WR DELETE TAB


WR DELETE TAB ( area ; tabNum )

Parameter	Type	Description
area	Longint	4D Write area
tabNum	Longint	Tabulation number

Description

The WR DELETE TAB command deletes the tab whose number (counting left-to-right) is passed in tabNum from the 4D Write area referenced by area. If other tabs are located at the same position, they too will be deleted.

Note: If the selection consists of several paragraphs, the tab numbering applies to the last selected paragraph.

Example

You want to remove all the tab stops from your document:

 C_LONGINT(Area;$i;$TabNum;$uniform)

  `Inserting the cursor at the beginning of the area

 WR SET SELECTION(Area;0;0)

  `Counting the number of paragraphs in the document

 NbParag:=WR Count(Area;wr nb paragraphs)

  `Processing each paragraph

 For($i;1;NbParag)

  `Getting the position of the paragraph

    WR GET PARAGRAPHS(Area;START;Pos)

  `Going inside the paragraph

    WR SET SELECTION(Area;START+1;START+1)

  `Getting the number of tab stops

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

    While($TabNum#0)

       WR DELETE TAB(Area;1)

       $TabNum:=$TabNum-1

    End while

  `Repositioning just after the last processed paragraph

    WR GET SELECTION(Area;Pos;Pos)

 End for
