Add Static area to QGraphicsView

[stampede]

This is the MainWindow class header.

Well, I can agree that this could be a part of MainWindow class header

There should be nothing wrong in your code, my quick test looks very similar and works:

// test.h
#include <QtGui>
 
class MainW : public QMainWindow{
	Q_OBJECT
 
	QGraphicsView * view;
 
public:
	explicit MainW( QWidget * parent = NULL );
public slots:
	void warning( int value ){
		this->setWindowTitle(QString::number(value));
	}
};
 
// test.cpp
#include "test.h"
 
MainW::MainW( QWidget * parent ) : QMainWindow(parent){
	view = new QGraphicsView(this);
	QGraphicsScene * scene = new QGraphicsScene(this);
	scene->setSceneRect(0,0,1000,1000);
	view->setScene(scene);
	this->setCentralWidget(view);
	connect( view->verticalScrollBar(), SIGNAL(valueChanged(int)), this, SLOT(warning(int)) );
}
 
int main(int argc, char *argv[]){	
    QApplication a(argc, argv);
    MainW m;
    m.show();
    return a.exec();
}

// test.h
#include <QtGui>

class MainW : public QMainWindow{
	Q_OBJECT
	
	QGraphicsView * view;
	
public:
	explicit MainW( QWidget * parent = NULL );
public slots:
	void warning( int value ){
		this->setWindowTitle(QString::number(value));
	}
};

// test.cpp
#include "test.h"

MainW::MainW( QWidget * parent ) : QMainWindow(parent){
	view = new QGraphicsView(this);
	QGraphicsScene * scene = new QGraphicsScene(this);
	scene->setSceneRect(0,0,1000,1000);
	view->setScene(scene);
	this->setCentralWidget(view);
	connect( view->verticalScrollBar(), SIGNAL(valueChanged(int)), this, SLOT(warning(int)) );
}
 
int main(int argc, char *argv[]){	
    QApplication a(argc, argv);
    MainW m;
    m.show();
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

Try to make a clean build ( make clean, qmake, make ). If this doesn't help, post full code (if you can).

stampede,

I just made a new project and copied your example and i get the same error.

if i edit out the connect line it builds and runs as expected?

am using QT 4.7 on a mac.

any further suggestions?

Thanks,

That's really weird, I'm sorry but I can't help you more, because my experience with mac == 0
I see that you have Unix and Windows in your profile info, does all of this works on those systems, can you check that ?

[dubstar_04]

i am just uninstalling all the Qt stuff off my mac as i have loads of different versions. I will try and build it again once i have reinstalled everything.

I will try the linux and windows machines if that doesnt work.

Thanks for all your help.

update:
Reinstalled qt on mac. same error.
it wouldnt build on linux either. same issue.
