<summary>Report messages of minor importance to the user.</summary>
<remarks>
<para>The Statusbar widget displays textual messages to the user. Statusbars are typically placed at the bottom of application <see cref="T:Gtk.Window" />s.</para>
<para>A Statusbar may provide a regular commentary of the application's status (as is usually the case in a web browser, for example), or may be used to simply output a message when the status changes, (when an upload is complete in an FTP client, for example).</para>
<para>As a finishing touch to the StatusBar, it can have a "resize grip" added in the lower right corner. This is a triangular area that can be clicked on to resize the window containing the statusbar.</para>
<para>Status bars in Gtk maintain a stack of messages. The message at the top of the each bar's stack is the one that will currently be displayed.</para>
<para>Any messages added to a statusbar's stack must specify a <paramref name="context_id" /> that is used to uniquely identify the source of a message. This <paramref name="context_id" /> can be generated with <see cref="M:Gtk.Statusbar.GetContextId" />, given a message. Note that messages are stored in a stack, and when choosing which message to display, the stack structure is adhered to, regardless of the context identifier of a message.</para>
<para>Messages are added to the bar's stack with <see cref="M:Gtk.Statusbar.Push" />, and the message at the top of the stack can be removed using <see cref="M:Gtk.Statusbar.Pop" />. A message can be removed from anywhere in the stack if it's <paramref name="message_id" /> was recorded at the time it was added. This is done using <see cref="M:Gtk.Statusbar.Remove" />.</para>
<example>
<code lang="C#">
using System;
using Gtk;
class StatusbarSample
{
Statusbar sb;
const int id = 1;
int count;
static void Main ()
{
new StatusbarSample ();
}
StatusbarSample ()
{
Application.Init ();
count = 0;
Window win = new Window ("StatusbarSample");
win.DeleteEvent += new DeleteEventHandler (OnWinDelete);
win.SetDefaultSize (150, 100);
VBox vbox = new VBox (false, 1);
win.Add (vbox);
Button btn = new Button ("Add to counter");
btn.Clicked += new EventHandler (OnButtonClicked);
vbox.Add (btn);
sb = new Statusbar ();
sb.Push (id, "Welcome!");
sb.HasResizeGrip = false;
vbox.Add (sb);
win.ShowAll ();
Application.Run ();
}
void OnButtonClicked (object obj, EventArgs args)
{
count ++;
string message = String.Format ("Pushed {0} times", count);
sb.Pop (id);
sb.Push (id, message);
}
