SelStart - DFBaseTextEdit

Returns beginning position of selection

Type: Function
Return Data Type: integer

Syntax

Function SelStart Returns integer

Call Example

Get SelStart to integerVariable

Description

Returns beginning position of selection.

Returns the first character position inside the selection. If no text is selected, returns the current position of the caret.

The character position is the zero-based absolute position of the character in the control. The first position in the first line is always 0. So, if the first line in the control contains 20 characters, and the selected text is characters 5 through 10 of the second line, the return value of SelStart will be 25.

Sample

This sample gets the beginning and ending position of the selected text of control oTextEdit1 and then displays the selection range (or length) to the user in a message box.

Procedure ShowSelectionRange
    Integer iSelStart iSelEnd

    Get SelStart of oTextEdit1 to iSelStart
    Get SelEnd of oTextEdit1 to iSelEnd

    Send Info_Box (string(iSelStart) + " to " + string(iSelEnd)) "Range of selected text"
End_Procedure

This class does not have an insert (bold) function, but we can easily add one:

Procedure Insert String sInsertText
    Integer iPos
    String sText

    Get SelStart to iPos
    Send SetSel iPos -1
    Get SelText to sText
    Move (sInsertText + sText) to sText
    Send ReplaceSel sText
End_Procedure

It can be called like this:

Procedure OnClick
    String sText

    Get Value of oInsertTextForm to sText
    Send Insert of oTextEditor sText
End_Procedure

Return Value

Beginning position of selection.
