QMessageBox without buttons.

[ashwinbhatks]

I want to display a MessageBox / Dialog with text "Hello World" for 2 seconds and then the message box must exit automatically without any user interaction.

I tried with the following code but is not working. I still get an OK button which i have to press inorder to close the messagebox.

QString lString("HelloWorld");
QMessageBox lMessage(QMessageBox::Information, QString("HelloWorld"), (lString), MessageBox::NoButton, this);
lMessage.setStyleSheet("background: gray");
lMessage.exec();

Thanks in advance for the answer.

If I remember correctly on Desktop QMessagebox without a Button is a QDialog and this should be the same on other platforms.

Why don't you try startTimer(2000) // for 2 sec and re-implement timerEvent to get timer events to close your messagebox.

# startTimer(2000) // before showing message box

#void <ur class>::timerEvent(QTimerEvent *event)
{
this->lMessage->close();
}
I hope it would help you. - Vikas

Yes but still the OK button is displayed. I do not want the OK button to be shown on the screen. Is there any way to hide the OK button in QMessageBox

Yes, simply set the buttons to 0:

QMessageBox m;
m.setStandardButtons(0);

Thank you. We managed to get the same functionality with the help of QLabel.
