qml 弹窗,如何在Qt中弹出消息窗口？

I have to pop up a message in Qt when a particular test case is executed. Since I am a beginner in Qt, I do not want to risk trying with a qml...

How can I do it (directly in .cpp file) without creating a qml file?

If you want to display a simple message, you can use a QMessageBox::information.

Following the provided link, you can call a message box of that type this way:

QMessageBox::information(

this,

tr("Application Name"),

tr("An information message.") );

Edit: Since this question had a lot of visits during these years, I just wanted to include the other types of message for the sake of information (again, taken by the link above):

QMessageBox::warning(

this,

tr("Application Name"),

tr("A warning message.") );

QMessageBox::critical(

this,

tr("Application Name"),

tr("A critical message.") );

switch( QMessageBox::question(

this,

tr("Application Name"),

tr("An information message."),

QMessageBox::Yes |

QMessageBox::No |

QMessageBox::Cancel,

QMessageBox::Cancel ) )

{

case QMessageBox::Yes:

qDebug( "yes" );

break;

case QMessageBox::No:

qDebug( "no" );

break;

case QMessageBox::Cancel:

qDebug( "cancel" );

break;

default:

qDebug( "close" );

break;

}
