How to disable context menu of a toolbar in QMainApplication

[mtrpoland]

Something like this?

MWin inherits QMainWindow

bool MWin::eventFilter(QObject* object, QEvent* event) {
	if(event->type() == QEvent::ContextMenu) {
		QContextMenuEvent* mevent = static_cast<QContextMenuEvent *>(event);
		if(mevent->reason() == QContextMenuEvent::Mouse) {
			qDebug("I have blocked the context menu.");
			return true;
		} else return QObject::eventFilter(object, event);
	}
	else return QObject::eventFilter(object, event);
}

bool MWin::eventFilter(QObject* object, QEvent* event) {
	if(event->type() == QEvent::ContextMenu) {
		QContextMenuEvent* mevent = static_cast<QContextMenuEvent *>(event);
		if(mevent->reason() == QContextMenuEvent::Mouse) {
			qDebug("I have blocked the context menu.");
			return true;
		} else return QObject::eventFilter(object, event);
	}
	else return QObject::eventFilter(object, event);
}

To copy to clipboard, switch view to plain text mode 

and installation:

...
fileToolBar->installEventFilter(this);
...
modeToolBar->installEventFilter(this);
...
actionToolBar->installEventFilter(this);
...

...
fileToolBar->installEventFilter(this);
...
modeToolBar->installEventFilter(this);
...
actionToolBar->installEventFilter(this);
...

More like this. You must test for the objects you're installing the filter for.

bool MWin::eventFilter(QObject* object, QEvent* event) {
          if(event->type() == QEvent::ContextMenu && 
           ( object == fileToolbar || object == modeToolBar ... ) ) {
              QContextMenuEvent* mevent = static_cast<QContextMenuEvent *>(event);
              if(mevent->reason() == QContextMenuEvent::Mouse) {
                  qDebug("I have blocked the context menu.");
                  return true;
              } else 
                 return false;
          }
          else 
                return QObject::eventFilter(object, event);
      }

bool MWin::eventFilter(QObject* object, QEvent* event) {
          if(event->type() == QEvent::ContextMenu && 
           ( object == fileToolbar || object == modeToolBar ... ) ) {
              QContextMenuEvent* mevent = static_cast<QContextMenuEvent *>(event);
              if(mevent->reason() == QContextMenuEvent::Mouse) {
                  qDebug("I have blocked the context menu.");
                  return true;
              } else 
                 return false;
          }
          else 
                return QObject::eventFilter(object, event);
      }
