Title: cursor position in a RTF-control
Post by: Christoph Embacher on May 30, 2010, 07:10:22 AM
How can I ensure the cursor is positioned at the end of the text in a RTF-Control? In an Text-Box I tried the code below and it works fine. But these FF-functions aren't available for the RTF-control. Thanks a lot for any help.

                           ByVal UserData As Long _  ' optional user defined Long value
                           ) As Long


  Local sTemp As String
  Local lCount As Long
  Local i         As Long
   
  sTemp = FF_ClipboardGetText
  FF_TextBox_SetText (HWND_FRMMAIN_TEXT1, stemp)

  lcount = FF_TextBox_GetLineCount (HWND_FRMMAIN_TEXT1)
 
  For i =1 To lcount
    FF_TextBox_Scroll (HWND_FRMMAIN_TEXT1, %SB_LINEDOWN)
  Next
 
  FF_TextBox_SetSel (HWND_FRMMAIN_TEXT1, Len(sTemp), Len(sTemp))
 
End Function

I tried your code on a rtf sample test project and it positioned the cursor correctly at the end of the text. Actually, there should be no need to use the FF_TextBox_Scroll for/next loop because the richedit control should automatically scroll the cursor into view when you set the position via FF_TextBox_SetSel (I think).

The FF_TextBox_SetSel function uses an internal SendMessage call to the control using the %EM_SETSEL winapi message. The winapi help for that message states:

"The EM_SETSEL message selects a range of characters in an edit control. You can send this message to either an edit control or a rich edit control.

Thank you, Paul, you are right. I didn't know, that I could use thr FF-TextBox-functions in the same way for the rtf-control.
