        <short>
          Enumerated type with the display order used for buttons on TButtonPanel.
        </short>
        <descr>
          <p>
            <var>TButtonOrder</var> is an enumeration with values which indicate the display order used for buttons on <var>TCustomButtonPanel</var> and <var>TButtonPanel</var>.
          </p>
          <p>
            The value <var>boDefault</var> has a special meaning, and causes the button order to be set to the sequence normally used for the platform or operating system.
          </p>
          <p>
            For example:
          </p>
          <dl>
            <dt>UNIX-like environments</dt>
            <dd>Uses Ok, Cancel, Close, and Help button order.</dd>
            <dt>All other platforms</dt>
            <dd>Uses Cancel, Ok, Close, and Help button order.</dd>
          </dl>
          <p>
            TButtonOrder is the type used to implement the <var>TCustomButtonPanel.ButtonOrder</var> property.

        <descr>
          <p>
            <var>ButtonOrder</var> is a <var>TButtonOrder</var> property which indicates the order of the buttons displayed on the panel. The default value for the property is <var>boDefault</var>, and causes the button order to be set to the sequence normally used for the platform or operating system.
          </p>
          <p>
            For example:
          </p>

            Use <var>boCloseCancelOK</var> or <var>boCloseOKCancel</var> to set the button order where <b>Help</b> is always the last button displayed.
          </p>
          <p>
            Changing the value in ButtonOrder causes the button panel to be re-drawn.

            <var>ShowButtons</var> is a <var>TPanelButtons</var> property which contains the set of buttons displayed on the panel. The default value for the property is defined in the <var>DefShowButtons</var> constant.

          <p>
            Use ShowGlyphs to indicate which buttons have an image displayed on the button surface.
          </p>
          <p>
            For example:
          </p>

            A default glyph image is provided for each TPanelBitBtn instance on the panel using the internal button name, like "OKButton" or "CancelButton". The default glyph image is loaded from LCL glyph resources when the button is created. Use OkButton, CancelButton, CloseButton, and HelpButton to provide custom values used in the panel buttons.
          </p>
          <p>
            Use ShowButtons to control which buttons are displayed on the panel. For example:

<code>

// use Ok and Cancel buttons only
AButtonPanel.ShowButtons := [pbOk, pbCancel];
AButtonPanel.ShowGlyphs := [pbOk, pbCancel];
