Connect to...without slots...

[Peppy]

I have code:

int main(int argv, char * argc[])
{
  QApplication app(argv,argc);
 
   QWidget* window = new QWidget;
 
  window->setGeometry(QRect(200,200,300,300));
  window->setWindowTitle("QFileDialog example");
  window->setMaximumSize(300,300);
  window->setMinimumSize(300,300);
 
   QPushButton *newFile = new QPushButton("New File Dialog");
   newFile->setGeometry(QRect(50,25,250,35));
 
 
   QPushButton *saveFile = new QPushButton("Save File Dialog");
   saveFile->setGeometry(QRect(50,75,250,35));
 
 
       QGridLayout *layout = new QGridLayout;
       layout->addWidget(newFile,0,0,1,1,Qt::AlignHCenter);
       layout->addWidget(saveFile,1,0,1,1,Qt::AlignHCenter);
 
       window->connect(...); // ?
 
 
  window->setLayout(layout);
  window->show();

int main(int argv, char * argc[])
{
  QApplication app(argv,argc);

   QWidget* window = new QWidget;

  window->setGeometry(QRect(200,200,300,300));
  window->setWindowTitle("QFileDialog example");
  window->setMaximumSize(300,300);
  window->setMinimumSize(300,300);

   QPushButton *newFile = new QPushButton("New File Dialog");
   newFile->setGeometry(QRect(50,25,250,35));


   QPushButton *saveFile = new QPushButton("Save File Dialog");
   saveFile->setGeometry(QRect(50,75,250,35));


       QGridLayout *layout = new QGridLayout;
       layout->addWidget(newFile,0,0,1,1,Qt::AlignHCenter);
       layout->addWidget(saveFile,1,0,1,1,Qt::AlignHCenter);

       window->connect(...); // ?


  window->setLayout(layout);
  window->show();

To copy to clipboard, switch view to plain text mode 

I need to connect button with function ( I don't have class )
something like:

window->connect(newFile,SIGNAL(cliecked()),newFile,SLOT( myImaginedFunc()));

window->connect(newFile,SIGNAL(cliecked()),newFile,SLOT( myImaginedFunc()));

To copy to clipboard, switch view to plain text mode 

doesn't work because it calls:

QPushButton::myImaginedFunc()

QPushButton::myImaginedFunc()

To copy to clipboard, switch view to plain text mode 

which doesn't exist.

You could try to write a new function which would be located underneeth (or above) your main() function.

your connect statement would be something like:

window->connect(newFile,SIGNAL(clicked()),this,SLOT( myImaginedFunc()));

window->connect(newFile,SIGNAL(clicked()),this,SLOT( myImaginedFunc()));

To copy to clipboard, switch view to plain text mode 

I can imagine that you would have to define 'myImaginedFunc()' as a slot somewhere. I don't know if this can be done in your .cpp file. You might want to create a .h file to do this in.

If this doesn't work, it might be easier to just create a class from which you create your window. The slot can be defined in this class.

Good luck.

I think you can create an auxiliary class which will have your function and yhis function will be declared as a slot. In this case your connect statement will be valid.

But in general, I think this is not a normal situation and i think you need to review your application's design.
