Hi,
this should do something similar to what you are looking for:
static void list_edited(GtkCellRendererText * cell, gchar * path_string, gchar
* new_text, gpointer user_data)
{
GtkTreeView *treeview = (GtkTreeView *)user_data;
GtkTreeModel *model;
GtkTreeIter iter;
guint column;
/* Column number is passed as renderer object data */
gpointer columnptr = g_object_get_data(G_OBJECT(cell), "column");
column = GPOINTER_TO_UINT(columnptr);
/* Get the iterator */
model = gtk_tree_view_get_model(treeview);
gtk_tree_model_get_iter_from_string(model, &iter, path_string);
/* Update the model */
gtk_list_store_set(GTK_LIST_STORE(model), &iter, column, new_text, -1);
}
static void text_editing_started (GtkCellRenderer ATTRIBUTE_UNUSED *cell,
GtkCellEditable *editable,
const gchar *path, GCallback data)
{
debug_err_msg("%s: started", __FUNCTION__);
if (GTK_IS_ENTRY (editable)) {
GtkEntry *entry = GTK_ENTRY (editable);
GCallback cb_func = data;
g_signal_connect(GTK_OBJECT(entry), "activate",
(GCallback)cb_func, (char *)xstrdup(path));
}
}
GtkWidget *string_list_create(int num, GtkSignalFunc func, int show_hide, int
editable,...)
{
GtkCellRenderer *renderer;
GtkTreeViewColumn *column;
GtkListStore *store;
GtkWidget *tree;
GtkTreeSelection *selection;
GType *types;
va_list titles;
int i;
char *tmp;
char *label;
double align;
types = (GType *) malloc((num + 1) * sizeof(GType));
for (i = 0; i < num; i++) {
types[i] = G_TYPE_STRING;
}
store = gtk_list_store_newv(num, types);
xfree(&types);
tree = gtk_tree_view_new_with_model(GTK_TREE_MODEL(store));
gtk_tree_view_set_rules_hint(GTK_TREE_VIEW(tree), TRUE);
/* Setup the selection handler */
selection = gtk_tree_view_get_selection(GTK_TREE_VIEW(tree));
gtk_tree_selection_set_mode(selection, GTK_SELECTION_SINGLE);
if (func) {
g_signal_connect(selection, "changed", G_CALLBACK(func), NULL);
}
/* The view now holds a reference. We can get rid of our own reference
*/
g_object_unref(G_OBJECT(store));
va_start(titles, editable);
for (i = 0; i < num; i++) {
/* Create a cell renderer */
renderer = gtk_cell_renderer_text_new();
tmp = va_arg(titles, char *);
align = va_arg(titles, double);
if (editable == EDITABLE || (editable == CUSTOM &&
va_arg(titles, int) == EDITABLE)) {
g_object_set(renderer,"editable", TRUE, NULL);
g_object_set_data(G_OBJECT(renderer), "column",
GUINT_TO_POINTER(i));
g_signal_connect(GTK_OBJECT(renderer), "edited",
GTK_SIGNAL_FUNC(list_edited), tree);
if (editable == CUSTOM) {
g_signal_connect(GTK_OBJECT(renderer),
"editing-started", GTK_SIGNAL_FUNC(text_editing_started),
(gpointer) va_arg(titles, void*));
}
}
if (!tmp || show_hide == HIDE ) tmp = "";
if (g_utf8_validate(tmp, -1, NULL) != TRUE) {
label = g_locale_to_utf8(tmp , -1, NULL, NULL, NULL);
/* Create a column, associating the "text" attribute of
the cell_renderer to the column of the model */
column =
gtk_tree_view_column_new_with_attributes(label, renderer, "text", i, NULL);
xfree(&label);
} else {
column = gtk_tree_view_column_new_with_attributes(tmp,
renderer, "text", i, NULL);
}
g_object_set (renderer,"xalign", align, NULL);
/* Add the column to the view. */
gtk_tree_view_append_column(GTK_TREE_VIEW(tree), column);
}
va_end(titles);
return tree;
}
Ciao,
Tito
PS.: Hope it helps, cannot post an example at the moment 'cause i'm in a hurry.
If you need, ask and i'll post it later.
