// TXT.CPP
// 
// History:
//		08/07/96 JMI	Started.
//
//		08/12/96	JMI	Now utilizes CGuiItem::DrawText to draw text.
//
//		09/24/96	JMI	Changed all BLU_MB?_* macros to RSP_MB?_* macros.
//
//		10/31/96	JMI	Changed:
//							Old label:		New label:
//							=========		=========
//							CTxt				RTxt
//							CImage			RImage
//							CGuiItem			RGuiItem
//							CENTERED			RGuiItem::Centered
//
//		11/27/96	JMI	Added initialization of m_type to identify this type
//							of GUI item.
//
//		01/01/96	JMI	Compose() no longer sets hot area (now done by base 
//							class).
//
//		01/04/96	JMI	Upgraded HotCall() to new CursorEvent().  This upgrade
//							is in response to RGuiItem now using relative RHots.
//							Now m_hot.m_sX/Y is parent item relative just like
//							m_sX/Y.  This should simplify a lot of stuff and even
//							fix some odd features like being able to click a GUI
//							item that exceeds the boundary of its parent.  This fix
//							will be essential for the not-yet-existent RListBox since
//							it will most likely scroll many children through a small
//							client area.
//							Now there are two regions associated with cursor events.
//							The first is the 'hot' area.  This is the area that m_hot
//							is set to include.  Child items can only receive cursor
//							events through this area.  The second is the 'event' area.
//							This is the area where the item really is actually con-
//							cerned with cursor events.  Example:  For a Dlg, the
//							entire window is the 'hot' area and the title bar is the
//							'event' area.
//
//////////////////////////////////////////////////////////////////////////////
//
// This a GUI item that is based on the basic RGuiItem. 
// This overrides HotCall() to get information about where a click in its RHot
// occurred.
// This overrides Compose() to add text.
//
// Enhancements/Uses:
// To change the look of text when pressed, you may want to override the
// Compose() or DrawBorder() in a derived class.
// To change the background of the text item, see RGuiItem.
// To get a callback on a click/release pair in the text item, set m_tcUser.
