
gtk_tree_view_set_model (tv, GTK_TREE_MODEL (model));
g_object_unref (model);
}
int main (int argc, char *argv[]) {
Widgets *ptr;
GtkWidget *scroll;
gtk_init (&argc, &argv);
ptr = g_slice_new0(Widgets);
ptr->toplevel = gtk_window_new (GTK_WINDOW_TOPLEVEL);
scroll = gtk_scrolled_window_new (NULL, NULL);
gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW (scroll), GTK_POLICY_AUTOMATIC, GTK_POLICY_AUTOMATIC);
gtk_scrolled_window_set_shadow_type (GTK_SCROLLED_WINDOW (scroll), GTK_SHADOW_OUT);
ptr->treeview = gtk_tree_view_new ();
setupTree (GTK_TREE_VIEW (ptr->treeview));
g_signal_connect (ptr->toplevel, "destroy", G_CALLBACK (gtk_main_quit), NULL);
gtk_container_set_border_width (GTK_CONTAINER (ptr->toplevel), 10);
gtk_container_add (GTK_CONTAINER (scroll), ptr->treeview);
gtk_container_add (GTK_CONTAINER (ptr->toplevel), scroll);
gtk_widget_show_all (ptr->toplevel);
gtk_main ();
g_slice_free (Widgets, ptr);
return 0;
}
有什么想法吗？
【问题讨论】：
-
您尝试过使用 gdb 吗？追踪？编辑：刚刚运行它，我确实 not 收到任何警告或错误。 gtk+-2.0 是 2.24.22，在 Fedora 20 x86_64 上
-
我也没有收到任何警告。您确定问题实际上可以通过问题中的代码重现吗？
-
是的，这是漏洞代码，运行gdb后，显示相同的错误，并且使用“where”命令返回“no stack”；我正在使用带有 gtk+-2.0 2.24.23-1 的 Archlinux :(
-
用
-ggdb编译它，崩溃后使用bt。发布 complete 回溯。 -
我使用 ddd，这来自回溯窗口：postimg.org/image/rfv1nl66l
