this is the source and the error is occuring on line "5":
int main( int argc, char** argv )
{
QApplication app( argc, argv );
testWindow *tw = new testWindow();
tw->setCaption("test");
app.setMainWidget( tw );
tw->show();
app.connect(&app, SIGNAL(lastWindowClosed()),&app, SLOT(quit() ));
return app.exec();
}

There is not enough code! Show header and implementation of your testWindow class.

testWindow - show include header of this class please

this is my header file:
#include <qmainwindow.h>
class QWorkspace;
class QTextEdit;
class testWindow : public QMainWindow
{
Q_OBJECT
public:
testWindow( QWidget* parent = 0, const char* name = 0, WFlags f = WType_TopLevel );
testWindow();
~testWindow();
protected:
QWorkspace *mdi;
protected slots:
void something();
private slots:
private:
};
and this is my implementation file:
#include "testwindow.h"
// here are othe qt header files.
testWindow::testWindow( QWidget* parent, const char* name, WFlags f )
: QMainWindow( parent, name, f )
{
//here comes my code
}

testWindow( QWidget* parent = 0, const char* name = 0, WFlags f = WType_TopLevel );
testWindow();
Both of these constructors can be invoked without parameters and compiler doesn't know which one to choose. Do you need that second constructor?

:D
you have decalre 2 empty constructor!
p.s. too slow:o
p.p.s. useless thread:o

oeps i found it :)
i got this warning:
multiple default constructors specified
and i have removed these lines:
testingWindow();
~testingWindow();
it works now fine..

this is my header file:
#include <qmainwindow.h>
class QWorkspace;
class QTextEdit;
class testWindow : public QMainWindow
{
Q_OBJECT
public:
testWindow( QWidget* parent = 0, const char* name = 0, WFlags f = WType_TopLevel );
testWindow();
~testWindow();
//skip
};
Let's see...
testWindow *tw = new testWindow();
could be interpreted as both
testWindow *tw = new testWindow::testWindow();
and
testWindow *tw = new testWindow::testWindow(0, 0, WType_TopLevel);
That's why you get ambiguous call to overloaded function error. :)

testingWindow();
~testingWindow();...Don't remove the destructor, the poor thing never caused you any harm :)
