<summary>Encapsulates an adjustable bounded value.</summary>
|
|
<remarks>
|
|
<para>The Adjustment object represents a value with an associated <see cref="P:Gtk.Adjustment.Lower" /> and <see cref="P:Gtk.Adjustment.Upper" /> bound, together with a <see cref="P:Gtk.Adjustment.StepIncrement" />, <see cref="P:Gtk.Adjustment.PageIncrement" />, and a <see cref="P:Gtk.Adjustment.PageSize" />.</para>
|
|
<para>The Adjustment object does not update the value itself. Instead it is left up to the owner of the Adjustment to control the value. The owner of the Adjustment typically calls the <see cref="M:Gtk.Adjustment.ValueChanged" /> and <see cref="M:Gtk.Adjustment.Changed" /> methods after changing the value or its bounds, respectively. This results in the emission of the <see cref="F:Gtk.Adjustment.ValueChanged" /> or <see cref="F:Gtk.Adjustment.Changed" /> events respectively.</para>
|
|
<para>An Adjustment is used within several widgets, including <see cref="T:Gtk.SpinButton" />, <see cref="T:Gtk.Viewport" />, and <see cref="T:Gtk.Range" /> (which is a base class for <see cref="T:Gtk.HScrollbar" />, <see cref="T:Gtk.VScrollbar" />, <see cref="T:Gtk.HScale" />, and <see cref="T:Gtk.VScale" />).</para>

This method should be used to set the currently visible range to (<paramref name="lower" />, <paramref name="upper" />).?If necessary, the current <see cref="P:Gtk.Adjustment.Value" /> is changed to ensure that it is visible within the new scope.

The <see cref="F:Gtk.Adjustment.ValueChanged" /> event will be fired if the <see cref="P:Gtk.Adjustment.Value" /> changes as a result of this method. <see cref="M:Gtk.Adjustment.Change" /> must be called manually if the <see cref="F:Gtk.Adjustment.Changed" /> event should be fired.
