[Anshuman]

ok this is my code..


class PainterApp : public QDialog,public QCalendarWidget
{
Q_OBJECT

public:
explicit PainterApp(QWidget *parent = 0);
~PainterApp();

private:
Ui::PainterApp *ui;
private slots:
void paintEvent(QPaintEvent *);
};


void PainterApp::paintCell(QPainter * painter, const QRect & rect, const QDate & date ) const{

QRectF target(30.0, 40.0, 80.0, 60.0);
QRectF source(30.0, 40.0, 70.0, 40.0);
QImage image("C:/QTWork/back-icon.png");


painter.drawImage(target, image, source);
ui->calendarWidget->paintCell(painter,rect,date.currentDate());

}

It's because of the multiple inheritance. You should avoid multiple inheritance except in the case of pure virtual classes.(interfaces)

Both QDialog and QCalendarWidget have a show function so when PainterApp::show is called it doesn't know whether to call the show from QDialog or from QCalendarWidget.

Redesign your class to only extend QDialog and add a QCalendarWidget to it's ui.

ok I am sending my code u please check it..now no error signifies but nothing display in the cell..


namespace Ui {
class PainterApp;
}
class MyCalendarWidget : public QCalendarWidget
{
private:
Ui::PainterApp *ui;
protected:
virtual void paintCell(QPainter* painter, const QRectF& rect, const QDate& date);

};
class PainterApp : public QDialog
{
Q_OBJECT

public:
explicit PainterApp(QWidget *parent = 0);
~PainterApp();

private:
Ui::PainterApp *ui;
private slots:

};



#include "painterapp.h"
#include "ui_painterapp.h"

PainterApp::PainterApp(QWidget *parent) :
QDialog(parent),
ui(new Ui::PainterApp)
{
ui->setupUi(this);

}
void MyCalendarWidget::paintCell(QPainter* painter, const QRectF& rect, const QDate& date)
{

rect(30.0, 40.0, 80.0, 60.0);
QImage image("C:/QTWork/back-icon.png");


painter->drawImage(rect, image, rect);
ui->calendarWidget->paintCell(painter,rect,date.currentDate());
}
