Hi Wim, Tried it. Pretty nice. :)
Yet, just out of curiosity: is there a particular reason why you didn't use a custom org.eclipse.jface.dialogs.Dialog internally which takes care of all the rendering already? That would make the framework taking care of stuff like positioning, themabilty and so on. I have noticed that there's alreday some similar widget available from Nebula, i.e.. the Notifier: https://wiki.eclipse.org/Nebula_Notifier Maybe it might be a good idea to enhance that one and make it configurable in regard to coloring and the position where it opens instead of creating another new wiget? As a user, I'd prefer to have a smaller set of highly configurable widgets instead of a multitude of widgets with some of them doing similar stuff. What do you think? Best, MP Am Mi., 7.
