Re: Restoring the vertical position

Thank you for your help Mitchell.

Here is a sample of my AutoHotkey code. The function SetEditorText() gets 
the current vertical position, replace the editor with the new text and 
tries to restore the vertical position.

;---------------------------------------------------------
SetEditorText(strNewText, intStart, intEnd)
;---------------------------------------------------------
{
; o_Sci is an AutoHotkey class wrapper for Scintilla commands messages

intFirstVisibleLine := o_Sci.GETFIRSTVISIBLELINE()
intDocLineFromVisible := o_Sci.DOCLINEFROMVISIBLE(intFirstVisibleLine) 

o_Sci.SETTEXT("", strNewText, 1)

o_Sci.SETSEL(intStart, intEnd)
o_Sci.VISIBLEFROMDOCLINE(intDocLineFromVisible)
}
;---------------------------------------------------------

The current result with this code is that regardless of the original 
position of the selected text in the visible portion (middle or bottom of 
the window), the selection vertical position is always restored at the top 
of the window (first visible line). See the example attached where the 
selected text has been converted to uppercase.

Thanks,
Jean
