Dont see new signal on outside class
-
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.

MyTextEdit::MyTextEdit(QWidget *parent = 0) : QTextEdit(parent)
{
isEdited = false;
}
