Subclassing a QPushButton

[Rajeshkhan]

I subclassed a QPushButton and in the constructor I changed the text of QPushButton however the text does not change in the actual button any suggestions on why the text is not changing ?

#ifndef QCUSTOMPUSHBUTTON
#define QCUSTOMPUSHBUTTON
 
 
#include "QObject"
#include "QPushButton"
 
class QCustomPushBtton : public QPushButton
{
    Q_OBJECT
 
    public:
    QCustomPushBtton(QWidget *parent=0):QPushButton(parent)
    {
           this->setText("testing123");
    }
 
    signals:
    void DoubleClick();
 
   protected:
    virtual void mouseDoubleClickEvent(QMouseEvent *) override
    {
        emit DoubleClick();
    }
};
 
 
#endif // QCUSTOMPUSHBUTTON

#ifndef QCUSTOMPUSHBUTTON
#define QCUSTOMPUSHBUTTON


#include "QObject"
#include "QPushButton"

class QCustomPushBtton : public QPushButton
{
    Q_OBJECT

    public:
    QCustomPushBtton(QWidget *parent=0):QPushButton(parent)
    {
           this->setText("testing123");
    }

    signals:
    void DoubleClick();

   protected:
    virtual void mouseDoubleClickEvent(QMouseEvent *) override
    {
        emit DoubleClick();
    }
};


#endif // QCUSTOMPUSHBUTTON

To copy to clipboard, switch view to plain text mode
