i wanted to implement a login function in my rap app that works this way:
- a login dialog pops up and the user has to login using his username and
password
- after the login, the perspective that is opened, depends on the role of
the user (e.g. i differ between the roles 'administration' and
'management')
- if the user logs out he'll return to the login view
until now, i realised it using different perspective for the user roles.
at the beginning the 'login perspective' is shown with a standalone view
containing the login widgets. the user logs in and the perspective id for
his role is extracted from a database. the code looks like this:
IPerspectiveDescriptor pers =
PlatformUI.getWorkbench().getPerspectiveRegistry().findPersp ectiveWithId(DBConn.getResultString(1));
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().setPerspective(pers);
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().resetPerspective();
getResultString returns the id of the appropiate perspective for the user
from a database. when the user logs out, the perspective is changed to the
login perspective. the code for the logout event looks like this:
IPerspectiveDescriptor pers =
PlatformUI.getWorkbench().getPerspectiveRegistry().findPersp ectiveWithId(PerspectiveLogin.ID);
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().setPerspective(pers);
the problem is, if the users logs out, the perspective just changes but
isn't 'closed'. is there a possibility to close (delete) the perspective
completely so that it will be re-created if he logs in again without
closing the app?
however i'm not really satisfied with this solution because it seems too
cobbled :P.
maybe someone has an advice on how to implement the login more elegant, or
maybe there is a common scheme to do this.
i'd appreciate your help.

Hi,
sorry for not responding to your question for so long, but somehow I
overlooked it. To close a perspective I would try the
IWorkbenchPage#closePerspective(IPerspectiveDescriptor,boole an,boolean)
method.
Unfortunately there is no common solution for user/role based management of
UIs in RAP or RCP. There is a discussion going on at
https://bugs.eclipse.org/bugs/show_bug.cgi?id=201052 to find a general
solution in RCP which will be hopefully adaptable for RAP too.
Ciao

hi!
yes, that's the effect i wanted to achive. the perspectives and view are
re-created after a new login.
thanks a million.
for everyone who needs a "pseudo role login model" here are a few snippets
:)
login part:
IPerspectiveDescriptor pers =
PlatformUI.getWorkbench().getPerspectiveRegistry().findPersp ectiveWithId( "id
of the role perspective");
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().setPerspective(pers);
logout part:
IPerspectiveDescriptor pers =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().getPerspective();
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().closePerspective(pers,
false, false);
pers =
PlatformUI.getWorkbench().getPerspectiveRegistry().findPersp ectiveWithId( "id
of the login perspective");
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().setPerspective(pers);
regards
