详细描述

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. For example:


  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);
      ...
  }

Action with status tip.

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