ArcObjects Library Reference (CatalogUI)

IGxApplication Interface

Provides access to members that control the Gx Application object.

Product Availability

Available with ArcGIS Desktop.

Description

The IGxApplication interface is unique to ArcCatalog and is used to control certain aspects of its behavior. For example, through the IGxApplication interface, you can delete or expand the current selection (through DeleteSelection and ExpandSelection) or force a refresh of a certain part of the Catalog tree (through Refresh). You can also get hold of the currently selected object(s) through the Selection and SelectedObject properties.

The Catalog property returns the GxCatalog object, which represents the root of the Catalog data tree. From there, you can use IGxObjectContainer::Children to enumerate through the Catalog’s descendants.

The TreeView property gives you access to ArcCatalog’s tree view. From this GxTreeView, you can ensure that a certain descendant is visible or initiate a renaming operation.

The View property gives you access to the active GxView, whatever it happens to be. It might be one of the built-in views—for example, GxContentsView, GxPreview, or GxMetadataView—or it might be a developer- added one. From here, you can manipulate the active view in whatever fashion is native to it.
