new helpFrame()

var h = new helpFrame(left,top,width,height,<refDiv>)
creates a helpFrame with the specified size and position, optionally specified as percentages, optionally relative to a previously defined DHTML element. Like all MapClient objects, its internal layout properties can be reached by its "div" property, like h.div.style. A helpFrame has several subelements, e.g. titleBar, titleText and textArea. These are regular DOM elements, so their appearance can be changed, e.g. "h.textArea.style.backgroundColor". A helpFrame responds to moving and minimizing (by just clicking the titlebar), but not to resizing. A helpFrame with just the size of the titlebar can be used to navigate through an application without accompanying text. In that case "addPage()" can be called with null as first parameter.

Once a helpFrame is created, it has to be filled in by the "addPage()" method. Each page can contain both text, Javascript DOM variables or MapClient objects like windows and menus. When selecting a page, only objects belonging to that page will be shown.
