[Gtk-sharp-list] Arbitrary number of columns in Gtk.ListStore

[Xavier de Blas]

Hello Arthur

If i understood what you ask, i do something similar with a TreeStore

I do it like this:


public TreeViewEvent (Gtk.TreeView treeview, int newPrefsDigitsNumber)
{
        /*
        ...
        */
        //sample for 4 columns

        string [] columnsString = { "firstCol", "secondCol", "thirdCol", "fourthCol" };

        store = getStore(columnsString.Length);
        treeview.Model = store;
        prepareHeaders(columnsString);
}



protected TreeStore getStore (int columns)
{
        //prepares the TreeStore for required columns
        Type [] types = new Type [columns];
        for (int i=0; i < columns; i++) {
                types[i] = typeof (string);
        }
        TreeStore myStore = new TreeStore(types);
        return myStore;
}
        
protected virtual void prepareHeaders(string [] columnsString) 
{
        treeview.HeadersVisible=true;
        int i=0;
        foreach(string myCol in columnsString) {
                treeview.AppendColumn (myCol, new CellRendererText(), "text", i++);
        }
}


This code is adapted from here:
