[platform-swt-dev] SWT Browser How-to show new composite

[Gerald <gerald.radix@xxxxxxxxx>]

When an error is catch (Error 404) I would like show a new composite (parentController.showProbemeOpenflyers) but my application block to the current browser.

parentController.showProblemeOpenflyers make a stackLayout.topControl to set a Composite ProblemeOpenflyers and make a setLayout()

How do make  this ?
