public class QHoverEvent
The QHoverEvent class contains parameters that describe a mouse event.
Mouse events occur when a mouse cursor is moved into, out of, or within a widget, and if the widget has the Qt::WA_Hover attribute.
The function pos gives the current cursor position, while oldPos gives the old mouse position.

public QHoverEvent(QEvent.Type type, QPoint pos, QPoint oldPos)
Constructs a hover event object.

Method Detail |
---|
public final QPoint oldPos()
Returns the previous position of the mouse cursor, relative to the widget that received the event. If there is no previous position, oldPos will return the same position as pos.
On QEvent::HoverEnter events, this position will always be QPoint(-1, -1).
public final QPoint pos()
Returns the position of the mouse cursor, relative to the widget that received the event.
On QEvent::HoverLeave events, this position will always be QPoint(-1, -1).
public static QHoverEvent fromNativePointer(QNativePointer nativePointer)
nativePointer
- the QNativePointer of which object should be returned.
