I need help for signals

[avis_phoenix]

Well i was created a QT Dialog and i need create a signal for this dialog, in such a way that when it does click in a button I warned that I did click to him (this outside of dialog).
Then i need a tutorial for create a signals to use in connect

You could use "signal chaining" (connecting a signal to another signal) for achieving this. See the example below:

class MyDialog : public QDialog
{
	// don't forget this macro whenever you declare
	// custom signals and/or slots
	Q_OBJECT
 
public:
	MyDialog(QWidget* parent = 0);
 
	// declare a custom signal
signals:
	void someButtonClicked();
};
 
MyDialog::MyDialog(QWidget* parent) : QDialog(parent)
{
	// form a connection between the button and the dialog
	connect(someButtonInTheDialog, SIGNAL(clicked()), this, SIGNAL(someButtonClicked()));
}

class MyDialog : public QDialog
{
	// don't forget this macro whenever you declare
	// custom signals and/or slots
	Q_OBJECT

public:
	MyDialog(QWidget* parent = 0);
	
	// declare a custom signal
signals:
	void someButtonClicked();
};

MyDialog::MyDialog(QWidget* parent) : QDialog(parent)
{
	// form a connection between the button and the dialog
	connect(someButtonInTheDialog, SIGNAL(clicked()), this, SIGNAL(someButtonClicked()));
}
