Re: turn on italics in TextView

2017-06-20 Thread Eric Cashon via gtk-app-devel-list 

 
On that last post, I think that I have some bad pointer arithmetic. Moving a 
pointer past the end and freeing a moved pointer. Not so good.

Eric

...
GSList *tlist=NULL;
GSList *p=NULL;
GSList *next=NULL;
tlist=gtk_text_iter_get_tags();
p=tlist;
if(tlist!=NULL)
  {
do
  {
next=p->next;
gchar *string=NULL;
g_object_get(G_OBJECT(p->data), "name", , NULL);
g_print("%s\n", string);
g_free(string);
if(next!=NULL)p=g_slist_next(p);
  }while(next!=NULL);
   }
else g_print("No Tag\n");

if(tlist!=NULL) g_slist_free(tlist);
...

Another option is to look at the properties of the tags to get the information 
that you need. This might work better than saving globals and matching pointers.

Re: Find path under mouse

2017-06-20 Thread Anthony Ruth 
If I understand correctly, you want to get the x and y value of the mouse
at the time when the keyboard event happens. You can either use
GdkDeviceManager to get the pointer and then get x and y from that, or
listen for motion_notify events on your treeview and keep track of x and y
values (I think this may be what you mean by path).
