WR SET TAB


WR SET TAB ( area ; tabNumber ; position ; alignment ; fillCharacter )

Parameter	Type	Description
area	Longint	4D Write area
tabNumber	Longint	Tabulation number
position	Longint	New tabulation position
alignment	Integer	New value for the tabulation justification
fillCharacter	String	New character selected as fill character

Description

The WR SET TAB command allows you to set the parameters of the tab stop whose number was passed in tabNumber (tabs are counted left to right). The WR SET TAB command will move the tab stop to position and will set the fill character as well as the alignment of the tab stop.

The selected tab stop will be modified for all the paragraphs of the current selection. If a tab stop already exists at the new location it will be replaced by the tab stop you just modified.

position is the distance from the left margin. position is expressed in the current default unit for the document. If you do not want to change the position of the tab stop, pass -1 in the parameter.

alignment specifies the alignment for the tab stop. If you do not want to modify the alignment of the tab, pass -1 in this parameter. Otherwise, you can use the following constants, found in the “WR Tabs” theme:

Constant	Type	Value	Comment
wr left tab	Longint	1	Left aligned
wr centered tab	Longint	2	Centered
wr right tab	Longint	3	Right aligned
wr decimal tab	Longint	4	Decimal
wr vertical separator tab	Longint	5	Vertical separator

fillCharacter can be any character whose code is contained between 33 and 127. This character is displayed in the same font as the modified tab stop.

Example

In the selection, you want to delete the tab stops that are located at 168 points, move tab stops from 252 points to 280 points and assign '$' as fill character:

 C_LONGINT(Area;$i;$Nbtab;$Unit;$uniform;$Justif)

 C_REAL($Pos)

 C_STRING(2;$fill)

 $Nbtab:=WR Get text property(Area;wr tab;$uniform)

  `Storing current unit

 $Unit:=WR Get doc property(Area;wr unit)

 If($Unit#2)

  `Setting unit to points if not already set

    WR SET DOC PROPERTY(Area;wr unit;2)

 End if

 $i:=1

 Repeat

    WR GET TAB(Area;$i;$pos;$Justif;$fill)

    Case of

       :($Pos=168)

  `Deleting tab stops located at 168 points

          WR DELETE TAB(Area;$i)

          $Nbtab:=$Nbtab-1

       :($Pos=252)

  `Moving tab stops located at 252 points to 280 points

          WR SET TAB(Area;$i;280;$Justif;"$")

          $i:=$i+1

    End case

 Until($i=$Nbtab)

  `Going back to original unit

 WR SET DOC PROPERTY(Area;wr unit;$Unit)
