 <p>Now that we have the work area coordinate for the right-hand edge of the visible toolbar, we can use <swi>Wimp_ResizeIcon</swi> to set the right-hand coordinate of the icon to be 4 OS&nbsp;Units in to the left from this. The Wimp won't refresh the display for us, however, so we also need to call <swi>Wimp_ForceRedraw</swi> for the whole area of the icon <em>and</em> the space between it and the edge of the toolbar.</p>
 
-<p>Since this is a writeable icon, there&rsquo;s one final gotcha that we must be aware of. If the caret was in the icon, the Wimp won&rsquo;t move it to reflect any alteration to the position of the text. Instead we use <swi>Wimp_GetCaretPosition</swi> to find out where the caret is currently located and, if it is in our icon, call <swi>Wimp_SetCaretPosition</swi> to replace it in exactly the same place within the text.</p>

 <p>The toolbar window itself has also been updated, removing the pair of action buttons and the writeable field. In their place are four &lsquo;heading&rsquo; icons, which should line up with the columns of coloured squares in the main window. The buttons are now passive &ndash; neither visibly pressing nor generating <name>Mouse_Click</name> events &ndash; although as before this is merely cosmetic.</p>
