gtk-sharp 0.0.0.0 neutral Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. A widget for displaying both trees and lists. Widget that displays any object that implements the interface. To create a tree or list in GTK#, you need to use the interface, in conjunction with the widget. This widget is designed around a Model/View/Controller design and consists of four major parts: , the tree view widget , the view column. The cell renderers ( and others). , the model interface. The View is composed of the first three, while the last is the Model. One of the prime benefits of the MVC design is that multiple views can be created of a single model. For example, a model mapping the file system could be created for a file manager. Many views could be created to display various parts of the file system, but only one copy need be kept in memory. The purpose of the cell renderers is to provide extensibility to the widget and to allow multiple ways of rendering the same type of data. For example, consider how to render a boolean variable. Should you render it as a string of "True" or "False", "On" or "Off", or should you render it as a checkbox? A simple list: using System; using Gtk; public class TreeViewSample { public static void Main (string [] args) { Application.Init (); TreeStore store = new TreeStore (typeof (string), typeof (string)); for (int i=0; i < 5; i++) { TreeIter iter = store.AppendValues ("Demo " + i, "Data " + i); } Window win = new Window ("TreeView List Demo"); win.DeleteEvent += new DeleteEventHandler (delete_cb); win.SetDefaultSize (400,250); ScrolledWindow sw = new ScrolledWindow (); win.Add (sw); TreeView tv = new TreeView (); tv.Model = store; tv.HeadersVisible = true; tv.AppendColumn ("Demo", new CellRendererText (), "text", 0); tv.AppendColumn ("Data", new CellRendererText (), "text", 1); sw.Add (tv); sw.Show (); win.ShowAll (); Application.Run (); } private static void delete_cb (System.Object o, DeleteEventArgs args) { Application.Quit (); args.RetVal = true; } } A more advanced example: using System; using System.Reflection; using Gtk; public class TreeViewDemo { private static TreeStore store = null; private static Dialog dialog = null; private static Label dialog_label = null; public TreeViewDemo () { Application.Init (); PopulateStore (); Window win = new Window ("TreeView demo"); win.DeleteEvent += new DeleteEventHandler (DeleteCB); win.SetDefaultSize (640,480); ScrolledWindow sw = new ScrolledWindow (); win.Add (sw); TreeView tv = new TreeView (store); tv.HeadersVisible = true; tv.AppendColumn ("Name", new CellRendererText (), "text", 0); tv.AppendColumn ("Type", new CellRendererText (), "text", 1); sw.Add (tv); dialog.Destroy (); dialog = null; win.ShowAll (); Application.Run (); } private static void ProcessType (TreeIter parent, System.Type t) { foreach (MemberInfo mi in t.GetMembers ()) { store.AppendValues (parent, mi.Name, mi.ToString ()); } } private static void ProcessAssembly (TreeIter parent, Assembly asm) { string asm_name = asm.GetName ().Name; foreach (System.Type t in asm.GetTypes ()) { UpdateDialog ("Loading from {0}:\n{1}", asm_name, t.ToString ()); TreeIter iter = store.AppendValues (parent, t.Name, t.ToString ()); ProcessType (iter, t); } } private static void PopulateStore () { if (store != null) return; store = new TreeStore (typeof (string), typeof (string)); foreach (Assembly asm in AppDomain.CurrentDomain.GetAssemblies ()) { UpdateDialog ("Loading {0}", asm.GetName ().Name); TreeIter iter = store.AppendValues (asm.GetName ().Name, "Assembly"); ProcessAssembly (iter, asm); } } public static void Main (string[] args) { new TreeViewDemo (); } private static void DeleteCB (System.Object o, DeleteEventArgs args) { Application.Quit (); } private static void UpdateDialog (string format, params object[] args) { string text = String.Format (format, args); if (dialog == null) { dialog = new Dialog (); dialog.Title = "Loading data from assemblies..."; dialog.AddButton (Stock.Cancel, 1); dialog.Response += new ResponseHandler (ResponseCB); dialog.SetDefaultSize (480, 100); VBox vbox = dialog.VBox; HBox hbox = new HBox (false, 4); vbox.PackStart (hbox, true, true, 0); Gtk.Image icon = new Gtk.Image (Stock.DialogInfo, IconSize.Dialog); hbox.PackStart (icon, false, false, 0); dialog_label = new Label (text); hbox.PackStart (dialog_label, false, false, 0); dialog.ShowAll (); } else { dialog_label.Text = text; while (Application.EventsPending ()) Application.RunIteration (); } } private static void ResponseCB (object obj, ResponseArgs args) { Application.Quit (); System.Environment.Exit (0); } } Gtk.Container Atk.Implementor GLib.IWrapper GLib.IWrapper System.IDisposable Method System.Int32 Removes from . an object of type an object of type Method System.Void Sets a user function for determining where a column may be dropped when dragged. an object of type an object of type an object of type This function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. If is set to be , then reverts to the default behavior of allowing all columns to be dropped everywhere. Method System.Void Moves the alignments of the to the position specified by and . an object of type an object of type an object of type an object of type an object of type If is , then no horizontal scrolling occurs. Likewise, if is no vertical scrolling occurs. At a minimum, one of or need to be non-. determines where the row is placed, and determines where the column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center. If is , then the alignment arguments are ignored, and the tree does the minimum amount of work to scroll the cell onto the screen. This means that the cell will be scrolled to the edge closest to its current position. If the cell is currently visible on the screen, nothing is done. This function only works if the model is set, and is a valid row on the model. If the model changes before the is realized, the centered path will be modified to reflect this change.

If is not , then focus is given to the column specified by it. Additionally, if is specified, and is , then editing should be started in the specified cell. This function is often followed by in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized. Method System.Void Fills with the currently-visible region of the buffer, in tree coordinates. an object of type Convert to widget coordinates with .
