makVrv::DtLineEdit Class Reference

A custom QLineEdit for suppressing key-release events. QLineEdit widgets normally consume key-press events while handling text modification, however, key-release events are propagated to their parent for handling. This widget suppresses both key-press and key-release events from being propagated to the parent. Suppressing both event types prevents the root-ancestor from handling either event while this widget is actively being modified. For instance, this prevents key-release events from being handled as keyboard short-cut events while the user is editing text.
