c# - Setting a NodeView to reflect the changes in the ListStore Model -

using mono, monodevelop, c# , gtk# on linux.

i know has been asked before, no matter try, none of examples or answers seem work me. still can't changes in liststore reflected in treeview.

i start of so....

liststore ls_nvdevicefiledescription = new liststore (typeof(string), typeof(string), typeof(string)); liststore ls_dev_sensor_codes = new liststore (typeof(string)); liststore ls_dev_sensor_value_types = new liststore (typeof(string)); 

the first liststore treeview, second , third cellrenderercombo's on column 1 , 3 of treeview.

i add values cellrenderercombo's user pick values from....

string[] _codes = csql.csql_getdevicesensorcodes (); string[] _types = csql.csql_getdevicesensorvaluetypes ();          // codes.         if (_codes != null) {             (int = 0; < _codes.length; i++) {                 ls_dev_sensor_codes.appendvalues (_codes [i]);             }         }          //do types         if (_types != null) {             (int = 0; < _types.length; i++) {                 ls_dev_sensor_value_types.appendvalues (_types [i]);             }         } 

i bind liststore they're appropriate 2 cellrenderers....

dev_sensor_codes.model = ls_dev_sensor_codes; dev_sensor_codes.textcolumn = 0;  dev_sensor_value_types.model = ls_dev_sensor_value_types; dev_sensor_value_types.textcolumn = 0; 

and of course pack them onto they're respective columns....

col_sensor_code.packstart (dev_sensor_codes, true); col_sensor_descr.packstart (dev_sensor_descr, true); col_sensor_value_type.packstart (dev_sensor_value_types, true); 

i bind liststore treeview , append columns....

nvdevicefiledescr.model = ls_nvdevicefiledescription;  nvdevicefiledescr.appendcolumn (col_sensor_code); nvdevicefiledescr.appendcolumn (col_sensor_descr); nvdevicefiledescr.appendcolumn (col_sensor_value_type); 

i use following code append row treeview (the change reflected).

liststore store = (liststore)nvdevicefiledescr.model; treeiter iter = store.append (); treepath path = store.getpath (iter); nvdevicefiledescr.setcursor (path, nvdevicefiledescr.columns[0], true); 

now, i'll give 2 examples of edited events i'm sure should work, doesn't....

example 1:

dev_sensor_codes.edited += delegate(object o, editedargs args)  {   liststore store = (liststore)nvdevicefiledescr.model;   treeselection sel = nvdevicefiledescr.selection;   treeiter iter;      if (!sel.getselected (out iter)) {       return;     }      store.setvalue(iter, 1, args.newtext); }; 

example 2:

dev_sensor_value_types.edited += delegate(object o, editedargs args)  {   liststore store = (liststore)nvdevicefiledescr.model;   treeiter iter;   store.getiterfromstring(out iter, args.path);   store.setvalue (iter, 2, args.newtext); }; 

in both examples know i'm using iter, because gtk has habit of letting know if have stale iter (i think?), , treepath, must it's passed through edited args.

i can verify right iters, paths , values printing stdout, can't changes in liststore treeview reflected in treeview.

the change show, when programatically appendvalues, or append. add new line in treeview, no values ever show up.

many, many hand.

==========================================

solution

so, case, answer our own questions because neglect read our own code right?

i've left out crucial step in whole thing above , binding cellrenderers actual columns. 'looked' did, didn't, here goes....

i packed cellrenderers in columns following....

column.packstart (cellrenderer, bool);  //or in case col_sensor_code.packstart (dev_sensor_codes, true); 

this fine, need bind cellrenderer column (or other column actually) so......

column.addattribute (cellrenderer, attribute, column index);  // in case instance.... col_sensor_code.addattribute (dev_sensor_codes, "text", 0); 

so, many time , hope helps other blind fool ;)
