    <summary>A button that can be toggled on and off.</summary>
    <remarks>
      <para>A <see cref="T:Gtk.ToggleButton" /> is a <see cref="T:Gtk.Button" /> which will remain 'pressed-in' when clicked.
	  Clicking again will cause the toggle button to return to its normal state.  This is useful if you need to maintain the state of a button.</para>

						If the user has selected a range of elements (such as some text or spreadsheet cells) that are affected by a <see cref="T:Gtk.ToggleButton"/>,
						and the current values in that range are inconsistent, you may want to display the toggle in an "in between" state.
						This function turns on "in between" display. Normally you would turn off the inconsistent state again if the user toggles the <see cref="T:Gtk.ToggleButton"/>.
						This has to be done manually, <see cref="P:Gtk.ToggleButton.Inconsistent" /> only affects visual appearance, it does not affect the semantics of the <see cref="T:Gtk.Button"/>.
