gtk-sharp2.12.0.0Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details.A text entry field with a dropdown list
The widget consists of a single-line text entry field and a
drop-down list. The drop-down list is displayed when the user clicks
on a small arrow button to the right of the entry field.
The drop-down list is a widget and can be accessed using the
list member of the . List elements can contain arbitrary
widgets, but if an element is not a plain label, then you must use
the function. This sets the string which
will be placed in the text entry field when the item is selected.
By default, the user can step through the items in the list using the
arrow (cursor) keys, though this behaviour can be turned off with
= .
Creating a widget with simple text items:
using System;
using Gtk;
class ComboSample
{
Combo combo;
static void Main ()
{
new ComboSample ();
}
ComboSample ()
{
Application.Init ();
Window win = new Window ("ComboSample");
win.DeleteEvent += new DeleteEventHandler (OnWinDelete);
string[] list = new string[] {"one", "two", "three"};
combo = new Combo ();
combo.PopdownStrings = list;
combo.DisableActivate ();
combo.Entry.Activated += new EventHandler (OnEntryActivated);
win.Add (combo);
win.ShowAll ();
Application.Run ();
}
void OnEntryActivated (object o, EventArgs args)
{
Console.WriteLine (combo.Entry.Text);
}
void OnWinDelete (object obj, DeleteEventArgs args)
{
Application.Quit ();
}
}
