<div><p>The functions implemented by a plug-in logically are grouped into <span class="uicontrol">Component Object Model (COM) interfaces</span>.</p>
|
||
|
|
<p>An interface is a set of logically related methods on a class that iSeries™ Navigator can call to perform a specific function.
|
||
|
|
A plug-in may implement one or more COM interfaces, depending on the type of function that the developer intends to provide. For example, when a user right-clicks an object in the tree hierarchy, iSeries Navigator constructs a context menu for the object and displays the menu on the screen. The Navigator obtains the menu items by calling each
|
||
|
|
plug-in that has registered its desire to supply context menu items for the selected object type. The plug-ins pass their menu items to the Navigator when it calls their implementation of the <span class="uicontrol">QueryContextMenu</span> method
|
||
|
|
on the <span class="uicontrol">IContextMenu interface</span>.</p>

<div class="section"><h4 class="sectiontitle">IA4 interfaces</h4><p>In addition to Microsoft's COM interfaces, IBM<sup>®</sup> supplies the IA4HierarchyFolder and
|
||
|
|
IA4PropSheetNotify interfaces.</p>
|
||
|
|
<p>IA4PropSheetNotify, notifies third-party property pages when the main dialog closes. It also defines methods that communicate information to the plug-in. For example,
|
||
|
|
the method may communicate whether the iSeries user whose properties are being displayed already exists or is being defined,
|
||
|
|
and whether changes should be saved or discarded.</p>
|
||
|
|
<p>IA4HierarchyFolder allows a plug-in to add new folders to the iSeries Navigator
|
||
|
|
hierarchy. The purpose of this interface is to supply the data used to populate the contents of a new folder that your plug-in added to the Navigator hierarchy. It also defines methods for specifying list
|
||
|
|
view columns and their headings, and for defining a custom toolbar that is associated with a folder.</p>

|
||
|
|
The IA4HierarchyFolder interface describes a set of functions that the independent software vendor will implement. IA4HierarchyFolder is a component object model (COM) interface that IBM defined for the purpose of allowing third parties to add new folders and objects to the iSeries Navigator hierarchy.</li>

|
An item identifier, or data entity, identifies all folders and
|
||
|
|
objects in the Windows namespace. Item identifiers are like filenames
|
||
|
|
in a hierarchical file system. The Windows namespace is, in fact, a hierarchical
|
||
|
|
namespace with its root at the Desktop.</li>

|
|
<li class="ulchildlink"><strong><a href="rzakxdescia4propsheet.htm">Description of IA4PropSheetNotify interface</a></strong><br />
|
||
|
|
Like the IA4HierarchyFolder interface, the IA4PropSheetNotify interface describes a set of functions that the independent software vendor will implement. IA4PropSheetNotify is a COM interface IBM defined to allow third parties to add new property pages to any property sheet that the iSeries Navigator defines for an iSeries server user.</li>

<li class="ulchildlink"><strong><a href="rzakxia4propsheetifspec.htm">IA4PropSheetNotify interface specifications listing</a></strong><br />
|

The IA4PropSheetNotify interface supplies notifications to the implementation of IShellPropSheetExt that are needed when adding additional property pages to one of the Users and Groups property sheets.</li>
