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
