 Posted: Fri Aug 07, 2009 9:53 am Post subject: TreeStore.getValueInt returns weird values |
 |
|
Hello again,
After expanding a bit my previous code, I am having a weird issue.
My interface includes a TreeView (defined in XML), linked to a TreeStore (defined in code).
I am having no problems populating the tree with some data from a database.
There's a callback called 'OnRowActivated', which needs to retrieve some code from the TreeStore: an int (not showed in the TreeView) and a string (which is). The string comes along nicely, not so the int. Instead of values 0, 1, ... it returns values -1210499296, -1210515264, ...
Here is the code:
| Code: |
class XMLApp {
Generic db;
Builder app;
this(char[][] args, Generic db) {
this.db = db;
Main.init(args);
app = new Builder();
auto err = app.addFromFile("Interface.xml");
if(err == 0 ) {
Stderr("Error opening glade file.").newline;
}
app.connectSignals(null);
this.initTree();
auto obj = app.getObject("window");
obj.setData("GObject", null);
auto w = new Window(cast(GtkWindow*)obj.getObjectGStruct());
if(w !is null) {
w.show();
w.addOnHide( delegate void(Widget aux){ Main.exit(0); } );
Main.run();
}
else { Stderr("Error launching application.").newline; }
}
void initTree() {
auto obj = app.getObject("sideTreeView");
obj.setData("GObject", null);
auto treeview = new TreeView(cast(GtkTreeView*)obj.getObjectGStruct());
GType[2] columns = [GType.INT, GType.STRING];
auto tree = new TreeStore(columns);
TreeIter[char[]] parent;
auto tables = db.get_tables();
foreach(table; tables) {
//Add the table as a root node
parent[table.get_name()] = tree.append(null);
auto iter = parent[table.get_name()];
insert_value(tree, iter, table);
//Add contents of the table too
auto values = db.get_names(table);
foreach(value; values) {
auto subiter = tree.append(iter);
insert_value(tree, subiter, value);
}
}
treeview.addOnRowActivated(&tree_selected);
treeview.setModel(tree);
}
void tree_selected(TreePath path, TreeViewColumn col, TreeView treeview) {
TreeIter iter = new TreeIter();;
auto tree = treeview.getModel();
tree.getIter(iter, path);
auto parent = iter.getParent();
auto parent_name = tree.getValueString(parent, 1);
switch(parent_name) {
case "notes":
auto id = tree.getValueInt(iter, 0);
auto content = db.get_note(new Element(id, "", null));
Stdout(id)(content).newline;
break;
case "sheet":
auto id = tree.getValueInt(iter, 0);
auto name = tree.getValueString(iter, 1);
Stdout("You clicked on:")(id)(name).newline;
break;
default: break;
}
return true;
}
void insert_value(TreeStore tree, TreeIter iter, Element elt) {
auto id = elt.get_id();
auto name = elt.get_name();
tree.setValue(iter, 0, id);
tree.setValue(iter, 1, name);
}
}

It looks like it should be working. I'll see if i can find out whats messing things up this weekend.
I'm assuming elt.get_id does indeed return the 0, 1, ... you are trying to retrieve. |

| Yes, sorry. I should have mentioned: get_id() returns the id key of the element in a database, starting at 0 and incrementing. It's double checked working. |
