	Places a message in the application event loop, then returns without waiting for the window to process the message.

int64_t	SendMessage (unsigned int id, uint64_t wParam=0, int64_t lParam=0)
	Sends a message to the object and does not return until it has processed the message.

void	setFlag (Flag flag, bool on=true)
	Sets some flags on the widget.

bool	SetScrollInfo (Qt::Orientation nBar, ScrollInfo *lpScrollInfo, bool bRedraw=true)
	Sets information about the scroll bar.

int	SetScrollPos (Qt::Orientation nBar, int nPos, bool bRedraw=true)
	Sets the current position of a scroll box and, if specified, redraws the scroll bar to reflect the new position.

void	SetScrollRange (Qt::Orientation nBar, int nMinPos, int nMaxPos, bool bRedraw=true)
	Sets minimum and maximum position values for the given scroll bar.
