problem with signals/slots

[vaas]

hey guys.In my application i'm creating an instance of Dialogtest(a dialog i created).so whenever that dialog opens up and the user clicks on the find button it invokes finclicked() slot which will emit a signal .
I used the signal/slot connection mechanism to connect this emitted signal to a slot of the Mainwindow(parent of the dialog).
The code is compiling but when i run the app and press the find button of the dialog it gives the following error in Application output.



Object::connect: No such signal Dialogtest::csearch(const QString& a,Qt::CaseSensitivity cs)
Object::connect: (sender name: 'Dialogtest')
Object::connect: (receiver name: 'MainWindow')
Object::connect: No such signal Dialogtest::csearch(const QString& a,Qt::CaseSensitivity cs,const QString& c)
Object::connect: (sender name: 'Dialogtest')
Object::connect: (receiver name: 'MainWindow')


Dialogtest.h is:

.........
signals:
    void csearch(const QString&,Qt::CaseSensitivity cs);
    void csearch(const QString&,Qt::CaseSensitivity cs,const QString&);
 
private slots:
    void enablefind();
    void findclicked();
........

.........
signals:
    void csearch(const QString&,Qt::CaseSensitivity cs);
    void csearch(const QString&,Qt::CaseSensitivity cs,const QString&);

private slots:
    void enablefind();
    void findclicked();
........

Dialogtest.cpp

if(ui->replaceEdit->isEnabled()){
      rstring =ui->replaceEdit->text();
        emit csearch(fstring,cs,rstring);
                       }
  else{
      emit csearch(fstring,cs);}

if(ui->replaceEdit->isEnabled()){
      rstring =ui->replaceEdit->text();
        emit csearch(fstring,cs,rstring);
                       }
  else{
      emit csearch(fstring,cs);}

the slots sear() are defined in Mainwindow.cpp
plz help me with this.
