[править] Подробное описание

The QStatusTipEvent class provides an event that is used to show messages in a status bar.

Status tips can be set on a widget using the QWidget::setStatusTip() function. They are shown in the status bar when the mouse cursor enters the widget. Пример:

 MainWindow::MainWindow(QWidget *parent)
     : QMainWindow(parent)
 {
     QWidget *myWidget = new QWidget;
     myWidget->setStatusTip(tr("This is my widget."));
 
     setCentralWidget(myWidget);
     ...
 }

Status tips can also be set on actions using the QAction::setStatusTip() function:

 MainWindow::MainWindow(QWidget *parent)
     : QMainWindow(parent)
 {
     QMenu *fileMenu = menuBar()->addMenu(tr("File"));
 
     QAction *newAct = new QAction(tr("&New"), this);
     newAct->setStatusTip(tr("Create a new file."));
     fileMenu->addAction(newAct);
     ...
 }

Finally, status tips are supported for the item view classes through the Qt::StatusTipRole enum value.
