Unsolved Show with qdebug keyevent
-
Hi i want to show my filter in my main function but i couldn't.
```
Código filter.h:
#ifndef FILTRODEEVENTOSPERSONALIZADO_H
#define FILTRODEEVENTOSPERSONALIZADO_H#include <QObject> class FiltroDeEventosPersonalizado : public QObject { Q_OBJECT protected: bool eventFilter(QObject *obj, QEvent *event) override; }; #endif // FILTRODEEVENTOSPERSONALIZADO_H
Código filter.cpp: ``` #include "filtrodeeventospersonalizado.h" #include <QEvent> #include <QDebug> #include <QKeyEvent> bool FiltroDeEventosPersonalizado::eventFilter( QObject *obj, QEvent *event) { if (event->type() == QEvent::KeyPress) { QKeyEvent* keyEvent = static_cast<QKeyEvent*>(event); if( keyEvent->key() == Qt::Key_A ) qDebug() << "Tecla 'A' presionada"; return true; } return QObject::eventFilter(obj, event); }
Main:
```
#include <QCoreApplication>
#include <filtrodeeventospersonalizado.h>
#include <QDebug>
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
FiltroDeEventosPersonalizado *filtro = new FiltroDeEventosPersonalizado;
a.installEventFilter(filtro);
return a.exec();
}Hi i only want to show since qdebug my key pressed A. thx

if thats all the code you are using, then maybe it is caused by the fact that there is no widget/window which would receive the key event. -
@raven-worx but i can't show the event? with qdebug?

@RIVOPICO
as i said: there is no key event when there is no window to receive it.
Create one and it should work as expected.
