Re: Key-value file parser, howto get all groups and create loop from them

[rupert <rupertt gmail com>]

I've gone through all the warning and now only get one warning on my +- 700
lines of code, now i have 3 warnings left wich I dont get away by now. Thx
for the advice to
go thorugh them, my old teacher told me we can ignore them :(.
I packed the tree into a struct and now access the parts with treedata.iter.
But when i start the programm it seems there is a problem with the iterator
in the function(works fine in the main programm).

this is my struct(which will be scalled down wen the rest works)

static struct treedata {
           GtkListStore *store;
           GtkWidget *tree;
           GtkTreeIter   iter;
           GtkTreeSelection *select;
           GtkCellRenderer *renderer;
           GtkCellRenderer *pixrender;
           GtkTreeViewColumn *column_init;
           GtkTreeViewColumn *column_mount;
           GtkTreeViewColumn *column_device;
           GtkTreeViewColumn *column_name;
           GtkTreeViewColumn *column_mountpoint;
           GtkTreeViewColumn *column_passkey;
           GdkPixbuf    *pixbuf_mapper_yes;
           GdkPixbuf    *pixbuf_mapper_no;
           GdkPixbuf    *pixbuf_mount_yes;
           GdkPixbuf    *pixbuf_mount_no;
           GdkPixbuf *pixbuf_mapper;
           GdkPixbuf *pixbuf_mount;
           GdkPixbuf *pixbuf;
            }treedata;

the function which should updat the image in the treeview:

void crypto_mount_set_pixbuf(struct treedata *treedata){

   GtkTreeIter iter = treedata->iter;
   //GtkTreeModel *store = treedata->store;

   g_print("test");

/*change DATEN into a variable loop which extracts all the rows*/
   if(crypto_mount_check("DATEN"))
   {
       treedata->pixbuf_mount = gdk_pixbuf_new_from_file("pics/mount.png",
NULL);
       gtk_list_store_set(treedata->store, &iter, MOUNT_COLUMN,
treedata->pixbuf_mount, -1);
       g_object_unref(treedata->pixbuf_mount);

   }else{

       treedata->pixbuf_mount =
gdk_pixbuf_new_from_file("pics/unmount.png", NULL);
       gtk_list_store_set(treedata->store, &iter, MOUNT_COLUMN,
treedata->pixbuf_mount, -1);
       g_object_unref(treedata->pixbuf_mount);
   }
   return;
}

and the timeout

g_timeout_add(100, crypto_mount_set_pixbuf, &treedata);

Strangely the function seems to stop, because i only get 1 test on the bash:
(cryptomaster:11056): Gtk-CRITICAL **: gtk_list_store_set: assertion
`iter->stamp == list_store->stamp' failed


I have split my project into different files, if its neccesary i could
append an tarball
to my mails, if its better for you to see a solution to my problems.

greetings
