There aren't really any "ROI Drawn" events in the viewer. The closest you can get is ImageViewer.EventBroker.MouseCaptureChanged, but that doesn't tell you when a ROI is drawn. What you would do is look at the ROIs in the current image when capture=true, then when capture=false, check that the currently selected graphic wasn't there when capture was first obtained.

If you just want something to pop up whenever somebody selects a ROI, you can use the GraphicSelectionChanged event on the broker. Each time the user clicks on a ROI, the event will fire and you can pop something up.

As for how to pop something up, that's up to you, but the easiest way is to create a new ApplicationComponent and use ApplicationComponent.LaunchAsShelf with DockFloat | ShowNearMouse as the "display hint". To do anything really custom, you'd have to create a custom view, like IMagnificationView, which is used to show the "magnifying glass" in a form.

If you go the shelf route, you should probably close it whenever there's no graphic selected anymore (or probably whenever graphic selection changes so you can get it to show up close to the mouse).

Can I ask why you want to pop something up, rather than just add a new statistic to the existing ROI callouts? You can do that via a plugin.
