DevOut

Writes a value to the current device

Syntax

      DevOut( <expression>, [<cColor>], [<nRow>, <nCol>] ) --> NIL

Arguments

<expression> : Any valid expression to write to the device assigned by SET DEVICE command

<cColor> : A valid color codes string for value to write. Default is current color setting <nRow> and

<nCol> : Row and column value for device to write <expression>. Defaults is ROW() and COL() if current device is screen and PRow() and PCol() for the printer.

Return

DevOut() returns always NIL

Description

DevOut() is a console function that outputs the value of an expression to the screen or the printer depending on current device.

Example

      // Write a string at upper left corner of screen :

      DevOut( "Here is upper left corner", "W+/R", 0, 0  )

        Equivalent usage :

      @ 0, 0 SAY "Here is upper left corner" COLOR "W+/R"

Transform()

Posted on by vivaclipper

Transform()

Formats a value based on a specific picture template.

Syntax

      Transform( <xExpression>,  <cTemplate> )  --> cFormatted

Arguments

<xExpression> Any expression to be formated.

<cTemplate> Character string with picture template

Returns

<cFormatted> Formatted expression in character format

Description

This function returns <xExpression> in the format of the picture expression passed to the function as <cTemplate>.

Their are two components that can make up <cTemplate> : a function string and a template string. Function strings are those functions that globally tell what the format of <xExpression> should be. These functions are represented by a single character precede by the @ symbol.

There are a couple of rules to follow when using function strings and template strings:

– First, a single space must fall between the function template and the template string if they are used in conjunction with one another.

– Second, if both components make up the value of <cTemplate>, the function string must precede the template string. Otherwise, the function string may appear with out the template string and vice versa.

The table below shows the possible function strings available with the Transform() function.

      @B   Left justify the string within the format.
      @C   Issue a CR after format is numbers are positive.
      @D   Put dates in SET DATE format.
      @E   Put dates in BRITISH format.
      @L   Make a zero padded string out of the number.
      @R   Insert non template characters.
      @X   Issue a DB after format is numbers are negative.
      @Z   Display any zero as blank spaces.
      @(   Quotes around negative numbers
      @!   Convert alpha characters to uppercased format.

The second part of <cTemplate> consists of the format string. Each character in the string may be formatted based on using the follow characters as template markers for the string.

      A,N,X,9,#   Any data type
      L           Shows logical as "T" or "F"
      Y           Shows logical as "Y" or "N"
      !           Convert to uppercase
      $           Dollar sing in place of leading spaces in 
                  numeric expression
      *           Asterisks in place of leading spaces in 
                  numeric expression
      ,           Commas position
      .           Decimal point position

Examples

      LOCAL cString := "This is harbour"
      LOCAL nNumber := 9923.34
      LOCAL nNumber1 := -95842.00
      LOCAL lValue := .T.
      LOCAL dDate := Date()
      ? "working with String"
      ? "Current String is",  cString
      ? "All uppercased",  Transform( cString,  "@!" )
      ? "Date is",  ddate
      ? "Date is ",  Transform( ddate,  "@D" )
      ? Transform( nNumber,  "@L 99999999" )  //  "009923.34"
      ? Transform( 0      ,  "@L 9999"     )  //  "0000"

 DEVOUTPICT()
 Write a value to the current device using a picture clause
------------------------------------------------------------------------------
 Syntax

     DEVOUTPICT(<exp>, <cPicture>, [<cColorString>])
        --> NIL

 Arguments

     <exp> is the value to display.

     <cPicture> defines the formatting control for the display of <exp>.
     The picture specified here is the same as one used with @...SAY or
     TRANSFORM and can include both templates and functions.

     <cColorString> is an optional argument that defines the display
     color of <exp>.  If the current DEVICE is SCREEN, output displays in the
     specified color.

     If not specified, <exp> displays as the standard color of the current
     system color as defined by SETCOLOR().  <cColorString> is a character
     expression containing the standard color setting.  If you want to
     specify a literal color setting, it must be enclosed in quote marks.

 Returns

     DEVOUTPICT() always returns NIL.

 Description

     DEVOUTPICT() is a full-screen display function that writes the value of
     a single expression to the current device at the current cursor or
     printhead position.  DEVOUTPICT() is used in combination with DEVPOS()
     in Std.ch to implement the @...SAY command used with a PICTURE clause.

 Examples

     .  This example shows the relationship between the DEVOUTPICT()
        function and the @...SAY command:

        DEVPOS(10, 10)
        DEVOUTPICT("Hello there", "@!", "BG+/B"))
        //
        @ 10, 10 SAY "Hello there" PICTURE "@!" COLOR "BG+/B"

Browse Classes :

TBrowse :

Provides objects for browsing table-oriented data.

Description :

A TBrowse object is a general purpose browsing mechanism for table-oriented data. TBrowse objects provide a sophisticated architecture for acquiring, formatting, and displaying data. Data retrieval and file positioning are performed via user-supplied code blocks, allowing a high degree of flexibility and interaction between the browsing mechanism and the underlying data source. The format of individual data items can be precisely controlled via the TBColumn data retrieval code blocks; overall display formatting and attributes can be controlled by sending appropriate messages to the TBrowse object.

A TBrowse object relies on one or more TBColumn objects. A TBColumn object contains the information necessary to define a single column of the browse table (see TBColumn class in this chapter).

