Hi,

How to write correct defination of delete picture from default system picture .Here is below my code in C++ :

void deleteFile()
{

    QString parameter ="/storage/sdcard0/Pictures/{CB6942CE-8FDE-B00F-A07E-832ECAE05AF4}_1.jpg"
   // QString parameter ="file:///storage/sdcard0/Pictures/{CB6942CE-8FDE-B00F-A07E-832ECAE05AF4}_1.jpg"

     bool state=QFile::remove(parameter);

     if(state==true)
     {
         qDebug() << "delete successful";
     }
     else
     {
         qDebug() << "delete unsuccessful";
     }

}

Both of them parameter paths I've tried but ppplication output is like below:

D/OfflineTests( 4216): (null):0 ((null)): delete unsuccessful

How can I write correct delete code ?

Thanks

Hi!
Are you sure the file you want to delete actually exists? The following works for me:

void MainForm::on_pushButton_clicked()
{
    const QString fileName = QString("%1/myfile.txt").arg( QStandardPaths::writableLocation(QStandardPaths::DocumentsLocation) );
    ui->pushButton->setText( QFile::remove(fileName) ? ":-)" : ":-(" );
}
