This is not really what I want to do :)
It is not a presentation that I want to update, but the browser itself.
For example, If I have a browser initialized like that:

   browser := GLMTabulator new.
   browser row: #firstRow
   browser transmit to: #firstRow; andShow: [:a |
       a custom: ....

I have no problem to register to annoucments of my model.
What I would like to do, when the event I register for occure,is to add or delete some 'row' of my browser. A simple way would be to 'clean' the browser (by removing all its content, all its 'rows') and then re-set it some row and columns according the event I intercept.

I don't know how to 'clean' the browser (?)

You basically want to update a presentation which, given that you talk about rows, seems to be a table.

In this case, you have two options:

1. register to an announcement from your model:

a table
       updateOn: YourAnnouncement from: [ :entity | "computation of the announcer" ];

2. in case the model does not offer announcements, you can just manually trigger an update:

a table
       act: [ :table | table update ] entitled: 'Refresh'

When an update is sent (either directly or indirectly via announcements), the complete table is refreshed.

Does that help?

I have a browser, which is a GLMTabulator.
I would like to dynamically change its number of rows.
Is there a way to do that?

My idea was:
Every time I want to update my browser, I delete all existing rows and rebuild the ones i want. Is it possible?
