QAccessibleEvent¶
Detailed Description¶
The PySide.QtGui.QAccessibleEvent class is used to query addition accessibility information about complex widgets.
The event can be of type QEvent.AccessibilityDescription or QEvent.AccessibilityHelp .
Some QAccessibleInterface implementations send QAccessibleEvents to the widget they wrap to obtain the description or help text of a widget or of its children. The widget can answer by calling PySide.QtGui.QAccessibleEvent.setValue() with the requested information.
The default QWidget.event() implementation simply sets the text to be the widget’s tooltip (for AccessibilityDescription event) or its "What's This?" text (for AccessibilityHelp event).
