[Lazarus] I can't exit this component

[Marc Weustink]

The onenter is indeed fired when the control gets focus. However if you show a dialog in that event, the control loses focus and gets it again when the dialog is closed, resulting in a loop.
In general it is  bad coding to have much logic in onenter/onleave events 

I once was confronted with an app which checked if you didn't leave an empty mandatory edit. If so, the app set the focus back to the control you left. But if you navigated to the next empty mandatory edit it ran into an endless loop focussing both edits