During operation, a TBrowse object retrieves data by evaluating code blocks. The data is organized into rows and columns and displayed within a specified rectangular region of the screen. The TBrowse object maintains an internal browse cursor. The data item on which the browse cursor rests is displayed in a highlighted color. (The actual screen cursor is also positioned to the first character of this data item.)

Initially, the browse cursor is placed on the data item at the top left of the browse display. Messages can then be sent to the TBrowse object to navigate the displayed data, causing the browse cursor to move. These messages are normally sent in response to user keystrokes.

New data is automatically retrieved as required by navigation requests. When navigation proceeds past the edge of the visible rectangle, rows or columns beyond that edge are automatically brought into view. When new rows are brought into view, the underlying data source is repositioned by evaluating a code block.

Note: TBrowse objects do not clear the entire window before output during redisplay operations. Part of the window may still be cleared when data from the existing display is scrolled.

Class Functions :

TBrowseNew() :

Create a new TBrowse object

 TBrowseNew(<nTop>, <nLeft>, <nBottom>, <nRight>)
 --> objTBrowse

Returns a new TBrowse object with the specified coordinate settings. The TBrowse object is created with no columns and no code blocks for data positioning. These must be provided before the TBrowse object can be used.

TBrowseDB() :

Create a new TBrowse object for browsing a database file

 TBrowseDB(<nTop>, <nLeft>, <nBottom>, <nRight>)
 --> objTBrowse

Returns a new TBrowse object with the specified coordinate settings and default code blocks for data source positioning within database files. The default code blocks execute the GO TOP, GO BOTTOM, and SKIP operations.

Note that TBrowseDB() creates an object with no column objects. To make the TBrowse object usable, you must add a column for each field to be displayed

Exported Instance Variables:

autoLite : Logical value to control highlighting
cargo : User-definable variable
colCount : Number of browse columns
colorSpec : Color table for the TBrowse display
colPos : Current cursor column position
colSep : Column separator character
footSep : Footing separator character
freeze : Number of columns to freeze
goBottomBlock : Code block executed by TBrowse:goBottom()
goTopBlock : Code block executed by TBrowse:goTop()
headSep : Heading separator character
hitBottom : Indicates the end of available data
hitTop : Indicates the beginning of available data
leftVisible : Indicates position of leftmost unfrozen column in display
nBottom : Bottom row number for the TBrowse display
nLeft : Leftmost column for the TBrowse display
nRight : Rightmost column for the TBrowse display
nTop : Top row number for the TBrowse display
rightVisible : Indicates position of rightmost unfrozen column in display
rowCount : Number of visible data rows in the TBrowse display
rowPos : Current cursor row position
skipBlock : Code block used to reposition data source
stable : Indicates if the TBrowse object is stable

Exported Methods:

Cursor Movement Methods :

down() : Moves the cursor down one row
end() : Moves the cursor to the rightmost visible data column
goBottom() : Repositions the data source to the bottom of file
goTop() : Repositions the data source to the top of file
home() : Moves the cursor to the leftmost visible data column
left() : Moves the cursor left one column
pageDown() : Repositions the data source downward
pageUp() : Repositions the data source upward
panEnd() : Moves the cursor to the rightmost data column
panHome() : Moves the cursor to the leftmost visible data column
panLeft() : Pans left without changing the cursor position
panRight() : Pans right without changing the cursor position

up() : Moves the cursor up one row

Miscellaneous Methods :

addColumn() : Adds a TBColumn object to the TBrowse object
colorRect() : Alters the color of a rectangular group of cells
colWidth() : Returns the display width of a particular column
configure() : Reconfigures the internal settings of the TBrowse object

invalidate() : Forces redraw during next stabilization
refreshAll() : Causes all data to be refreshed during the next stabilize
refreshCurrent() : Causes the current row to be refreshed on next stabilize
setColumn() : Replaces one TBColumn object with another
stabilize() : Performs incremental stabilization

TBColumn :

Provides the column objects TBrowse objects.

Description :

A TBColumn object is a simple object containing the information needed to fully define one data column of a TBrowse object (see the TBrowse reference in this chapter). TBColumn objects have no methods, only exported instance variables.

Class Function :

TBColumnNew() :

Create a new TBColumn object.

TBColumnNew(<cHeading>, <bBlock>) --> objTBColumn

Exported Instance Variables :

block : Code block to retrieve data for the column
cargo : User-definable variable
colorBlock : Code block that determines color of data items
colSep : Column separator character
defColor : Array of numeric indexes into the color table
footing : Column footing
footSep : Footing separator character
heading : Column heading
headSep : Heading separator character
width : Column display width

Example :

This example is a code fragment that creates a TBrowse object and adds some TBColumn objects to it:

USE Customer NEW
//
// Create a new TBrowse object
objBrowse := TBrowseDB(1, 1, 23, 79)
//
// Create some new TBColumn objects and
// add them to the TBrowse object
objBrowse:addColumn(TBColumnNew( "Customer", ;
                    {|| Customer->Name} ))
objBrowse:addColumn(TBColumnNew( "Address", ;
                    {|| Customer->Address} ))
objBrowse:addColumn(TBColumnNew( "City", ;
                    {|| Customer->City} ))
.
. <statements to actually browse the data>
.
CLOSE Customer
