RE: EventFilters

Quoted

From Qt docs:
void QObject::installEventFilter ( QObject * filterObj )
Installs an event filter filterObj on this object. For example:
monitoredObj->installEventFilter(filterObj);

So in your case that obj parameter will point to the "load" button.

bool MyWidget::eventFilter(QObject* obj, QEvent* e) {
     if (obj == w->load ) {
		cout << "myWidget\n";
		if (( e->type() == QEvent::MouseButtonDblClick) || ( e->type() ==    
                           QEvent::MouseMove)) {
		  cout << "mo";
		  return  true;
		} 
		else {
			cout << "false\n";
			return false;
		}
	}

The fisrt if don't compile because w->load is a QPushButton and not a
QObject.....

RE: mouseMoveEvent & QFileDialog

1. #include <qpushbutton.h>

2. You lack basic C++ knowledge, so: http://www.mindview.net/Books/TICPP/ThinkingInCPP2e.html

3. I give you a little "warning" -- this forum is not a virtual compiler, it doesn't release you from necessity of thinking and reading the docs. Your issues are plain algorithmic and/or "cplusplusish", and not really related to Qt. You are not trying to do anything on your own, but when you encounter a problem, you come here and ask us to solve it. It cannot continue this way. This thread has more than 20 posts now and it looks like you are not even a step closer to a solution. So if you want us to give you hints (hints, not complete solutions), please try to think on your own a little or I will close this thread.

I advise you to look at examples that come with Qt and use your head a little more. Thank you in advance for cooperation.
