Dont see new signal on outside class

Pablik2005

Hi,
I reimpement QTextEdit:

.h
[code]
#ifndef MYTEXTEDIT_H
#define MYTEXTEDIT_H

#include <QtGui>
#include <QtCore>

class MyTextEdit : public QTextEdit
{
Q_OBJECT
public:
explicit MyTextEdit(QWidget *parent);

private:
bool isEdited;

signals:
void signalMouseDoubleClickEvent(QMouseEvent *e);

public slots:

protected:
void mouseDoubleClickEvent(QMouseEvent *e);
};

#endif // MYTEXTEDIT_H
[/code]

.cpp
[code]
#include "mytextedit.h"

MyTextEdit::MyTextEdit(QWidget *parent)
{
setParent( parent );
isEdited = false;

}

void MyTextEdit::mouseDoubleClickEvent(QMouseEvent *e)
{
QTextEdit::mouseDoubleClickEvent(e);
if( !anchorAt( e->pos() ).isEmpty() )
emit signalMouseDoubleClickEvent(e);
}
[/code]

now if i declar new verbal MyTextEdit type then no have signal i dont know why. Is somting like public and prtected signal ???

main.cpp
[code]
MyTextEdit *TextEdit;
TextEdit = new MyTextEdit(this);

connect(TextEdit, SIGNAL(),

[/code]

Your post breaks with the interesting part. How do you connect your signal?
Give the complete statement.
Do you get an error message?

Signals are always protected from a technical point of view (only the class itself and its subclasses can emit them), and always public from a logical point of view (everyone can connect to a signal).

The code you've posted works correctly. Make sure that you've included the header file mytextedit.h (no forward declaration) and that you've re-run qmake after adding the signal.

In addition, you are missing a call to the base class constructor.
