Facing problem in creating new cpp and Header file

[parulkalra14]

I want to create cpp and header file for this function.

void MainWindow::labtext()//labeltext function
{
    if(cursor.block().text().contains("",Qt::CaseInsensitive))
   {
           ui->label->setText("");
 
   }
 
 
    if(cursor.block().text().contains("printf",Qt::CaseInsensitive)&& cursor.block().text().contains("(",Qt::CaseInsensitive)||cursor.block().text().contains("cout",Qt::CaseInsensitive)&&cursor.block().text().contains("<<",Qt::CaseInsensitive))
   {
           ui->label->setText("Printing to Standard Output");
   }
 
    else if(cursor.block().text().contains("while",Qt::CaseInsensitive)&& cursor.block().text().contains("(",Qt::CaseInsensitive))
   {
       ui->label->setText("Checking condition for While Statement");
       //QMessageBox::critical(this,"oo","fdgffh");
   }
 
 
 
 
    else if(cursor.block().text().contains("switch",Qt::CaseInsensitive)&&cursor.block().text().contains("(",Qt::CaseInsensitive))
   {
       ui->label->setText("Checking condition for Switch Statement");
   }
   else if(cursor.block().text().contains("if",Qt::CaseInsensitive)&&cursor.block().text().contains("(",Qt::CaseInsensitive)&&(!cursor.block().text().contains(";",Qt::CaseInsensitive)))
   {
       ui->label->setText("Checking condition for If Statement");
   }
    else if(cursor.block().text().contains("else",Qt::CaseInsensitive)&& cursor.block().text().contains("if",Qt::CaseInsensitive))
   {
       ui->label->setText("Checking condition for If Statement");
 
   }
 
    else if(cursor.block().text().contains("else",Qt::CaseInsensitive))
   {
       ui->label->setText("Checking condition for Else Statement");
 
   }
}

void MainWindow::labtext()//labeltext function
{
    if(cursor.block().text().contains("",Qt::CaseInsensitive))
   {
           ui->label->setText("");

   }


    if(cursor.block().text().contains("printf",Qt::CaseInsensitive)&& cursor.block().text().contains("(",Qt::CaseInsensitive)||cursor.block().text().contains("cout",Qt::CaseInsensitive)&&cursor.block().text().contains("<<",Qt::CaseInsensitive))
   {
           ui->label->setText("Printing to Standard Output");
   }

    else if(cursor.block().text().contains("while",Qt::CaseInsensitive)&& cursor.block().text().contains("(",Qt::CaseInsensitive))
   {
       ui->label->setText("Checking condition for While Statement");
       //QMessageBox::critical(this,"oo","fdgffh");
   }




    else if(cursor.block().text().contains("switch",Qt::CaseInsensitive)&&cursor.block().text().contains("(",Qt::CaseInsensitive))
   {
       ui->label->setText("Checking condition for Switch Statement");
   }
   else if(cursor.block().text().contains("if",Qt::CaseInsensitive)&&cursor.block().text().contains("(",Qt::CaseInsensitive)&&(!cursor.block().text().contains(";",Qt::CaseInsensitive)))
   {
       ui->label->setText("Checking condition for If Statement");
   }
    else if(cursor.block().text().contains("else",Qt::CaseInsensitive)&& cursor.block().text().contains("if",Qt::CaseInsensitive))
   {
       ui->label->setText("Checking condition for If Statement");

   }

    else if(cursor.block().text().contains("else",Qt::CaseInsensitive))
   {
       ui->label->setText("Checking condition for Else Statement");

   }
}

To copy to clipboard, switch view to plain text mode 

Can anybody help me?
I tried this code:

// For header file
 
#ifndef LABELTEXT_H
#define LABELTEXT_H
 
 
#include <QLabel>
 
 
class QLabel;
 
class Labeltext : public QLabel
{
    Q_OBJECT
 
public:
    Labeltext(QLabel *parent = 0);
 
protected:
    void labtext();
 
private:
 
};
 
#endif // LABELTEXT_H

// For header file

#ifndef LABELTEXT_H
#define LABELTEXT_H


#include <QLabel>


class QLabel;

class Labeltext : public QLabel
{
    Q_OBJECT

public:
    Labeltext(QLabel *parent = 0);

protected:
    void labtext();

private:

};

#endif // LABELTEXT_H

To copy to clipboard, switch view to plain text mode 

but in cpp file i dont know what to include in constructor?
