Member Function Documentation

void VisHtmlRootBrowser::browse

(

IgRepresentable *

object

)

[virtual]

Begin browsing the object.

The implementation must represent object in all its models. object (its representation, that is) may then be made the current selection of this and all other browsers in the same IgSession as this browser. This last step should be implemented by broadcasting a IgSelectMessage on the session IgSelectionService; the browser itself can simply respond to the message as it is delivered to it.

Note:

The browser has to create a model and a rep of the object; even simple dummy ones will do. These can be discarded once the other browsers have been notified of the selection change.

See also:

See the class documentation for a more complete description.

Parameters:

object

The object to visualise. Even though the object is not const, the browser should not assume it can change it. All non-editor browsers should treat the object purely as const. Editors should treat the object as const as long as possible, preferably until the user explicitly requests the object to be changed. Thus, editors should make changes only to the representation until it is clear that the user is committed to making the changes to the object, too.

Implements IgBrowser.
