Unsolved QLabel clearing pixmap when QFileDialog is selected.
-
I have a label and a pushButton which sets image to the label on clicked.If label initially has a image set and If the button is clicked the label gets cleared even before selecting image from the FileDialog.
Below is the code
void MainWindow::on_backgroundImageBrowse_clicked()
{qstrFileName = QFileDialog::getOpenFileName ( this, "file", "~/", tr ("Image (*.bmp *.jpg );;All files (*.*)") ); m_ZoneManager->GUI_generalstruct->generalBackgroundImage = qstrFileName; QPixmap pix (m_ZoneManager->GUI_generalstruct->generalBackgroundImage); ui->label->setStyleSheet ("border-image:url(m_ZoneManager->GUI_generalstruct->generalBackgroundImage);"); int w = 1280; int h = 720; ui->label->setPixmap (pix.scaled (w, h)); //,Qt::KeepAspectRatio
}
Even If cancel is clicked in the fileDialog the label is getting cleared.Please suggest

@Sriu1 Please read http://doc.qt.io/qt-5/qfiledialog.html#getOpenFileName
"If the user presses Cancel, it returns a null string."
I don't see you checking whether qstrFileName is a null string or not.
Also this line does not make any sence:ui->label->setStyleSheet ("border-image:url(m_ZoneManager->GUI_generalstruct->generalBackgroundImage);");
