getDefaultPerspective

public String getDefaultPerspective()

Returns the id of the default perspective for the workbench. This identifies one perspective extension within the workbench's perspective registry.

On startup of the platform UI the default perspective is determined using a multistep process.

1. Initially the Resource Perspective is default.
2. If a single perspective extension within the registry has a default attribute it will become the default perspective. If two or more extensions have the default attribute the registry will ignore all of them and select the Resource Perspective.
3. If the user has set the default perspective within the Perspective dialog their preference will be selected over all others.

Returns:

the default perspective id; will never be null
