X-Files Components 1.0
 ======================

 X-Files Components 1.0 contains (as yet) one component (TXDBGrid) designed for
 Inprise Delphi 4.

 TXDBGrid is  a functional extension  of standard TDBGrid.  Assumption was that
 TXDBGrid should execute  all standard TDBGrid functions  and a few additional,
 which are turned on by Options or setting values for new properties.  TXDBGrid
 is fully compatible with TDBGrid on properties level and can be used as a rep-
 lacement without  losing existing values.  TXDBGrid has its own  ColumnEditor,
 which can fully support all new properties.


 Overview
 ========

 Additional functions accessible in TXDBGrid:
   + Right mouse button column moving
   + Column titles handled like buttons
   + Showing markers in title area
   + Switching markers between columns
   + Showing multirows headers (common for near columns)
   + Showing multilines text for data, titles and headers
   + Showing word wrapped text for data and titles
   + Vertical text justification for data and titles
   + Ending long text by "..." for data and titles
   + Enable/disable edit for any individual column
   + Data lines count change possibility
   + Showing ftMemo or ftGraphic field into cell
   + Defining width range for any column
   + Defining height range (in data lines) for any row
   + Vertical column synchronization between grids allows creation of
     multilevel footers with several summarization !!!
   + Showing/Hiding horizontal and/or vertical scrollbars
   + Any column moving can be accepted or discarded
   + Searching columns by field name
   + Changing color and font properties for any data cell
   + Drawing pictures into cell
   + Drawing text onto pictures (wallpapers)

   dgRowResize        - enable row resizing
   dgRowScroll        - enable horizontal scrolling by keyboard, if dgRowSelect
                        option is enabled

 Additional Properties and Events accessible in TXDBGrid:
   HeaderColor       - determine background color for column headers
   HeaderFont        - determine font properties for column headers
   HeaderLinesCount  - determine header row height in lines
   LinesCount        - determine data row height in lines
   LinesCountMax     - determine maximum lines count for data row height change
   LinesCountMin     - determine minimum lines count for data row height change
   MasterGrid        - determine master grid for grids synchronization
   ScrollBars        - determine scrollbars handled by TXDBGrid
   TitleLinesCount   - determine title row height in lines
   OnColumnMoving    - determine event allows accepting of column moving
   OnHeaderClick     - determine event user clicks on a header
   OnPaintColumnCell - determine event allows changing of default color, font
                       or image for any data cell

 Additional Properties accessible in TXColumn:
   Ellipsis    - determine ending long data text by "..."
   ImageDraw   - determine image draw type for any column
   QuickDraw   - determine display bitmap without using a palette
   ShowBlob    - determine display ftMemo or ftGraphic field into cell
   ShowEdit    - determine individual edit possibility for any column
   Transparent - determine display image into cell transparently
   VAlignment  - determine vertical justification for data text
   Wallpaper   - determine display data text onto pictures
   WidthMax    - determine maximum width for column width change
   WidthMin    - determine minimum width for column width change
   WordWrap    - determine display word wrapped data text

 Additional Properties accessible in TXTitleColumn:
   Button      - determine using column title as button
   Ellipsis    - determine ending long title text by "..."
   Header      - determine header text for any column
   Marker      - determine showing marker type
   VAlignment  - determine vertical justification for title text
   WordWrap    - determine display word wrapped title text

 Intended changes implemented in TXDBGrid:
   - For original names of class added 'X'
   - For types TDBGridOption and TDBGridOptions added 'X'
   - Corrected title width calculation for last visible column
   - Corrected setting and storing default column width
   - For dgTitleButtons event OnTitleClick is performed in button like style
   - For dgRightMoving column moving doesn't perform event OnTitleClick

 Additional remarks:
   - Character #13 or #10 should be used as lines separator sign
   - Character '|' should be used as header rows separator sign
   - As header rows separate sign, can be used character '|'
   - Headers for columns are merged while rows lines contain identical text
   - Multilines texts cannot be entered by Object Inspector, but it is possible
     to do this in your program or in mode "View as Text" ('Two'#13'lines')
   - Original TDBGrid component  with properties already set can be replaced by
     TXDBGrid  without losing  properties values.  To do this,  you must rename
     component type TDBGrid to TXDBGrid in *.pas file, enter mode "View as Text"
     and rename TDBGrid to TXDBGrid in *.dfm file. After these changes you MUST
     close all project files and reopen it. If your modules contain referencies
     to any class declared in DBGrids, you must added 'X' to these referencies.
     After all, you can remove module DBGrids from 'uses' line.
   - Similarly TXDBGrid can be replaced by TDBGrid too,  but all values entered
     into new properties will be lost. TXDBGrid can work like original TDBGrid,
     if you set new properties to:
     - additional Options to False
     - Button, Ellipsis, ShowBlob, WordWrap to False
     - LinesCount, LinesCountMin, TitleLinesCount to 1
     - LinesCountMax, WidthMin, WidthMax to -1
     - VAlignment to tvTopJustify
     - ScrollBars to ssBoth
     - MasterGrid to Nil
     - ShowEdit to True
     - Marker to tmNone
