Hi,

I have a requirement to display gif with a label(from widget.cpp). The label is present in another ui(displayads.ui). I am able to display an image with this label but the gif is not displaying. The image & gif I am assigning from widget.cpp. displayads.ui contains two labels, one for image display and one for gif display. For this I have commented Ui::displayads *ui & destructor from displayads.h & displayads.cpp. The code is given below.

I am closing this objdispads after 3 seconds but my requirement is to close this from another function of Widget. Can you please help me to display GIF and closing this objdispads from another function.

What I have tried:

As above mentioned

Widget.cpp

///////////// for image display  //////////////

void Widget::Displayads()
{
  displayads *objdispads = new displayads(this);
    
  QPixmap pix1("/root/img.png");
  objdispads->ui->adlabel1->setPixmap(pix1);
  objdispads->ui->adlabel1->setScaledContents( true );
  objdispads->ui->adlabel1->setSizePolicy( QSizePolicy::Ignored, QSizePolicy::Ignored );

          //////////   code for gif display    /////////

    QMovie *movie = new QMovie("/root/swachbt.gif");
    if (!movie->isValid())
    {
        qDebug()<<"Movie is Inavlid";
    }
    objdispads->ui->adlabel2->setMovie(movie);
    movie->start();

    objdispads->show();

    QCoreApplication::processEvents();
    QCoreApplication::processEvents();

    sleep(3);
    objdispads->close();
    objdispads->deleteLater();
}

displayads.cpp

#include "displayads.h"
#include "ui_displayads.h"

displayads::displayads(QWidget *parent) :
QWidget(parent),
ui(new Ui::displayads)
{
    ui->setupUi(this);
    this->setWindowFlags(Qt::FramelessWindowHint);
    ui->adlabel1->setAutoFillBackground(true);
//  ui->adlabel2->setAutoFillBackground(true);
}

//displayads::~displayads()
//{
// delete ui;
//}

displayads.h

#ifndef DISPLAYADS_H
#define DISPLAYADS_H

#include <qwidget>

namespace Ui {
class displayads;
}

class displayads : public QWidget
{
    Q_OBJECT
    
public:
    explicit displayads(QWidget *parent = 0);

    Ui::displayads *ui;

//    ~displayads();
    
private:
//    Ui::displayads *ui;
};

#endif // DISPLAYADS_H
