Thank you Prashanth. Your approach could be useful in *many* situations.
Thank you! -Ed On Feb 1, 2016, at 10:28 AM, Prashanth Udupa <prashanth.ud...@gmail.com<mailto:prashanth.ud...@gmail.com>> wrote: Create a Event2Signal class as follows. #include <QMap> #include <QList> #include <QEvent> #include <QObject> class Event2Signal : public QObject { Q_OBJECT public: Event2Signal(QObject *parent=0) : QObject(parent) { } ~Event2Signal() { } void filterEvent(QObject *o, QEvent::Type type) { if(!o) return; if( m_objectEventsMap.contains(o) ) { QList<QEvent::Type> &events = m_objectEventsMap[o]; if(events.contains(type)) return; events.append(type); } else { m_objectEventsMap[o].append(type); o->installEventFilter(this); } } signals: void filteredEvent(QObject *o, QEvent *e, bool *filtered); protected: bool eventFilter(QObject *obj, QEvent *e) { bool filtered = false; emit filteredEvent(obj, e, &filtered); return filtered; } private: QMap<QObject *, QList<QEvent::Type> > m_objectEventsMap; }; Now, lets say you want to take some action when user mouse-presses on a lineEdit. You can do this Event2Signal *e2s = new Event2Signal(lineEdit); e2s->filterEvent(lineEdit, QEvent::MouseButtonPress); connect(e2s, &Event2Signal::filteredEvent, [=]() { // Activate your form and do other things here.. }); You can reuse this method for handling other kinds of events in signal-slot style. Hope this helps. / Prashanth On Mon, 1 Feb 2016 at 21:41 Edward Sutton <edward.sut...@subsite.com<mailto:edward.sut...@subsite.com>> wrote: I want to display a form with a numeric touch key pad plus a decimal point when user clicks on a QLIneEdit field. I did not see any signal such as editingStarted. What are approaches to implementing a custom data entry?
