when the user presses a button, i'm calling a dialogbox which has treeview
attached. whenever i call a procedure the application exits with no errors:
using Gtk;
using System;
using System.Windows.Forms;
namespace rakPhotography
{
public partial class DialogTypeOfPrintEdit : Dialog
{
public class typeOfPrint
{
public typeOfPrint(string name, string active)
{
this.Name = name;
this.Active = active;
}
public string Name;
public string Active;
}
private ListStore store;
protected virtual void OnButtonCancelClicked (object sender,
System.EventArgs e)
{
Destroy();
}
public DialogTypeOfPrintEdit ()
{
this.Build ();
// list store
store = new ListStore(typeof (string), typeof (string));
// columns
TreeViewColumn colName = new TreeViewColumn();
TreeViewColumn colActive = new TreeViewColumn();
// titles
colName.Title = "Type of Print";
colActive.Title = "Active";
// column widths
colName.MinWidth = 300;
colName.Resizable = true;
colActive.Alignment.Equals(0.5);
colActive.MinWidth = 30;
colActive.MaxWidth = 40;
// cell renderers
CellRendererText nameRenderer = new CellRendererText();
CellRendererToggle activeRenderer = new
CellRendererToggle();
nameRenderer.Editable = true;
activeRenderer.Activatable = true;
activeRenderer.Toggled += new
ToggledHandler(activeToggle);
activeRenderer.Active = true;
// add renderer to column
colName.PackStart(nameRenderer,true);
colActive.PackStart(activeRenderer,true);
// column number
colName.AddAttribute(nameRenderer,"text",0);
colActive.SetCellDataFunc(activeRenderer, new
TreeCellDataFunc(renderActive));// .AddAttribute(activeRenderer,"active",1);
// add columns to treeview
treeviewTypeOfPrint.AppendColumn(colName);
treeviewTypeOfPrint.AppendColumn(colActive);
// values
store.AppendValues("Cyanotype",0);
store.AppendValues("Ziatype",1);
treeviewTypeOfPrint.Model = store;
treeviewTypeOfPrint.Show();
}
private void activeToggle(object o,ToggledArgs args)
{
TreeIter iter;
//MessageBox.Show("hi");
if (store.GetIterFromString(out iter, args.Path))
{
bool val = (bool) store.GetValue(iter,1);
store.SetValue(iter,1,!val);
}
}
private void renderActive(TreeViewColumn column, CellRenderer
cell,
TreeModel model, TreeIter iter)
{
typeOfPrint p = (typeOfPrint) model.GetValue(iter,1);
if(p.Active.Equals("1")== true)
{
}
//MessageBox.Show(p.Name);
}
}
}
any help would be appreciated.
